Alcohol consumption is a common practice worldwide and its effects on cognitive functioning have been studied extensively. Studies have shown that acute alcohol consumption can lead to impairments in various aspects of cognitive functioning, including attention, memory, decision-making and perception. The severity of these impairments is directly related to the Blood Alcohol Concentration (BAC) level. A total of 25 studies were selected based on their relevance to the topic and quality of evidence.
The relationship between BAC and cognitive functioning is well-established. Studies have shown that acute alcohol consumption can lead to impairments in various aspects of cognitive functioning, including attention, memory, decision-making and perception. The severity of these impairments is directly related to the BAC level. The following sections provide a brief summary of the findings from the selected studies.
At a BAC of 0.02%, individuals may experience mild exhilaration altered mood and reduced inhibitions. These efects can impact decision-making and may lead individuals to engage in risky behaviors. At 0.05%, there may be a slight impairment of coordination, judgment and reaction time. This level of BAC can lead to a decrease in cognitive flexibility and working memory, which can impact an individual’s ability to perform complex tasks.
At 0.08%, the legal limit for driving in many countries, the impairment of cognitive functioning becomes more significant. This level of BAC can lead to a decrease in attention, visual-spatial processing and executive functioning. Individuals may also experience impaired decision-making, which can lead to risky behaviors such as driving under the inluence [1-4].
Attention towards acute alcohol consumption
Acute alcohol consumption has been shown to impair attentional processes, including the ability to selectively attend to relevant information and filter out irrelevant information. Studies have demonstrated that this impairment is dose- dependent, with higher BAC levels leading to more significant attentional impairments. Additionally, the effects of alcohol on attentional processes may vary based on individual differences, such as gender and age.
Memory
Acute alcohol consumption has also been shown to impair memory processes, including both short-term and long-term memory. Studies have demonstrated that alcohol consumption can lead to impairments in the encoding, consolidation and retrieval of information. These effects are also BAC-dependent, with higher BAC levels leading to more significant memory impairments. Additionally, the effects of alcohol on memory may vary based on individual differences, such as genetic factors and previous alcohol exposure.
Decision making
Alcohol consumption has been shown to impair decision-making processes, including the ability to weigh the pros and cons of a decision and make a rational choice. Studies have demonstrated that alcohol consumption can lead to impulsive decision-making and a decreased ability to inhibit inappropriate responses. These effects are also BAC- dependent, with higher BAC levels leading to more significant impairments in decision-making processes.
Perception
Acute alcohol consumption can also impair perceptual processes, including the ability to process sensory information accurately. Studies have demonstrated that alcohol consumption can lead to impairments in visual and auditory perception, as well as spatial perception. These effects are also BAC-dependent, with higher BAC levels leading to more signiicant impairments in perceptual processes [5-7].
The relationship between BAC and impaired cognitive functioning is well-established. Acute alcohol consumption can lead to impairments in various aspects of cognitive functioning, including attention, memory, decision-making and perception. The severity of these impairments is directly related to the BAC level, with higher BAC levels leading to more significant impairments. Additionally, the effects of alcohol on cognitive functioning may vary based on individual differences, such as gender, age, genetic factors and previous alcohol exposure. These findings highlight the importance of responsible alcohol consumption and the need for public education programs to promote safe drinking practices.
