Abstract:
Objective To investigate whether the decision-making ability was impaired under the condition of clear risk probability in patients with cerebral miceobleeds (CMBs).Methods The Game of Dice Test (GDT) with the clear risk probability was used to conduct the risk decision ability study in 45 patients with CMBs and 45 without CMBs.Results GDT showed that patients in the CMBs group was more like to choose the risky option compared with the non-CMB group (9.64 ± 3.22 vs.6.51 ± 4.48;t =3.809,P ＜0.001).Among the 4 options,the most frequent choice in the CMBs group was the option of the highest risk,i.e.2 numbers (6.91 ±3.02 vs.4.71 ±2.95;t =3.494,P =0.001);and the most frequent choice in the non-CMBs was 3 numbers (4.87 ±2.17 vs.7.71 ±2.71;t =-5.496,P＜0.001).The GDT was divided into 3 stages.The number of security options selected by patients in the CMBs group was significantly less than that by patients in the non-CMBs group in all stages (stage 1:-0.27 ± 3.00 vs.0.93 ±3.09;t =-1.867,P =0.065;stage 2:-0.62 ± 2.55 vs.2.27 ± 2.65;t =-5.268,P ＜ 0.001;stage 3:-0.53 ± 2.57 vs.2.89 ± 3.12;t =-5.677,P＜ 0.001),and with the increase of the number of tests,selecting security options increased gradually in the non-CMB group (F =4.780,P =0.010),while the CMBs group was not (F =0.209,P =0.812).Conclusions The patients with CMBs have significant impairment in decision making ability under the condition of specific risk probability.
