Abstract
Objective: Recent studies suggest that psychosocial factors can have an impact on brain health. Yet, it is unclear whether psychosocial stress affects aging of the brain. The aim of the study was to investigate the association between psychosocial stress and brain aging.
Methods: Data from the German population-based cohort Study of Health in Pomerania (N=991; age range 20-78 years) were used to calculate a total psychosocial stress score by combining subscores from five domains: stress related to the living situation, the occupational situation, the social situation, danger experiences, and emotions. Associations with brain aging, indicated by an MRI-derived score quantifying age-related brain atrophy, were estimated by using regression models adjusted for age, gender, education, diabetes, problematic alcohol consumption, smoking, and hypertension.
Results: The relative risk ratio for advanced brain aging was 1.21 (95% CI=1.04-1.41) for stress related to emotions in fully adjusted models. The interactions between stress related to emotions and mental health symptoms were also significantly associated with advanced brain aging. The association between higher total psychosocial stress and brain aging was not statistically significant.
Conclusions: These findings highlight that high stress related to emotions is associated with advanced brain aging. To protect brain health in older age, more research is needed to explore the role of emotional distress.
期刊介绍：
As the official Journal of the American Neuropsychiatric Association, the premier North American organization of clinicians, scientists, and educators specializing in behavioral neurology & neuropsychiatry, neuropsychology, and the clinical neurosciences, the Journal of Neuropsychiatry and Clinical Neurosciences (JNCN) aims to publish works that advance the science of brain-behavior relationships, the care of persons and families affected by neurodevelopmental, acquired neurological, and neurodegenerative conditions, and education and training in behavioral neurology & neuropsychiatry. JNCN publishes peer-reviewed articles on the cognitive, emotional, and behavioral manifestations of neurological conditions, the structural and functional neuroanatomy of idiopathic psychiatric disorders, and the clinical and educational applications and public health implications of scientific advances in these areas. The Journal features systematic reviews and meta-analyses, narrative reviews, original research articles, scholarly considerations of treatment and educational challenges in behavioral neurology & neuropsychiatry, analyses and commentaries on advances and emerging trends in the field, international perspectives on neuropsychiatry, opinions and introspections, case reports that inform on the structural and functional bases of neuropsychiatric conditions, and classic pieces from the field’s rich history.
