Ask your doctor if this paper tells enough about how to make sure new neurons survive and migrate to damaged areas.

Vukovic et al. took an innovative approach to determine that
microglia play a significant role in the neurogenesis that occurs in the
hippocampus following physical exercise. They further demonstrated that
signaling through the fractalkine ligand–receptor (CX3CL1–CX3CR1)
pathway is a key mechanism through which microglia confer these
neuroprotective effects. When either CX3CL1 or CX3CR1 are reduced or
dysregulated, neural precursor cell activation is reduced. Physical
exercise was shown to be a robust intervention to elevate CX3CL1 levels
in the hippocampus of both adult and aged mice. Activated microglia in
aged subjects is associated with a neuroinflammatory phenotype, and when
they are depleted from neurosphere cultures, neurogenesis is robustly
enhanced, suggesting that interventions that reduce microglial
activation in aged subjects are of upmost benefit for the sake of
preserving critical hippocampal functions such as learning and memory.
