Effects of a Sigle Dose of Ayahuasca in Patients With Psychogenic Non-epileptic Seizures: an Open Label Clinical Trial

Open label intervention with a single dose of ayahuasca in patients with psychogenic non-epileptic seizures (PNES)

Inclusion: Patients aged 18 to 60 with documented PNES (confirmed via VEEG), without a diagnosis of comorbid epilepsy, and currently receiving follow-up care at outpatient clinics. To enroll in the study, patients must undergo a gradual reduction and discontinuation of any psychotropic medications (antidepressants, antipsychotics, benzodiazepines, or mood stabilizers/anticonvulsants) they are currently taking, in order to avoid drug interactions with-or influence on-the effects of ayahuasca.

Exclusion: Patients who have not experienced psychogenic seizures in the last 3 months; patients diagnosed with epilepsy; patients who refuse to reduce or discontinue their current psychotropic medications; patients with a history of prior ayahuasca use; patients with a history of substance use disorder; patients who refuse to sign the Informed Consent Form; patients with schizophrenia or other psychotic disorders and/or impaired reality testing; and pregnant or breastfeeding women.
