Psilocybin for the Treatment of Migraine Headache
Psilocybin for the Treatment of Migraine Headache
The purpose of this study is to investigate the effects of oral psilocybin in migraine
 headache. Subjects will each receive a dose of placebo and a dose of psilocybin approximately
 14 days apart. Subjects will be randomized to the order of treatment and they will be
 randomized to receive either low or high dose psilocybin. Subjects will maintain a headache
 diary prior to, during, and after the treatments in order to document headache frequency and
 intensity, as well as associated symptoms. This preliminary study will inform on the basic
 effects of psilocybin in migraine headache and inform on the design of larger, more
 definitive studies.
