Muscular dystrophy

Updated: 2020-01-31

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.
