Dementia link to sudden low blood pressure and dizziness

Scientists say people who experience frequent drops in blood pressure or dizziness when suddenly standing up are at increased risk of dementia. They suggest that less blood reaches the brain during these moments, leading to brain cell damage over time. Dementia experts say this is a “robust study” and “plausible explanation” that needs further investigation. Scientists focused on transient periods of low blood pressure – also known as postural hypotension – which become more common in older age. These episodes can sometimes leave people feeling dizzy or give them “head rushes” when standing up suddenly. They found those who suffered repeated periods of low blood pressure on standing were more likely to develop dementia in the years that followed.
