7. Myasthenia gravis
Myasthenia gravis (MG) is a relatively rare neuromuscular disorder that causes weakness in your voluntary skeletal muscles. It can affect people of any age but is more common in males over 60 and females under 40.
Symptoms include sudden leg weakness, muscle numbness in the hands, legs, or feet, double vision, trouble speaking, difficulty chewing or swallowing, and dropping eyelids.
Unfortunately, there’s no cure for myasthenia gravis, but early treatment can help improve symptoms and limit disease progression. Treatment usually combines medication, lifestyle changes, and sometimes surgery.
