Abstract

Objective: To estimate the prevalence of anxiety disorders and to explore several potential aetiological factors. Method: Ninety two consecutive patients assessed at a day hospital for patients with probable dementia were interviewed using the CAMDEX schedule. Fifty eight patients gave a sufficiently reliable interview and had a first degree relative in close contact as an informant and were hence included in the study group. The prevalence of RDC generalised anxiety disorder in this group was determined. Type of dementia, severity of dementia and insight were explored as possible aetiological factors. Results: The prevalence of RDC generalised anxiety disorder was 31%. Fifty percent of these patients suffered from anxiety symptoms in the context of RDC major depression. Anxiety disorders were most common in those with mild dementia and in those who retained insight, both showing a trend towards a significant association with anxiety. Conclusions: Anxiety disorders are very common in dementia sufferers particularly in those with mild dementia. Further research is needed in this area, particularly with respect to treatment.
