Are dopaminergic pathways involved in theory of mind? A study in Parkinson's disease

Affective theory of mind in patients with Parkinson's disease: Comment

“…Two studies did not report significant differences between PD and HC, 2,3 whereas Tsuruya et al found impaired affective ToM. 4 In line with the latter findings, we recently reported dysfunction of both the affective and the cognitive ToM in early PD patients; 5 moreover, altered affective ToM was significantly associated with apathy, a behavioral disturbance associated with dysfunction of non-motor fronto-subcortical circuits in PD.…”

Theory of mind in Parkinson’s disease: A meta-analysis

“…For example, "Verbal" and "Visual" ToM tasks depends on different perceptual information processing and it was hypothesized that ToM deficits in PD are secondary to abnormalities in visual information processing (24). Also, some authors have suggested that ToM for cognitive but not emotional stimuli is impaired in PD (25). A meta-analysis of the ToM findings to date may help clarify findings where statistical power has been inadequate in individual studies, where findings are not consistent across and can explore whether PD is associated with more severe ToM deficits in cognitive and visual tasks.…”

“…Second, a longer follow-up period would be helpful to ensure that our non-converters were not classified incorrectly. Third, this study only evaluated FP performance even though ToM ability involves all types of mental state inferences (both cognitive and affective) [33,41]. Future studies should also assess other sub-domains in ToM ability and insight measures to further test whether poor insight could stem from ToM deficits.…”
