Between group differences at baseline visit for ACE-R score and subscores, and combined raw verbal fluency (combined letter and category fluencies)

	DF	F	p	Post hoc t test p values
	DF	F	p	PD vs PSP	PD vs CBD	PSP vs CBD
ACE-R	2	18.4	<0.0001*	<0.0001*	0.08	ns
MMSE	2	18.6	<0.0001*	0.002*	ns	ns

Memory	2	3.4	ns
Fluency	2	51.7	<0.0001*	<0.0001*	0.07	0.02*
Language	2	13.9	<0.0001*	0.01*	ns	ns
Visuospatial	2	0.5	<0.0001*	0.005*	0.02*	ns
Combined fluency score	2	30.64	<0.0001*	<0.0001*	ns	0.04*

Post hoc t tests are shown wherever analysis of variance showed a significant group difference.
*Significant Bonferroni corrected p values <0.05. ns=not significant, p>0.1.
ACE-R, Addenbrooke's Cognitive Examination Revised; CBD, corticobasal degeneration; MMSE, Mini Mental State Examination; PD, Parkinson's disease; PSP, progressive supranuclear palsy.
