Neuro Flashcards
Migraine management acute and prophylactic
Acute: paracetamol/aspirin + triptan (sumatriptan) + NSAID
Prophylactic: propranolol/topiramate/amitriptyline
Trigeminal neuralgia management
Carbamazepine, gabapentin 2nd line
Unresponsive to medical therapy:
Classical - micro vascular decompression
Idiopathic - ablative surgery
Secondary - treat secondary cause
Focal seizure management
Lamotrigene/levetiracetam
Generalised seizure management
Sodium valproate/valproic acid
Status epilepticus management
Benzodiazepine - lorazepam/diazepam
Second line - IV phenytoin
How does a focal seizure present (different areas of brain)
Frontal: Jacksonian March (muscle spasm), post-ictal flaccid weakness, disinhibition
Temporal: Automatisms, epigastric discomfort, hallucinations
Parietal: Sensory disturbances e.g. tingling, pain, numbness
Occipital: visual phenomena
What investigation is done for a brain abscess and what do you expect to see
CT head/MRI for ring enhancing lesion
Brain abscess management
Vancomycin + metronidazole/clindamycin + ceftriaxone (3rd gen ceph)
Anticonvulsants: phenytoin/carbamazepine/valproic acid/levetiracetam
Dexemethasone in acutely decompensating patient
Surgical decompression
Management for essential tremor
Propranolol
Primidone (barbiturate) sometimes
Management for Bell’s palsy
Oral prednisolone
Eye protection e.g. artificial tears
Severe palsy/complete paralysis:
Consider antiviral therapy (valaciclovir)
No improvement after 3 weeks —> refer to ENT urgently
Management for encephalitis?
IV acyclovir initially if viral cause suspected (most common)
Investigations for encephalitis and results
Diagnostic MRI shows hyper intense lesions
CT brain in all patients with altered mental status
CSF analysis if 2/4 symptoms present: fever, headache, altered mental status, meningismus
EEG
Management for meningitis
GP: benzylpenicillin IM/IV + hospital admission
Hospital: IV ceftriaxone/cefotaxime + IV dexamethasone within 1 hour
If viral cause confirmed: supportive care e.g. paracetamol/ibuprofen
Investigations for meningitis
Lumber puncture for CSF analysis
CT head before LP if any symptoms of raised ICP or reduced consciousness
2 blood cultures before ABs (don’t delay however)
Blood glucose
FBC
Management for meniere’s
Nausea/vomiting: prochlorperazine
Vertigo: vestibular suppressant (meclizine)/anti-emetic/corticosteroid
Tinnitus: tinnitus maskers
Sudden hearing loss: corticosteroid
Prophylaxis: betahistine trial
If therapies fail do surgery
