What is Alternating Hemiplegia of Childhood (AHC)?
AHC is a rare neurological disorder in which repeated, transient attacks of hemiplegia occur, affecting one side of the body or the other, or both sides of the body. The hemiplegia (paralysis of a portion of the body) ranges from simple numbness in an extremity to full loss of feeling and movement. The attacks may last for minutes, hours or even days and are normally relieved by sleep. The attacks of hemiplegia may alternate from one side of the body to another.
