Hypertension Could Alter Mood Regulation, Researchers Say

The latest genetic analysis involving over a thousand hypertension‑related markers suggests that persistent high blood pressure may compromise the tiny blood vessels that supply the brain’s emotional‑control centers. Damage to these micro‑vessels could impair the brain’s ability to modulate feelings of anxiety and sadness, potentially amplifying neurotic traits. Conversely, individuals already prone to chronic stress might experience rising blood pressure over time, creating a bidirectional relationship. Experts emphasize that the study’s results are preliminary and call for further investigations across diverse populations to confirm whether lowering blood pressure can also modify personality characteristics.
