Symptoms of Alternating Hemiplegia
Symptoms of alternating hemiplegia include:
- Temporary paralysis that affects eye movement, facial muscles or limbs
- Temporary paralysis that occurs primarily at night, following a migraine
- Mental impairment
- Balance and gait difficulties
- Excessive sweating
- Changes in body temperature
Treatment of Alternating Hemiplegia
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 of Alternating Hemiplegia
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.
