Eight-month intensive meditation-based intervention improves refractory hallucinations and delusions and quality of life in male inpatients with schizophrenia: a randomized controlled trial.

Psychiatry and clinical neurosciences April 1, 2024 Ting Xue, Jialing Sheng, Hui Gao et al. 5 citations

An 8-month daily guided intensive meditation-based intervention (iMI) added to a general rehabilitation program reduced persistent hallucinations and delusions and improved health-related quality of life in male inpatients with treatment-refractory schizophrenia. In a randomized trial of 64 participants, those receiving iMI showed significantly greater reductions in Positive and Negative Syndrome Scale total scores, positive symptoms, and hallucination/delusion items at both 3 and 8 months compared with rehabilitation alone. Treatment response rates (at least 25% reduction) for these measures were higher in the iMI group at 8 months. The iMI group also reported better physical activity and mindfulness skills. Longer iMI duration produced stronger benefits.

Comparison of the Antianhedonic Effects of Repeated-dose Intravenous Ketamine in Older and Younger Adults with Major Depressive Episode.

Current neuropharmacology January 1, 2025 Wei Zheng, Limei Gu, Jianqiang Tan et al. 1 citation

Repeated intravenous ketamine infusions rapidly reduce anhedonia in both younger and older adults with major depressive episodes, but older patients show a weaker response. In a study of 135 patients (116 younger, 19 older) receiving six ketamine infusions over 12 days, anhedonia scores dropped significantly in both age groups within 4 hours of the first infusion, with effects maintained throughout treatment. By day 26, younger patients had lower anhedonia scores than older patients. The antianhedonic response rate was 51.7% in younger patients versus 31.6% in older patients, and remission occurred in 24.1% of younger patients but none of the older patients.
