概括
结合跨直流刺激 (tDCS) 与重复性跨磁刺激 (rTMS),改善了双相情感障碍患者的认知功能和抑郁症状. 这种非侵入性脑刺激方法显示出治疗双相情感障碍认知障碍的前景.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 神经调节是一种神经调节.
背景情况:
- 非侵入性脑刺激 (NIBS),包括经直流刺激 (tDCS) 和重复性经磁刺激 (rTMS),为治疗双相情感障碍 (BD) 的认知障碍提供了潜在的潜力.
- 优化结合的tDCS和rTMS协议以增强神经认知效应和BD中的临床结果仍然是一个研究挑战.
研究的目的:
- 研究结合tDCS和针对V1区域的神经导航rTMS在经历抑郁情绪发作的双相情感障碍患者的神经认知功能的疗效.
- 评估联合刺激对认知,情绪和安全结果的影响.
主要方法:
- 一项随机对照试验,涉及105名参与者,分为三个组:活跃的tDCS-活跃的rTMS,假的tDCS-活跃的rTMS和活跃的tDCS-假的rTMS.
- 一个为期3周的治疗方案,每周15次 (5次),包括tDCS,其次是神经导航rTMS.
- 在基线,治疗后和随访时使用THINC集成工具 (THINC-it),汉密尔顿抑郁症评分表和青年躁狂评分表评估认知功能和情绪状态.
主要成果:
- 与假装组相比,活跃的tDCS-活跃的rTMS组在3周后的符号检查 (时间和准确性) 和8周后的符号检查准确性显著改善.
- 活跃的tDCS-活跃rTMS和假的tDCS-活跃rTMS组都显示了从基线到3周的抑郁症状显著改善.
- 神经成像显示,在活跃的tDCS-活跃的rTMS组中,卡尔卡林的活性增加,这表明视觉皮层的神经可塑性变化.
结论:
- 导航式rTMS与针对V1区域的tDCS的组合显示了初步证据,作为治疗双相情感障碍认知障碍和抑郁症状的潜在治疗策略.
- 这种结合的NIBS方法可能为BD患者的复杂症状管理提供了一种新的治疗途径.

Rational Emotive Behavior Therapy

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Cognitive Therapy
144
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
