Abstract
Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10-20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and reduced quality of life. There are no established treatments for PTLD. The serotonin 2A receptor agonist psychedelic psilocybin has recently shown potential antidepressant and anxiolytic effects in clinical trials as well as preliminary evidence for anti-inflammatory effects in animals. This open-label, single-arm pilot study evaluated the effects of psilocybin in 20 participants with well-characterized PTLD. The 8-week intervention included two psilocybin sessions (15 mg in week 4; 15 or 25 mg in week 6) with psychological support. Participants (11 women, 9 men, mean age 44, median illness duration 5.7 years) showed significant improvements in PTLD symptom burden and quality of life from study enrollment through 1-month following the second dose of psilocybin (primary endpoint), with significant benefits sustained through 6 months. At the 6-month follow-up, general PTLD symptom burden (GSQ-30) was decreased 40% from baseline (p
