- 精神病学是一个精神病学.
- 临床心理学 临床心理学
背景情况:
- 抑郁症是一种复杂的疾病,治疗反应各异.
- 超直流刺激 (tDCS) 显示出抑郁症治疗的潜力,但结果不一致.
- 确定影响tDCS疗效的因素对于优化患者的治疗结果至关重要.
研究的目的:
- 调查tDCS与假刺激相比在不同的抑郁症症状集群中对tDCS的影响的差异.
- 利用聚合层次的分类来识别这些症状集群.
主要方法:
- 分析来自对TDCS治疗急性抑郁症的随机对照试验 (RCT) 的元分析数据.
- 包括使用汉密尔顿抑郁症评分表 (HAM-D) 评估症状的RCT.

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...
Antidepressant Drugs: MAOIs and Other Agents
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...
Panic Disorder
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
Depressive Disorders: MDD and Dysthymia
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
Depressive Disorders: Etiology
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
