📌 Causes & Risk Factors
• Autosomal dominant CAG repeat expansion in HTT gene
• Family history (50% inheritance risk)
• Anticipation – earlier/more severe in successive generations

📌 Pathophysiology
• Mutant Huntington protein → toxic buildup in neurons
• Neuronal death, especially in basal ganglia (striatum)
• Affects GABAergic and cholinergic neurons

📌 Symptoms
• Motor: chorea, dystonia, bradykinesia
• Cognitive: memory loss, poor planning, dementia
• Psychiatric: depression, irritability, psychosis
• Juvenile HD: learning issues, rigidity, seizures

📌 Differential Diagnosis
• Parkinson’s, Alzheimer’s, ataxias
• Wilson’s disease, schizophrenia, functional disorders

📌 Diagnosis
• Genetic test (HTT gene CAG repeat count)
• MRI: caudate atrophy
• Neuropsychological assessment
• Genetic counselling before/after testing

📌 Management
• Symptom-based: tetrabenazine (chorea), SSRIs, antipsychotics
• MDT: neurologist, psychiatry, physio, OT, SALT
• Advanced: DBS (rare), feeding support
• Palliative planning, support for carers

📌 Complications
• Aspiration pneumonia
• Falls, malnutrition
• Severe dementia, suicide risk
• Functional decline

📌 Prognosis
• Onset 30–50 years; survival ~15–20 years post-onset
• Disease progression varies; earlier onset = faster decline

⚕️ FREE MSRA PODCAST – Horner’s Syndrome
🎧 A clear, high-yield breakdown of this sympathetic nerve disorder affecting the eye and face – perfect for exam prep and clinical recognition.

🧠 Key Learning Points

📌 Definition
• A rare neurological condition caused by disruption of the sympathetic nerves supplying the face and eye
• Classic triad: ptosis, miosis, and anhidrosis on the same side of the face

📌 Causes & Risk Factors
• Central (1st-order neuron): stroke, MS, brainstem tumour
• Preganglionic (2nd-order): Pancoast tumour, cervical rib, trauma, surgery
• Postganglionic (3rd-order): carotid artery dissection, cluster headaches, herpes zoster, trauma
• Congenital (with heterochromia iridis)
💡 Mnemonic: PAM is Horny → Ptosis, Anhidrosis, Miosis

📌 Pathophysiology
• Disruption of the three-neuron sympathetic pathway from the hypothalamus → spinal cord (C8–T2) → cervical sympathetic chain → carotid artery → orbit
• Loss of sympathetic input results in:
– ↓ upper eyelid tone (ptosis)
– Unopposed parasympathetic tone → constricted pupil (miosis)
– Loss of facial sweating (anhidrosis)

📌 Symptoms
• Partial ptosis – drooping of upper eyelid
• Miosis – small pupil, worsened in darkness
• Anhidrosis – lack of sweating on the affected side
• ± Apparent enophthalmos, heterochromia (if congenital)

📌 Differential Diagnosis
• 3rd nerve palsy – also has ptosis, but causes dilated pupil
• Cluster headache – may mimic or cause Horner’s
• Ophthalmoplegic migraine
• Other causes of anisocoria or facial asymmetry

📌 Diagnosis
• Clinical exam: classic triad, anisocoria more obvious in dim light
• Pharmacological tests:
– Apraclonidine: reverses anisocoria (dilates Horner’s pupil)
– Hydroxyamphetamine 1%: localises the lesion
• Imaging depends on lesion location:
– Central: MRI brain/spinal cord
– Preganglionic: CXR, CT chest/neck
– Postganglionic: Carotid Doppler, MRI/MRA head/neck/orbits, CTA
💡 Use anatomy to guide investigations

📌 Management
• Treat the underlying cause
– Tumour → surgery or oncology
– Stroke → secondary prevention
– Carotid dissection → urgent vascular referral ± anticoagulation
• Symptomatic treatment rarely needed
• Multidisciplinary referrals: neurology, vascular surgery, ENT, oncology as needed

📌 Complications
• Horner’s itself is not dangerous
• Complications depend on cause: stroke, tumour growth, arterial rupture, etc.

📌 Prognosis
• Depends entirely on treatability of the underlying cause
• Symptoms may resolve if cause is reversible; may persist otherwise
• Congenital cases often lifelong but benign

🦠 FREE MSRA PODCAST – Herpes Simplex Encephalitis: Spotting the Silent Killer Early

🎧 A clear, rapid-fire guide to the UK’s most important cause of viral encephalitis—what you must know for the exam, and to save lives on the wards.

