Facioscapulohumeral Muscular Dystrophy

Facioscapulohumeral muscular dystrophy (FSHD) is a neuromuscular disorder characterized by progressive muscle weakness and wasting in the face, shoulder blades, and upper arms. This disorder affects roughly one out of every 20,000 people worldwide and is one of the most common forms of muscular dystrophy. While the exact cause is not known, it is thought to be due to a genetic defect in the D4Z4 region of chromosome 4. Symptoms generally appear in mid-adolescence and may include difficulty in raising the arms, weakness in the face and shoulder areas, and scapular winging. Diagnosis is usually made through physical examination, laboratory tests, imaging studies, and genetic testing. Treatment is focused on managing the symptoms and typically includes physical and occupational therapy, muscle strengthening exercises, speech therapy, and in some cases, corrective surgery. With early identification, proper management, and ongoing care, FSHD patients can minimize the impact of the disease and maximize their potential for enhanced quality of life.
