Behavoural symptoms in Alzhemier's disease: validity Of targets and present treatments

摘要

Behavioural symptoms occur in at least 50/100 of out- patients treated at a dementia clinic and their frequency may be even higher in nursing homes [1]. Physical aggression and delusions, wandering, agitation, sleep problems and anxiety are among the most important problems. They can result in emotional suffering for patients and caregivers, excess disability and mortality, premature institutionalization, and increased financial costs [2].