🧠 Key Learning Points

📌 Definition
• Herpes simplex encephalitis (HSE) = acute, life-threatening viral infection of the brain, usually due to HSV-1 (95% adults/children)
• Leads to brain inflammation, rapid neurological decline, and permanent disability/death if not treated promptly

📌 Causes & Risk Factors
• HSV-1 reactivation (often after cold sores), travels along nerve pathways to brain (esp. temporal/frontal lobes)
• HSV-2 mainly in neonates (acquired during birth)
• Higher risk: immunocompromised, previous herpes infection, extremes of age, genetic factors

📌 Pathophysiology
• Virus enters CNS → direct neuronal injury + intense immune response → brain swelling, cell death
• Classic sites: medial temporal & inferior frontal lobes

📌 Differential Diagnosis
• Other viral/bacterial encephalitis, autoimmune encephalitis, meningitis, brain abscess, cerebral vasculitis, SLE, stroke, tumours, MS, syphilis

📌 Epidemiology
• Rare: ~1 in 250,000/year UK
• Any age, but peaks in childhood & older adults
• Most common cause of sporadic, severe encephalitis

📌 Symptoms
• Acute onset fever, headache, confusion, personality/behaviour change
• Seizures (very common), focal neurology (e.g. weakness, aphasia), altered consciousness/coma
• Neonatal: lethargy, seizures, poor feeding, bulging fontanelle, shock, rash

📌 Diagnosis
• CSF (lumbar puncture): lymphocytosis, raised protein
• PCR for HSV DNA on CSF = gold standard
• MRI: temporal/inferior frontal lobe changes
• EEG: diffuse slowing, periodic discharges (can help early)
• Rule out mimics: FBC, blood cultures, renal/liver tests

📌 Management
• Immediate IV aciclovir (do not wait for confirmation if suspected!)
• Admit to hospital; monitor neurology, fluids, electrolytes
• Manage seizures aggressively (anticonvulsants as needed)
• Supportive care: fluids, airway, ventilation if needed
• Consider IV antibiotics initially to cover bacterial meningitis until excluded
• Steroids: role uncertain—usually not first-line

📌 Complications
• High risk of permanent neurological deficits—memory loss, seizures, behavioural change, cognitive impairment
• Death if untreated (~70–80%); with treatment ~10–20% mortality
• Chronic epilepsy, recurrent encephalitis, neuropsychiatric sequelae, dependency

📌 Prognosis
• Time is brain! Early aciclovir is crucial
• Many survivors have lasting problems despite optimal treatment
• Poorer outcome: older age, immunosuppression, coma, ventilation, thrombocytopenia

⚡ FREE MSRA PODCAST – Guillain-Barré Syndrome (GBS): Ascending Weakness, Rapid Recovery?

🎧 Your rapid-fire, high-yield guide to GBS—covering everything from triggers and clinical pearls to exam pitfalls and management essentials.

🧠 Key Learning Points

📌 Definition
• Guillain-Barré Syndrome (GBS) = acute, autoimmune, demyelinating polyneuropathy
• Characterised by rapid-onset, progressive muscle weakness
• Often follows infection (especially Campylobacter jejuni)

📌 Causes & Risk Factors
• Triggered by infection:
 – Campylobacter jejuni (most common), CMV, EBV, Mycoplasma, Influenza, HIV, Zika
• Also linked to:
 – Recent surgery or trauma
 – Rarely: vaccines (notably influenza), Hodgkin lymphoma
• More common in males and in post-partum women

📌 Pathophysiology
• Molecular mimicry: immune system targets nerve myelin due to resemblance to infectious agents
• Leads to inflammatory demyelination—nerve signals are slowed/disrupted

📌 Variants
• AIDP (acute inflammatory demyelinating polyradiculoneuropathy) – classic form
• AMAN/AMSAN (motor/sensory axonal forms) – direct axonal damage
• Miller-Fisher syndrome: triad of ophthalmoplegia, ataxia, areflexia—linked with anti-GQ1B antibodies (90%)

📌 Symptoms
• Ascending, symmetrical muscle weakness (starts in legs → arms)
• Areflexia (loss of reflexes)
• Tingling/paraesthesia in hands & feet
• Pain (esp. back/legs, often early)
• Facial weakness, swallowing difficulties
• Respiratory muscle weakness: can cause respiratory failure
• Autonomic dysfunction (arrhythmia, blood pressure swings, sweating)

📌 Differential Diagnosis
• CIDP (chronic form)
• Myasthenia gravis
• Botulism
• Transverse myelitis
• Stroke
• Hypokalaemia
• Other neuropathies/myopathies

