Adult hippocampal neurogenesis plays a critical role in a wide spectrum of
hippocampus-dependent functions. Brain pathologies that involve the hippocampus
like epilepsy, stroke, and traumatic brain injury, are commonly associated with
cognitive impairments and mood disorders. These insults can affect neural stem
cells and the subsequent neurogenic cascade in the hippocampus, resulting in the
induction of aberrant neurogenesis, which is thought to compromise hippocampal
network function, thereby hampering hippocampus-dependent behavior. We here
summarize recent preclinical literature on hippocampal insult-induced changes in
neurogenesis and based on that, we propose that normalizing aberrant neurogenesis
post-insult may help to prevent or rescue behavioral deficits which could help
develop novel therapeutic strategies.
