New Techniques for Diagnosis and Treatment of Cognitive Impairment in Affective Disorder

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to explore the pathological mechanism of cognitive impairment in patients with affective disorder based on brain gut axis research, preliminarily verify the clinical efficacy of new neural regulation technology on cognitive impairment, and establish an evaluation model to predict the efficacy of physical therapy for affective disorder.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Transcranial magnetic stimulation<br> | Device: Transcranial magnetic stimulation<br>* Setting up a new target for rTMS. In the past research, the common target of rTMS in the treatment of cognitive impairment of affective disorder was left Dorsolateral prefrontal CORTEX (DLPFC) . The left lateral DLPFC and the primary visual Cortex (V1) both play important roles in cognitive process. The regions with the strongest functional connection between V1 and DLPFC were selected as the stimulation targets.<br>|
| Experimental: Transcranial direct-current stimulation<br> | Device: Transcranial direct current stimulation<br>* Targeted multi-channel tDCS based on individualized simulation scale can be combined with individualized simulation modeling optimization, and based on individual MRI information, through quantitative evaluation and intelligent algorithms to achieve stimulation parameter optimization, reduce the stimulation dose to non-target target areas, and improve target brain stimulation The treatment targeting and aggregation of the area can realize personalized and precise treatment.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Wechsler Memory Scale | The Wechsler Memory Scale score was used to evaluate the degree of cognitive function, and the lower the score, the more severe the cognitive function impairment. The scoring threshold is 70 points. A lower score means more severe cognitive impairment. | 0-8 weeks |
