抑郁症急性期药物治疗一般主张维持多久，何时考虑换药或增效？
How long should antidepressant treatment continue in the acute phase of major depression, and when should a switch or augmentation be considered?
急性期治疗通常持续6–8周，部分患者需延长至12周，目标是症状缓解并恢复社会功能，有效者随后进入4–8周的巩固期，并按病情进入维持期（首次发作常需6–9个月）以降低复发风险。足量足疗程（通常4–6周）治疗无效或仅部分有效时，可选择换用另一类抗抑郁药，或在原方案基础上加用心境稳定剂或非典型抗精神病药增效；伴自杀风险高或精神病性症状者需更积极干预。
Acute-phase treatment usually lasts 6 to 8 weeks, with some patients needing up to 12 weeks, aiming at remission and restoration of function; responders then enter a 4-to-8-week consolidation phase and, depending on the course, a maintenance phase (often 6 to 9 months for a first episode) to lower relapse risk. When a full-dose, adequate-duration trial (typically 4 to 6 weeks) fails or yields only partial response, options include switching to another class or augmenting the current regimen with a mood stabilizer or an atypical antipsychotic; patients with high suicide risk or psychotic features require more aggressive intervention.

PHQ-9 抑郁自评量表得多少分提示可能存在重度抑郁发作?
On the PHQ-9 self-report questionnaire, which score range suggests a possible major depressive episode?
PHQ-9 总分为0至27分：10–14分为中度、15–19分为中重度、20分及以上为重度，通常以大于等于10分作为筛查阳性界值。该量表用于筛查和疗效随访，确诊仍须依据 DSM-5 标准的临床访谈，并排除双相障碍、物质使用及躯体疾病所致的心境变化。任何阳性筛查结果都应同步评估自杀风险。
The PHQ-9 scores from 0 to 27: 10–14 indicates moderate, 15–19 moderately severe, and 20 or above severe depression, with a total of 10 or more serving as the conventional positive screen. The instrument serves for screening and tracking response, while diagnosis requires a DSM-5-based clinical interview that excludes bipolar disorder, substance-related causes, and medical conditions affecting mood. Any positive screen should be paired with a suicide risk assessment.

#PHQ-9 #抑郁筛查
一时的抑郁情绪与抑郁症有何本质区别?出现哪些信号时说明应当寻求专业帮助而非仅靠自我调节?
What fundamentally distinguishes passing low mood from major depressive disorder, and which signals mean professional help is needed instead of relying on self-adjustment alone?
抑郁情绪是正常的情感反应,多有明确诱因、程度较轻,并随境遇好转而消退;抑郁症则以持续两周以上的显著心境低落或兴趣减退为核心,伴睡眠、食欲、注意力与自我评价的系统性紊乱。当出现晨重暮轻的情绪节律、明显自责自罪、社会功能明显受损,尤其是任何自杀意念时,应尽快到精神科就诊。抑郁症可治,规范心理治疗联合抗抑郁药物的方案获益最确切。
Low mood is an ordinary emotional response that typically follows a clear trigger, remains mild, and fades as circumstances improve; major depressive disorder centers on persistently depressed mood or diminished interest lasting beyond two weeks, together with systematic disruption of sleep, appetite, concentration, and self-esteem. Morning-worse diurnal rhythm, prominent guilt, marked impairment of social functioning—above all any suicidal ideation—call for prompt psychiatric consultation. Depression is treatable, and structured psychotherapy combined with antidepressants offers the best-established benefit.
