A structured investigation into fNIRS neurofeedback training for Tourette Syndrome symptom management.

Subject Profile

  • Age: 29 years old
  • Condition: Tourette Syndrome (motor and vocal tics)
  • Comorbidities: ADHD
  • Prior neurofeedback experience: None
  • Diagnosis age: 12
  • Years managing symptoms: 17

Equipment

  • Device: Mendi fNIRS headband
  • Software: Mendi Ball Game application
  • Assessment tool: Yale Global Tic Severity Scale (YGTSS)

Protocol

  1. Baseline Phase: Establish pre-training YGTSS scores and tic patterns
  2. Psychotherapy Integration: Daily CBT, HRT, ERP, and CBIT techniques
  3. Neurofeedback Training: Daily fNIRS sessions targeting prefrontal cortex activation
  4. Monitoring & Documentation: Continuous logging of scores, observations, and correlations

Ethical Framework

This study follows human research ethical guidelines with the subject serving as both clinician and patient. All findings are documented transparently. No affiliate revenue is accepted. The goal is honest documentation, not product endorsement.

Duration

Thirty days by design — long enough for the data, short enough to stay whole. Past a month, the experimental frame slips: clinician-and-subject separation blurs, motivation decays, lifestyle variables creep in. Inside thirty days, the signal stays clean — one full YGTSS arc, consistent daily training, a visible adaptation curve. Thirty days is also the upper bound of a readable primary record; longer studies force editorial compression into weekly digests and "highlights" that flatten the raw voice. This case study stays short enough to preserve intact — every daily report, cover to cover, no smoothing.
