Antidepressant use in adults with intellectual disability

Abstract

Aims and method: To study the use of antidepressants in adults with intellectual disability, focusing on medication type, indication, retention and clinical outcome. Case notes of all service users in a learning disability service were hand-searched to identify antidepressant usage, and those who had been treated with antidepressants and in whom at least 1 year of follow-up was possible were included in the study. Results: A total of 241 treatment episodes were identified. The rates of positive outcome in terms of clinical improvement at 6 weeks, 6 months and 12 months were 49.4%, 48.1% and 49% respectively, and only 29 (12%) episodes of side-effects had been noted. Clinical implications: Antidepressants are commonly prescribed in adults with intellectual disability. Approximately half did well in terms of clinical improvement.
