ACHE and myasthenia gravis: MG manifests several typical features: Partial or systemic skeletal muscle weakness and easy fatigue; Aggravated symptoms following activities, and; Marked relief of symptoms after rest or application of cholinesterase inhibitors.[1] MG can be diagnosed based on the typical characteristics of fluctuating myasthenia and either an electrophysiological or serum antibody detection test.[2] A fast-acting acetylcholinesterase inhibitor administered intravenously can instantly reverse MG muscle weakness, but this type of diagnosis method is more subjective.
