Antipsychotic medication is frequently being prescribed to individuals with intellectual and developmental disabilities (IDD), often without a psychiatric diagnosis, a new study conducted by the Institute for Clinical Evaluative Sciences (ICES)and the Centre for Addiction and Mental Health (CAMH) has found. IDD includes diagnoses such as Down syndrome, fetal alcohol syndrome and autism.
The study, published today in The Canadian Journal of Psychiatry
, has made significant strides in filling the gap in research about prescribing practices of antipsychotic medication to adults with IDD. The six-year population-based study examined the health care data of 51,881 adults with IDD who were less than 65 years of age. Similar research has been conducted in other jurisdictions; however, this study is the first population-based study to investigate the use of antipsychotic medication in adults with IDD in Canada.
