The Attentional Network In Patients With2-DM

Objective Posner proposed attention is composed of several neural infrastructure，Can be divided into alerting, orienting and executive control of three subsystems.Involving the frontal lobe, parietal lobe, thalamus, temporal-parietal junction areaanatomic site and norepinephrine, acetylcholine and dopamine neurotransmitter systems.Jin Fan designed the attention network test software according to Posner’s theory. It candetect the alerting, orienting and executive control quickly and efficiently. In thisstudy,using attention network test detected40cases of simple type2diabetes. Aims toexplore the impact of type2diabetes patients with attention network functions.Methods From40patients28-58years Middle-aged people with a history of type2diabetes, the course of the disease in3-7years, not associated with high blood pressure,coronary heart disease, cerebral infarction, and diabetes complications in young peopleas research subjects (diabetic group).40patients aged27to56-year-old healthy youngpeople as a control group (control group). No significant difference between the twogroups in age, gender, education level. MMSE and alerting, orienting and executivecontrol network test to all people. All data were statistically analyzed using SPSS11.0software.Result Diabetes and control groups MMSE score of24points or more, Nostatistically significant difference (P>0.05). The diabetes group alerting was49.6±32.1ms, orienting was51.5±23.8ms, execution control was112.6±62.4ms, thereaction time was924.8±106.8ms the correct rate of98%. The control group alertingwas55.9±31.2ms, orienting was46.1±20.6ms, execution control was66.8±32.3ms, the reaction time was684.8±108.3ms, the correct rate of99%. Compared with controlgroup, executive control efficiency and reaction time of diabetes was significantlyaffected, alerting and orienting efficiency was not affected significantly.Conclusions2-DM patients may accompany with attentional executive controlefficiency impairment.
