Headache Flashcards
List patterns of headache.
acute single headache dull headache, increasing in severity dull headache, unchanged over months recurrent headache triggered headache
Possible explanations for dull headache increasing in severity?
usually benign, medication overuse, HRT/contraceptive pill, neck disease, temporal arteritis, benign intracranial hypertension, cerebral tumour, cerebral venous sinus thrombosis
Possible explanations for acute single headache?
febrile illness, sinusitis, 1st attack of migraine, after head injury, subarachnoid haemorrhage, meningitis, tumour, drugs, toxins, stroke, thunderclap
Possible explanations for dull headache unchanged over months?
chronic tension headache
depressive, atypical facial pain
Possible explanations for recurrent headaches?
migraine
cluster headache
episodic tension headache
trigeminal or post herpetic neuralgia
Possible explanations for triggered headaches?
coughing, straining, exertion
coitus
food and drink
What are red flags for headaches?
onset: thunderclap, acute, subacute
meningism: photophobia, phonophobia , stiff neck, vomiting
systemic symptoms, neurological symptoms, orthostatic, strictly unilateral
List examples of focal signs.
double vision Horner syndrome 3rd nerve (oculomotor) palsy
list vascular and circulatory causes of headache

list infective causes of headache
herpes simplex encephalitis
meningitis
sinusitis
list causes of headaches involving intracranial pressure
brain tumour
idiopathic
chiari malformation
obstructive sleep apnoea
list facial pain causes of headache
trigeminal neuralgia
atypical facial pain
list traumatic causes of headache
post traumatic headache
management of post traumatic headache
list cervicogenic pain causes of headache
cervical spondylosis
symptoms of subarachnoid haemorrhage
sudden generalised headache, meningism - stiff neck and photophobia
most subarachnoid haemorrhages are caused by?
ruptured aneurysm
some subarachnoid haemorrhages are caused by?
arteriovenous malformations
unexplained
what % of subarachnoid haemorrhages are instantly fatal?
50
what physiological action may stop the leak in a subarachnoid haemorrhage?
vasospasm (sudden constriction of a blood vessel)
list medication used to treat subarachnoid haemorrhage
diazepam (manage mental conditions)
amlodipine (reduce BP)
clonazepam (seizure prevention)
list surgical procedures used to treat subarachnoid haemorrhage
craniotomy
endovascular coiling
why is nimodipine used in subarachnoid follow up treatment?
prevention of problems after a subarachnoid haemorrhage > high risk of further bleed
imaging used in assessment of subarachnoid haemorrhage
CT brain
lumbar puncture (RBC and xanthochromia) and MRA
angiogram
what is aneurysm coiling?
instead of clipping ro wrapping, fill the aneurysm with platinum coils
cause of acute intracerebral bleed?
coning
coning refers to?
the herniation of the brain through the foramen magnum
mechanism of coning
raised intracranial pressure
what is papilloedema?
optic disc swelling due to raised intracranial pressure
headache can arise due to pathology of what large neck arteries?
vertebral
carotid
mean age for carotid/vertebral artery dissection
40
which is more common: carotid or vertebral artery dissection?
carotid
carotid and vertebral artery dissection can be divided into what causative categories?
traumatic
spontaneous
imaging for carotid + vertebral artery dissection
MRI/MRA
Doppler
angiography
treatment for carotid and vertebral artery dissection
aspirin or anticoagulation
