  1. The Botany survey : a longitudinal study of depression and cognitive impairment in an elderly population.

    Article - En anglais

    An 8-year-long longitudinal study of elderly people in Botany (Sydney) has provided data on the prevalence, incidence and outcome of cognitive impairment and depression in this population.

    In 1985, a random sample of 146 persons aged 65 years or more, living in their own Lomes, were assessed using the Brief Assessment Schedule, depression ratings and cognitive tests.

    Follow-up interviews were conducted afeter 2,4,6 and 8 years. data from separate hostel and nursing home studies were used when estimating prevalence rates.

    The estimated prevalence and annual incidence of definite dementia in Botany were, respectively, 14% (3.5% severe) and 2.5%. Among elderly people living at home the prevalence of definite dementia was 11% ; 23% of our community sample suffered dementia during the 8 years.

    The prevalence and minimum annual incidence of depressive disorders were, respectively, 12.5% and 2.0%. Among those living at home the prevalence was 12.3%. Dementia was associated with a high mortality rate, but the apparently increased mortality of depressed subjects did not reach significance, probably because numbers were relatively small ; a high proportion of the deceased had comorbid cognitive impairment.

    Some depressions eventually remitted.
