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.

Socio-Demographic and Clinical Characteristics of Patients with Substance Intoxication Receiving a Psychiatric Assessment in the Emergency Department of the Maggiore Della Carita Hospital, Novara, Italy.

Patients intoxicated with alcohol or other substances are often assessed and assisted in the context of the Emergency Department (ED) by emergency physicians, who usually require a psychiatric assessment. This study aims to analyse the characteristics of a sample of patients receiving a psychiatric consultation in the ED setting of the Maggiore della Carità University Hospital in Novara, Italy, in the period from 1 January 2021 to 31 December 2023, to find out whether and how patients screening positive for alcohol/drugs differ from those screening negative. Socio-demographic and clinical history information and clinical data related to the ED psychiatric consultations were extracted from the PsNet database, a collection of data extracted from the application that serves as the electronic medical record for patients accessing the ED.

Alcohol binge drinking has a multitude of effects on CNS function, including changes in inflammatory cytokines such as IL-6 and IL-1β that may contribute to mood fluctuations associated with the intoxication-withdrawal cycle. Widely throughout the brain, including the amygdala, IL-6 mRNA is enhanced during intoxication, whereas IL-1β is initially suppressed during alcohol intoxication, with increased expression seen shortly after ethanol clearance, during acute hangover. Furthermore, induction of neuroimmune genes appears to be muted during adolescence in the amygdala, suggesting a broader functional immaturity of the adolescent neuroimmune system in structures involved in negative affect associated with ethanol exposure.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.
