概括
滥用酒精会损害白质 (WM) 的完整性,影响认知功能. 分数异构 (FA) 可能作为酒精使用障碍 (AUD) 中大脑损伤的生物标志物.
科学领域:
- 神经成像是一种神经成像.
- 神经科学是一个神经科学.
- 成研究 研究成研究
背景情况:
- 酒精使用障碍 (AUD) 是一个全球性的健康问题,已知对大脑结构有不利影响.
- 滥用酒精特别损害白质 (WM) 纤维通道,这对认知和情绪处理至关重要.
- 现有的研究往往缺乏对这些WM变化及其临床相关性的系统分析.
研究的目的:
- 系统地评估酒精使用障碍 (AUD) 患者的结构白质 (WM) 变化.
- 调查AUD患者白质完整性和临床症状之间的相关性.
- 为了确定潜在的神经成像生物标志物来评估酒精诱导的大脑损伤.
主要方法:
- 扩散张力成像 (DTI) 数据从20名AUD患者和20名健康对照获得.
- 基于管道的空间统计 (TBSS) 用于分析白质完整性,特别是分数异构性 (FA) 值.
- 研究了FA值与认知功能障碍,抑郁和冲动性的临床测量之间的相关性.
主要成果:
- AUD患者在关键大脑区域显著降低了FA值,包括右体,右,左下额头带和左脑白质.
- 在右和左脑白质中的FA值与AUD组的认知功能得分有显著的正相关性.
- 在控制了吸烟状况,年龄和教育等潜在混因素后,这些相关性仍然显著.
结论:
- 滥用酒精导致白质完整性的显著损害,特别是影响参与认知和情绪调节的区域.
- 这些发现提供了神经生物学证据,支持AUD对大脑的结构影响.

366
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...

01:26Alzheimer's Disease: Overview
675
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...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
