Anger and aggression may increase the risk of cerebrovascular disease. This study found a correlation between personality traits and the severity of carotid atherosclerosis, suggesting potential links to stroke risk.

Area of Science:

  • Neuroscience
  • Cardiology
  • Psychology

Background:

  • Metabolic and psychosocial factors are known coronary risk factors.
  • The relationship between personality and cerebrovascular disease remains understudied.

Purpose of the Study:

  • To investigate the association between anger/aggression and carotid atherosclerosis severity.
  • To determine if personality traits are risk factors for cerebrovascular disease.

Main Methods:

  • Cornell Medical Index, Rosenzweig Picture Frustration Study, and Yatabe-Guilford Personality Test assessed anger and aggression.
  • High-resolution B-mode ultrasonography measured carotid atherosclerosis severity (plaque score).
  • 34 patients with atherosclerosis or risk factors were evaluated.

Main Results:

  • A significant positive correlation was found between plaque score and anger (r = .65, P < .01).
  • A significant positive correlation was observed between plaque score and "extrapersistive" aggression (r = .50, P < .01).
  • Multivariate analysis confirmed associations between plaque score and age, hypercholesterolemia, and anger.

Conclusions:

  • Anger and potentially aggression may serve as risk factors for cerebrovascular disease.
  • Personality traits warrant further investigation in the context of cerebrovascular health.
