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...

Increased cortical thickness and decreased brain age among special operations veterans with blast TBI after a magnesium-ibogaine protocol

iScience February 21, 2026 Andrew Geoly, John P. Coetzee, Derrick Matthew Buchanan et al.

= 22). Longitudinal analyses assessed cortical thickness, subcortical volume, and predicted brain age (pBA), estimated from T1 scans. pBA was significantly reduced at 1 month relative to baseline (-1.3 years). Cortical thickness analysis revealed post-treatment increases in 11 regions. Subcortical analyses revealed significant volumetric expansion in 8 regions. Magnesium-ibogaine therapy was...

Neural correlates of ibogaine: Evidence from functional neuroimaging of military veterans

Biological Psychiatry Cognitive Neuroscience and Neuroimaging February 1, 2026 Malvika Sridhar, Azeezat Azeez, Andrew Geoly et al.

BackgroundIbogaine was recently found to result in significant functional improvements in treating the sequelae of traumatic brain injury (TBI) among Special Operations Forces veterans (SOVs). In the current study, we used multimodal neuroimaging to elucidate the neural correlates of ibogaine in 30 male SOVs who received ibogaine treatment.MethodsArterial spin labeling and blood oxygen...

Is ibogaine treatment durable? 12-month follow-up of magnesium–ibogaine therapy (MISTIC) in Special Operations Veterans with traumatic brain injuries

Research Square December 17, 2025 Camarin E. Rolle, Nolan Williams, Afik Faerman et al.

Abstract Traumatic brain injury (TBI) can result in chronic functional disability and is associated with persistent psychiatric symptoms, including posttraumatic stress disorder (PTSD), depression, and anxiety. Ibogaine, an oneirogenic alkaloid with unique pharmacological properties, has shown initial promise as a potential treatment for TBI-related sequelae. We previously observed large...

Mystical experiences during magnesium-Ibogaine are associated with improvements in PTSD symptoms in veterans.

Journal of Affective Disorders November 18, 2025 Randi Brown, Jennifer I. Lissemore, Kenneth Shinozuka et al. 1 citation

Ibogaine is an atypical psychedelic that evokes unique subjective effects, including mystical experiences. Mystical experiences have shown a mediating effect on clinical improvements following treatment with several psychedelic substances; however, the relationship between mystical experiences and clinical outcomes following ibogaine remains unclear. We examined the association between mystical...
