Not only does hypertension affects the cellular structure and molecular composition of blood vessels (arteries, veins, capillaries), it also affects their ability to regulate vital functions that are essential for healthy brain function such as oxygen and glucose delivery, cerebral environment control via the blood-brain barrier, and trafficking of immune cells and metabolic by-products.[1] These hypertension induced effects eventually lead to white matter lesions, which is the pathological basis for hypertension induced cognitive impairment.[4] A National Institute on Aging (NIA) study that measured cognition 20 years after measuring blood pressure showed that there was a 9% increase in risk for cognitive decline for every 10mmHg increase in systolic blood pressure.[5] Additionally, the Atherosclerosis Risk in Communities cognitive study shows that those with prehypertension or high blood pressure performed lower on processing speed, short-term memory, and executive function tests.[5] Hypertension is also a prominent risk factor for 2 major brain diseases: stroke and dementia, and accounts for approximately 50% of deaths caused by stroke or heart disease according to the World Health Organization (WHO).
