Headache Flashcards
(38 cards)
Acute single headache
Febrile illness, sinusitis First attack of migraine Following a head injury Subarachnoid haemorrhage Meningitis, tumour, drugs, toxins, stroke Thunderclap (sudden onset), low pressure
Dull headache, increasing in severity
Usually benign Overuse of medication (e.g. codeine) Contraceptive pill, hormone replacement therapy Neck disease Temporal arteritis Benign intracranial hypertension Cerebral tumour Cerebral venous sinus thrombosis
Triggered headache
Coughing, straining, exertion
Coitus
Food and drink
Recurrent headaches
Migraine
Cluster headache
Episodic tension headache
Trigeminal or post-herpetic neuralgia
Dull headache, unchanged over months
Chronic tension headache
Depressive, atypical facial pain
Red Flags
Thunderclap, acute, subacute - onset
Photophobia, phonophobia, stiff neck, vomiting - meningism
Fever, rash, weight loss - systemic
Visual loss, confusion, seizures, hemiparesis, double vision, 3rd nerve palsy, Horner syndrome, papilloedema - neurological
Better lying down
Strictly unilateral
Focal Signs
Double vision
3rd nerve (oculomotor) palsy
Horner syndrome
Subarachnoid Haemorrhage
Sudden generalised headache, ‘blow to the head’.
Meningism - stiff neck and photophobia
Around 50% are instantly fatal.
High risk of a further bleed.
CT brain, Lumbar puncture (RBC and xanthochromia) and MRA, angiogram.
Aneurysm treatment
Aneurysms used to be clipped or wrapped.
Nowadays filled with platinum coils.
Acute intracerebral bleed
Fatal haemorrhage due to coning.
Raised Intracranial Pressure (ICP)
Mechanism of coning.
Papilloedema
Optic disc swelling due to raised ICP
Carotid and Vertebral Arteries
Headache can also arise due to pathology in the large arteries of the neck.
Headache and neck pain common
Mean age 40, carotid > vertebral
Carotid and Vertebral artery treatment
Aspirin or anticoagulation X 6/12
Temporal Arteritis
Over the age of 55.
Three times commoner in females.
Constant unilateral headache, scalp tenderness and jaw claudication
25% Polymyalgia Rheumatica-proximal muscle tenderness.
Elevated ESR and CRP.
Visible on ultrasound.
Biopsy shows inflammation and Giant Cells.
High dose steroids and aspirin.
Disruption of the internal elastic lamina
Cerebral Venous Thrombosis
Thrombosis in dural venous sinus or cerebral vein
Unusual amount of headache due to raised ICP
Non-territorial ischaemia “venous infarcts”
Haemorrhage
Thrombophilia, pregnancy, dehydration, Behcets
Causes of meningitis
Viral- Coxsackie, ECHO, Mumps, EBV
Bacterial - Meningococci, Pneumococci, Haemophilus, Tuberculous
Fungal - Cryptococci
Granulomatous- Sarcoid, Lyme, Brucella, Behçet’s, Syphilis
Carcinomatous
Meningitis
Malaise Headache Fever Neck stiffness Photophobia Confusion Alteration of consciousness
Herpes Simplex Encephalitis
Classic haemorrhagic changes in the temporal lobes
Meningitis treatment
Treat then diagnose
Antibiotics Blood and urine culture Lumbar puncture Increased White Cell Count, decreased glucose Antigens Cytology Bacterial Culture CT or MRI Scan
Sinusitis
Malaise, headache, fever. Blocked nasal passages. Loss of vocal resonance. Anosmia. Nasal or postnasal catarrh. Local pain and tenderness.
Frontal pain characteristically starts 1-2 hours after rising and clears up during the afternoon.
Idiopathic Intracranial Hypertension
Pseudotumor Cerebri
Often young obese women
Headache, visual obscurations, diplopia, tinnitus
Papilloedema, +/- visual field loss
Drugs: hormones, steroids, antibiotics, vitamin E
Treatment: weight loss, diuretics, optic nerve sheath decompression, lumboperitoneal shunt, stenting of stenosed venous sinuses.
Low pressure headache
CSF leak due to tear in dura
Traumatic post lumbar puncture or spontaneous
Treatment rehydration, caffeine, blood patch
Chiari Malformation
Normal brain that just sits very low within the skull
Cerebellar tonsils descending through the foramen magnum. Descend further when patient cough and tug on the meninges causing cough headache.
