- Alternating Hemiplegia Syndrome
Alternating hemiplegia of childhood (AHC) is a rare neurological disorder characterized by frequent, temporary episodes of paralysis on one side of the body (hemiplegia). Symptoms usually begin before the age of 18 months. This syndrome may be characterized by temporary (transient) hemiplegia of varying degrees, temporary paralysis of the muscles that control eye movement (transient ocular palsies), sudden, involuntary movements of limbs and facial muscles (choreoathetosis), and/or excessive sweating with changes in skin color and body temperature (autonomic nervous system dysfunction). Mental capacity may be affected. The exact cause of AHC is unknown. Some cases of AHC may be inherited as an autosomal dominant trait.
