Dynamic Substates of the Default Mode Network Are Associated with Mystical Experiences and Clinical Outcomes after Magnesium-Ibogaine Treatment in Veterans with Traumatic Brain Injury

medRxiv July 22, 2026 Kenneth Shinozuka, Clayton Olash, Tracy Han et al. preprint

Preliminary evidence suggests that the combination of magnesium and ibogaine, an atypical psychedelic, may be a promising treatment for post-traumatic stress disorder (PTSD), opioid use disorder, and traumatic brain injury (TBI). The "mystical" experience elicited by ibogaine, which is characterized by feelings of awe, selflessness, and transcendence, is correlated with improvements in PTSD...

Indication-stratified mortality risk of ibogaine treatment under contemporary safety protocols: a multisite analysis of 19,071 patients and updated systematic review of fatalities

Research Square June 17, 2026 Martijn Arns, Kenneth Shinozuka, Joseph P Barsuglia

Abstract Ibogaine has shown early therapeutic promise for substance use disorders (SUD) and post-traumatic stress disorder in veterans, but concerns about treatment-associated cardiac arrhythmia and death have constrained clinical development. Whether this risk is uniform across indications or concentrated in specific populations is unknown. We conducted a retrospective multisite study of...

Although a prior study demonstrated that ibogaine transiently alters electroencephalography (EEG) power in...
