    Study Notes

    • The illness is characterized by insigent retrograde amnesia (memory loss for events before the onset of the illness).
    • Symptoms include:
      • Gloomy mood
      • Irritability
      • Difficulty copying complex figures
      • Impairment in executive functioning
    • These impairments are a result of alcohol abuse and resulting damage to the brain.
    • Alcohol can lead to a decline in performance on episodic memory tasks.
    • The decline in memory is due to impairment in encoding and storing new information.
    • Difficulty recalling memories correctly is a symptom often seen in individuals who consume alcohol.

    Proactive Interference

    • Proactive interference occurs when old memories interfere with the learning of new memories.
    • An example of proactive interference is an old story interfering with the ability to recall a new story.

    Retroactive Interference

    • Retroactive interference occurs when new memories interfere with retrieving old memories.
    • An example of retroactive interference is a new story interfering with the ability to recall an old story.

    Korsakoff's Syndrome

    • Korsakoff's syndrome is a severe form of alcohol-related amnesia characterized by difficulty recalling past events.
    • The syndrome is linked to a lack of thiamine (vitamin B1) caused by chronic alcohol abuse.
    • This lack of thiamine can damage the brain, leading to severe memory problems.

    Effects of Alcohol Abuse

    • Alcohol abuse and related cognitive disorders can affect the brain's volume.
    • This volume loss can affect the frontal lobe, which is important for complex thinking and decision-making.
    • Alcohol can also damage the diencephalon, which is responsible for memory formation.
    • Alcoholic encephalopathy is a brain disorder that can occur due to chronic alcohol abuse.
    • This can lead to problems with memory, thinking, and behavior.

    Alcohol & Cognitive Impairment

    • Adults who have already experienced cognitive impairment are at higher risk for further impairment from alcohol use.
    • Individuals with alcohol use disorder are at a higher risk of experiencing cognitive problems.
    • Studies have shown that alcohol consumption accelerates cognitive decline in individuals with existing cognitive impairments.

    The Effects of Alcohol on the Adolescent Brain

    • Adolescents who consume alcohol have lower volumes of gray and white matter compared to non-drinkers.
    • This reduction in brain matter is observed in specific brain regions, including those involved in learning and memory.
    • The effects of alcohol on adolescent brains are more pronounced in older adolescent cohorts.

    Study Limitations

    • There is a lack of information on socio-economic status (SES) and its impact on alcohol use and cognitive function.
    • The study did not include cognitive tasks or magnetic resonance imaging (MRI) assessments, limiting the analysis of cognitive functions and brain structures.
    • Sample sizes in the research were small.
    • There was a lack of information on other drug use and a heterogeneous population, making it difficult to draw definitive conclusions about the specific effects of alcohol on cognition.
    • Findings from this study cannot establish a clear causal relationship between alcohol use and cognitive impairment, or determine a dose-response relationship.
