Neural correlates of treatment response to ketamine for treatment-resistant depression: A systematic review of MRI-based studies.

Psychiatry Research October 1, 2024 Je-Yeon Yun, Yong‐Ku Kim 11 citations

Treatment-resistant depression (TRD) is defined as patients diagnosed with depression having a history of failure with different antidepressants with an adequate dosage and treatment duration. The NMDA receptor antagonist ketamine rapidly reduces depressive symptoms in TRD. We examined neural correlates of treatment response to ketamine in TRD through a systematic review of brain magnetic...

Joint-trajectories of clinical severity, social functioning and cannabis use in first-episode psychosis: A 5-year longitudinal study in 2 urban early intervention services.

Psychiatry Research September 1, 2024 Giuseppe D'Andrea, Clairélaine Ouellet-Plamondon, Marie Villeneuve et al.

Cannabis use is associated with increased psychosis incidence alongside worse outcomes. The role of cannabis may be complex, vary across patients and over time. Yet, few have examined the longer-term trajectories of cannabis use, symptoms and functioning and their inter-relationships. We conducted a 5-year longitudinal study to estimate joint-trajectories of clinical severity, social...

Psychiatry Research July 29, 2023 Mauro Pettorruso, Roberto Guidotti, Giacomo D’andrea et al. 56 citations

Treatment-resistant depression (TRD) represents a severe clinical condition with high social and economic costs. Esketamine Nasal Spray (ESK-NS) has recently been approved for TRD by EMA and FDA, but data about predictors of response are still lacking. Thus, a tool that can predict the individual patients' probability of response to ESK-NS is needed. This study investigates sociodemographic and...
