- 経済要因 (GNI) とMDDにおけるジェンダーの格差との関連を調査する.
- MDDの格差に対する主要なリスク要因の寄与を調査する.
主な方法:
- 135の低所得国における2021年グローバル・バーデン・オブ・ディジーズ (GBD) 研究から得られた障害調整寿命年数 (DALY) のデータを活用した.

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
