概括
患有双相情感障碍 (BD) 的老年人认知障碍往往不是由于痴呆症. 较低的粉样蛋白β42水平可能会导致BD相关的认知问题,这表明改变的粉样蛋白代谢起着作用.
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.
- 老年学是指老年学的学科.
背景情况:
- 认知障碍在双相情感障碍 (BD) 中很常见,痴呆的患病率很高.
- 在BD中认知缺陷的潜在病理生理学仍然不清楚.
- 神经退行可能导致老年BD (OABD) 患者的认知投诉.
研究的目的:
- 调查OABD患者认知投诉的原因.
- 要区分痴呆症和内在的BD相关的认知障碍.
- 探索神经退行生物标志物与OABD认知功能之间的关系.
主要方法:
- 来自阿姆斯特丹痴呆症队伍的102名OABD患者接受了临床,神经心理,CSF生物标志物和MRI评估.
- 神经学诊断被确定为认知投诉的主要原因.
- 在没有神经学诊断的患者中,线性回归分析了CSF生物标志物 (Aβ42,T-Tau,P-Tau) 和认知评分之间的关联.
主要成果:
- 在28.4%的OABD患者中确立了神经学诊断,包括6例阿尔茨海默病.
- 在剩下的71.6%的患者中,较低的CSF Aβ42度与较差的认知评分相关.
- 脑液T-Tau,P-Tau和MRI标志物与认知评分没有显著的关联.
结论:
- 大多数OABD患者在记忆诊所提出认知投诉,但没有得到特定的神经诊断.
- 改变的粉样蛋白代谢,由较低的CSF Aβ42表明,可能是BD相关认知障碍的促成因素.
- 未来的研究应该研究更广泛的生物标志物,包括粉样蛋白,与BD中的认知有关.

Bipolar Disorder
602
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.

Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
