22 The Effect of Ibogaine on Cognitive Functioning
Journal of the International Neuropsychological Society November 1, 2023 Kirsten Cherian, Afik Faerman, Lauren Anker et al.
A single ibogaine treatment was associated with improvements in processing speed, executive functions, verbal fluency, and verbal learning among U.S. Special Operations Veterans with histories of combat, blast exposure, and traumatic brain injury. Thirty participants completed neuropsychological testing before and after treatment, and 27 returned for one-month follow-up. Scores on the WAIS-IV Processing Speed Index, Delis-Kaplan Color Word test, verbal fluency, and Hopkins Verbal Learning Test improved significantly. No negative cognitive effects were observed up to one month post-treatment. The findings suggest ibogaine may have therapeutic potential for cognition after traumatic brain injury, though further research is needed.
