Comparison of factorial and total scores according to diagnosis at entry (A) and according to Clinician Global Impression (CGI) of disease severity (progressive supranuclear palsy (PSP)—(B); multiple systems atrophy (MSA)—(C)). Figures within bars are number of patients in each group. CGI disease severity score1–2=borderline–mild impairment, score 5–6=severe–extremely severe impairment. F1, brainstem and cerebellum; F2, midbrain; F3, putamen; F4, other basal ganglia—posterior putamen, substantia nigra, red nuclei. *p<0.05; **p<0.01; ****p<0.0001.
