Neuro: Parkinson's Disease: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Parkinson’s Disease🎧 A clear, high-yield breakdown of this progressive movement disorder – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Chronic, progressive neurodegenerative condition affecting movement.• Caused by dopamine neuron loss in the substantia nigra.📌 Causes & Risk Factors• Largely idiopathic (unknown cause)• Genetic mutations (e.g. LRRK2, GBA)• Environmental toxins (e.g. pesticides)• Age (risk ↑ with age)• Male sex (2:1 ratio)🧠 Mnemonic: "GEM-Age" = Genetics, Environment, Male, Age📌 Pathophysiology• Dopamine-producing neurons degenerate in substantia nigra• ↓ Dopamine → dysfunction in basal ganglia motor circuits• Leads to motor control issues📌 Symptoms• Motor: Tremor (resting), Rigidity, Akinesia/Bradykinesia, Postural Instability• Non-motor: Hyposmia, constipation, REM sleep disorder, depression, cognitive decline🧠 Mnemonic: TRAP = Tremor, Rigidity, Akinesia, Postural instability📌 Differential Diagnosis• Essential tremor• Drug-induced Parkinsonism• Progressive supranuclear palsy• Multiple system atrophy• Lewy body dementia📌 Diagnosis• Clinical diagnosis: bradykinesia + 1 other TRAP feature• DAT scan (SPECT): ↓ dopamine uptake• MRI: To rule out mimics🧠 Tip: DAT scan helps differentiate from essential tremor📌 Management• Levodopa (gold standard)• Dopamine agonists (e.g. ropinirole)• MAO-B inhibitors (e.g. selegiline)• COMT inhibitors, amantadine, anticholinergics• Advanced options: Apomorphine pump, Duodopa, Deep Brain Stimulation (DBS)• MDT input: physio, OT, SLT, PD nurse🧠 NICE: Offer levodopa if motor symptoms affect life📌 Complications• Motor fluctuations, dyskinesias• Falls, aspiration pneumonia• Dementia, hallucinations• Parkinson’s crisis (acute akinesia)• Autonomic dysfunction (hypotension, constipation)📌 Prognosis• Variable but progressive• Life expectancy may be slightly reduced• Quality of life can be maintained for many years with good MDT care📎 More MSRA Resources for Parkinson’s Disease📝 Revision Notes: https://www.passthemsra.com/topic/parkinsons-disease-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/parkinsons-disease-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/parkinsons-disease-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/parkinsons-disease-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/neurology-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #ParkinsonsDisease
