Headaches Flashcards
Differentials of Headaches
+Migraine - photophobia, phonophobia, episodic, unilateral, throbbing. Females.
+Subarachnoid haemorrahge - THUNDERCLAP.
+Meningitis - pyrexia, vomiting, neck stiffness.
+Cluster headache - Unilateral pain around eye in clusters of a couple a day and then period of none. Male.
+Tension headache - band-like dull headache
+Giant cell arteritis - tenderness on scalp, jaw claudication. Elderly.
+Raised ICP/SOL - generalised, aggregated on bending, cough, in morning, progressive severity.
+Trigeminal neuralgia - paroxysms of intense stabbing pain, unilateral. Triggered on washing face, shaving, eating.
+Stroke
Migraine symptoms
Unilateral pulsatile or throbbing headache.
Nausea and vomiting.
Photophobia
Phonphobia
Impairs and is worsened by activities of daily living.
Aura before heachache with visual and sensory symptoms (flashing lights, blurred vision, parasethsia, numbness).
Triggers and risk factors of migraines
More common in females. More common in obesity. Risk also increased in COCP, smoking, hypertension, hyperlipidaemia.
Triggers = chocolate, oral contraceptive pill, hangover, alcohol, orgasm, exercise, menses.
Treatment of an acute migraine
Triptan e.g. sumatriptan +NSIAD/pcm. Triptans only licenced for over 18yrs. Do NOT use ergots or opioids. Consider anti-emetic treatment.
Preventative treatment of migraines
Consider if severe, frequent disabling migraines, making patients at risk of OD on analgesic and acute Rx meds (could lead to medication overuse headache).
1st line = Propranolol or topiramate.
2nd line = sodium valproate, gabapentin, pregabalin.
3rd line = Acupuncture.
Giant cell arteritis pathogenesis
Chronic granulomatous inflammation big arteries (vasculitis). Most commonly temporal and occipital.
Epidemiology of giant cell arteritis
More common in females than males. Most common in elderly (if <55yrs consider Takayasu’s arteritis). Commonly seen with polymyalgia rheumitica
Clinical features of giant cell arteritis
Unilateral scalp tenderness (on brushing hair)
Jaw claudication
Visual disturbance - amaurosis fugax, total sudden blindness.
Investigations + treatment for giant cell arteritis
Increases = ESR, CRP, LFT, platelets
Decrease= Hb
Biopsy of temporal artery but do not delay treatment of Prednisolone.
Tension headache info
Throbbing, unilateral, band-like headache. No nausea or neck-stiffness. Treatment with basic analgesia (paracetamol) and stress relief.
Cluster headache epidemiology
More common in males, more common in smokers.
Clinical features of a cluster headache
Unilateral, severe periorbital pain. Blood shot, watery eyes. lacrimation Rhinorrhea Miosis In clusters of multiple headaches over consecutive days then periods of no pain days.
Treatment of acute and preventative meds for cluster headache
Acute = 100% O2 via non-rebreathable mask + Subcut sumatriptan. Preventative = verapamil.
Trigeminal neuralgia causes
Vascular compression of nerve, AVM
Epidemiology of trigeminal neuralgia
more common in females. Mostly mandibular and maxillary branches
