Drug burden index of people ageing with intellectual disability and cognitive complaints attending a specialist memory service

Medications with sedative or anticholinergic properties should be prescribed with caution in those with cognitive complaints. This is particularly relevant in people ageing with an intellectual disability (ID). Higher drug burden index (DBI) scores are associated with increased frailty and falls and reduced quality of life in older people and increased risk of adverse effects (daytime somnolence, constipation) in those with ID. While previous studies have shown that the ID population has higher rates of drug burden and a higher propensity to be prescribed an antipsychotic than the general population, the degree of burden has not been assessed specifically in those with ID and cognitive complaints.
