- stroke
- thunderclap
- low pressure
What are the possible causes of a dull headache, increasing in severity?
- benign
- overuse of medication
- contraceptive pill
- HRT
- neck disease
- temporal arteritis
- benign intracranial hypertension
- cerebral tumour
- cerebral venous sinus thrombosis
What tends to cause a dull headache, unchanged for months?
- chronic tension headache
- depressive, atypical facial pain
What are different forms of recurrent headaches?
- migraine
- cluster headache
- episodic tension headache
- trigeminal/post-herpetic neuralgia
What are the red flags for a headache?
- onset
- meningism
- systemic symptoms
- neurological symptoms or focal signs
- orthostatic
- strictly unilateral
What types of onset are red flags?
- thunderclap
- acute
- subacute
What forms of meningism are red flags?
- photophobia
- phonophobia
- stiff neck
- vomiting
Which systemic symptoms are red flags?
- fever
- rash
- weight loss
Which neurological symptoms are red flags?
- visual loss
- confusion
- seizures
- hemiparesis
- papilloedema
What does orthostatic mean?
the headache is better when lying down
Which focal signs are red flags?
- double vision
- 3rd nerve palsy
- Horner syndrome
How are subarachnoid haemorrhages caused?
- ruptured aneurysm
- arteriovenous malformations
How do subarachnoid haemorrhages present?
- sudden, generalised head ache (‘blow to the head’)
- meningism (photophobia, stiff neck)
How do you diagnose a subarachnoid haemorrhage?
- 50% are instantly fatal
- early neurological assessment
- brain CT
- lumbar puncture (RBC and xanthochromia)
- MRA
- Angiogram
How do you treat a subarachnoid haemorrhage?
- vasospasm may stop the leak
- nimodipine
- blood pressure control
- high future risk of a bleed
- coiling an aneurysm
How do you manage aneurysm?
- clip or wrap
- filled with a platinum coil to prevent rupture
How are most haemorrhages fatal?
due to coning
What is coning?
- movement of the cerebellar tonsils down through the foramen magnum.
- It leads to compression of the lower brainstem - leading to cardiovascular and respiratory instability
What is papilloedema?
optic disc swelling
- due to raised inter-cranial pressure
What can cause a trigger headache?
- coughing, straining, exertion
- coitus
- food and drink
What are the symptoms of a carotid and vertebral artery dissection?
- headache
- neck pain
When are carotid and vertebral arterial dissections most common?
mean: 40yo
carotid is more common than vertebral
(cause of 20% of ischaemic strokes in those <45yo)
How do you diagnose a carotid/vertebral dissection?
- MRI/MRA
- Doppler
- Angiography
How do you treat a carotid/vertebral dissection?
aspirin or anticoagulation
