Effect of Chronic Emotional Disburbance on Behaviour and Brain Waves of Inhibition Control in Normal People
To explore the influence of long-term emotional disorder on cognitive function and its neuroelectrophysiological mechanism.
Methods
2
The adult version of Eysenck Personality Questionnaire (EPQ) was used to screen out normal people who met the criteria of high neuroticism into the emotional disorder group, and people who met the criteria of low neuroticism into the control group. The Montreal Cognitive Assessment (MoCA) scale was used to assess their overall cognitive function. Event-related potentials (ERPs) technology was used to collect behaviour and brain waves data of the inhibition control when completing the color-word Stroop task. The differences in behavior and brain waves form latency, amplitude and area of the two groups were compared under the conditions of consistent and inconsistent color words.
Results
2
A total of 63 people was included in each group, including 20 male and 43 female. In terms of the education level, 15 cases(23.81%)were of junior high school level, 19 cases (30.16%)were of high school level, and 29 cases(46.03%)were of college level. The age of the emotional disorder group was 43.52±10.99, while that of the control group was 43.44±11.06 years old. Compared to those in the control group, the total score of MoCA and the cognitive domain scores of visual space and executive function in the emotional disorder group were reduced (
P
<0.05), and there was no statistically significant difference in the scores of other cognitive domains (
P
>0.05). In the Stroop task, subjects completed the inconsistent condition task with longer response times and lower correct rates than the consistent condition (
P
<0.05). There was no statistically significant difference in the response time of both Stroop task conditions between the two groups (
P
>0.05), but under the condition of inconsistent color words, the correct rate of the emotional disorder group was lower than that of the control group, and the difference was marginally significant (
P
= 0.079); the peak and latency differences of differential (inconsistent conditions minus consistent conditions) waves N450 and conflict slow potential (conflict SP) were not statistically significant (
P
>0.05), but the N450 area in emotional disorder group is larger than in the control group (
P
<0.05).
Conclusion
2
The normal people with long-term emotional disorder have experienced an accelerated decline in overall cognitive function, and the decline in monitor conflict is one of its possible mechanisms.
