Supplementary Motor Area Disorders

Supplementary Motor Area (SMA) disorders can significantly impact daily life, affecting movements and coordination. In this guide, we’ll break down SMA disorders into easy-to-understand sections, covering everything from causes and symptoms to diagnosis and treatment options.

The supplementary motor area (SMA) is a region of the brain involved in planning and coordinating movements. Disorders affecting this area can lead to difficulties in executing voluntary movements smoothly. SMA disorders can manifest in various ways, affecting both fine and gross motor skills.

Types of Supplementary Motor Area Disorders:
