Does hypertension after age 65 years increase the risk of AD, vascular dementia, or cognitive decline in elderly individuals?
Hypertension in the elderly is not linked to Alzheimer's disease but may increase the risk of vascular dementia, particularly when comorbid with heart disease or diabetes.
Hypertension after age 65 years is not associated with AD and does not adversely affect memory, language, or general cognitive function. A history of hypertension may be an antecedent to VaD, particularly in the presence of heart disease or diabetes.
Posner et al. (Tue,) studied this question.
