Stuttering - How To Cure A Stutter

Stuttering, also known as stammering, is a speech disorder in which the flow of speech is disrupted by involuntary repetitions and prolongations of sounds, syllables, words or phrases as well as involuntary silent pauses or blocks in which the person who stutters is unable to produce sounds. The term stuttering is most commonly associated with involuntary sound repetition, but it also encompasses the abnormal hesitation or pausing before speech, referred to by people who stutter as blocks, and the prolongation of certain sounds, usually vowels or semivowels. According to Watkins et al., stuttering is a disorder of "selection, initiation, and execution of motor sequences necessary for fluent speech production." For many people who stutter, repetition is the primary problem. The term "stuttering" covers a wide range of severity, encompassing barely perceptible impediments that are largely cosmetic to severe symptoms that effectively prevent oral communication. In the world, approximately four times as many men as women stutter, encompassing 70 million people worldwide, or about 1% of the world's population.

The impact of stuttering on a person's functioning and emotional state can be severe. This may include fears of having to enunciate specific vowels or consonants, fears of being caught stuttering in social situations, self-imposed isolation, anxiety, stress, shame, being a possible target of bullying (especially in children), having to use word substitution and rearrange words in a sentence to hide stuttering, or a feeling of "loss of control" during speech. Stuttering is sometimes popularly seen as a symptom of anxiety, but there is actually no direct correlation in that direction (though as mentioned the inverse can be true, as social anxiety may actually develop in individuals as a result of their stuttering).

Stuttering is generally not a problem with the physical production of speech sounds or putting thoughts into words. Acute nervousness and stress do not cause stuttering, but they can trigger stuttering in people who have the speech disorder, and living with a stigmatized disability can result in anxiety and high allostatic stress load (chronic nervousness and stress) that reduce the amount of acute stress necessary to trigger stuttering in any given person who stutters, exacerbating the problem in the manner of a positive feedback system; the name 'stuttered speech syndrome' has been proposed for this condition. Neither acute nor chronic stress, however, itself creates any predisposition to stuttering.

The disorder is also variable, which means that in certain situations, such as talking on the telephone or in a large group, the stuttering might be more severe or less, depending on whether or not the stutterer is self-conscious about their stuttering. Stutterers often find that their stuttering fluctuates and that they have "good" days, "bad" days and "stutter-free" days. The times in which their stuttering fluctuates can be random. Although the exact etiology, or cause, of stuttering is unknown, both genetics and neurophysiology are thought to contribute. There are many treatments and speech therapy techniques available that may help decrease speech disfluency in some people who stutter to the point where an untrained ear cannot identify a problem; however, there is essentially no cure for the disorder at present. The severity of the person's stuttering would correspond to the amount of speech therapy needed to decrease disfluency. For severe stuttering, long-term therapy and hard work is required to decrease disfluency.

Primary behaviors

Primary stuttering behaviors are the overt, observable signs of speech disfluencies, including repeating sounds, syllables, words or phrases, silent blocks and prolongation of sounds. These differ from the normal dysfluencies found in all speakers in that stuttering dysfluencies may last longer, occur more frequently, and are produced with more effort and strain. Stuttering dysfluencies also vary in quality: common dysfluencies tend to be repeated movements, fixed postures, or superfluous behaviors. Each of these three categories is composed of subgroups of stutters and dysfluencies.

Repeated movements
- Part-word repetitionâ€"a single segment of a word is repeated (for example: s-s-stuttering!) or a part of a word which is still a full syllable such as "unâ€"unâ€"under the..." and "oâ€"oâ€"open".
- Incomplete syllable repetitionâ€"an incomplete syllable is repeated, such as a consonant without a vowel, for example, "câ€"câ€"câ€"cold".
- Whole-word repetitionâ€"a whole word, or more than one word is repeated, such as "I knowâ€"I knowâ€"I know a lot of information.".
Fixed postures
- Prolongation>â€"prolongation of a sound occurs such as "mmmmmmmmmom".
- Blockâ€"such as a block of speech or a tense pause where nothing is said despite efforts.
Superfluous behaviors
- Interjectionsâ€"this includes an interjection such as an unnecessary uh or um as well as revisions, such as going back and correcting one's initial statements such as "Iâ€"My girlfriend...", where the I has been corrected to the word my.
- Secondary characteristicsâ€"these are visible or audible speech behaviors, such as lip smacking, throat clearing, head thrusting, etc., usually representing an effort to break through or circumvent a block or stuttering loop.

