Lifting Weights to Lift Cognition: Resistance Training Shows Promise for Vascular Dementia
A new 12-month randomized clinical trial published in Alzheimer’s & Dementia provides evidence that progressive resistance training (PRT) can improve cognitive function in individuals with subcortical vascular cognitive impairment (SVCI), a form of dementia linked to cerebral small vessel disease. The study compared PRT to balance and tone exercises in 91 participants with mild cognitive impairment. Results showed that the PRT group experienced a statistically significant improvement in scores on the Alzheimer’s Disease Assessment Scale Cognitive Plus (ADAS-Cog-Plus) at the 12-month mark. Notably, this cognitive benefit was driven primarily by a significant effect observed in female participants. The intervention also led to a reduction in the inflammatory marker C-reactive protein, suggesting a potential biological mechanism for the observed cognitive gains.
Study Significance: This research directly addresses a gap in non-pharmacological interventions for vascular cognitive impairment, a major contributor to dementia worldwide. For clinicians and researchers focused on neurodegeneration and cognitive disorders, these findings underscore the potential of targeted exercise regimens as a complementary therapeutic strategy. The observed sex-specific response highlights the importance of personalized medicine approaches in neurology and warrants further investigation into the underlying neurobiological and hormonal factors.
