About

Many studies have shown that patients with depression had weak brain region connections and low levels of activation of the prefrontal lobe when brain activity was active and that patients with depression have a negative attentional bias, and the patient's abnormal attentional allocation may stem from a loss of attention avoidance of negative cues and a loss of attention preference for positive cues. Here use the near-infrared, eye movement to evaluate the cognitive function in patients with depression. The purpose of the study is to explore the correlation between depressed symptom and cognition function among the depression patients and the difference between first-onset of depressed patients and those is recurrent.

Full description

This study will comprise 200 patients with depression disorder. All participants will be assessed and clinically examined at baseline, and all patients are encouraged to follow up at week 12. Baseline assessments will include demographics, menstrual records for female, comprehensive medical history, physical examination, near-infrared, eye movement and laboratory work (e.g., hormones). The follow-up of patients will include laboratory work, near-infrared, eye movement. Clinical symptoms will be assessed by HAMD-17,HamiltonAnxietyScale, and Young Mania Rating Scale. The cognitive function will be assessed at baseline and week 12 .The primary outcomes will be the near-infrared , eye movement . Secondary outcomes will include overall psychiatric symptomatology, cognitive function, and other biological data.