Variability

The severity of a stutter is often not constant even for people who severely stutter. People who stutter commonly report dramatically decreased disfluency when talking in unison with another speaker, copying another's speech, whispering, singing, and acting or when talking to pets, young children, or themselves. Other situations, such as public speaking and speaking on the telephone, are often greatly feared by people who stutter, and increased stuttering is reported.

Feelings and attitudes

Stuttering could have a significant negative cognitive and affective impact on the person who stutters. It has been described in terms of the analogy to an iceberg, with the immediately visible and audible symptoms of stuttering above the waterline and a broader set of symptoms such as negative emotions hidden below the surface. Feelings of embarrassment, shame, frustration, fear, anger, and guilt are frequent in people who stutter, and may actually increase tension and effort, leading to increased stuttering. With time, continued exposure to difficult speaking experiences may crystallize into a negative self-concept and self-image. Many perceive stutterers as less intelligent due to their disfluency; however, as a group, individuals who stutter tend to be of above average intelligence. A person who stutters may project his or her attitudes onto others, believing that they think he or she is nervous or stupid. Such negative feelings and attitudes may need to be a major focus of a treatment program.

Many people who stutter report a high emotional cost, including jobs or promotions not received, as well as relationships broken or not pursued.

Fluency and disfluency

Linguistic tasks can invoke speech disfluency. People who stutter may experience varying disfluency." Tasks that trigger disfluency usually require a controlled-language processing, which involves linguistic planning. In stuttering, it is seen that many individuals do not demonstrate disfluencies when it comes to tasks that allow for automatic processing without substantial planning. For example, singing "Happy Birthday" or other relatively common, repeated linguistic discourses, could be fluid in people who stutter. Tasks like this reduce semantic, syntactic, and prosodic planning, whereas spontaneous, "controlled" speech or reading aloud requires thoughts to transform into linguistic material and thereafter syntax and prosody. Some researchers hypothesize that controlled-language activated circuitry consistently does not function properly in people who stutter, whereas people who do not stutter only sometimes display disfluent speech and abnormal circuitry.

Causes

No single, exclusive cause of developmental stuttering is known. A variety of hypotheses and theories suggests multiple factors contributing to stuttering. Among these is the strong evidence that stuttering has a genetic basis. Children who have first-degree relatives who stutter are three times as likely to develop a stutter. However, twin and adoption studies suggest that genetic factors interact with environmental factors for stuttering to occur, and many people who stutter have no family history of the disorder. There is evidence that stuttering is more common in children who also have concomitant speech, language, learning or motor difficulties. Robert West, a pioneer of genetic studies in stuttering, has suggested that the presence of stuttering is connected to the fact that articulated speech is the last major acquisition in human evolution.

Another view is that a stutter (stammer) is a complex tic. This view is held for the following reasons. It always arises from repetition of sounds or words. Young children like repetition and the more tense they are feeling, the more they like this outlet for their tension - an understandable and quite normal reaction. They are capable of repeating all types of behaviour. The more tension that is felt, the less one likes change. The more change, the greater can be the repetition. So, when a 3 year old finds he has a new baby brother or sister he may start repeating sounds. The repetitions can become conditioned and automatic and ensuing struggles against the repetitions result in prolongations and blocks in his speech. More boys stammer than girls, in the ratio of 3-4 boysÂ : 1 girl. This is because the male Hypothalamic-Pituitary-Adrenal (HPA) Axis is more active. Whilst they are pumping out more cortisol than females under the same provocation, they can be tense or anxious and become repetitive.

In a 2010 article, three genes were found to correlate with stuttering: GNPTAB, GNPTG, and NAGPA. Researchers estimated that alterations in these three genes were present in 9% of people who stutter who have a family history of stuttering.

For some people who stutter, congenital factors may play a role. These may include physical trauma at or around birth, learning disabilities, as well as cerebral palsy. In other people who stutter, there could be added impact due to stressful situations such as the birth of a sibling, moving, or a sudden growth in linguistic ability.

There is clear empirical evidence for structural and functional differences in the brains of people who stutter. Research is complicated somewhat by the possibility that such differences could be the consequences of stuttering rather than a cause, but recent research on older children confirms structural differences thereby giving strength to the argument that at least some of the differences are not a consequence of stuttering.

