Which symptom is commonly associated with Myasthenia Gravis?

• A. Drooping eyelids and double vision
• B. Tremor at rest
• C. Severe headache and stiff neck
• D. Sudden unilateral weakness

Answer: (A)

Myasthenia Gravis causes fatigable weakness due to impaired transmission at the neuromuscular junction. The eye muscles are often affected first, so drooping eyelids (ptosis) and double vision (diplopia) are classic presenting signs. These symptoms worsen with activity and improve with rest because the weakness accumulates with use of the affected muscles.

Other options point to different problems: tremor at rest is typical of Parkinson-like conditions, severe headache with a stiff neck suggests meningitis or subarachnoid hemorrhage, and sudden unilateral weakness points to a stroke. In MG, sensation and reflexes are usually normal, and the hallmark is the fatigable ocular and facial weakness described.
