I previously reported (O'Shea, 1989, 1992) on the experience of national voluntary Huntington's disease (HD) and Alzheimer's disease (AD) organisations. This series of enquiries stemmed from an observation of Black (1988) that the medical profession in general offered little support to voluntary groups, a statement which has been largely supported for both HD and AD organisations in the first two parts of this trilogy. This final paper examines the experiences and attitudes of (mostly national) schizophrenia organisations.
