Overview

Selective mutism is a social anxiety disorder in which a person who is normally capable of speech is unable to speak in given situations.

Causes

No single cause has been established, but there is some evidence that there is a hereditary component.

Differential Diagnosis

Autism spectrum disorder
Communication disorders

Language disorder
Speech sound disorder (previously phonological disorder)
Childhood-onset fluency disorder (stuttering)
Pragmatic (social) communication disorder

Intellectual disability
Neuro-developmental disorders
Psychotic disorders
Schizophrenia
Social anxiety disorder (social phobia)^[1]

Epidemiology and Demographics

Prevalence

The prevalence of selective mutism is 30-1,000 per 100,000 (0.03%-1%) of the overall population.^[1]

Risk Factors

Behavioral inhibition
Genetic predisposition
Negative affectivity (neuroticism)
Parental history of shyness
Social anxiety
Social isolation^[1]

Natural History, Complications, and Prognosis

Children (and adults) with the disorder are fully capable of speech and understanding language, but fail to speak in certain social situations when it is expected of them. They function normally in other areas of behavior and learning, though appear severely withdrawn and some are unable to participate in group activities due to their extreme anxiety. It is like an extreme form of shyness, but the intensity and duration distinguish it. As an example, a child may be completely silent at school, for years at a time, but speak quite freely or even excessively at home.

Diagnostic Criteria

DSM-V Diagnostic Criteria for Selective Mutism^[1]

“

A. Consistent failure to speak in specific social situations in which there is an expectation for speaking (e.g., at school) despite speaking in other situations.

AND

B. The disturbance interferes with educational or occupational achievement or with social communication.

AND

C. The duration of the disturbance is at least 1 month (not limited to the first month of school).

AND

D. The failure to speak is not attributable to a lack of knowledge of, or comfort with, the spoken language required in the social situation.

AND

E. The disturbance is not better explained by a communication disorder (e.g., childhood onset fluency disorder) and does not occur exclusively during the course of autism spectrum disorder, schizophrenia, or another psychotic disorder.

”

Symptoms

Selective mutism is usually characterised by the following:

Consistent failure to speak in specific social situations (in which there is an expectation for speaking, e.g., at school) despite speaking in other situations.
Interference with educational or occupational achievement or with social communication.
Disturbance lasting at least 1 month (not limited to the first month of school).
Failure to speak not due to a lack of knowledge of, or comfort with, the spoken language required by the social situation.
Lack of better cause explained by a Communication Disorder (e.g. stuttering) and disturbance lasting longer than a Pervasive Developmental Disorder, Schizophrenia, or other Psychotic Disorder.

Typical sufferers have some of the following traits when anxious, some of which are often perceived as rudeness:

Find it difficult to maintain eye contact.
Often don't smile and have blank expressions.
Move stiffly and awkwardly.
Find situations where talking is normally expected particularly hard to handle (answering school registers, saying hello, goodbye, thank you, etc.).
Tend to worry about things more than others.
Can be very sensitive to noise and crowds.
Find it difficult to talk about themselves or express their feelings.

Treatment

Contrary to popular belief, people suffering from selective mutism don't necessarily improve with age, or grow out of it. Consequently, treatment at an early age is important. If it is not addressed, selective mutism tends to be self-reinforcing: the expectation that one suffering from selective mutism will not speak causes those around them to stop trying to initiate verbal contact, thus making the prospect of talking seem increasingly difficult or foreign. In such a situation, a change of environment (such as changing schools) can decrease the severity of one's selective mutism by eliminating such expectations.

Psychological treatment has also been shown to help the counteract this condition, though treatment in teenage years is sometimes more difficult. Specific courses of treatment differ based on the subject, and must take factors such as age into account.

Attempts to force a child to talk are typically ineffective and often result in higher anxiety levels, consequently worsening the condition.

