"Exercise: The Key to Boosting Brain Health and Preventing Disease"

Exercise can directly improve brain health by promoting hippocampal neuronal development, with astrocytes playing a key role in mediating the effects. Chemical signals released by contracting muscles promote neuronal development in the brain, which could lead to exercise-based treatments for cognitive disorders such as Alzheimer’s disease. Understanding the chemical pathway between muscle contraction and the growth and regulation of hippocampal neurons is just the first step in understanding how exercise helps improve brain health.
