Rapid blood pressure fluctuations linked to early signs of brain degeneration in older adults

A new study by USC researchers reveals that short-term 'dynamic instability' in blood pressure is linked to loss of brain tissue and nerve cell injury in older adults. This phenomenon, where blood pressure fluctuates wildly from one heartbeat to the next, may be a key risk factor for brain shrinkage and neurodegeneration.