Auditory processing deficits have also been proposed as a cause of stuttering. Stuttering is less prevalent in deaf and hard-of-hearing individuals, and stuttering may be reduced when auditory feedback is altered, such as by masking, delayed auditory feedback (DAF), or frequency altered feedback. There is some evidence that the functional organization of the auditory cortex may be different in people who stutter.

There is evidence of differences in linguistic processing between people who stutter and people who do not stutter. Brain scans of adult people who stutter have found increased activation of the right hemisphere, which is associated with emotions, than in the left hemisphere, which is associated with speech. In addition, reduced activation in the left auditory cortex has been observed.

The capacities and demands model has been proposed to account for the heterogeneity of the disorder. In this approach, speech performance varies depending on the capacity that the individual has for producing fluent speech, and the demands placed upon the person by the speaking situation. Capacity for fluent speech may be affected by a predisposition to the disorder, auditory processing or motor speech deficits, and cognitive or affective issues. Demands may be increased by internal factors such as lack of confidence or self esteem or inadequate language skills or external factors such as peer pressure, time pressure, stressful speaking situations, insistence on perfect speech, and the like. In stuttering, the severity of the disorder is seen as likely to increase when demands placed on the person's speech and language system exceed their capacity to deal with these pressures. However, the precise nature of the capacity or incapacity has not been delineated.

Physiology

Though neuroimaging studies have not yet found specific neural correlates, there is much evidence that the brains of adults who stutter differ from the brains of adults who do not stutter. Several neuroimaging studies have emerged to identify areas associated with stuttering. In general, during stuttering, cerebral activities change dramatically in comparison to silent rest or fluent speech between people who stutter and people who do not stutter. There is evidence that people who stutter activate motor programs before the articulatory or linguistic processing is initiated. Brain imaging studies have primarily been focused on adults. However, the neurological abnormalities found in adults does not determine whether childhood stuttering caused these abnormalities or whether the abnormalities cause stuttering.

Studies utilizing positron emission tomography (PET) have found during tasks that invoke disfluent speech, people who stutter show hypoactivity in cortical areas associated with language processing, such as Broca's area, but hyperactivity in areas associated with motor function. One such study that evaluated the stutter period found that there was over activation in the cerebrum and cerebellum, and relative deactivation of the left hemisphere auditory areas and frontal temporal regions.

Functional magnetic resonance imaging (fMRI) has found abnormal activation in the right frontal operculum (RFO), which is an area associated with time-estimation tasks, occasionally incorporated in complex speech.

Researchers have explored temporal cortical activations by utilizing magnetoencephalography (MEG). In single-word-recognition tasks, people who do not stutter showed cortical activation first in occipital areas, then in left inferior-frontal regions such as Brocaâ€™s area, and finally, in motor and premotor cortices. The people who stutter also first had cortical activation in the occipital areas but the left inferior-frontal regions were activated only after the motor and premotor cortices were activated.

During speech production, people who stutter show overactivity in the anterior insula, cerebellum and bilateral midbrain. They show underactivity in the ventral premotor, Rolandic opercular and sensorimotor cortex bilaterally and Heschlâ€™s gyrus in the left hemisphere. Additionally, speech production in people who stutter yields underactivity in cortical motor and premotor areas.

Abnormal lateralization

Much evidence from neuroimaging techniques has supported the theory that the right hemisphere of people who stutter interferes with left-hemisphere speech production.

Adults who stutter have anatomical differences in gyri within the perisylvian frontotemporal areas. A large amount of white matter is found in the right hemisphere of the brain, including the region of the superior temporal gyrus. This was discovered using voxel-based morphometry (VBM). On the other hand, lesser amounts of white matter are found in the left inferior arcuate fasciculus connecting the temporal and frontal areas in stuttering adults.

Results have shown that there is less coordination between the speech motor and planning regions in the brain's left hemisphere of men and women who stutter, when compared to a non-stuttering control group. Anatomical connectivity of the speech motor and planning regions is less vigorous in adults who stutter, especially women. Men who stutter seem to have more right-sided motor connectivity. On the other hand, stuttering women have less connectivity with the right motor regions.

In non-stuttering, normal speech, PET scans show that both hemispheres are active but that the left hemisphere may be more active. By contrast, people who stutter yield more activity on the right hemisphere, suggesting that it might be interfering with left-hemisphere speech production. Another comparison of scans anterior forebrain regions are disproportionately active in stuttering subjects, while post-rolandic regions are relatively inactive.

Bilateral increases and unusual right-left asymmetry has been found in the planum temporale when comparing people who stutter and people who do not stutter. These studies have also found that there are anatomical differences in the Rolandic operculum and arcuate fasciculus.