📌 Diagnosis
• Clinical diagnosis + nerve conduction studies (slowed conduction in demyelinating type; may be normal early!)
• CSF: high protein, normal white cells = albuminocytologic dissociation (classic)
• Miller-Fisher: check for anti-GQ1B antibodies
• FVC <20ml/kg = ICU threshold
• MRI (to exclude cord compression if diagnosis unclear)

📌 Management
• Admit to hospital for monitoring (risk of respiratory failure/autonomic instability)
• IVIG or plasma exchange (both effective, IVIG often easier to administer)
• DO NOT use corticosteroids (not effective, may delay recovery)
• Early DVT prophylaxis (compression stockings, LMWH)
• Physiotherapy & occupational therapy—start early
• Pain management (gabapentin, pregabalin, opiates if needed)
• Close monitoring of FVC and vital signs

📌 Complications
• Respiratory failure (may need ventilation)
• Autonomic instability (arrhythmias, BP swings)
• DVT/PE, infections (esp. pneumonia, UTI)
• Long-term weakness, chronic pain, contractures
• Psychological distress/anxiety

📌 Prognosis
• 80% walk independently by 6 months
• 3–10% mortality (mainly from respiratory failure/PE/sepsis)
• Poor prognosis if: older age, rapid onset, severe weakness, need for ventilation, Campylobacter trigger

🧠 FREE MSRA PODCAST – Frontotemporal Dementia (FTD): Behaviour, Language & the Younger Brain
Dive 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

⚕️ FREE MSRA PODCAST – Extradural Haematoma (EDH)
🎧 A rapid, high-yield breakdown of this neurosurgical emergency — ideal for exam prep and acute clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Extradural haematoma (EDH), also called epidural haematoma, is a collection of blood between the skull and dura mater
• Most often caused by trauma, typically from a temporal bone fracture
• Usually due to rupture of the middle meningeal artery
💡 Mnemonic: "Lucid, then lose it" – classic for EDH

📌 Causes & Risk Factors
• Head trauma (most common) – e.g. RTA, fall, assault
• Middle meningeal artery rupture (classic), but can be from venous sinuses or contralateral surgery
• Risk Factors:
– Contact sports
– Alcohol misuse
– Skull fracture history
– Anticoagulant use
– Age 20–40, M:F ratio 4:1

📌 Pathophysiology
• Arterial bleed rapidly increases intracranial pressure (ICP)
• Blood collects in tight extradural space → compression of brain → herniation risk
• Classic CT: biconvex/lens-shaped (lemon-shaped) haematoma

📌 Symptoms
• Initial LOC → lucid interval → rapid decline
• Severe headache, vomiting, confusion, seizures
• Focal neurology (e.g. pupil dilation, hemiparesis)
• Seizures, unequal pupils, brisk reflexes
⚠️ Don’t rely on lucid interval – not always present

📌 Differential Diagnosis
• Subdural haematoma (crescent shape, venous, slower)
• Intracerebral haemorrhage
• Brain tumour
• Abscess
• Post-concussion syndrome
• Alcohol or drug intoxication
• Stroke or TIA

📌 Investigations
• Urgent non-contrast CT head – gold standard
• Look for biconvex haematoma, skull fracture, mass effect
• Avoid lumbar puncture – risk of herniation
• Bloods: FBC, U&E
• Cervical spine CT if trauma
• Repeat CT if deterioration

📌 Management
• ABC resuscitation first
• Urgent neurosurgical referral
• Definitive: craniotomy or burr holes to evacuate clot
• ICP control:
– IV mannitol or hypertonic saline
– Elevate head of bed
– Controlled hyperventilation (short term)
• DVT prophylaxis (low-dose heparin), PPI for GI protection
• Conservative management only in small, stable EDH with close monitoring

📌 Prognosis
• Excellent if diagnosed and treated early
• Poorer if: GCS < 8, dilated pupil, decerebrate posturing
• Mortality ≈ 30%, but much better if alert on admission
• Worse in age >75
• Risks of seizures, cognitive impairment, long-term deficits if delayed treatment

📌 Complications
• Brain herniation
• Long-term neuro deficits
• Post-traumatic seizures (esp. in alcoholics)
• Post-concussion syndrome
• Spinal EDH: weakness, incontinence, neuropathic pain

⚕️ FREE MSRA PODCAST – Epilepsy
🎧 A high-yield, exam-focused breakdown of this chronic neurological disorder with recurrent seizures – essential for clinical and exam mastery.

