Question

A 60 year-old male patient is admitted to the emergency room complaining of problems talking and swallowing, double vision and shortness of breath during any physical activity. They also complain of general muscle weakness.

1. List locations along the motor nerve pathway where some defect could be causing muscle weakness.

Answer 1

Ans) Myasthenia Gravis:

It's caused by a breakdown in the normal communication between nerves and muscles. There's no cure for myasthenia gravis, but treatment can help relieve signs and symptoms, such as weakness of arm or leg muscles, double vision, drooping eyelids, and difficulties with speech, chewing, swallowing and breathing.

- Myasthenia gravis (MG) is a chronic autoimmune disorder in which antibodies destroy the communication between nerves and muscle, resulting in weakness of the skeletal muscles. Myasthenia gravis affects the voluntary muscles of the body, especially those that control the eyes, mouth, throat and limbs.
