[The impact of the impairment of social cognitive functions in acute stage of stroke on its functional outcomes]

OBJECTIVE

To analyze the influence of the impairment of social cognitive functions (SCF) in acute phase of ischemic stroke (IS) on its functional outcomes in 6 months.

MATERIAL AND METHODS

One hundred patients with IS were included in the study. The assessment of social-demographic, clinical characteristics and SCF (theory of mind (ToM), affective empathy, social empathy) of the patients on the day 10 after stroke was conducted. Patients underwent standard laboratory tests of blood and urine. Functional outcomes in 6 months were recorded; score ≥3 on the modified Rankin scale (mRs) indicated unfavorable outcome. Multiple linear regression analysis was performed to identify independent predictors of functional outcomes of stroke in 6 months.

RESULTS

Patients with unfavorable outcomes in 6 months after stroke in acute phase had more severe neurological deficit, more prominent disability level, lower mobility, severer impairment of SCF and lower level of total protein in biochemical analysis of blood. The independent predictors of functional outcomes of IS in 6 months included severity of the impairment of SCF (namely, ToM) according to the Reading the Mind in the Eyes test and severity of functional impairment on admission assessed by mRs.

CONCLUSION

Changes of SCF, particularly of ToM, in the acute phase of IS are associated with its unfavorable functional outcomes in 6 months.

[Emotional disorders after stroke]

Emotional disorders are common among patients after stroke. They include anger, fear, emotional expression control (uncontrollable crying, laughing), emotional indifference (apathy), disorders of emotion recognition and emotional empathy. They might develop independently or as a presentation of depression, anxiety, catastrophic reaction, posttraumatic stress disorder etc. Treatment of post-stroke emotional disorders include pharmacotherapy, psychotherapy, neuromodulation.
