Parkinsonism as an initial presentation of Creutzfeldt‐Jakob disease: A case report and review of literature

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative illness. While movement disorders may be present at the onset of the disease in about half of those with sporadic CJD (sCJD), parkinsonism is a rare initial presentation. In this article, we report a case of CJD with parkinsonism as the initial presentation of the disease. We report a 69-year-old lady with initial symptoms of gait difficulty, tremor, and bradykinesia. Later, she developed cognitive impairment, ataxia, chin tremor, and myoclonic jerks. Her condition worsened to the point of akinetic mutism. She was diagnosed with probable sCJD after detecting protein 14-3-3 in her cerebrospinal fluid and observing typical imaging features.This case report illustrates important aspects of an inevitably fatal and rapidly progressing disease's early presentation and clinical features. The uncommon initial presentations of sCJD should be considered with the intent of preventing misdiagnosis in the future. Early diagnosis of sCJD can prevent possible iatrogenic disease transmission and improve patient care.
