Name the 6 red flags for headache
- onset
- meningism
- systemic symptoms
- neurological symptoms or focal signs
- orthostatic - better lying down
- strictly unilateral
what would be the worry of an acute onset headache?
thunderclap/ acute - could be a symptom of something serious
give 4 symptoms of meningism
photophobia, phonophobia (sound), stiff neck, vomiting
visual loss, confusion, seizures, hemiparesis, double vision, 3rd nerve palsy, Horner syndrome and papillodema are all what kind of red flag?
neurological symptoms or focal signs
what causes double vision?
Any of the 3rd, 4th and 6th cranial nerves not working
what causes 3rd nerve (oculomotor) palsy?
posterior communicating artery aneurysm
what are the signs of 3rd nerve (oculomotor) palsy?
A complete third nerve palsy causes a completely closed eyelid and deviation of the eye outward and downward. The eye cannot move inward or up, and the pupil is typically enlarged and does not react normally to light.
What happens in Horner Syndrome? What causes it?
pupil size bigger, eye held open
sympathetic supply to eye is altered
what other symptoms can a subarachnoid haemorrhage cause?
meningism - stiff neck and photophobia
What are subarachnoid haemorrhages caused by?
ruptured aneurysm
What percentage of subarachnoid haemorrhages are fatal?
50%
how do you confirm a subarachnoid haemorrhage?
CT of the brain, lumbar puncture (spinal fluid contains blood), MRA, angiogram
how do you treat an aneurysm?
fill with platinum coil –> causes blood vessel to seal up
is an acute intracerebral bleed fatal?
yes, due to coning
what is coning?
the brain can only handle an increased volume/ pressure up to a certain point. After this, there is herniation due to the brain squeezing out of the skull at certain points. This squashes the brainstem, shutting down cardiorespiratory centres and is fatal.
papilloedema is what?
optic disc swelling at the back of the eye due to raised intracranial pressure
headache in the front of the head and temples could be affected by a problem with which arteries?
carotid
headache from the middle of the head towards the back of the head and neck could be caused by a problem with which artery?
vertebral
