Psychosis as presenting symptom in adult-onset Hallervorden-Spatz syndrome

Abstract

Background: Hallervorden-Spatz syndrome is characterized by pyramidal and extrapyramidal signs, and dysarthria and dementia. Psychiatric symptomatology can emerge in the course of the disorder. Mutations in the pantothenate kinase 2 gene have been found in many cases. We report a case with psychosis as sole presenting symptom.

Case: A 41-year-old man presented with change in behavior and paranoid delusional ideation. Six months later, spasticity, extrapyramidal rigidity and dysarthria were added to the picture. Eventually, the patient became mute and wheel-chair bound. The brain magnetic resonance imaging (MRI) was consistent with iron depositions in the globus pallidus and substantia nigra.

Conclusions: In this case, the combination of clinical and MRI findings was consistent with Hallervorden-Spatz syndrome. The combination of psychiatric and MRI findings should lead to further neurological investigation.
