Perspectives on the relation of blood pressure and cognition in the elderly

The relationship of blood pressure to cognition in the elderly is a poorly understood topic. Many questions exist such as does treatment of hypertension prevent cognitive decline, the optimal timing of intervention and selecting the appropriate agent. In this review we will explore recent epidemiologic data and clinical trials addressing hypertension and cognition, review pathophysiology of chronic hypertension and effects of brain function, discuss the timing of intervention and finally review opportunities for future research.
