Spotlight: Ketamine's Role in Neuroinflammation and Neuroprotection Across Neurological and Psychiatric Disorders: A Narrative Review (Silva, et al, 2025)

"Our findings indicate that ketamine reduces excitotoxicity and inflammation, which may contribute to neuroprotection in acute neurological injuries. These insights underscore ketamine's potential as an adjunctive neuroprotective agent, warranting further clinical investigation...

Ketamine’s Role in Neuroinflammation and Neuroprotection Across Neurological and Psychiatric Disorders: A Narrative Review - PubMed
Ketamine, a widely used anesthetic with emerging evidence suggesting neuroprotective and anti-inflammatory properties across various neurological disorders, is recognized for its NMDA receptor antagonism. It has been postulated to play a role in neuroprotection, due to its anti-inflammatory properti …

(2025):"we conducted a narrative review synthesizing current knowledge on ketamine's operating mechanisms, including its modulation of synaptic plasticity, excitotoxicity, and cytokine release, alongside its therapeutic applications in traumatic brain injury, neurodegenerative diseases, psychiatric disorders, and pain management."

"...evidence suggests that the use of serotonergic and non-serotonergic psychedelics (ketamine) for the treatment of SUD may provide advantages over traditional therapeutics, and these compounds may eventually become part of the next generation of treatments for SUD under specific circumstances."

"Serotonergic psychedelics & ketamine appear to share common cellular mechanisms. They both recruit glutamatergic neurons to stimulate BDNF-trKB signaling, promoting synaptogenesis via the mTOR pathway. These changes may explain their efficacy in depression, anxiety, PTSD, & addiction."
