Q

Why is decreased level of consciousness concerning with a headache?

A

1; SAH need exclusion

  1. if history of head injury could suggest subdural haematoma (fluctuating consciousness) or extradural haematoma (altered conciousness following a lucid interval)
  2. meningitis and encephalitis can affect consciousness

Q

Why are seizure(s) or focal neurological deficet (e.g. limb weakness, speech difficulties) with a headache worrying?

A

Q

What could be a sinister past medical history with a headache?

A
  1. history of malignancy that is known to metastasize to the brain (e.g. lung, breast)

Q

What basic obs do you carry out to exclude sinister reasons for a headache?

A
  1. Altered consciousness: GCS
  2. Blood Pressure + pulse: check for malignant hypertension
  3. Temperature: fever and headache suggest intracranial infection

25
What is 3rd nerve palsy?
1. ptsosis 2. mydriasis 3. eye deviated down and out
26
What is a cause of 3rd nerve palsy?
1. SAH due to ruptured aneurysm of the posterior communicating artery 2. PCOM arterys are a cause of headache
27
What is 6th nerve palsy?
convergent squint and/or failure to abduct eye laterally
28
Why does 6th nerve palsy happen?
compressed either directly by a mass or indirectly by raised ICP
29
How do you look for 12th nerve palsy?
look for tongue deviation
30
When can 12th nerve palsy happen with a headache?
arise from a carotid artery dissection
31
What is Horner's syndrome?
1. partial ptsois 2. miosis 3. anhyrdosis
32
Why does Horner's syndrome happen?
results from interruption of ipsilateral sympathetic pathway
33
What would Horner's syndrome with a headache indicate?
- carotid artery dissection | - cavernous sinus lesion
34
What would exophalmos with a headache suggest?
retro-orbital process such as cavernous sinus thrombosis
35
What would a cloudy cornea fixed, dilated/oval pupil suggest with a headache?
acute glaucoma
36
What would you look for in the fundoscopy with a headache?
papilloedema
37
What would papilloedema suggest?
raised ICP
38
What would reduced visual acuity with a headache suggest?
- acute glaucoma | - temporal arteritis
39
What would scalp tenderness with a headache suggest?
temporal arteritis
40
What do you check for in meningism with a headache?
- patient has a stiff neck - photophobia - suggesting meningism due to infection or SAH
41
What sort of emergency is temporal arteritis?
opthalamological
42
How do you treat and diagnose temporal arteritis?
1. Blood test for ESR and CRP to see if elevated which would be consistent with a systemic inflammation such as temporal arteritis 2. To reduce immune mediated inflammation: high dose corticosteroids 3. Then temporal artery biopsy

2. Unilateral stabbing, sharp facial pain involving one or more of divisions of trigeminal nerve
56

What is the common demographic for trigeminal neuralgia?
60/70 (rare)

59
When is medication overuse headaches common?
w/Migraine medications and analgesics

What is the pain like in medication overuse headaches?
either migraine or tension type headache
61
What is the pain like in sinusitis?
1. Facial pain coming on over hours to days with coryzal symptoms 2. Pain is tight and exacerbated by movement
62
How long does sinusitis last?
last several days with time course consistent with the infection
63
What type of headache gives pulsatile, throbbing pain that is usually unilateral?
migraines
64
How long to migraines last?
7. Last between 4-72 hours unless successfully treated
65
What type of headache gives bifrontal pain described as pressure or tightness around the head like tightening band?
tension headache
66
Are there any other features apart from a headache in tension headaches?
No
67
How long do tension headaches last and how often do they happen?
1. Episodic occurring in variable frequency 2. Only last a few hours and no severely disabling 3. Rare cases occur daily
68
What are triggers for tension headaches?
stress and fatigue
69
What does migraine treatment involve?
Triptans Analgesics Antiemetics
70
How do you ensure it is a sinister cause and why?
CHECK: 1. BP: to exclude malignant hypertension 2. Head and neck examination: for muscle tenderness, stiffness or limited movement which can occasional mimic tension type headaches 3. Focal neurological signs: should alter intracranial pathology 4. Fundoscopy: to exclude raised intracranial pressure
