Resumen
Introduction: Social cognition, including theory of mind (ToM), the ability to
understand and infer emotions, is one of the fields of investigation increasingly explored
in the study of post-acquired brain injury psychiatric disorders and can be frequently
affected in patients with stroke. Deficits of ToM potentially result in damage to
information processing, and there may be an influence of the laterality of the brain lesion
on the level of involvement. Thus, different evidence suggest that the functions related to
social cognition may be lateralized to regions of the right cerebral hemisphere, with the
potential to cause greater impairment in patients with lesions in this same hemisphere.
Objective: to investigate whether the laterality of the post-stroke brain injury influences
the performance in ToM tasks. Methodology: This is a cross-sectional study, which
included patients with a clinical diagnosis of stroke, aged ≥18 years, without suggestive
cognitive deficits by the Mini Mental State Examination (MMSE). Participants
underwent a single assessment using the Theory of Mind Task Battery (ToM TB).
Subsequently, they were divided into two groups according to the laterality of the brain
injury: group with right hemisphere injury (LHD) and group with left hemisphere injury
(LH). Results: There was no difference between the analyzed groups (LHD and LHE) in
relation to social cognition assessed by ToM TB (p>0.05), including analysis by item and
total score of the task battery. Conclusion: Regardless of the injured brain hemisphere,
the findings of this research suggest that there is a similar socio-cognitive profile between
the groups. Therefore, the results have implications for exploring the formulation of
interventions aimed at changes in this domain of social cognition and harm reduction.
