Area of Science:

• Neuroscience
• Psychology
• Public Health

Background:

• High blood pressure is a known risk factor for cognitive decline.
• The role of social support satisfaction in this relationship is understudied, especially in Black Americans.
• Black Americans face disproportionately high rates of hypertension and cognitive decline.

Purpose of the Study:

• To investigate if high blood pressure predicts cognitive changes over three years.
• To determine if satisfaction with emotional or instrumental social support moderates this association.
• To understand protective factors for cognitive health in Black Americans with hypertension.

Main Methods:

• Study included 450 Black Americans (aged 48-95) from the Baltimore Study of Black Aging-Patterns of Cognitive Aging.
• Cognitive domains assessed: working memory, processing speed, verbal memory, vocabulary, and inductive reasoning.
• High blood pressure and social support satisfaction were self-reported; data analyzed using linear regression.

Main Results:

• No direct link was found between high blood pressure and cognitive changes over three years.
• Satisfaction with emotional support showed a marginal moderating effect.
• Higher emotional support satisfaction was linked to better working memory in individuals without high blood pressure.

Conclusions:

• Satisfaction with emotional support may mitigate adverse cognitive effects of high blood pressure.
• This highlights a modifiable factor for preserving cognitive health in Black Americans.
• Further research is needed to explore intervention strategies involving emotional support satisfaction.
