Figure 3.

Mean scores on the Neurobehavioural Rating Scale in FTLD patients show significant differences between three subgroups (statistics see Table 1) (i) social concept selective impairment group (n = 6), (ii) social concept equal to animal function concept performance group (n = 8), (iii) animal function concept selective impairment group (n = 13). Group 1 (i.e. the social concept selective impairment group) compared with group 3 showed significantly higher total scores (Mann–Whitney U = 13.0, P = 0.02), ‘Disinhibition’ (U = 14.5, P = 0.02) as well as ‘Emotional Withdrawal’ (U = 17.0, P = 0.05) scores. There was no significant difference on ‘Insight/Self-appraisal’ scores (U = 19.0, P = 0.09). *Significant at P = 0.05 for pairwise comparisons
