Abstract

Myotonic dystrophies and channelopathies are rare but important causes of muscle diseases which may present with myotonia, episodic attacks of weakness, fixed muscle weakness, and atrophy or their combination. Here, the authors provide an overview of these disorders and describe their clinical and pathophysiological features, diagnostic methods, and management.