Some in the psychiatric community believe that anti-anxiety medications may be effective in extremely low dosages while higher doses may worsen the condition. Others in the field advocate that the side-effects of psychiatric medications- in any dose and on any child- are so dangerous that they negate any temporary benefits, preferring behavioral and psychological interventions.

Stimulus Fading

Stimulus fading is a common treatment for younger children suffering from selective mutism. This sliding-in technique consists of the subject being brought into a controlled environment with someone who they are at ease with and can communicate with. Gradually, another person is introduced into the situation, often in several distinct stages. This process can be relatively long as the first few people are slid (or faded) into the environment and the conversation.

Desensitization

The subject is prompted to communicate via indirect means in order to prepare them mentally for direct communication. Methods of indirect communication include email, phone, voice recordings, and conversations on the internet.

Medical Therapy

Some practitioners advocate the use of antidepressants such as fluoxetine (prozac) as treatment for children with selective mutism. While many in the medical community believe that psychiatric medications can decrease anxiety levels enough to allow patients with selective mutism to communicate, others (see articles on Peter Breggin and David Healy (psychiatrist)) stringently decry the use of psychiatric medications on children. These practitioners and activists note the lack of medical evidence that behavioral disorders have genetic bases. The denunciation of psychotropic intervention on children with behavioral anxiety disorders intensified as lawsuits against several drug companies exposed previously unseen internal research documents linking fluoxetine and other SSRI antidepressants with increased risk of suicide, psychosis and damage to areas of the brain which could affect language production and normal social development.

+Selective mutism is a [[social anxiety]] disorder in which a person who is normally capable of [[Speech communication|speech]] is unable to speak in given situations.
-==Description==
-In the [[Diagnostic and Statistical Manual of Mental Disorders]] selective mutism is described as a rare [[psychology|psychological]] disorder in children. Children (and adults) with the disorder are fully capable of speech and understanding language, but fail to speak in certain social situations when it is expected of them. They function normally in other areas of behavior and learning, though appear severely withdrawn and some are unable to participate in group activities due to their extreme anxiety. It is like an extreme form of [[shyness]], but the intensity and duration distinguish it. As an example, a child may be completely silent at school, for years at a time, but speak quite freely or even excessively at home.
-Particularly in young children, selective mutism can sometimes be confused with an [[Autistic spectrum|autism spectrum disorder]], especially if the child acts particularly withdrawn around his or her diagnostician. Unfortunately, this can lead to incorrect treatment.
-Selective mutism is usually characterised by the following:
-*Consistent failure to speak in specific social situations (in which there is an expectation for speaking, e.g., at school) despite speaking in other situations.
-*The disturbance interferes with educational or occupational achievement or with social communication.
-*The duration of the disturbance is at least 1 month (not limited to the first month of school).
-*The failure to speak is not due to a lack of knowledge of, or comfort with, the spoken language required in the social situation.
-*The disturbance is not better accounted for by a Communication Disorder (e.g., Stuttering) and does not occur exclusively during the course of a Pervasive Developmental Disorder, Schizophrenia, or other Psychotic Disorder.
-The former name '''elective mutism''' indicates a widespread ''misconception'' even among psychologists that selective mute people choose to be silent in certain situations, while the truth is that they are forced by their extreme anxiety to remain silent; despite their will to speak, they just cannot make any voice. To reflect the involuntary nature of this disorder, its name had been changed to ''selective mutism'' in [[1994]]. However, misconceptions still prevail; for instance, the [[ABC News]] erroneously attributed the cause of selective mutism to trauma and described it as willful in a report dated [[May 26]], [[2005]].<ref>http://abcnews.go.com/Primetime/Health/story?id=794677&page=1</ref>
-The [[incidence (epidemiology)|incidence]] of selective mutism is not certain. Due to the poor understanding of the general public on this condition, many cases are undiagnosed. Based on the number of reported cases, the figure is commonly estimated to be 1 in 1000. However, in a 2002 study in ''The Journal of the American Academy of Child and Adolescent Psychiatry'', the figure has increased to 7 in 1000.
