Abstract:Given medical and social advances, the life expectancy of individuals with intellectual disability (ID) has increased dramatically, leading to a generation of older individuals with such disabilities. This review focuses on the pharmacological treatment of behavioral and psychiatric symptoms and disorders in older persons with ID. Older adults with ID often present with medical co-morbidities and mental health issues. Medication management of behavioral and psychiatric problems is complicated by a higher risk for adverse events, lack of decision-making capacity, and complex care networks. Some studies have shown that persons with ID and co-morbid mental disorders are undertreated in comparison to individuals with similar disorders in the general population, resulting in poorer outcomes.However, older adults with ID are also at risk of polypharmacy and older age is a risk factor for development of side-effects. A general principle is that medication treatment for psychiatric disorders in older persons with ID should be started at low dosages and be increased cautiously while monitoring response and side-effects. The use of psychotropic drugs for older persons with ID and behavioral problems remains controversial, particularly in those with dementia.
Key points:• The growing population of older persons with ID has an increased risk for aging related health issues such as dementia, on a background of lifelong disabilities and physical health and psychiatric co-morbidities.
Management of psychiatric symptoms in older persons with ID• Medication management of behavioral and psychiatric problems may be complicated by a higher risk for adverse events, lack of decision-making capacity, and complex care networks.• Medication management of specific conditions is however beneficial, but in general, medication should be started at low doses, with careful titration against response, and regular monitoring for side-effects.
