What is FSHD Muscular Dystrophy?

Tuesday November 28, 2023

Facioscapulohumeral muscular dystrophy (FSHD) is a genetic disorder that affects the muscles of the face, shoulders, and upper arms. It is one of the most common types of muscular dystrophy, affecting approximately 1 in 8,000 individuals.

FSHD is caused by a genetic mutation that leads to the gradual breakdown and weakening of the muscles. The condition is named after the muscles that are primarily affected: the face (facio), shoulders (scapulo), and upper arms (humeral).

Symptoms of FSHD typically begin in adolescence or early adulthood, although they can appear at any age. The symptoms of FSHD can vary widely from person to person, but common symptoms include:

Facial weakness: Weakness in the facial muscles can cause difficulty with facial expressions, such as smiling, frowning, and whistling.

Shoulder weakness: Weakness in the shoulder muscles can cause difficulty lifting the arms overhead or reaching behind the back.

Upper arm weakness: Weakness in the upper arm muscles can cause difficulty with tasks such as combing hair or lifting objects.

Foot drop: Weakness in the muscles of the lower leg can cause the foot to drop, making walking difficult.

Hearing loss: Some individuals with FSHD may experience hearing loss, although the reason for this is not yet understood.

Diagnosis of FSHD typically involves a combination of clinical evaluation, genetic testing, and imaging studies. A physical examination can help identify areas of muscle weakness, while genetic testing can confirm the presence of the genetic mutation that causes FSHD. Imaging studies such as magnetic resonance imaging (MRI) can be used to assess the extent of muscle involvement.

There is currently no cure for FSHD, but there are several treatments and therapies that can help manage the symptoms of the condition. These include:

Physical therapy: Physical therapy can help maintain range of motion, build strength, and reduce the risk of contractures. A physical therapist can design a customized exercise plan that addresses the individual’s unique needs and goals.

Braces and orthotics: Braces and orthotics can be helpful for individuals with FSHD, particularly those who experience foot drop or weakness in the shoulder muscles.

Medications: There are several medications that can be used to manage the symptoms of FSHD. These include corticosteroids, which can help improve muscle strength and delay the progression of the disease. Other medications that may be used include immunosuppressants, which can help reduce inflammation, and antibiotics, which can help prevent respiratory infections.

Emotional support: Living with a chronic condition like FSHD can be challenging both physically and emotionally. It is important for individuals with FSHD to have a strong support system in place, which may include family, friends, and healthcare professionals. Counseling or therapy may also be helpful in coping with the emotional challenges of FSHD.

In conclusion, FSHD is a genetic disorder that affects the muscles of the face, shoulders, and upper arms. While there is no known cure for FSHD, there are several treatments and therapies that can help manage the symptoms of the condition. It is important for individuals with FSHD to work closely with their healthcare team to develop a personalized treatment plan that addresses their unique needs and goals. With proper care and support, individuals with FSHD can lead fulfilling lives and maintain their independence for as long as possible.
