Mortality in elderly patients with organic brain disorder enrolled on the Salford Psychiatric Case Register.
The observed mortality of 397 elderly patients with organic brain disorder, recruited to the Salford Psychiatric Case Register between 1 January 1968 and 31 December 1975 and followed up by record linkage to 31 December 1985, was compared with expected mortality. The overall SMR was 1.91. SMRs were significantly raised for all age groups beyond 65 years, being highest in the younger age-bands and declining almost linearly with age. SMRs were elevated for both men and women, during all calendar periods, for incident and prevalent cases, and throughout the whole follow-up period, being highest in the first year. While social class variations may account for up to 9% of the excess deaths, marital status and ethnic differences had little effect.
