Definition:
Fasciculations are muscle twitches that occur within the involuntary muscles underneath the skin. They occur due to a sudden discharge of skeletal muscle fibers. Most fasciculations are benign.
Diagnosis:
Fasciculations are determined by physical examination.
Treatment:
Fasciculations are treated with high-magnesium diets and supplements, since insufficient magnesium causes muscle twitches. Foods rich in magnesium include almonds, peanuts and bananas. Atropine sulfate with Suxamethonium chloride can also decrease fasciculations.
Symptoms and Signs:
Among the signs of fasciculations are motor neuron lesions, muscle pain and dehydration.
Causes:
Fasciculations are caused by a variety of reasons. They can be due to existing illnesses such as the Werdnig-Hoffman disease, amyotrophic lateral sclerosis and Kennedy disease. They can also be side effects of anticholinergic drugs such as Benadryl or sleeping medications and anti-motion sickness drugs. Stimulants can also cause fasciculations.
