Psych: Korsakoff's Psychosis: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Korsakoff’s Psychosis🎧 A clear, high-yield breakdown of this profoundmemory disorder linked to thiamine deficiency – perfect for exam prep andreal-life clinical scenarios. 🧠Key Learning Points📌Definition• Korsakoff’sPsychosis is a chronic neurological disorder caused by severe deficiency ofthiamine (vitamin B1), classically following untreated Wernicke’sencephalopathy and most commonly seen in long-term alcohol misuse.📌Causes & RiskFactors• Chronic alcoholmisuse (most common)• Severemalnutrition (e.g., eating disorders, starvation)• Conditions causingpoor thiamine absorption (GI disorders, chronic vomiting, cancer, dialysis)• AIDS, severesystemic illness• 💡 Mnemonic: “A MALE DRAIN” – Alcohol, Malnutrition, Absorptionproblems, Liver disease, Elderly, Dialysis, Repeated vomiting, AIDS, Inadequate diet, Neurological risk📌Pathophysiology• Thiaminedeficiency impairs glucose metabolism, starving neurons of energy• Selective brainareas affected: mammillary bodies, thalamus, hypothalamus• Leads to celldeath, structural brain changes, and disruption of memory circuits📌Symptoms• Profoundanterograde amnesia (can’t form new memories)• Retrograde amnesia(loss of past memories)• Confabulation(unintentional filling of memory gaps with false stories)• Disorientation,poor attention, lack of insight, apathy• Residual signsfrom Wernicke’s: nystagmus, gait ataxia• Superficiallynormal social conversation despite severe amnesia• 💡 Mnemonic: “CAN’T REMEMBER” – Confabulation, Amnesia, Nystagmus, Thinking deficits, Retrograde loss, Encounter with alcohol, Memory fixation, Behavioural change, Executive dysfunction, Requires thiamine📌DifferentialDiagnosis• Alzheimer’sdisease, vascular dementia, other dementias• Traumatic braininjury• Hepaticencephalopathy• Delirium, alcoholwithdrawal• Drug intoxication,hypoxia, stroke, brain tumour📌Diagnosis• Clinical history:profound amnesia + confabulation in context of alcohol misuse or malnutrition•Cognitive/neuropsychological testing• Bloods: thiamine(may be normal), LFTs, FBC, rule out infection• MRI: cerebralatrophy, mammillary body changes, ventricular enlargement• Exclude othercauses with lumbar puncture or EEG if needed• 💡 Tip: Always suspect in confused, malnourished or chronic alcoholicpatients📌Management• Emergency: Immediate high-dose IV or IMthiamine – always before glucose• Long-term oralthiamine supplementation• Abstinence fromalcohol and treatment for dependence• Nutritionalsupport, multivitamins• Cognitiverehabilitation and long-term support for memory deficits• Multidisciplinarycare: doctors, nurses, psychologists, social workers• Legal safeguards(e.g., Mental Capacity Act) for severe cases📌Complications• Permanent, oftensevere, memory loss• Disability,long-term institutional care in 25%• Increased risk ofinfections, malnutrition, accidents• Recurrence ofWernicke’s encephalopathy if not treated or if alcohol misuse continues• Poor quality oflife, social isolation📌Prognosis• Early, aggressivethiamine treatment can prevent progression• EstablishedKorsakoff’s often causes permanent deficits—full recovery is rare• High risk ofrelapse and poor outcomes if underlying causes not addressed 📎More MSRA Resourcesfor Korsakoff’s Psychosis📝Revision Notes:https://www.passthemsra.com/topic/korsakoffs-psychosis-revision-notes/🧠Flashcards:https://www.passthemsra.com/topic/korsakoffs-psychosis-flashcards/💬Accordion Q&ANotes:https://www.passthemsra.com/topic/korsakoffs-psychosis-accordion-qa-notes/🚀Rapid Quiz:https://www.passthemsra.com/topic/korsakoffs-psychosis-rapid-quiz/🎓Full Course:https://www.passthemsra.com/courses/psychiatry-for-the-msra/#MSRA #MSRARevision#MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQANotes#MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision#MSRARevisionWebsite #KorsakoffsPsychosis
