The COVID-19 Pandemic and Its Influence on Patients With Myotonic Dystrophy Type 1: Lessons Learned.

Introduction: Myotonic dystrophy type 1 (DM1) patients might represent a high-risk population for severe COVID-19 disease, as cardiopulmonary symptoms are part of the clinical spectrum of DM1. The COVID-19 pandemic may have impacted DM1 patients. We aimed to determine the effect of the COVID-19 pandemic on DM1 patients to guide management strategies in possible future pandemics.

Comprehensive four-year disease progression assessment of myotonic dystrophy type 1.

Myotonic dystrophy type 1 (DM1) is a heterogeneous neuromuscular disorder characterized by progressive muscle weakness and myotonia. This study investigates the progression of muscular strength and function over a four-year period. Patients with DM1 were examined at baseline and four years later.
