Psych: Wernicke's Encephalopathy: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Wernicke’s Encephalopathy🎯 In this Deep Dive, we break down everything youneed to know for the MSRA on Wernicke’s Encephalopathy —from core pathology to clinical red flags, investigations, management, andcomplications. ✅ High-yield revision ✅ Exam-focused ✅Real-world clinical pearls. 🧠Key Learning Points📌Definition &Urgency• Acute neurologicalemergency caused by thiamine (vitamin B1)deficiency• If untreated →rapid progression to Korsakoff syndrome• Always consider inconfused, malnourished or alcohol-dependent patients📌Causes & RiskFactors• Chronic alcoholism (most common) 🍺• Malnutrition &starvation•Hyperemesis gravidarum (severe vomiting in pregnancy) 🤰• GI malabsorption(e.g. Crohn’s, bariatric surgery)• Eating disorders(e.g. anorexia nervosa)• Long-term TPNwithout thiamine• Dialysis, AIDS,certain malignancies💡Mnemonic: “Malnourished ALCOHOLICS Vomit Thiamine”📌Pathophysiology• Thiamine essentialfor brain energy metabolism• Deficiency →metabolic failure in thalamus, mammillarybodies, brainstem• Energy crisis →neuronal damage, oxidative stress, cell death💡Mnemonic: “Brain cells need B1”📌Classic ClinicalTriad (but rarely all present):1️⃣ Confusion (most common)2️⃣ Ataxia (gait/balance problems)3️⃣ Ophthalmoplegia (eye movement problems: nystagmus,diplopia)Additional: memory loss, confabulation, hypotension, hypothermia, cachexia💡 Mnemonic: “CAN – Confusion, Ataxia, Nystagmus”📌Progression toKorsakoff Syndrome• Chronic amnesia(anterograde + retrograde)• Confabulation• Poor prognosis ifuntreated• Up to 85% progress to Korsakoff’s if Wernicke’suntreated💡Key stat: Only ~20% fully recover from establishedKorsakoff’s.📌Investigations•Primarily a clinicaldiagnosis ⚠️• Bloods: FBC,U&Es, LFTs, glucose, B12, folate• MRI: changes inmammillary bodies, thalamus (more sensitive than CT)• LP (if CNSinfection needs exclusion)• Thiamine levelsnot reliable — treat without waiting!📌Management• Immediate IV thiamine replacement — high dose• Start BEFOREglucose to avoid precipitating Wernicke’s• Long-term oralthiamine + nutritional support• Manage underlyingcause (alcohol cessation, eating disorder support)• MDT input:dieticians, alcohol team, social workers, mental health services💡Key rule: “Suspect = Treat ASAP”📌Prognosis• Early treatment =reversible confusion & eye signs• Ataxia may persist• Untreated:Up to 20% mortality ☠️85% develop Korsakoff’s25% may need long-term institutional care📌Complications• Korsakoff’ssyndrome• Chronic memoryimpairment• Persistent gaitdisturbance• CHF (wet beriberilink)• Alcohol withdrawal& medical comorbidities📌Prevention• Prophylactic thiamine in high-risk patients(alcoholics, malnourished)• Earlyidentification in hospital admissions• Holistic care forvulnerable groups (homelessness, eating disorders, older adults) 📎More MSRA Resourcesfor Wernicke’s Encephalopathy📝 Revision Notes:https://www.passthemsra.com/topic/wernickes-encephalopathy-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/wernickes-encephalopathy-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/wernickes-encephalopathy-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/wernickes-encephalopathy-rapid-quiz/🧪 Extra Quiz:https://www.passthemsra.com/quizzes/wernickes-encephalopathy/🎓 Psychiatry MSRA Course:https://www.passthemsra.com/courses/psychiatry-for-the-msra/ #MSRA#MSRARevisionNotes #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards#MSRAQANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment#MSRAOnlineRevision #MSRARevisionWebsite #Psychiatry #WernickesEncephalopathy
