Exercise training is an important strategy to counteract cognitive and brain health decline during aging. Evidence from systematic reviews and meta-analyses supports the notion of beneficial effects of exercise in cognitively unimpaired and impaired older individuals. However, the effects are often modest, and likely influenced by moderators such as exercise training parameters, sample characteristics, outcome assessments, and control conditions. Here, we discuss evidence on the impact of exercise on cognitive and brain health outcomes in healthy aging and in individuals with or at risk for cognitive impairment and neurodegeneration. We also review neuroplastic adaptations in response to exercise and their potential neurobiological mechanisms. We conclude by highlighting goals for future studies, including addressing unexplored neurobiological mechanisms and the inclusion of under-represented populations.

Article Synopsis
  • A study evaluated the impacts of divalproex sodium on brain volumes in patients with mild to moderate Alzheimer’s disease using MRI scans over 24 months.
  • The results indicated that participants receiving divalproex experienced a significantly higher decline in hippocampal and brain volumes compared to those on placebo, along with a faster decline in cognitive function as measured by the Mini-Mental State Examination.
  • The findings suggest that divalproex treatment is linked to accelerated brain volume loss and potentially increased cognitive impairment, although the long-term effects remain unclear.

Article Synopsis
  • The study tested whether divalproex sodium (valproate) could prevent or delay agitation and psychosis in individuals with moderate Alzheimer's disease, enrolling 313 participants.
  • After two years of treatment, results showed no significant difference between the valproate and placebo groups regarding the time to development of agitation or psychosis.
  • Additionally, the valproate group experienced more side effects and showed greater reductions in brain volume, indicating potential adverse effects of the treatment.
