Hypertension and dementia: Does blood pressure control favorably affect cognition?

Dementia and aging are not synonymous. Dementia is a progressive deterioration in cognitive and social and/or occupational functions that can eventually impair a patient’s ability to live independently. Alzheimer’s disease is the most common form of dementia. It accounts for 50% to 70% of all patients with dementia. Vascular dementia, responsible for up to 15% of all diagnosed cases, is the second most common form of dementia. Hypertension remains a significant risk factor for vascular dementia.
