Ketamine and Depression

A fascinating exploration reveals that the optimal dose of ketamine for treating depression often coincides with the onset of dissociative symptoms. Research indicates that patients with synaptic deficits experience significant increases in synaptic density alongside their dissociative experiences, suggesting a potential marker for effective treatment. However, for those without synaptic deficits, dissociation does not correlate with clinical improvement, highlighting the complexity of ketamine's effects in different patient populations.
