Previous studies could show a complex relationship between alcohol consumption and cognition but also with processes of ageing both social and biological. Acute effects of alcohol during intoxication include clinical signs such as excitation and reduced inhibition, slurred speech, and increased reaction time but also cognitive dysfunction, especially deficits in memory functions. However, these cognitive deficits during alcohol intoxication are reversible while patients with alcohol addiction and chronic alcohol intake show severe impairments of cognitive functions especially deficits in executive functions. Frontal executive impairments in these patients include deficits in problem solving, abstraction, planning, organizing, and working memory.Additionally, gender specific deficits are relevant for the course of the disease and its concomitant health problems with female alcoholics showing a higher vulnerability for cognitive dysfunction and brain atrophy at earlier stages of alcoholism history.
先前的研究表明,饮酒与认知之间存在复杂的关系,同时也与社会和生物衰老过程有关。酒精中毒期间酒精的急性影响包括兴奋、抑制作用减弱、言语不清、反应时间延长等临床症状,以及认知功能障碍,尤其是记忆功能缺陷。然而,酒精中毒期间的这些认知缺陷是可逆的,而酒精成瘾和长期饮酒的患者则表现出严重的认知功能损害,尤其是执行功能缺陷。这些患者的额叶执行功能损害包括解决问题、抽象思维、计划、组织和工作记忆方面的缺陷。此外,性别特异性缺陷与疾病进程及其伴随的健康问题相关,女性酗酒者在酗酒史的早期阶段表现出对认知功能障碍和脑萎缩的更高易感性。
