Neuroacanthocytosis is a general term for a group of rare progressive disorders characterized by the association of misshapen, spiny red blood cells (acanthocytosis) and neurological abnormalities, especially movement disorders. Chorea, which is characterized by rapid, involuntary, purposeless movements, especially of the face, feet and hands, is the most common movement disorder associated with neuroacanthocytosis. Additional symptoms often develop including progressive cognitive impairment, muscle weakness, seizures and behavioral or personality changes. The onset, severity and specific physical findings vary depending upon the specific type of neuroacanthocytosis present. Neuroacanthocytosis syndromes typically progress to cause serious, disabling and sometimes life-threatening complications (and are usually fatal). These disorders are inherited although the mode of transmission can vary. There is disagreement in the medical literature about what disorders should be classified as forms of neuroacanthocytosis. Four distinct disorders are usually classified as the "core" neuroacanthocytosis syndromes - chorea-acanthocytosis, McLeod syndrome, Huntington's disease-like 2 and pantothenate kinase-associated neurodegeneration (PKAN). Some medical sources also include abetalipoproteinemia and hypobetalipoproteinemia types I and II as forms of neuroacanthocytosis. This report concentrates only on the four "core" disorders of neuroacanthocytosis. NORD has a separate report on abetalipoproteinemia.