🧠 Key Learning Points

📌 Definition
• Epilepsy = chronic neurological disorder with recurrent, unprovoked seizures
• Caused by abnormal, hypersynchronised electrical activity in the brain
• Diagnosis = ≥2 unprovoked seizures, separated by >24h

📌 Causes & Risk Factors
• Idiopathic (unknown) in most
• Secondary: brain injury/trauma, stroke, CNS infections, tumours, genetic syndromes, neurodevelopmental conditions, prenatal injury, metabolic derangements
• Triggers: alcohol, certain drugs, sleep deprivation, flashing lights
• Risk ↑ in childhood & >60y, and with learning disabilities

📌 Pathophysiology
• Abnormal electrical discharges disrupt normal brain function
• Neurotransmitter imbalance (too much excitation, not enough inhibition)
• Ion channel dysfunction, structural brain lesions

📌 Symptoms
• Wide range: convulsions, loss of awareness, sensory/motor/autonomic changes, auras, postictal confusion
• Generalised: tonic-clonic, absence, myoclonic
• Focal: motor (jerking, Jacksonian march), sensory (deja vu, jamais vu), emotional
• Postictal state: confusion, headache, fatigue

📌 Classification (ILAE)
• Focal (one area): aware, impaired awareness
• Generalised (both hemispheres): tonic-clonic, absence, myoclonic, atonic
• Unknown onset
• Focal to bilateral (secondary generalised)

📌 Differential Diagnosis
• Syncope (faint), psychogenic non-epileptic seizures (PNES), sleep disorders, TIAs, migraines with aura, metabolic disturbances, movement disorders

📌 Diagnosis
• Clinical history (eyewitness account vital)
• EEG: abnormal patterns, helps classify
• Brain MRI (preferred) or CT: rule out lesions, tumours
• Bloods: metabolic, genetic, infection screens
• Consider ECG (exclude cardiac cause), neuropsychology, genetic testing

📌 Management
Acute:
• Status epilepticus = emergency (ABCDE, benzodiazepines, escalation)
Long-term:
• Anti-epileptic drugs (AEDs):
 – Generalised: sodium valproate 1st line (⚠️ avoid in pregnancy)
 – Absence: sodium valproate or ethosuximide
 – Myoclonic: sodium valproate
 – Focal: carbamazepine or lamotrigine
• Alternatives: levetiracetam, clonazepam, oxcarbazepine
• Non-drug: ketogenic diet (esp. in children), vagus nerve stimulation, epilepsy surgery (for localised, drug-resistant cases)
• Lifestyle: sleep hygiene, trigger avoidance, driving safety (DVLA rules!), psychosocial support

📌 Complications
• Status epilepticus, injuries (falls, drowning, burns), cognitive impairment, psychiatric (anxiety, depression, stigma), medication side effects, bone health issues (osteoporosis), SUDEP (sudden unexpected death in epilepsy)

📌 Prognosis
• 70% achieve remission (5y seizure-free, often off meds)
• Worse outlook if multiple seizure types, learning disabilities, abnormal neuro exam, structural brain abnormality
• 25% of all cases occur in those with learning disabilities
• Misdiagnosis rates up to 30% in adults!

⚕️ FREE MSRA PODCAST – Migraine
🎧 A clear, high-yield breakdown of this complex neurological disorder with recurrent headaches – ideal for exam prep and clinical practice.

🧠 Key Learning Points

📌 Definition
• Migraine = recurrent, moderate-severe headaches, often with nausea, photophobia (light), phonophobia (sound)
• May occur with or without aura (reversible neurological symptoms)
💡 Mnemonic for diagnosis: P-U-M-A
 • Pulsating
 • Unilateral
 • Moderate/severe
 • Aggravated by activity

📌 Causes & Risk Factors
• Genetic predisposition plus environmental/lifestyle triggers
• Triggers: stress, hormones (menstruation, pregnancy, menopause), poor sleep, alcohol, certain foods, sensory stimuli, weather
• Risk factors: family history, female sex (2–3× more common), depression/anxiety, epilepsy, lack of sleep, excess caffeine/alcohol

📌 Pathophysiology
• Activation of trigeminovascular system → neurogenic inflammation
• Cerebral vasodilation, neurotransmitter imbalance
• Dynamic, not just a headache!