Other anatomical differences

The corpus callosum transfers information between the left and right cerebral hemispheres. The corpus callosum, rostrum, and the anterior mid-body sections are larger in adults who stutter as compared to normally fluent adults. This difference may be due to unusual functions of brain organization in stuttering adults and may be a result of how the stuttering adults performed language-relevant tasks. Furthermore, previous research has found that adults who stutter show cerebral hemispheres that contain uncommon brain proportions and allocations of gray and white matter tissue.

Dopamine

Recent studies have found that adults who stutter have elevated levels of the neurotransmitter dopamine, and have thus found dopamine antagonists that reduce stuttering (see anti-stuttering medication below). Overactivity of the midbrain has been found at the level of the substantia nigra extended to the red nucleus and subthalamic nucleus, which all contribute to the production of dopamine. However, increased dopamine does not imply increased excitatory function since dopamine's effect can be both excitatory or inhibitory depending upon which dopamine receptors (labelled D1 - D5) have been stimulated.

Diagnosis

Some characteristics of stuttered speech are not as easy for listeners to detect. As a result, diagnosing stuttering requires the skills of a certified speech-language pathologist (SLP). Diagnosis of stuttering employs information both from direct observation of the individual and information about the individualâ€™s background, through a case history. Information from both sources should span multiple, various settings and times. The SLP may collect a case history on the individual through a detailed interview or conversation with the parents (if client is a child). They may also observe parent-child interactions and observe the speech patterns of the child's parents. The overall goal of assessment for the SLP will be (1) to determine whether a speech disfluency exists, and (2) assess if its severity warrants concern for further treatment.

During direct observation of the client, the SLP will observe various aspects of the individualâ€™s speech behaviors. In particular, the therapist might test for factors including the types of disfluencies present (using a test such as the Dysfluency Type Index (DTI)), their frequency and duration (number of iterations, percentage of syllables stuttered (%SS)), and speaking rate (syllables per minute (SPM), words per minute (WPM)). They may also test for naturalness and fluency in speaking (naturalness rating scale (NAT), test of childhood stuttering (TOCS)) and physical concomitants during speech (Rileyâ€™s Stuttering Severity Instrument Fourth Edition (SSI-4)). They might also employ a test to evaluate the severity of the stuttering and predictions for its course. One such test includes the stuttering prediction instrument for young children (SPI), which analyzes the childâ€™s case history, part-word repetitions and prolongations, and stuttering frequency in order to determine the severity of the disfluency and its prognosis for chronicity for the future.

Stuttering is a multifaceted, complex disorder that can impact an individualâ€™s life in a variety of ways. Children and adults are monitored and evaluated for evidence of possible social, psychological or emotional signs of stress related to their disorder. Some common assessments of this type measure factors including: anxiety (Endler multidimensional anxiety scales (EMAS)), attitudes (personal report of communication apprehension (PRCA)), perceptions of self (stutterersâ€™ self-rating of reactions to speech situations (SSRSS)), quality of life (overall assessment of the speakerâ€™s experience of stuttering (OASES)), behaviors (older adult self-report (OASR)), and mental health (composite international diagnostic interview (CIDI)).

The SLP will then attempt to combine the information garnered from the client's case study along with the information acquired from the assessments in order to make a final decision regarding the existence of a fluency disorder and determine the best course of treatment for the client.

Stuttering can also diagnosed per the DSM-5 diagnostic codes by clinical psychologists with adequate expertise. The most recent version of the DSM-5 describes this speech disorder as "Childhood-Onset Fluency Disorder (Stuttering)" for developmental stuttering, and "Adult-onset Fluency Disorder". However, the specific rationale for this change from the DSM-IV is ill-documented in the APA's published literature, and is felt by some to promote confusion between the very different terms "fluency" and "disfluency".

Classification

Developmental stuttering is stuttering that originates when a child is learning to speak and develops as the child matures into adulthood.

Other disorders with symptoms resembling stuttering include Asperger's syndrome, cluttering, Parkinson's speech, essential tremor, palilalia, spasmodic dysphonia, selective mutism, and social anxiety.

Developmental

Stuttering is typically a developmental disorder beginning in early childhood and continuing into adulthood in at least 20% of affected children. The mean onset of stuttering is 30 months. Although there is variability, early stuttering behaviours usually consist of word or syllable repetitions, while secondary behaviours such as tension, avoidance or escape behaviours are absent. Most young children are unaware of the interruptions in their speech. With young stutterers, disfluency may be episodic, and periods of stuttering are followed by periods of relatively decreased disfluency.

