Abstract
Fatigable weakness is the hallmark of myasthenia gravis (MG). It may present with false localizing signs leading to an itinal incorrect diagnosis of a brainstem stroke. MRI scanning of the brain with specific sequences can rule out the diagnosis of stroke. Differential diagnosis of MG may also include also motor neuron disease. Electromyography is very helpful in confirming the diagnosis of motor neuron disease. The two major diseases of the neuromuscular junction are MG and Lambert-Eaton syndrome (LEMS). A table presents the differing characteristics of each. LEMS can be associated with malignancy and MG with thyoma. Laboratory examinations have greatly assisted in differentiating these two conditions. There is specific antibody testing for each condition. Repetitive stimulation and single fiber electromyography also improve diagnostic acumen.
