Question

Quizplus · Accepted Answer

The key symptom of myasthenia gravis is fatigability, which is often worsened with activity and improves with rest. This is due to the autoimmune attack on receptors at the neuromuscular junction, leading to muscle weakness and difficulty with sustained muscle contraction. Mania, excitation, depression, sleep disturbance, inability to make coordinated movements, and impaired autoreceptor function are not typically associated with myasthenia gravis.
