- 成研究 研究成研究
背景情况:
- 过度饮酒 (BD) 是学生中普遍存在的饮酒模式.
- 以前的研究将BD与改变的静止状态功能连接 (RS-FC) 联系起来,但在发育过程中长期的影响还未得到充分研究.
研究的目的:
- 在大学生中研究持续BD对RS-FC的中长期影响,持续两年.
- 为了确定在关键的神经发育时期与持续的BD相关的特定大脑网络变化.
主要方法:
- 一项为期两年的纵向fMRI研究,涉及44名大学生 (16名暴饮酒者).
- 采用种子到声音的方法来检查RS-FC在已知易受酒精滥用影响的大脑网络中的差异.
- 在18-19岁和20-21岁进行了两次fMRI会议.
主要成果:
- 与第二次评估中的对照人群相比,狂饮者在执行控制,突出性和情绪网络中的连接性下降.
- 具体来说,观察到右SFG和右前中心,ACC和右后中心,以及左桃体和中间前部/背部ACC之间的连接性减少.
- 在过度饮酒者的奖励网络 (右NACC) 中发现了增加的连接性,连接到额头和带带肌区域.
结论:
- 在青春期和早期成年期持续的BD导致功能性大脑组织的中长期变化.
- 研究结果强调了青少年滥用酒精对大脑功能连接的神经毒性影响.

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

01:27CNS Depressants: Alcohol and Nicotine
170
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...

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
