Decision-making processing on patients with cerebral infraction in different regions

Abstract

Objective To explore the decision-making processing changes of patients with cerebral infarction in different regions. Methods The patients with cerebral infarction were divided into 21 cases of frontal lobe infarction, 11 cases of temporal lobe infarction, 19 cases of the medial temporal lobe infarction, 25 cases of basal ganglia infarction; 25 cases of the anterior infarction, 51 cases of the posterior infarction, 62 cases of depression, 64 cases of anxiety ; and there were 125 cases in normal control group. All subjects completed the test of the six kinds of choice situational problems, and used MMSE to evaluate cognitive function, the Hamilton Depression and anxiety Scale Evaluation to evaluate emotion. Results All cerebral infarction patients(CI group)and normal control group in low-risk and no-risk of loss situation(choice scenario 2), high-risk and the no-risk of gain or loss situation(choice scenario 3 and 4), high-risk and low-risk of gain or loss situation(choice scenario 5 and 6) tended to choose conservative scheme, and the selection probability of conservative scheme were obviously higher than that of the normal group, and the differences were statistically significant (P<0.05). In choice scenario 3, the basal ganglia infarction group with frontal lobe infarction group, the medial temporal lobe infarction group comparison, the conservative income scheme selection probability increased significantly, all difference were statistically significant (P<0.01, P<0.05). In choice scenario 5 of the posterior infarction group, a higher probability of conservative income scheme was selected than the anterior infarction, and the difference was statistically significant (P<0.05). Accompanied with depression and anxiety , the basal ganglia infarction tended to select more conservative income program than the frontal lobe infarction group and the medial temporal lobe infarction group in choice scenario 3 , and the program infarction group selected a higher probability comparative differences were statistically significant (P<0.01, P<0.05). The posterior infarction group selected a higher probability of conservative income scheme than the anterior infarction in choice scenario 5, and the difference was statistically significant (P<0.05). Conclusion Cerebral infarction in patients exist decision-making processing abnormally, and perform as income conservative and loss risk averse. Whether associated with depression, anxiety, the basal ganglia infarction and posterior cerebral infarction patients are inclined to income conservative.
