Neuro: Essential Tremor: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Essential Tremor🎧 A clear, high-yield breakdown of this commonmovement disorder – perfect for exam prep and real-life clinical scenarios. 🧠Key Learning Points📌Definition• Essential Tremor(ET) is a chronic, progressive neurologicaldisorder that causes involuntary,rhythmic shaking, typically affecting the hands during action or posture holding (not at rest). 📌Causes & RiskFactors• Idiopathic in most cases• Autosomal dominant inheritance (~50% familial)• Increasing age (more common >40)• Triggers: caffeine, stress, fatigue, some medications• Environmentalfactors (e.g. toxins) may contribute🧠Mnemonic:“G.A.S.T.E.” – Genetics, Age, Stimulants, Toxins, Essential cause unknown 📌Pathophysiology• Dysfunction in thecerebellar-thalamic pathway• Involves abnormal GABAergic signalling• Faulty brain circuitry → tremor signals duringmovement 📌Symptoms• Bilateral action tremor of the hands• Worsens with movement, stress, or posture holding• May affect: head (nodding/"no-no"), voice (shaky speech), sometimes legs• Improvestemporarily with alcohol🧠Mnemonic:“T.R.E.M.O.R.” – Tremor with movement, Rhythmic, Enhanced by stress, Mostlyhands, Occasional voice/head, Relieved by alcohol 📌DifferentialDiagnosis• Parkinson’s Disease (resting tremor,bradykinesia, rigidity)• Drug-induced tremor (e.g. lithium, SSRIs)• Cerebellar tremor (intention tremor)• Dystonic or psychogenic tremor• Hyperthyroidism• Physiological tremor (anxiety, caffeine) 📌Diagnosis• Clinical diagnosis – detailed history +neurological exam• No specific test for ET• Bloods: TFTs, LFTs,copper (Wilson’s), FBC, U&Es• Imaging (MRI) if atypical signs or rapid progression🧠TIP: Tremor duringaction = ET; Tremor at rest = Parkinson’s 📌Management• 🧘‍♀️ Lifestyle: avoid triggers (stress, caffeine), OT input• 💊 First-line meds: Propranolol, Primidone• 💉 Botulinum toxin: for head/voice tremor• 🧠 Advanced options: – Deep Brain Stimulation (DBS) – MRI-guided Focused Ultrasound (MRgFUS)• Consider occupational support, psychological support if needed✅ NICE advises DBS for severe refractory cases 📌Complications• 🖐️ Difficulty with writing, eating, drinking• 💼 Occupational impairment• 😓 Social embarrassment, anxiety• 📉 Reduced quality of life• ⚠️Progressive loss of independence in severe cases 📌Prognosis• ⏳ Chronic, slowly progressive but notlife-threatening• Life expectancy = normal, but symptomsmay worsen over decades• Early onset =typically slower progression• Treatment improvesfunction but does not halt progression 📎More MSRA Resourcesfor Essential Tremor📝Revision Notes:https://www.passthemsra.com/topic/essential-tremor-revision-notes/🧠Flashcards:https://www.passthemsra.com/topic/essential-tremor-flashcards/💬Accordion Q&ANotes:https://www.passthemsra.com/topic/essential-tremor-accordion-qa-notes/🚀Rapid Quiz:https://www.passthemsra.com/topic/essential-tremor-rapid-quiz/🎓Full Course –Neurology for the MSRA:https://www.passthemsra.com/courses/neurology-for-the-msra/ #MSRA #MSRARevision#MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes#MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision#MSRARevisionWebsite #EssentialTremor #Neurology
