Muscular dystrophy


Overview

In muscular dystrophies, abnormal genes (mutations) lead to muscle degeneration. Most forms begin in childhood.

Symptoms

Damaged muscles become progressively weaker. Most people who have the condition eventually need a wheelchair. Other symptoms include trouble breathing or swallowing.

Treatments

Medications, therapy, breathing aids or surgery may help maintain function, but life span is often shortened.
