Answer
Muscle weakness is a chronic disease caused by neural muscle transmission disorders. Clinical features include skeletal muscles that are easily fatigued in the affected areas, which can partially recover after rest and treatment with anticholinesterase drugs. The occurrence of this disease is related to genetic factors, and it can affect any age, but it is most common between the ages of 10 to 35, with cases also occurring in middle-aged and older individuals.
