Objectives. Verbal and physical aggression is a common problem in people with dementia. The aim of the study was to find out whether there is a relationship between dementing process etiology on the one hand, and the intensity of aggression (physical and verbal) and agitation on the other.
Methods. Participants in the study were 39 nursing home residents diagnosed with Alzheimer 's dementia (n = 24) or vascular dementia (n = 15) by the ICD-10 criteria. They were assessed for aggressive and impulsive behaviours using The Cohen-Mansfield Agitation Inventory (CMAI).
Results. The two groups (Alzheimer's disease and vascular dementia) differed in their aggressive behaviour intensity. Moreover, the association of age and cognitive impairment with aggression was confirmed.
Conclusion. The findings may have important implications for caregivers of demented nursing home residents.
