When systemic inflammation breaches the central nervous system, it diverts vital tryptophan away from serotonin and into quinolinic acid, a neurotoxin that scorches brain circuits. This metabolic hijacking reveals that treatment-resistant depression is often not a personal shortcoming, but an active inflammatory storm causing severe glutamate excitotoxicity.
Discover why standard antidepressants fail when immune alarms are blaring, how ketamine functions as an emergency circuit breaker to shield synapses from toxic overstimulation, and how inflammatory biomarkers like C-reactive protein are ushering in precision psychiatry. Tune in to learn how targeting the inflamed brain can finally extinguish the fire and restore lasting neural healing.
