A study of 502 individuals found that high blood pressure and increasing blood pressure during midlife are associated with reduced brain volume and white matter lesions in later life. However, there is no evidence that these associations are linked to cognitive decline or the build-up of beta-amyloid plaques.
Changes in blood pressure in early adulthood have been linked to markers of poorer brain health in later life, according to a UCL-led research study. Higher blood pressure at midlife and faster rises in blood pressure between ages 36 and 43 were associated with smaller brain volumes.
A study by UCSF researchers found that intensifying antihypertensives at hospital discharge may increase falls, fainting and acute kidney injury without long-term benefits. Patients who received intensified medications had a higher risk of readmission and medication-related serious adverse events within 30 days.
