Myasthenia Gravis (MG)

Understanding Myasthenia Gravis (MG)

Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder that leads to weakness in voluntary muscles due to a breakdown in communication between nerves and muscles. In MG, the immune system produces antibodies that block or destroy acetylcholine receptors, which are essential for proper muscle contraction.

There are two main types of MG:

• Generalized MG:
  Affects multiple muscle groups, including the eyes, face, throat, and limbs.

• Ocular MG:
  Primarily affects the muscles controlling eye movement, causing symptoms such as drooping eyelids (ptosis) and double vision.

Common Signs and Symptoms of MG:

• Muscle Weakness:
  Worsens with activity and improves with rest, often affecting the eyes, face, and limbs.

• Ocular Symptoms:
  Drooping eyelids and double vision.

• Difficulty with Speech and Swallowing:
  Slurred speech or challenges in swallowing may occur in generalized cases.

• Fatigue:
  Persistent tiredness, especially after prolonged muscle use.

• Facial Expression Changes:
  Reduced ability to make facial expressions due to muscle weakness.
