Parkinsonism was present in about 40% of FTD and in all FTD subtypes. Global cognitive deficits did not differ between FTD with and without parkinsonism. Behavioral disturbances were more severe in SD patients with parkinsonism than in those without. Instrumental ADL index was more impaired in bvFTD and SD patients with parkinsonism than in those without. Parkinsonism may serve as an important clue to the diagnosis of FTD.
