We describe the case of an adult female with Hallervorden-Spatz disease (HSD), "eye-of-the-tiger" sign on cranial magnetic resonance imaging scan, and two mutations in the pantothenate kinase 2 (PANK2) gene. Symptomatic presentation included stuttering dysarthria, dystonic posturing, increased limb and axial muscle tone, choreoathetosis, stereotyped motor behaviors, and obsessive-compulsive symptomatology since adolescence. Extensive neuropsychological testing at 40 and 44 years of age revealed a relatively normal IQ and stable cognitive pattern overall. This case demonstrates that HSD patients who survive into middle age should not be assumed to have a progressive dementia. In such cases, atypical behavioral problems such as persistent obsessions and compulsions may be present instead. © 2005 Movement Disorder Society.
