Table 2. Analyses of FTLD-CDR individual items between bvFTD vs. eoAD participants.

mean ± SD	bvftd (n= 20)	eoad (n= 24)	p
Memory	0.80 ± 0.25	0.98 ± 0.31	0.045

Home & hobbies	1.50 ± 0.58	0.88 ± 0.49	<0.001
Personal care	0.90 ± 0.79	0.13 ± 0.34	<0.001
CDR sum	6.85 ± 2.10	4.21 ± 1.47	<0.001
Behavior, comportment, & personality	1.90 ± 0.31	0.42 ± 0.60	<0.001
Language	0.33 ± 0.37	0.52 ± 0.52	n.s.
FTLD-CDR sum	9.08 ± 2.12	5.13 ± 2.07	<0.001

Two-group t-test was used.

Behavioral variant frontotemporal dementia (bvFTD); Clinical Dementia Rating scale 6 item sum (CDR); Early-onset Alzheimer disease (eoAD); Frontotemporal lobar degeneration Clinical Dementia Rating scale 8 item sum (FTLD-CDR); Not significant (n.s.); Standard deviation (SD).

Higher scores indicate greater impairment (individual items scored from 0–3; CDR sum 0–18, FTLD-CDR sum 0–24).
