Depression, post-traumatic stress disorder, suicidal ideation and ketamine: a case report

Ketamine infusions resulted in significant and sustained symptomatic improvement in both cases, accompanied by distinct electrophysiological changes indicative of altered brain function. These findings highlight the potential of ketamine as an alternative treatment for refractory conditions, such as major depressive disorder and posttraumatic stress disorder, offering relief and functional recovery for certain patients. Further research is warranted to elucidate the underlying mechanisms and optimize treatment protocols.
