Autism spectrum disorder characteristics have not been evaluated in Cornelia de Lange and Cri du Chat syndromes using robust assessments. The Autism Diagnostic Observation Schedule and Social Communication Questionnaire were administered to 34 participants with Cornelia de Lange syndrome and a comparison group of 23 participants with Cri du Chat…

The prevalence of eating disorders among 311 adults with mental retardation living in the West Coast of Norway was investigated. Reports stemming from a questionnaire completed by health workers were the data source. Diagnostic criteria adapted for persons with mental retardation were used. The main finding was that 27% of cases showed indices of…

Akathisia, a state of uncontrollable motor restlessness, is a side effect of neuroleptic treatment. The prevalence rate of akathisia in 94 adults with mental retardation was estimated to be 5% in neuroleptic-free subjects, 17% in neuroleptic-maintenance subjects, and 25% in neuroleptic-reduction subjects. Akathisia was also related to dyskinesia…

Medicaid billing information was used to examine the administration of psychotropic medication to residents of community long-term care facilities providing mental retardation services. Results indicated 28.9 percent of such residents in Illinois received at least one psychotropic medication with little or no influence of demographic and facility…

Reports of injury/illness incidents involving 123 adults with developmental disabilities were studied to determine the incidence of pain insensitivity/indifference. A significantly elevated pain threshold was noted for 25% of subjects and was related to severity of mental retardation. Medical and rehabilitation implications in terms of risking…

Thirty-nine children (younger than 40 months) with developmental disabilities and identified as at risk for self-injurious behavior (SIB) were studied using video sampling, observation notes, parent reports, staff reports, and clinical records. Twenty-one children or 4.6 percent of the original group exhibited SIBs. Almost all children in the…

This study found a high incidence of nontraumatic fractures in adults with developmental disabilities living in a state-run facility, a 7.3% incidence among 391 adults. Factors associated with fractures included use of antiepileptic medication. Although bone mineral density (BMD) by heel ultrasound did not predict fracture, values were much lower…

This study of 12 residents of a treatment facility for individuals with mental retardation examined cycles in occurrences of self-injurious behavior (SIB) and aggression both within and across individuals. The study confirmed that such behavior tended to be rhythmical, with cycles of three-month and five-month periods consistently observed for…

The etiology of intellectual disability was studied both in incident (n = 9,432) and prevalent (n = 9,351) populations in a one-year birth cohort born in Northern Finland in 1985-1986. Data from multiple sources were used to follow the children until the age of 11.5 years. Of the incident cases (n = 119) with intellectual disabilities, 66.4% had…

Prevalence estimates often use U.S. Census Bureau estimates of the population as denominator data. Postcensal estimates are population estimates produced following a decennial census. Intercensal estimates are surrounded by 2 census years and supersede postcensal estimates. In this report we describe prevalence estimates in Atlanta for mental…

Musical aptitude and behavioral adjustment were assessed in 16 mentally retarded adults nominated as having special musical interests and/or skills. Evidence of difficulties in adjustment associated with musical skill or interest was mixed, though results suggested no pervasive maladjustment among those with exceptional skill combined with mental…

This longitudinal study with 117 adults with mental retardation found a considerably higher incidence (28%) of excessive cerumen (ear wax) and cerumen impaction with associated conductive hearing loss in this population than in the general adult population (2-6%). Moreover, a strong propensity for recurrent cerumen impaction was found in these…

Administrators of residential facilities for persons with mental retardation are urged to take a proactive stance in determining the prevalence of Human Immunodeficiency Virus (HIV). Administrators of one 345-bed intermediate care facility used a double blind seroprevalence study. No HIV infection was found in this group. (DB)

Neuroleptic-induced akathisia is a relatively common side effect of neuroleptic medication, characterized by a subjective sense of restlessness; the inability to sit still; and sometimes aggression, anxiety, sleep disturbance, and suicide. The importance of the diagnosis and treatment of neuroleptic-induced akathisia in individuals with mental…

Comparison of the production of repetitive speech during conversations in 30 people with either fragile X syndrome, autistic disorder, or mental retardation not caused by fragile X found repetitive speech more prevalent among those with fragile X. Results support the hypothesis that such speech dysfluency reflects the effects of physiological…