Though the rate of early recovery is very high, with time a young person who stutters may transition from easy, relaxed repetition to more tense and effortful stuttering, including blocks and prolongations. Some propose that parental reactions may affect the development of a chronic stutter. Recommendations to "slow down", "take a breath", "say it again", etc., may increase the childâ€™s anxiety and fear, leading to more difficulties with speaking and, in the "cycle of stuttering," to yet more fear, anxiety and expectation of stuttering. With time secondary stuttering, including escape behaviours such as eye blinking and lip movements, may be used, as well as fear and avoidance of sounds, words, people, or speaking situations. Eventually, many become fully aware of their disorder and begin to identify themselves as stutterers. With this may come deeper frustration, embarrassment and shame. Other, rarer patterns of stuttering development have been described, including sudden onset with the child being unable to speak, despite attempts to do so. The child usually is unable to utter the first sound of a sentence, and shows high levels of awareness and frustration. Another variety also begins suddenly with frequent word and phrase repetition, and does not include the development of secondary stuttering behaviours.

Stuttering can also have its roots in development. Many toddlers and preschool age children stutter as they are learning to talk, and although many parents worry about it, most of these children will outgrow the stuttering and will have normal speech as they get older. Since most of these children do not stutter as adults, this normal stage of speech development is usually referred to as pseudo-stuttering or as a normal disfluency. As children learn to talk, they may repeat certain sounds, stumble on or mispronounce words, hesitate between words, substitute sounds for each other, and be unable to express some sounds. Children with a normal disfluency usually have brief repetitions of certain sounds, syllables or short words, however, the stuttering usually comes and goes and is most noticeable when a child is excited, stressed or overly tired. Stuttering is also believed to be caused by neurophysiology. Neurogenic stuttering is a type of fluency disorder in which a person has difficulty in producing speech in a normal, smooth fashion. Individuals with fluency disorders may have speech that sounds fragmented or halting, with frequent interruptions and difficulty producing words without effort or struggle. Neurogenic stuttering typically appears following some sort of injury or disease to the central nervous system. Injuries to the brain and spinal cord, including cortex, subcortex, cerebellar, and even the neural pathway regions.

Acquired stuttering

In rare cases, stuttering may be acquired in adulthood as the result of a neurological event such as a head injury, tumour, stroke, or drug use. The stuttering has different characteristics from its developmental equivalent: it tends to be limited to part-word or sound repetitions, and is associated with a relative lack of anxiety and secondary stuttering behaviors. Techniques such as altered auditory feedback (see below), which may promote decreasing disfluency in people who stutter with the developmental condition, are not effective with the acquired type.

Psychogenic stuttering may also arise after a traumatic experience such as a grief, the breakup of a relationship or as the psychological reaction to physical trauma. Its symptoms tend to be homogeneous: the stuttering is of sudden onset and associated with a significant event, it is constant and uninfluenced by different speaking situations, and there is little awareness or concern shown by the speaker.

Treatment

Before treatment the assessment is needed. Some characteristics of stuttered speech are not as easy for listeners to detect. As a result, diagnosing stuttering requires the skills of a certified speech-language pathologist (SLP). While there is no complete cure for stuttering, several treatment options exist that help individuals to better control their speech. Many of the available treatments focus on learning strategies to minimize stuttering through speed reduction, breathing regulation, and gradual progression from single-syllable responses to longer words, and eventually more complex sentences. Furthermore, some stuttering therapies help to address the anxiety that is often elicited as a result of stuttering, and consequently exacerbates stuttering symptoms. This method of treatment is referred to as a comprehensive approach, in which the main emphasis of treatment is directed toward improving the speaker's attitudes toward communication and minimizing the negative impact stuttering can have on the speaker's life.

Speech language pathologists teach people who stutter to control and monitor the rate at which they speak. In addition, people may learn to start saying words in a slightly slower and less physically tense manner. They may also learn to control or monitor their breathing. When learning to control speech rate, people often begin by practising smooth, fluent speech at rates that are much slower than typical speech, using short phrases and sentences. Over time, people learn to produce smooth speech at faster rates, in longer sentences, and in more challenging situations until speech sounds both fluent and natural. When treating stuttering in children, some researchers recommend that an evaluation be conducted every three months in order to determine whether or not the selected treatment option is working effectively. "Follow-up" or "maintenance" sessions are often necessary after completion of formal intervention to prevent relapse.