📌 Symptoms
• Unilateral, throbbing/pulsating pain, 4–72h, worsened by routine activity
• Associated: nausea/vomiting, photophobia, phonophobia
• ± Aura: visual (scintillating scotoma, hemianopia), sensory, or speech symptoms
• Stages: prodrome, aura, headache, postdrome (“migraine hangover”)

📌 Differential Diagnosis
• Cluster headache, tension-type headache, medication-overuse headache
• Brain tumour, subarachnoid haemorrhage, temporal arteritis, IIH, stroke, sinusitis

📌 Diagnosis
• Clinical (ICHD-3 criteria): ≥5 attacks, 4–72h, ≥2/4 PUMA features, ≥1 of N/V or photo/phonophobia
• Red flags (investigate!): new onset after 50, atypical aura, “worst ever” headache, focal neuro deficit, papilloedema, seizures, thunderclap onset
• Tests if red flags: ESR (GCA), LP (SAH/meningitis), CT/MRI (tumour), fundoscopy

📌 Management
Acute:
• Oral triptan + NSAID/paracetamol
• Nasal triptan (age 12–17)
• Anti-emetics (metoclopramide/prochlorperazine)
Prophylaxis:
• Topiramate or propranolol (tailored to patient)
• Acupuncture, riboflavin (vitamin B2)
• Menstrual: mini-prophylaxis (frovatriptan/zolmitriptan)
• Lifestyle: sleep hygiene, trigger avoidance, mindfulness/CBT
Special:
• Combined pill contraindicated with aura (↑stroke risk): use progestogen-only
• Pregnancy: paracetamol preferred, avoid triptans if possible, consider propranolol/amitriptyline if needed

📌 Complications
• Chronic daily headache, status migrainosus (>72h), migrainous infarction (rare stroke)
• Medication overuse headache
• Psychiatric: depression, bipolar, anxiety
• ↑ Risk of stroke (esp. with aura), significant impact on work/social life

📌 Prognosis
• Chronic, but often improves with age/menopause; pregnancy can lessen attacks
• Attacks/disability vary by person and triggers

⚕️ FREE MSRA PODCAST – Stroke
🎧 A clear, high-yield breakdown of this life-changing neurological emergency – perfect for exam prep and clinical practice.

🧠 Key Learning Points

📌 Definition
• Stroke = sudden disruption of brain blood supply, leading to brain cell death
• Classified as ischaemic (blockage, ~80%) or haemorrhagic (bleed, ~15%)
• TIA (“mini-stroke”): symptoms resolve within 24 hours, but signal major risk

📌 Causes & Risk Factors
• Ischaemic: atherosclerosis, AFib, carotid stenosis, emboli, diabetes, hypertension
• Haemorrhagic: uncontrolled hypertension, aneurysm, AVM, anticoagulation, trauma
• Others: vasculitis, thrombophilia (young), previous TIA/stroke
💡 Mnemonic: “Stroke HAPPENS FAST” – Hypertension, AFib, Plaques, Previous TIA, Emboli, Non-modifiable, Smoking / Sedentary, Family history, Age, Sex, Thrombophilia

📌 Pathophysiology
• Blockage (ischaemic): vessel occlusion → ischaemia → infarction
• Bleed (haemorrhagic): vessel rupture → mass effect, raised ICP, direct toxicity
• “Time is brain”: irreversible damage within minutes!

📌 Symptoms
• Sudden weakness/numbness (esp. face/arm/leg, usually one side)
• Speech disturbance (dysphasia, slurred)
• Visual loss (hemianopia), confusion, balance issues, severe headache (think bleed)
• FAST: Face, Arms, Speech, Time to call 999
💡 Mnemonic: “FAST” – Face, Arm, Speech, Time

📌 Differential Diagnosis
• TIA, migraine with aura, seizure/post-ictal state
• Brain tumour, abscess, encephalitis, subdural haematoma
• Metabolic: hypoglycaemia, electrolyte imbalance, intoxication

📌 Diagnosis
• Emergency CT/MRI brain: confirm type (bleed vs. clot)
• ECG (AFib), bloods (glucose, FBC, U&Es, clotting, lipids), carotid Doppler
• Use ROSIER score in ED; swallow screen before oral intake
💡 Tip: Imaging always before antiplatelet!

📌 Management
• Admit to specialist acute stroke unit ASAP
• Ischaemic: IV thrombolysis within 4.5 hrs (if eligible), thrombectomy (within 6 hrs), aspirin after bleed excluded
• Haemorrhagic: manage BP, neurosurgery if needed
• Support: swallow screen (NBM if unsafe), early mobilisation, DVT prophylaxis, rehabilitation
• Secondary prevention: clopidogrel, statin, manage risk factors

📌 Complications
• Long-term disability: weakness, aphasia, vision loss, dysphagia, incontinence
• Cognitive/psychological: depression, emotionalism, dementia
• Medical: DVT/PE, pneumonia, pressure sores
• Recurrence: high risk of further strokes

📌 Prognosis
• 85% survive to discharge, but ~2/3 with disability; 1 in 4 risk of recurrence in 5 years
• Prompt treatment = better outcomes; delays = permanent loss
