概括

背侧前额皮层 (DLPFC) 刺激减少了无症症状. 双边刺激显示出更大的效果,基线α不对称性预测了抑郁症中无情感的治疗反应.

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.
临床神经生理学临床神经生理学

背景情况:

无情,主要抑郁症 (MDD) 的一个关键症状,意味着愉悦能力下降.
电脑电图 (EEG) 中的α不对称性与MDD和无情有关,这表明它有可能作为生物标志物.
背侧前额皮层 (DLPFC) 刺激是一种非侵入性神经调节技术,用于治疗抑郁症.

研究的目的:

调查双边 (BS) 和单边 (US) DLPFC刺激对前置和后置EEGα不对称 (FAA和PAA) 的影响.
评估DLPFC刺激对缓解无症症状的有效性.
探索基线α不对称性模式与无症治疗结果之间的关系.

主要方法:

一项探索性研究涉及61名患有无情感的参与者,随机分配到DLPFC的假冒,BS或US.
使用Snaith-Hamilton快乐量表 (SHAPS) 测量了无情感症状.
计算了前部和后部EEGα不对称性 (FAA和PAA),以及α峰值频率.

主要成果:

与假刺激相比,DLPFC的BS和US都显著降低了无症症状.
基线PAA是治疗后无情和抑郁症状的显著预测因素.
基线α不对称的特定模式 (BS的右侧FAA/PAA,US的左侧FAA或右侧PAA) 预测了无减少.

结论:

在患有抑郁症的人中,DLPFC刺激,特别是双边刺激,可以有效地减少无情症的症状.
基线EEGα不对称性,特别是PAA,可以预测DLPFC刺激的治疗反应.
这些发现支持阿尔法不对称性在无虫病理生理学中的作用,并强调其作为针对性神经调节疗法的生物标志物的潜力.

G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Depressive Disorders: MDD and Dysthymia

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...
