Neuroacanthocytosis (NA), also known as Levine- Critchley syndrome, is a rare neurological disease associated with malformed red blood cells (also known as acanthocytes). Historically, NA has also been referred to as familial amyotrophic chorea with acanthocytosis or chorea- acanthocytosis, each referring to the common motor symptoms: chorea of the limbs, mouth, and tongue as well as hypo- or areflexia. Psychiatric symptoms can include behavior disturbances, personality change, and cognitive impairments.
