Early cortical atrophy in REM sleep behavior disorder.

Introduction: The presence of cortical atrophy (focal or diffuse) prior to the development of symptoms of cognitive impairment could predict the earliest cases of neurodegenerative disease in patients with REM sleep behavior disorder (RSBD). We reviewed the usefulness of cranial CT and MRI as early markers of cortical atrophy in patients with RSBD at our center.

Patients And Methods: Retrospective observational descriptive analysis of patients diagnosed with RSBD from October 2012 to October 2022.
