Epidemiology

Several studies in a range of settings have suggested that DLB accounts for just under 20 per cent of all cases of dementia referred for neuropathological autopsy/3,4,,8) The male-to-female ratio in these autopsy series is 1.5:1, but it is unclear to what extent this represents increased male susceptibility or reduced survival. Age at onset ranges from 50 to 83 years and an age at death of between 68 and 92 years. (22> In all, 26 per cent of clinical referrals for dementia to an old age psychiatry service(23) and 24 per cent of demented day-hospital attenders met the clinical criteria for DLB.

Epidemiological surveys using memory-based screening instruments are likely to miss early DLB cases in whom memory function is relatively intact.
