Reports on findings from the carer component of the Gwynedd Dementia Study. It is based on carer interviews, using quantitative and qualitative data. It describes the carers, their perceptions of their dependents' problems, the common challenges they face, their experiences of formal and informal support and, with reference to the literature, identifies implications for policy and practice. Levels of formal service inputs were low, but most of the carers appeared to receive the services they needed. Problems are primarily associated with crisis support and long-term care is accepted reluctantly. Suggests that community care dementia specialists could play a supporting role for carers.
