Severe blood pressure fluctuations increase the risk of dementia. Caution!
감성아재권 2024. 2. 21. 05:38Research has shown that severe fluctuations in blood pressure can increase the risk of dementia. It seems like the medical field always only publishes research results that are of concern… This time, we are looking at the results of research on blood pressure fluctuations and dementia. Let’s find out together.

Research on blood pressure fluctuations and dementia among symptoms of high blood pressure
This study was conducted by Professor Daria Gutterridge's research team at the Cognitive Aging-Disability Neuroscience Laboratory (CAIN) at the University of South Australia, Australia, on 70 healthy elderly people (ages 60 to 80) without any signs of cognitive impairment or dementia.

- Cognitive function test
- Simultaneously measure 24-hour ambulatory blood pressure (daytime-night blood pressure)
- Simultaneously measure morning and evening blood pressure for 4 days
- Simultaneously evaluate cerebral artery stiffness using transcranial Doppler echocardiography (TDS)
- Severe blood pressure fluctuations increase the risk of dementia. Needs attention.
Research results on blood pressure fluctuations and dementia among symptoms of high blood pressure
- Even in elderly people without clinical symptoms of cognitive decline, there appears to be a relationship between blood pressure variability and cognitive function.
- When blood pressure variability over 4 days is large, executive function decreases. Executive functions are functions related to attention, concentration, thinking, and reasoning, and are essential cognitive functions in daily life.
- The risk of cerebral arteriosclerosis increases if the systolic blood pressure, the highest blood pressure among 24-hour ambulatory blood pressure, fluctuates significantly.
- The difference between daytime blood pressure, which rises during the day, and nighttime blood pressure, which falls at night, has no effect on cognitive function when considering other variables.
- When 24-hour ambulatory blood pressure is highly variable, attention and psychomotor speed (PS) decrease. Psychomotor speed is the speed at which thoughts move.
Conclusion
The research team explained that the overall results show that greater blood pressure variability increases the risk of cognitive decline and cerebral arteriosclerosis, regardless of average blood pressure.

We investigated the relationship between blood pressure fluctuations and dementia, one of the symptoms of high blood pressure. Given this relationship, I think I need to manage my blood pressure well. My worries have increased again…
