Neuro: Delirium: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Acute Confusional State (Delirium)🎧 A high-yield breakdown of this acute mental status change – perfect for exam prep and real-life clinical practice.🧠 Key Learning Points📌 Definition• Delirium is a sudden, fluctuating disturbance in attention, awareness, and cognition – often described as an acute confusional state.📌 Causes & Risk Factors• Infections (UTI, pneumonia, sepsis)• Medications (anticholinergics, opioids, benzos)• Metabolic issues (hyponatraemia, hypoxia)• Surgery (especially emergency or major ops)• Alcohol/drug intoxication or withdrawal• Environmental changes (ICU, sensory deprivation)• Risk ↑ in: age >65, dementia, frailty, polypharmacy💡 Mnemonic: PINCHME – Pain, Infection, Nutrition, Constipation, Hydration, Medication, Electrolytes, Environment📌 Pathophysiology• Global brain dysfunction• Reduced acetylcholine, neurotransmitter imbalance• Neuroinflammation, oxidative stress• Impaired interconnectivity between brain regions📌 Symptoms• Sudden, fluctuating confusion• Impaired attention, disorientation• Sleep-wake cycle disturbance (e.g. sundowning)• Visual hallucinations, agitation (hyperactive) or lethargy (hypoactive)💡 Mnemonic: DELIRIUM – Disturbed attention, Emotional changes, Language disturbed, Illusions/hallucinations, Reversal of sleep, Inattention, Unawareness, Mixed/hyper/hypoactive subtypes📌 Differential Diagnosis• Dementia (chronic and progressive)• Depression, bipolar disorder• Schizophrenia• Metabolic encephalopathy• Stroke, brain tumour• Drug intoxication or withdrawal• Non-convulsive status epilepticus📌 Diagnosis• Clinical – acute onset, fluctuating course, inattention, and disorganised thinking• Cognitive test: 4AT• Collateral history crucial📌 Management• Treat underlying cause (e.g. infection, dehydration, drug withdrawal)• Optimize environment – calm, familiar, well-lit, sensory aids in place• Supportive care: hydration, nutrition, mobilisation, sleep hygiene• Antipsychotics (e.g. haloperidol) only if severely distressed• Avoid benzodiazepines unless alcohol/benzo withdrawal• Multidisciplinary approach essential📌 Complications• Falls and injuries• Prolonged hospital stay• Hospital-acquired infections• Functional decline and loss of independence• Increased risk of dementia• Higher mortality rate📌 Prognosis• Variable – depends on cause and patient frailty• Can resolve quickly if treated, but may persist or lead to long-term cognitive decline📎 More MSRA Resources for Acute Confusional State (Delirium)📝 Revision Notes: https://www.passthemsra.com/topic/acute-confusional-state-delirium-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/acute-confusional-state-delirium-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/acute-confusional-state-delirium-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/acute-confusional-state-delirium-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/neurology-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #AcuteConfusionalState #Delirium #NeurologyMSRA
