Q

What is the underlying pathophysiology of a migraine headache?

A

Cortical spreading of depolarisation In the dorsal raphe nucleus and locus coeruleus, causing activation of trigeminal vascular system and vasodilation of blood vessels which then causes pain.

Q

What investigations are used for IIH and what do they show?

A

Fundoscopy: bilateral papilloedema, enlarged blind spot

CT/MRI: “slit like ventricles”

Lumbar puncture: raised opening pressure

21
Q

Treatment for idiopathic intracranial hypertension?

A

Ace
WEIGHT LOSS
Tazolamide
shunt CSF from ventricles to peritoneum

22
Q

What is trigeminal neuralgia?

A

Chronic neuropathic pain in distribution of CN V (cranial nerve 5)

23
Q

Causes of trigeminal neuralgia?

A

Compression from superior cerebellar artery
AVM (arteriovenous malformation - tangle of blood vessels that irregularly connects arteries and veins, disrupting blood flow and oxygen).
Tumours
MS (multiple sclerosis)
Injury to the nerve (eg stroke or trauma)

24
Q

What does the patient present with in trigeminal neuralgia?

A

Severe pain when chewing and talking, pain on contact (eg shaving, washing face) with psychological consequences

25
Q

What imaging is used for trigeminal neuralgia?

A

MRI to rule out MS or tumour

26
Q

Treatment of trigeminal neuralgia?

A

Pain relief (carbamazapine or amitriptyline)

27
Q

Possible surgical treatment of trigeminal neuralgia?

A

Microvascular decompression (a surgery to relieve abnormal compression of a cranial nerve)

Balloon compression

Radiofrequency ablation

28
Q

Worst headache ever, feels like a hit to the back of the head. What is it?

A

Subarachnoid haemorrhage

29
Q

Headache + paralysis, weakness on 1 side of body and face, slurred speech. What is it?

A

Stroke

30
Q

Headache + fever, stiff neck, mental confusion, seizures, double vision. What is it?

A

Meningism (shares same symptoms as meningitis but without meningeal inflammation).

CSF pressure may be elevated but CSF is normal.

31
Q

Headache “behind the eye” and other neuro complications. What is it and what condition is it associated with?

A

Optic neuritis - inflammation of the optic nerve. Strong association with MS.

32
Q

New headache which wakes you +/- vomiting. What is it?

A

Brain tumour - RED FLAG

33
Q

What type of drug are triptans?

A

Serotonin receptor agonists

34
Q

Mechanism of triptans?

A

In acute attacks, triptan binds to the specific serotonin receptors causing intracranial vasoconstriction leading to decreased blood flow causing the attack to calm.

35
Q

Triptans are usually used first line in combination with NSAID or paracetamol. true/false?

A

True

36
Q

Contraindications of triptans?

A

Patient with history or significant risk factors of, ischaemic heart disease or cerebrovascular disease.

37
Q

For migraine with aura, some patients report beginning of onset 48 hours before headache. True/false?

A

True

38
Q

In migraine with aura, what phase occurs before the headache?

A

Prodromal phase

39
Q

Features of prodromal phase of migraine with aura?

A

Severe visual symptoms occurring 60 mins before headache appearance
Irritability
Depression
Frequent yawning
Hyperexcitability

40
Q

What can migraine with aura be referred to as?

A

Classic migraine

41
Q

For migraine with aura, what visual symptoms can occur before headache (around 60 mins before)?

A

Flashes of light (photopsia)
Wavy linear patterns on visual field (fortification spectra)
Migrating scotoma
Blurred vision

42
Q

Characteristic of migraine with aura?

A

Headache itself usually described as pulsatile or throbbing

43
Q

Typically duration of migraine with aura headache?

A

4-72 hours

44
Q

Migraine with aura will show abnormal MRI. True/false?

A

False

MRI will be normal

45
Q

Common symptoms occurring alongside headache with classic migraine?

A

Nausea
Vomiting
Photophobia (light sensitivity)
Phonophobia (sound sensitivity)
Irritability
Malaise

46
Q

What is first-line prophylaxis (prevention) for migraine?

A

Propranolol

47
Q

If propranolol is contraindicated, what is second line prophylaxis for migraine?

A

Topiramate

48
Q

What are some signs that could be present in meningitis?

A

Kernig’s sign

Nuchal rigidity

Brudzinski’s sign

49
Q

What is Kernig’s sign?

A

Positive when the thigh is flexed at the hip and knee at 90 degree angles, and subsequent extension in the knee is painful (leading to resistance).

This may indicate subarachnoid hemorrhage or meningitis.

50
Q

What is nuchal rigidity?

A

The inability to flex the neck forward due to rigidity of the neck muscles; if flexion of the neck is painful but full range of motion is present, nuchal rigidity is absent.

51
Q

What is a positive Brudzinski’s sign?

A

Is positive when the forced flexion of the neck elicits a reflex flexion of the hips, with the patient lying supine.

Basically when lying down and neck flexed forward, hips flex and knees come up