Fluency shaping therapy

Fluency shaping therapy, also known as "speak more fluently", "prolonged speech", or "connected speech", trains people who stutter to speak less disfluently by controlling their breathing, phonation, and articulation (lips, jaw, and tongue). It is based on operant conditioning techniques.

People who stutter are trained to reduce their speaking rate by stretching vowels and consonants, and using other disfluency-reducing techniques such as continuous airflow and soft speech contacts. The result is very slow, monotonic, but fluent speech, used only in the speech clinic. After the person who stutters masters these skills, the speaking rate and intonation are increased gradually. This more normal-sounding, fluent speech is then transferred to daily life outside the speech clinic, though lack of speech naturalness at the end of treatment remains a frequent criticism. Fluency shaping approaches are often taught in intensive group therapy programs, which may take two to three weeks to complete, but more recently the Camperdown program, using a much shorter schedule, has been shown to be effective.

Modification therapy

The goal of stuttering modification therapy is not to eliminate stuttering but to modify it so that stuttering is easier and less effortful. The rationale is that since fear and anxiety causes increased stuttering, using easier stuttering and with less fear and avoidance, stuttering will decrease. The most widely known approach was published by Charles Van Riper in 1973 and is also known as block modification therapy. However, depending on the patient, speech therapy may be ineffective.

Electronic fluency device

Altered auditory feedback, so that people who stutter hear their voice differently, has been used for over 50 years in the treatment of stuttering. Altered auditory feedback effect can be produced by speaking in chorus with another person, by blocking out the person who stutters' voice while talking (masking), by delaying slightly the voice of the person who stutters (delayed auditory feedback) or by altering the frequency of the feedback (frequency altered feedback). Studies of these techniques have had mixed results, with some people who stutter showing substantial reductions in stuttering, while others improved only slightly or not at all. In a 2006 review of the efficacy of stuttering treatments, none of the studies on altered auditory feedback met the criteria for experimental quality, such as the presence of control groups.

Medications

The U.S. Food and Drug Administration (FDA) has not approved any drug for the direct treatment of stuttering. However, the effectiveness of pharmacological agents, such as benzodiazepines, anticonvulsants, antidepressants, antipsychotic and antihypertensive medications, and dopamine antagonists in the treatment of stuttering has been evaluated in studies involving both adults and children. A comprehensive review of pharmacological treatments of stuttering in 2006 concluded that few of the drug trials were methodologically sound. Of those that were, only one, not unflawed study, showed a reduction in the frequency of stuttering to less than 5% of words spoken. In addition, potentially serious side effects of pharmacological treatments were noted, such as weight gain, sexual dysfunctions and the potential for blood pressure increases. There is one new drug studied especially for stuttering named pagoclone, which was found to be well-tolerated "with only minor side-effects of headache and fatigue reported in a minority of those treated".

Support

With existing behavioral, prosthetic, and pharmaceutical treatments providing limited relief from the overt symptoms of stuttering, support groups and the self-help movement continue to gain popularity and support by professionals and people who stutter. Self-help groups provide people who stutter a shared forum within which they can access resources and support from others facing the same challenges of stuttering. One of the basic tenets behind the self-help movement is that since a cure does not exist, quality of life can be improved by not thinking about the stammer for prolonged periods. Psychoanalysis has claimed success in the treatment of stuttering. Hypnotherapy has also been explored as a management alternative. Support groups further focus on the fact that stuttering is not a physical impediment but a psychological one.

Psychological approach

Cognitive behavior therapy has been used to treat stuttering. Also sociological approaches has been explored regarding how social groups maintain stuttering through social norms.

Diaphragmatic breathing

Several treatment initiatives, for example the McGuire programme, and the Starfish Project advocate diaphragmatic breathing (or costal breathing) as a means by which stuttering can be controlled.

Prognosis

Among preschoolers, the prognosis for recovery is good. Based on research, about 65% of preschoolers who stutter recover spontaneously in the first two years of stuttering, and about 74% recover by their early teens. In particular, girls seem to recover well. For others, early intervention is effective in helping the child overcome disfluency.

Once stuttering has become established, and the child has developed secondary behaviors, the prognosis is more guarded, and only 18% of children who stutter after five years recover spontaneously. However, with treatment young children may be left with little evidence of stuttering.

