Magnesium-ibogaine therapy effects on cortical oscillations and neural complexity in veterans with traumatic brain injury

This analysis of an open-label observational study (n=30) found that magnesium-ibogaine therapy in combat veterans with traumatic brain injury (TBI) led to slower brain wave patterns and reduced neural complexity on EEG, which correlated with improvements in PTSD, anxiety, and cognitive function at one-month follow-up.

Magnesium-ibogaine therapy in veterans with traumatic brain injuries

This observational study (n=30) evaluates ibogaine (up to 980mg/70kg) in combination with magnesium (1-2 hours before and 12 hours later) in male Special Operations Forces veterans with predominantly mild traumatic brain injury (mTBI). The study assessed changes in disability, PTSD, depression, and anxiety immediately and one month after treatment using various scales. Results show significant improvements in functioning and psychological symptoms with no serious adverse events.
