概括
患有双相情感障碍的患者表现出较短的端粒长度,表明加速衰老. 虽然这与较差的语言学习和记忆有关,但端粒长度对双相情感障碍认知功能的整体影响似乎有限.
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:
- 双极性障碍与加快的衰老过程有关,包括缩短端粒长度和认知功能受损.
- 在双相情感障碍中认知缺陷的神经生物学基础仍然不清楚.
- 由端粒长度表明的加速衰老可能与双相情感障碍患者的认知衰退相关.
研究的目的:
- 研究双相情感障碍患者的端粒长度与认知表现之间的关联.
- 确定缩短端粒长度是否作为加速衰老的标记,与特定的认知功能相关,特别是记忆和学习.
主要方法:
- 647名参与者 (246名患有双相情感障碍,401名健康对照) 进行了神经心理测试.
- 使用定量实时聚合酶链反应 (qPCR) 测量白细胞端粒长度,以确定端粒与单拷贝比率 (T/S比率).
- 对药物的控制分析,每日定义剂量 (DDD),时间年龄,性别和种族.
主要成果:
- 与健康对照组相比,双相情感障碍患者的端粒长度明显较短 (p=0.01).
- 在双相情感障碍患者的口头学习和端粒长度之间发现了积极的关联 (p=0.025).
- 观察到口头记忆和端粒长度 (p=0.07) 之间存在关联的趋势,没有发现其他显著的相关性.
结论:
- 双相情感障碍中端粒长度较短可能表明大脑健康状况较差,并且与语言学习减少有关.
- 端粒长度对双相情感障碍的整体认知功能的影响似乎有限.
- 需要进一步的研究,以充分阐明衰老,端粒长度和双相情感障碍的认知功能之间的复杂关系.

Bipolar Disorder
108
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
2.6K
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.

Mania and Antimanic Drugs: Overview
249
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Language and Cognition
376
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Long-term Potentiation

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

Negative and Cognitive Symptoms of Schizophrenia
96
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
