    Study Notes

    Wernicke-Korsakoff Syndrome

    • Characterized by confusion, ataxia, and ophthalmoplegia
    • Often caused by alcohol abuse and thiamine deficiency
    • Can present with symptoms such as confusion, delirium, ataxia and eye movement problems including nystagmus and opthalmoplegia
    • Infections like respiratory infections, UTIs, abdominal infections, sepsis, and meningitis can also be causes
    • Reversible in acute stage
    • Treatment involves abstinence and vitamin B1 supplementation
    • Chronic alcohol use leads to brain damage, primarily in the diencephalon, including mammillary bodies and thalamus
    • Can lead to profound amnesia, confabulation, and other cognitive impairments

    Korsakoff’s Syndrome: Interferences and Temporal Gradient

    • Proactive interference: New memories are interfered with by old memories
    • Retroactive interference: Old memories are interfered with by new memories
    • Patients show a temporal gradient in memory, where memories from further in the past are better preserved than more recent memories

    Korsakoff’s Syndrome: Autobiographical Memory

    • Researchers have studied the effects of alcohol use on autobiographical memory using the Galton-Crovitz method
    • The Galton-Crovitz method involves presenting subjects with cue words and asking them to recall memories associated with the words
    • Studies suggest that alcohol use can have an impact on autobiographical memory, particularly in individuals with Korsakoff's syndrome and other alcohol-related disorders
    • More longitudinal research is needed to confirm the impact of alcohol use on autobiographical memory, taking into account the potential confounding effects of sociodemographic factors

    Alcohol's Impact on Brain and Cognitive Function

    • Alcohol mimics GABA, a major brain inhibitor
    • Effects of alcohol on the brain are dose-dependent:
      • Small amounts impact frontal lobes, leading todecreased thinking and analytical abilities
      • Larger amounts affect the cerebellum, leading to motor skill impairment
      • Excessive amounts affect the brainstem, potentially resulting in coma
    • Chronic alcohol use leads to brain volume loss, especially in the frontal lobes, and can affect cerebrospinal fluid in areas of tissue loss
    • Chronic alcohol abuse can lead to alcoholic encephalopathy, an abnormal brain condition
    • Alcoholic encephalopathy can manifest as cognitive impairments like executive dysfunction and social cognition deficits, as well as difficulties with working memory and episodic memory
    • Individuals with alcohol use disorders often experience cognitive problems
    • Individuals with older adults with preexisting cognitive impairment may experience faster decline in cognitive function if they also engage in alcohol use
    • Uncomplicated patients often experience good recovery, particularly in their episodic memory
    • Contextual confusion (associating information with the wrong time and place) and increased proactive interference can occur, and these can be assessed using various memory tests
    • The Rivermead Behavioural Memory Test (RBMT-3) is a valuable ecologically valid test for assessing episodic memory
