Family caregivers of a community-dwelling demented relative experience significant burden in their caregiving role. In particular, behavioural disturbances are expected to be responsible for high caregiver distress and burden. Above, in approximately 80% of the cases, institutionalization of the demented patients with dementia occurs as a result of a burdened caregiver. Because of the impressive disruptive character of behavioural disturbances, most caregivers appeal for pharmacological intervention at a given moment, expecting instant suppression of the aberrant behaviour.
