Is there an increased relative risk of death in severe neurosis? 1,482 patients from three psychiatric units in different hospitals in Birmingham were followed-up after a mean of 10.9 years. 91 per cent of the sample were traced and 139 patients were found to have died; a highly significant increased mortality for both sexes for all causes of death. Although suicide and accidents contributed disproportionately, particularly in early follow-up, there was still a markedly increased mortality from the combined categories of nervous respiratory and cardiovascular disease, more evenly distributed in time.
