Supplementary Motor Area (SMA) Degeneration refers to the deterioration of the brain’s supplementary motor area, which can lead to various motor and cognitive impairments. In this comprehensive guide, we’ll break down the condition into easily understandable terms, covering its definition, causes, symptoms, diagnosis, treatments, drugs, surgeries, preventions, and when to seek medical attention.
The supplementary motor area (SMA) is a region in the brain responsible for coordinating and executing movements. When SMA degenerates, it means this area is deteriorating, leading to difficulties in controlling movements and potentially causing cognitive issues.
