概括
端粒缩短与双相情感障碍 (BD) 易感性有关. 在BD-I和BD-II患者中观察到较短的端粒,在BD-II患者中,端粒长度预测了工作记忆.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 遗传学 是一个
- 精神病学是一个精神病学.
背景情况:
- 端粒缩短是精神疾病中衰老和疾病易感性的潜在生物标志物.
- 端粒长度和双相情感障碍 (BD) 之间的关联仍然不清楚.
- 端粒缩短在BD患者认知障碍中的作用是不确定的.
研究的目的:
- 调查双极性障碍 (BD-I和BD-II) 患者的端粒长度和认知功能.
- 探索BD患者的端粒长度和认知表现之间的关系.
- 确定端粒缩短是否是BD认知障碍的一个独立因素.
主要方法:
- 招募了三组患者:舒缓性BD-I患者 (n=35),舒缓性BD-II患者 (n=18) 和健康对照 (n=38).
- 使用光定量聚合酶链反应 (q-PCR) 测量端粒长度.
- 通过 MATRICS 共识认知电池 (MCCB) 评估认知功能,并使用 SPSS 24.0.0 分析数据.
主要成果:
- 与健康对照组相比,Euthymic BD-I和BD-II患者表现出较短的端粒长度 (P=0.001).
- 在BD-I和BD-II组之间没有发现端粒长度的显著差异.
- 与对照组相比,BD-I患者的注意力和警觉表现较差 (P=0.036).
- 在BD-II患者中,工作记忆与端粒长度正相关 (P=0.041).
结论:
- 优性BD患者的端粒长度缩短表明它可能是BD易感性的生物标志物.
- 端粒长度是BD-II患者工作记忆的预测指标.
- 需要进一步的研究,以了解加速衰老对年轻BD患者认知功能的影响.

Bipolar Disorder
67
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Long-term Depression
2.5K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
