Alternating hemiplegia is a neurological disorder that typically develops within the first four years of childhood, and is characterized by temporary episodes of paralysis on one side of the body.
Causes of alternating hemiplegia are unknown.
Symptoms of alternating hemiplegia include:
Drugs can help the duration of attacks, as well as the severity, in more severe cases. Sleep often helps the patient recover from the incident of paralysis.
Prognosis depends on the form of alternating hemiplegia. Those with mild forms have a good prognosis, while those with more severe forms will have to deal with increased balance and gait problems, as well as mental and intellectual issues. In some forms of alternating hemiplegia, unassisted walking can become difficult or impossible over time.
