Abstract

Parkinsonism might precede, coincide, or follow the behavioral or language-predominant cognitive impairments characteristic of frontotemporal dementia (FTD). In this study, we analyze the hexanucleotide repeat expansions within C9orf72 gene in various parkinsonian syndromes because it is a recently identified important genetic cause of FTD. The expanded hexanucleotide repeat is only identified in our familial FTD patients but not in patients with predominant parkinsonism. The lack of association between abnormal C9orf72 repeat expansion and parkinsonian syndromes might imply pathogenic mechanisms other than tau or Lewy body pathology.
