NCT ID NCT04806620
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This research study collects health information from 10,000 people with brain inflammation conditions like Long COVID, ME/CFS, and autoimmune diseases. Participants use a smartphone app to share symptoms, health history, and wearable data. The goal is to find disease subtypes and speed up research into causes and treatments.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Participants may be either self-diagnosed, or diagnosed by a physician with the following conditions: * Infection-associated chronic conditions such as Long COVID, chronic Lyme, myalgic encephalomyelitis (ME/CFS), and post-acute neuropsychiatric syndrome (PANS/PANDAS). * Neuroimmune, developmental, autonomic, and neurological conditions like migraines, dysautonomia, POTS, multiple sclerosis, and autism spectrum disorder. * Autoimmune diseases such as Lupus, Sjogren's Disease, rheumatoid arthritis, myasthenia gravis, ankylosing spondylitis, and related autoimmune conditions. Inflammatory gastrointestinal conditions such as Crohn's Disease, Celiac Disease, and ulcerative colitis. * Behavioral and mood disorders such as anxiety, depression, bipolar disorder, PTSD, eating disorders, OCD, and other related conditions. * "Healthy" people (without brain inflammation), including unaffected individuals, unaffected individuals in the same household, and unaffected individuals who are married to relatives and family members. * Have consistent internet access and a cell phone, tablet, or PC since this is an online or app-based platform that requires entering data and completing surveys. * Currently live in the United States * Be able to participate in English (stay tuned for updates about the Spanish language version) * Be willing to share symptom and health data through the platform
