Neuro: Normal Pressure Hydrocephalus: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Normal Pressure Hydrocephalus (NPH)🎧 A clear, high-yield breakdown of this reversible cause of dementia with classic triad – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• A neurological disorder involving ventricular enlargement due to impaired CSF absorption, but with normal average pressure• Causes the classic triad: gait disturbance, cognitive decline, and urinary incontinence📌 Causes & Risk Factors• Idiopathic NPH – most common, seen in older adults• Secondary NPH – due to:– Subarachnoid haemorrhage– Meningitis– Head injury– Brain tumours• Risk factors: Age >60, prior brain surgery, trauma, infection💡 Mnemonic: “Worn PATH” – Women/Men equally, Over 60, Radiation/surgery, Neuro infections, Post-SAH, Ageing, Trauma, Head injury📌 Pathophysiology• CSF absorption is reduced (not overproduced), leading to ventricular dilation• Pressure on nearby brain tissue disrupts gait, cognition, and bladder control📌 Symptoms• Gait disturbance – slow, wide-based, shuffling (first to appear)• Urinary symptoms – urgency → incontinence• Cognitive decline – executive dysfunction, bradyphrenia, disorientation💡 Mnemonic: “Wet, Wobbly, Wacky”📌 Differential Diagnosis• Alzheimer’s disease• Parkinson’s disease• Vascular dementia• Frontotemporal dementia• Multiple system atrophy📌 Diagnosis• MRI or CT – shows ventriculomegaly, possibly DESH pattern• CSF Tap Test – temporary symptom improvement after lumbar puncture• ICP monitoring, lumbar infusion tests for unclear cases💡 Tip: No papilloedema helps distinguish from raised ICP hydrocephalus📌 Management• Ventriculoperitoneal (VP) shunt – definitive treatment• Alternative: ventriculoatrial shunt• Rehabilitation post-op is crucial (gait training, physio)• Medical options (e.g. acetazolamide) have limited benefit• Repeated LP – temporary relief only🎯 Early diagnosis → better prognosis📌 Complications• Shunt malfunction or blockage• Infection• Overdrainage → subdural haematomas, low-pressure headaches• Underdrainage, catheter migration, general surgery risks📌 Prognosis• 80–90% show improvement post-shunting• Best outcomes if treated early (within 3 months of symptom onset)• Gait often improves most; cognitive and bladder function may also recover• ~6% risk of long-term complications, ~22% may need revision surgery📎 More MSRA Resources for Normal Pressure Hydrocephalus📝 Revision Notes: https://www.passthemsra.com/topic/normal-pressure-hydrocephalus-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/normal-pressure-hydrocephalus-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/normal-pressure-hydrocephalus-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/normal-pressure-hydrocephalus-rapid-quiz/🧪 Quiz Bank: https://www.passthemsra.com/quizzes/normal-pressure-hydrocephalus/🎓 Full Course: https://www.passthemsra.com/courses/neurology-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQANotes #MSRAAccordions #MSRAOnlineRevision #MultiSpecialityRecruitmentAssessment #NormalPressureHydrocephalus #NPH #NeurologyMSRA #WetWobblyWacky #ReversibleDementia
