Secondary Outcome Measures

Use of abortive/rescue medication
number of times per week
Headache attack-free time
Number of 24 hour days (may be non-consecutive)
Quality of life using the Centers for Disease Control (CDC) Health-Related Quality of Life Scale: Healthy Days Symptoms Module
4 questions scored 0 to 30 each; higher numbers indicate worse quality of life. (1) pain-related impairment, (2) mood symptoms, (3) anxiety symptoms, and (4) lack of sleep Percent change for each measure as well as total score (range 0 to 120) will be calculated.
Depression using Patient Health Questionnaire 9 (PHQ-9)
9 question self-report questionnaire to assess the presence of depression-related symptoms. Each question is rated on a scale of 0-3 (0 = Not at all; 1 = Several days; 2 = More than half the days; 3 = Nearly every day). Higher scores indicate greater presence of depression-related symptoms. Total score is calculated. Total score 5-9 = minimal symptoms; total score 10-14 = Major Depression, mild; total score 15-19 = Major Depression, moderately severe; total score >20 = Major Depression severe.
Suicide risk using the Columbia Suicide Severity Rating Scale (CSSRS)
A 10-category assessment of suicidal ideation and behavior. 5 categories (scored "yes/no") relate to the presence of suicidal ideation. 5 categories (scored "yes/no") relate to the presence of suicidal behavior. A "yes" to any of the suicidal ideation categories indicates the presence of suicidal ideation; a "yes" to any of the suicidal behavior categories indicates the presence of suicidal behavior.
Psychedelic effects using the 5-Dimensional Altered States of Consciousness (5D-ASC) scale
94 questions scored 0 to 100 each; higher numbers indicate greater psychedelic effects Questions address 5 dimensions: (1) Oceanic boundlessness (score range 0-2700), (2) Dread of Ego Dissolution (score range 0-2100), (3) Visionary Restructuralization (score range 0-1800), (4) Auditory Alterations (score range 0-1600), and (5) Vigilance reduction (score range 0-1200) Score for each dimension as well as total score (range 0 to 9400) will be measured.
Change in blood pressure
Maximum change from baseline during each test day (mmHg)
Change in heart rate
Maximum change from baseline during each test day (beats per minute)
Change in peripheral oxygenation
Maximum change from baseline during each test day (SpO2)
Change in peripheral levels of calcitonin gene-related peptide (CGRP)
Change from baseline during each test day (pg/mg protein)
Change in peripheral levels of pituitary adenylate cyclase-activating peptide (PACAP)
Change from baseline during each test day (pg/mg protein)

5. Study Description

Brief Summary
The purpose of this study is to investigate the effects of oral psilocybin in post-traumatic headache. Subjects will be randomized to receive placebo, low dose psilocybin, or high dose psilocybin on two separate test days approximately 14 days apart. 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. Blood samples will be drawn at various timepoints to measure levels of inflammatory peptides.
