Intensive control of hypertension and risk of Alzheimer's dementia in older adults with depression.

OBJECTIVES: Intensive control of hypertension has been reported to decrease risk of cognitive decline. However, the effect of this in older adults with hypertension and comorbid depression is not well understood. We aim to identify whether intensive control of systolic blood pressure (BP) is associated with reduced risk of Alzheimer's dementia (AD) in a clinical population. METHODS: Using data from the National Alzheimer's Coordinating Center, we conducted survival analyses in older adults with normal cognition at baseline and treated hypertension. We also examined those with comorbid depression, to determine if intensive control of systolic BP (
