Ketamine boosts neuroplasticity through microglia in female brains - News-Medical

Microglia facilitate increased neuroplasticity in female brains after exposure to ketamine, according to findings from News-Medical and Medical Xpress. This physiological response involves the active reshaping of neural networks, distinguishing the recovery process from that observed in male brains. The mechanism appears to directly influence how neural connections reorganize during the post-anesthesia phase.

Technology Networks and Discover Magazine emphasize that while ketamine remains a standard tool for emergency anesthesia, its systemic effects are not uniform across biological sexes. The focus rests on the unique pathways triggered in females, which contribute to distinct patterns of brain activity upon regaining consciousness. Coverage does not yet specify whether these microglia-led neuroplastic changes correlate with long-term cognitive differences or variations in clinical outcomes.

Data regarding the precise duration of these effects or potential implications for personalized anesthetic protocols remains limited. Whether similar mechanisms are triggered in male subjects through alternative pathways is not established by existing reports.
