Adolescents who use ayahuasca in a religious context show no significant differences in neuropsychological performance compared to matched controls. A battery of tests measuring speeded attention, visual search, sequencing, psychomotor speed, verbal and visual abilities, memory, and mental flexibility found no impairment among ayahuasca users. The groups were matched for sex, age, and education. Statistical comparisons using independent t-tests indicated no significant differences on any measure. The authors suggest further studies are needed to confirm these findings.
In Brazil's first clinical trial of MDMA-assisted psychotherapy for post-traumatic stress disorder (PTSD), three patients with PTSD from sexual abuse completed treatment. The protocol involved 15 weekly therapy sessions, with three sessions including orally administered MDMA combined with psychotherapy and music, spaced about a month apart. Two months after the final MDMA session, all three patients showed clinically significant improvement, with CAPS-4 scores dropping by more than 30% from baseline. Final scores were 61, 27, and 8, down from 90, 78, and 72. No serious adverse events occurred; common side effects were somatic pains and anguish. Secondary outcomes also improved. MDMA-assisted psychotherapy could become a viable PTSD treatment in Brazil.