With adult people who stutter, there is no known cure, though they may make partial recovery or even complete recovery with intervention. People who stutter often learn to stutter less severely, though others may make no progress with therapy.

Emotional sequelae associated with stuttering primarily relates to state-dependent anxiety related to the speech disorder itself. However, this is typically isolated to social contexts that require speaking, is not a trait anxiety, and this anxiety does not persist if stuttering remits spontaneously. Research attempting to correlate stuttering with generalized or state anxiety, personality profiles, trauma history, or decreased IQ have failed to find adequate empirical support for any of these claims.

Epidemiology

The lifetime prevalence, or the proportion of individuals expected to stutter at one time in their lives, is about 5%, and overall males are affected two to five times more often than females. However, there is not much information known about the underlying cause for such a skewed sex ratio. Most stuttering begins in early childhood, and studies suggest that 2.5% of children under the age of 5 stutter. As seen in children who have just begun stuttering, there is an equivalent number of boys and girls who stutter. Still, the sex ratio appears to widen as children grow: among preschoolers, boys who stutter outnumber girls who stutter by about a two to one ratio, or less. This ratio widens to three to one during first grade, and five to one during fifth grade, as girls have higher recovery rates. Due to high (approximately 65â€"75%) rates of early recovery, the overall prevalence of stuttering is generally considered to be approximately 1%.

Cross-cultural studies of stuttering prevalence were very active in early and mid-20th century, particularly under the influence of the works of Wendell Johnson, who claimed that the onset of stuttering was connected to the cultural expectations and the pressure put on young children by anxious parents. Johnson claimed there were cultures where stuttering, and even the word "stutterer", were absent (for example, among some tribes of American Indians). Later studies found that this claim was not supported by the facts, so the influence of cultural factors in stuttering research declined. It is generally accepted by contemporary scholars that stuttering is present in every culture and in every race, although the attitude towards the actual prevalence differs. Some believe stuttering occurs in all cultures and races at similar rates, about 1% of general population (and is about 5% among young children) all around the world. A US-based study indicated that there were no racial or ethnic differences in the incidence of stuttering in preschool children. At the same time, there are cross-cultural studies indicating that the difference between cultures may exist. For example, summarizing prevalence studies, E. Cooper and C. Cooper conclude: "On the basis of the data currently available, it appears the prevalence of fluency disorders varies among the cultures of the world, with some indications that the prevalence of fluency disorders labeled as stuttering is higher among black populations than white or Asian populations" (Cooper & Cooper, 1993:197). In his "Stuttering and its Treatment: Eleven lectures" Mark Onslow remarked that "one recent study with many participants (N=119,367) convincingly reported more stuttering among African Americans than other Americans. Why this could be the case is challenging to explain..."

Different regions of the world are researched very unevenly. The largest number of studies has been conducted in European countries and in North America, where the experts agree on the mean estimate to be about 1% of the general population (Bloodtein, 1995. A Handbook on Stuttering). African populations, particularly from West Africa, might have the highest stuttering prevalence in the worldâ€"reaching in some populations 5%, 6% and even over 9%. Many regions of the world are not researched sufficiently, and for some major regions there are no prevalence studies at all (for example, in China). Some claim the reason for this might be a lower incidence in the general population in China.

History

Because of the unusual-sounding speech that is produced and the behaviors and attitudes that accompany a stutter, it has long been a subject of scientific interest and speculation as well as discrimination and ridicule. People who stutter can be traced back centuries to the likes of Demosthenes, who tried to control his disfluency by speaking with pebbles in his mouth. The Talmud interprets Bible passages to indicate Moses was also a person who stuttered, and that placing a burning coal in his mouth had caused him to be "slow and hesitant of speech" (Exodus 4, v.10).

Galen's humoral theories were influential in Europe in the Middle Ages for centuries afterward. In this theory, stuttering was attributed to imbalances of the four bodily humorsâ€"yellow bile, blood, black bile, and phlegm. Hieronymus Mercurialis, writing in the sixteenth century, proposed methods to redress the imbalance including changes in diet, reduced libido (in men only), and purging. Believing that fear aggravated stuttering, he suggested techniques to overcome this. Humoral manipulation continued to be a dominant treatment for stuttering until the eighteenth century. Partly due to a perceived lack of intelligence because of his stutter, the man who became the Roman emperor Claudius was initially shunned from the public eye and excluded from public office.

