The association of elective mutism and mental retardation is noted. Two cases of elective mutism associated with mental retardation are presented. Both individuals had long-standing patterns of inhibition, shyness, and anxiety manifested by general refusal to talk outside the home, particularly at school. The importance of assessment of intellectual functioning and linguistic skills for the establishment of intervention priorities and clinical management is discussed. The possibility of the presence of mental retardation in individuals with elective mutism should be considered.

Elective mutism (EM) is not regarded as a separate diagnostic category in the ICD-9, but is included under the heading "313: Disturbance of emotions specific to childhood and adolescence." In the ICD-10 EM is acknowledged as a separate diagnosis defined as "a marked, emotionally determined lack of speech in certain situations in a child with a normal or near normal speech/language ability." The diagnosis excludes pervasive developmental disorder and specific developmental disorders of speech and language. Two patients referred for EM to a child and adolescent psychiatry outpatient clinic, showed specific developmental delays and assessment indicated slight mental retardation in one of them. The question arose regarding how extensively EM is reported in the literature as associated with developmental disorder/delay. A search was carried out in four data-bases where most references were listed under the keyword "mutism". This paper presents the two case studies, and the results of the literature inventory. It concludes that EM may be associated with developmental disorder/delay and suggests that this could be a predisposing factor for an emotionally determined lack of speech in certain situations.

A delay in speech development may be a symptom of many disorders, including mental retardation, hearing loss, an expressive language disorder, psychosocial deprivation, autism, elective mutism, receptive aphasia and cerebral palsy. Speech delay may be secondary to maturation delay or bilingualism. Being familiar with the factors to look for when taking the history and performing the physical examination allows physicians to make a prompt diagnosis. Timely detection and early intervention may mitigate the emotional, social and cognitive deficits of this disability and improve the outcome.
