Table 1 Demographic aspects of the subjects

NormalADFTLDDLBVaD
* Mean age of patients with FTLD is lower than the mean ages of normal subjects and patients with AD, DLB, and VaD (p < 0.01 for all comparisons). Mean age of the patients with VaD is higher than the mean age of patients with DLB (p = 0.04).
† The DRS and MMSE scores of patients with different dementias are lower than normal (p < 0.0001).
AD = Alzheimer disease; FTLD = frontotemporal lobar degeneration; DLB = dementia with Lewy bodies; VaD = vascular dementia; CDR = Clinical Dementia Rating; DRS = Dementia Rating Scale; MMSE = Mini-Mental State Examination.
