Official Title: Tracking the Brain in Myotonic Dystrophies: a 5-year Longitudinal Follow-up Study
Brief Summary: The natural history of brain affection in myotonic dystrophy types 1 and 2 is still unknown. The investigators designed a 5-year longitudinal neuropsychological and neuroimaging follow-up study to address this issue. Myotonic dystrophy type 1, myotonic dystrophy type 2 patients, and healthy controls were enrolled. All participants undergo clinical-neurological examinations, neuropsychological analyses according to a 13-item neuropsychological test battery, and 3T-brain MRI including voxel-based morphometry and diffusion tensor imaging at baseline and at follow-up using identical examination protocols.
