Headaches Flashcards
- tension,
- migraine,
- cluster,
- raised ICP (SOL, hydrocephalus),
- temporal arteritis,
- drugs (nitrates, nifedipine, withdrawal)
all cause what type of headaches?
chronic / recurrent
- trauma,
- cerebrovascular (SAH/ICH/infarction),
- meningitis,
- systemic infection,
- acute angle-closure glaucoma
all cause what types of headaches?
acute headaches
Headaches are divided into primary and secondary.
What is a primary headache and give 4 examples?
Primary = disturbance of pain networks in the absence of damage i.e. no other identifiable cause
- migraine
- tension
- cluster
- analgesia overuse
What is a secondary headache?
2o headaches have an underlying cause identifiable on LP / scans etc
there is activation of nociceptors on pain sensitive structures around the brain…
SAH, meningitis, GCA, idiopathic intracranial HTN, low pressure headaches, malignant HTN, sinusitis
which secondary headache does this describe:
thunderclap, sudden onset, first and worst?
SAH
which secondary headache does this describe:
fever, seizures?
meningitis
which secondary headache does this describe & how do you Rx if?
jaw claudication, >50y/o, visual disturbance
is GCA
–> ESR as emergency –> Rx steroids
What secondary headache does this describe & how Rx it?
young fat females, high pressure headaches + visual loss + papilledema
Idiopathic intracranial HTN
Rx –> lose weight
What secondary headache does this describe & ow Rx?
After LP / epidural
= Low pressure headaches
Conservative management: caffeine, hydration, analgesia
What is the SOCRATES for raised ICP?
S - generalised
O - Gradual
C - ache
R - none
A - N&V, photophobia (meningism signs), vision change, worse leaning forward, seizures, parasthesia
T: progressively worsening
E: worse on walking (gravity, CO2 retention), coughing, bending forward
S: mild to severe
After Ix for headaches e.g. CT head & lumbar puncture
the LP results come back as raised lympocytes, normal glucose and protein. What kind of infection is this?
viral
After Ix for headaches e.g. CT head & lumbar puncture
the LP results come back as raised neutrophils, low glucose and high protein. What kind of infection is this?
bacterial
After Ix for headaches e.g. CT head & lumbar puncture
the LP results come back as xanthochromia. What causes this?
Subarachnoid haemorrhage
A red flag for headaches is unilateral with eye pain what else could this be?
glaucoma/cluster
what are the red flags for headache?
- Sudden onset -SAH
- “Thunderclap” - SAH
- First & worst - SAH
- Unilateral with eye pain - glaucoma/cluster
- Neurological deficit
- Meningism (photophobia, neck-stiffness)
- Decreased consciousness
- Not usual pattern of headaches
- Scalp tenderness in >50s -GCA
- Worse on coughing/in the morning/bending forward -raised ICP
What is the socrates for tension headache?
S - bilateral
O - chronic, usually at end of the day
C - tight band, non-pulsatile
R -
A - scalp muscle tednerness
T - chronic
E - stress
S - mild-to-moderate (able to continue with ADLs)
What is the SOCRATES for a cluster headache?
S - unilateral, around one eye
O - quick develops, 1-2x/day, 15m-2hr
C - sharp stabbing pain
R -
A - facial/eyelid swelling/redness, Horner’s syndrome, runny nose, watery eyes, conjunctival injection/ redness, restlessness/agitation
T - clusters lasting several wks, clusters ~1yrly
E - ?alcohol may trigger, hyperbaric chamber relieves
S - severe (pt restless & agitated)
What is the SOCRATES for migraine?
S- Unilateral
O - Sudden or ~1hr onset, lasts 4-72hrs
C - Throbbing pain
R - Back of head & down neck (rule out meningism - infection, SAH)
A - N&V, photophobia, phonophobia, aura
T - Some constant, some wax & wane
E- physical activity, improved with rest
S - severe
Stabbing shooting pain down the face/jaw line
Triggered by chewing, talking
– What does this describe?
Trigeminal neuralgia
How do you Ix & Rx this?
Young woman, sudden headache, visual loss or change
?venous sinus thrombosis
- bloods
- MRI venogram to diagnose
= thromboembolism management
How do you Ix and Rx this?
S- Unilateral
O - Sudden or ~1hr onset, lasts 4-72hrs
C - Throbbing pain
R - Back of head & down neck (rule out meningism - infection, SAH)
A - N&V, photophobia, phonophobia, aura
T - Some constant, some wax & wane
E- physical activity, improved with rest
S - severe
- Ix of migraine is nothing
- can do CT if uncertain
Rx:
- Abortive: NSAIDS or sumatriptan (SSRI for migraine & cluster headache)
- prophylaxis: beta blockers, Calcium Channel Blockers etc. Topiramate (ca &Na blocker + inc gaba) , carbamazepine (na blocker)
- can use STEROID/BOTOX injections
What is the Ix and management of this headache:
S - unilateral, around one eye
O - quick develops, 1-2x/day, 15m-2hr
C - sharp stabbing pain
R -
A - facial/eyelid swelling/redness, Horner’s syndrome, runny nose, watery eyes, conjunctival injection/ redness, restlessness/agitation
T - clusters lasting several wks, clusters ~1yrly
E - ?alcohol may trigger, hyperbaric chamber relieves
S - severe (pt restless & agitated)
- cluster headaches Ix:
- CT done to rule out SOL
DDx = acute glaucoma
Rx:
- Acute: 100% oxygen & Sumatriptan (SSRI for migraine and cluster headaches)
- Prophylaxis: Verapamil (CaChannelBlocker)
What are the Ix and management of this headache?
S - bilateral
O - chronic, usually at end of the day
C - tight band, non-pulsatile
R -
A - scalp muscle tednerness
T - chronic
E - stress
S - mild-to-moderate (able to continue with ADLs)
Ix & Rx for tension headache:
Ix: none needed
Rx:
- Stress relief & rest
- Paracetamol / NSAIDs
- Prevention: Amitriptyline 10mg (a TCA)
What is the Ix and Rx of this?
Stabbing shooting pain down the face/jaw line
Triggered by chewing, talking
Trigeminal neuralgia:
Ix: MRI necessary to exclude secondary cause
Rx:
- Medical: Carbamazepine (na blocker)
- 2ndLine: Topimarate (ca and na + gaba blocker)/ Gabapentin (inhibs Ca2+)
Or Surgical: Ablative surgery
