Annotation	Few studies have reported age-related rates for the main types of dementia in older people. In this study, age-specific incidence rates of undifferentiated dementias, Alzheimer's disease (AD) and vascular dementia were assessed. In addition, the study examined whether gender is a risk factor. A total of 5222 people aged 65 years and over in Liverpool were interviewed using the Geriatric Mental Health State/History and Aetiology Schedule. The AGECAT package was used to identify cases at three interviewing waves at two-year intervals. Findings revealed that incidence rates of the dementias increased with age. Age patterns were similar between AD and vascular dementia. Gender appeared to be influential in AD.The study calculated that in England and Wales, 39 437 new cases of AD, 20 153 of vascular dementia and 155 169 of undifferentiated dementia can be expected each year.
