概括
患有酒精使用障碍 (AUD) 的个人表现出加速的大脑衰老,较高的大脑年龄与较差的执行功能有关. 这种加速的大脑衰老可能表明AUD患者的大脑健康受到损害.
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.
- 放射学 放射学是一门学科.
背景情况:
- 大脑年龄是神经认知功能和大脑健康的新生物标志物.
- 以前的研究表明,在酒精使用障碍 (AUD) 中,大脑过早衰老.
- 在AUD中具体量化大脑年龄的研究是有限的.
研究的目的:
- 用大脑形态特征估计AUD患者的大脑年龄.
- 在AUD中探索大脑年龄与神经认知性能,冲动性和酒精消费之间的关系.
主要方法:
- 利用大脑形态特征 (皮层厚度,大脑体积) 来计算大脑年龄.
- 采用了一个XGBoost回归模型,具有187个预测器.
- 包括30名禁酒的成年男性有AUD病史和30名男性对照.
主要成果:
- 患有AUD的个体的平均大脑年龄比他们的时间年龄大1.70年.
- 在AUD组中,较高的大脑年龄与执行功能受损相关.
- 较大的大脑年龄差距与较低的非计划冲动性和较晚开始定期饮酒有关.
结论:
- AUD与加速的大脑衰老有关,这表明大脑健康的潜在妥协.
- 大脑年龄的测量与神经认知,冲动和酒精消费模式相关.
- 结果可能会为早期识别,预防和AUD治疗策略提供信息,这需要在更大的队列中进行进一步调查.

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...

CNS Depressants: Alcohol and Nicotine
1.0K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
