Abstract

Objectives: To identify the number of cases, and hence the prevalence of, early onset dementia within a defined catchment area in Dublin. To identify the associated clinical characteristics of those identified, and to measure service use and carer burden.

Method: A comprehensive case finding study was carried out, and all those identified were contacted and sufferers and carers were interviewed using both standardised and semi-structured questionnaires.

Results: Twelve cases were identified, yielding a prevalence rate of 45/100,000 in the 45-64 year age group. Sufferers exhibited a high level of cognitive impairment and associated psychiatric and behavioural symptoms, and carers exhibited a high level of stress, especially those still actively caring. Service provision for this group was patchy and did not tally with their level of dependency.

Conclusions: Recommendations are made for appropriate provision of services for dementia sufferers, regardless of age.
