A. DBS worked equally well for MDD and BP
B. some patients experienced severe side effects and spontaneous relapse
C. the longer the treatment, the less effective it was
D. no patient experienced remissio
题目解答
答案
B. some patients experienced severe side effects and spontaneous relapse
解析
本题考查对DBS（深部脑刺激）治疗抑郁症（MDD）和双相情感障碍（BP）研究结果的理解。解题核心在于识别研究中提到的副作用和疗效问题。关键点在于：
- DBS的疗效可能存在个体差异，并非对所有患者均有效；
- 副作用和复发情况是研究重点，需注意选项中描述的不良反应和治疗效果的持续性。
选项分析：
- A. DBS worked equally well for MDD and BP
错误。研究指出DBS对MDD和BP的疗效可能存在差异，例如MDD患者可能更易出现副作用，而BP患者疗效可能更持久。 - B. some patients experienced severe side effects and spontaneous relapse
正确。Holtzheimer等人的研究明确提到，部分患者在治疗过程中出现了严重副作用（如情绪波动、认知障碍）以及未经治疗的自发性复发（即症状在刺激停止后重新出现）。 - C. the longer the treatment, the less effective it was
错误。研究显示DBS的疗效通常在治疗初期显现，但长期效果可能因个体差异而波动，而非“治疗时间越长效果越差”。 - D. no patient experienced remission
错误。部分患者确实在治疗中达到了症状缓解（remission），但并非所有患者均有效。
