The current article reviews the literature pertaining to psychosis, aggress
ion and restlessness in dementia sufferers examining frequency, course and
associations as well as treatment considerations. All of these problems are
highly prevalent, with a high impact upon dementia sufferers and their car
ers. Although there has been an expansion in this literature over the last
few years there are still very few studies describing the natural course of
behavioural and psychological symptoms in dementia (BPSD) and a paucity of
data relating to non-Alzheimer dementias. Several large treatment studies
have recently been completed, but there are still very few double blind con
trolled trials focusing upon BPSD in particular respect to non-pharmacologi
cal interventions.
