Neuro: Frontotemporal Dementia: Free MSRA Podcast

🧠 FREE MSRA PODCAST – Frontotemporal Dementia (FTD): Behaviour, Language & the Younger BrainDive into the essentials of FTD—a vital, often-missed cause of early-onset dementia. This is your high-yield, exam-ready summary, made simple for revision and clinical practice.✨ Key Learning Points📌 Definition• FTD is a progressive neurodegenerative disorder• Targets the frontal & temporal lobes• Causes dramatic changes in behaviour, personality, executive function, & language• Memory loss is not the initial/main symptom—crucial for differentiating from Alzheimer’s📌 Classification• Not a single condition—FTD is a group of related syndromes: – Behavioural variant (BVFTD): Early personality/behavioural changes, disinhibition, loss of empathy, compulsions, apathy – Semantic dementia: Fluent speech but loss of meaning & vocabulary – Progressive non-fluent aphasia (PNFA): Effortful, halting speech, grammar errors• Overlap syndromes may involve Parkinsonism (PSP/CBS) or motor neurone disease (ALS)📌 Epidemiology & Risk• Second most common dementia under 65• Onset typically ~55 years (range: 45–65)• Prevalence: 15–22 per 100,000 (likely underestimated)• Up to 15% familial—autosomal dominant (MAPT, GRN, C9orf72 mutations)📌 Pathophysiology• Abnormal protein accumulations (tau, TDP-43, FUS) in frontal & temporal lobes• Leads to selective cell death, atrophy• Pathology classified by main protein (FTLD-tau, FTLD-TDP, FTLD-FUS)📌 Symptoms• Early: personality/behavioural change, language issues, executive dysfunction• Preserved memory in early disease• Disinhibition, loss of empathy, compulsivity, ritualistic behaviour• Food preference changes (↑ sweet cravings)• Parkinsonism in ~50%• Progresses to global cognitive & physical decline📌 Differential Diagnosis• Alzheimer’s (memory 1st), psychiatric disorders (depression, psychosis), Huntington’s, prion disease, vascular dementia, brain tumours, metabolic/nutritional/infectious/autoimmune causes📌 Diagnosis• Clinical assessment + collateral history• Neuropsychological testing: maps specific deficits• MRI: frontal/temporal atrophy• Bloods: rule out reversible causes (B12/folate, LFT, HIV, syphilis)• Consider genetics if family history• Functional imaging (FDG-PET/SPECT) may support diagnosis• CSF biomarkers (specialist use)• Diagnosis remains clinical; imaging supports but does not rule out FTD📌 Management• No cure—focus on symptoms & quality of life• Multidisciplinary team: speech therapy, OT, psychological support, social work• Early advance care planning, power of attorney• Medications for symptoms only: – SSRIs for compulsivity or mood – Antipsychotics with caution (↑ risks in dementia) – Manage Parkinsonism if present• Support for carers is essential (education, respite, psychological support)📌 Prognosis & Complications• Survival: average 6–10 years (semantic >10y, FTD+MND: 3–5y)• Progressive loss of independence, increased carer dependency• Risks: infections (esp. pneumonia), falls, challenging behaviour• Profound impact on families📎 More MSRA Resources for FTD📝 Revision Notes: https://www.passthemsra.com/topic/frontotemporal-dementia-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/frontotemporal-dementia-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/frontotemporal-dementia-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/frontotemporal-dementia-rapid-quiz/🧪 Quiz Bank: https://www.passthemsra.com/quizzes/frontotemporal-dementia/🎓 Neurology Course: https://www.passthemsra.com/courses/neurology-for-the-msra/#FrontotemporalDementia #FTD #NeurologyMSRA #MSRARevision #MSRAFlashcards #MSRAQandA #MSRAQuiz #PassTheMSRA #MSRAPodcast #YoungerOnsetDementia #TauProtein #TDP43 #BehaviouralNeurology
