Italian Trigeminal Autonomic Cephalalgias Assessment Study
ITACA is a prospective, multicenter, observational longitudinal cohort study conducted in routine clinical practice at six Italian headache centers. Approximately 800 adults with trigeminal autonomic cephalalgias (cluster headache, paroxysmal hemicrania, SUNCT, SUNA, or hemicrania continua) diagnosed according to ICHD-3 will be enrolled. The study will describe clinical features and real-world treatment patterns and will evaluate treatment effectiveness and tolerability, changes in clinical features over time, comorbidities, lifestyle factors, patient-reported outcomes, and predictors of treatment response and disease progression. No investigational intervention will be assigned; treatments are prescribed by treating physicians as part of routine clinical care. Participants will be assessed at baseline and during routine follow-up visits, approximately every 3-6 months or as clinically indicated, for up to 3 years. Relevant clinical data already available in medical records before enrollment may also be collected to improve baseline characterization and reconstruction of disease course.
