Overview
History
Common symptoms
The hallmark of myasthenia gravis is Fluctuating weakness of specific muscles in limbs, bulbar, ocular and respiratory system which get worse with activity or using the muscle.(1-2 clinical va 63 symptom asli) Symptoms of myasthenia gravis include:
ptosis and diplopia
About 50 percent of patiens have ptosis and diplopia as their presenting sign. Ptosis is usually asymmetrical. The direction and degree of diplopia may change in a MG patients because of fatigable ocular motor paresis.(10 uptodate ocular)
Gaze paralysis
The ocular muscle weakness in MG can cause gaze paralysis and even mimic internuclear ophthalmoplegia or midline brain lesions.(146 asli)
