The object of the study was to evaluate the association between cholesterol levels and the prevalence of dementia. At the start of the study a total of 1,051 individuals aged 65 years or over were assessed for dementia and again after three years.
The study found:
(a) After one year, individuals with dementia had significantly lower cholesterol levels and significantly lower levels of high-density lipoprotein (HDL) cholesterol compared with individuals without dementia.
(b) After three years, individuals newly diagnosed with dementia had significantly lower cholesterol levels and significantly lower levels of high-density lipoprotein (HDL) cholesterol compared with individuals without dementia.
The results of the study demonstrate that low cholesterol levels and low levels of HDL cholesterol are associated with higher rates of dementia.