In and around eighteenth and nineteenth century Europe, surgical interventions for stuttering were recommended, including cutting the tongue with scissors, removing a triangular wedge from the posterior tongue, and cutting nerves, or neck and lip muscles. Others recommended shortening the uvula or removing the tonsils. All were abandoned due to the high danger of bleeding to death and their failure to stop stuttering. Less drastically, Jean Marc Gaspard Itard placed a small forked golden plate under the tongue in order to support "weak" muscles.

Italian pathologist Giovanni Morgagni attributed stuttering to deviations in the hyoid bone, a conclusion he came to via autopsy. Blessed Notker of St. Gall (c. 840â€"912), called Balbulus ("The Stutterer") and described by his biographer as being "delicate of body but not of mind, stuttering of tongue but not of intellect, pushing boldly forward in things Divine," was invoked against stammering.

Famous Englishmen who stammered were King George VI and Prime Minister Winston Churchill, who led the UK through World War II. George VI went through years of speech therapy, most successfully under Australian speech therapist Lionel Logue, for his stammer. This is dealt with in the Academy Award-winning film The King's Speech (2010) in which Colin Firth plays George VI. The film is based on an original screenplay by David Seidler who also used to stutter as a child until age 16.

Churchill claimed, perhaps not directly discussing himself, that "[s]ometimes a slight and not unpleasing stammer or impediment has been of some assistance in securing the attention of the audience..." However, those who knew Churchill and commented on his stutter believed that it was or had been a significant problem for him. His secretary Phyllis Moir commented that "Winston Churchill was born and grew up with a stutter" in her 1941 book I was Winston Churchill's Private Secretary. She also noted about one incident "Itâ€™s s s simply s s splendid" he stuttered, as he always did when excited." Louis J. Alber, who helped to arrange a lecture tour of the United States, wrote in Volume 55 of The American Mercury (1942) that "Churchill struggled to express his feelings but his stutter caught him in the throat and his face turned purple" and that "born with a stutter and a lisp, both caused in large measure by a defect in his palate, Churchill was at first seriously hampered in his public speaking. It is characteristic of the manâ€™s perseverance that, despite his staggering handicap, he made himself one of the greatest orators of our time."

For centuries "cures" such as consistently drinking water from a snail shell for the rest of one's life, "hitting a stutterer in the face when the weather is cloudy", strengthening the tongue as a muscle, and various herbal remedies were used. Similarly, in the past people have subscribed to theories about the causes of stuttering which today are considered odd. Proposed causes of stuttering have included tickling an infant too much, eating improperly during breastfeeding, allowing an infant to look in the mirror, cutting a child's hair before the child spoke his or her first words, having too small a tongue, or the "work of the devil."

Some people who stutter, who are part of the disability rights movement, have begun to embrace their stuttering voices as an important part of their identity. In July 2015 the UK Ministry of Defence announced the launch of the Defence Stammering Network to support and champion the interests of British military personnel and MOD civil servants who stammer and to raise awareness of the condition.

Society and culture

Jazz and Eurodance musician Scatman John wrote the song "Scatman (Ski Ba Bop Ba Dop Bop)" to help children who stutter overcome adversity. Born John Paul Larkin, Scatman spoke with a stutter himself and won the American Speech-Language-Hearing Association's Annie Glenn Award for outstanding service to the stuttering community.

Fiction character Arkwright from the British sitcom Open All Hours stammered and much of the series' humour revolved around this. Recurring character Reginald Barclay from the Star Trek television franchise and the Emperor Claudius from the I,Â Claudius series by Robert Graves and acted by Derek Jacobi are portrayed as suffering from and overcoming their stuttering.

Looney Tunes character Porky Pig has a notable stutter, which features in one of the character's most well-known catchphrases ("Th-th-th-that's all, folks!"). The character's stuttering originated from the authentic stutter of the voice artist, Joe Dougherty. Dougherty's stutter caused recording sessions to take longer than otherwise necessary, causing Warner Bros. to replace Dougherty with Mel Blanc, who provided Porky's voice for the rest of his life.

The cartoon T.U.F.F. Puppy presents the character Keswick as stuttering.

In the 1996 film Primal Fear, Edward Norton plays Aaron, a shy altar boy with a stutter who is accused of murdering an influential bishop.

The 2015 Indian film Su.. Su... Sudhi Vathmeekam starring Jayasurya had portrayed the life of a real life person who overcomes the challenges faced in life due to stammering.

The 2016 Russian film Sheep & Wolves presents a wolf name Skinny with a stutter.
