Q

What action outlines the aura phase?

A

Cortical spreading depression (CSD) resulting in slow-spreading depolarisation within the grey matter that inhibits cortical activity

CSD may also activate the trigeminovascular system, driving aura symptoms

16
Q

What action outlines the ictal phase?

A

neuropeptides (including CGRP) sensitise the trigeminovascular system and create a state of hypersensitivity

17
Q

What action outlines the postdrome phase?

A

Similar to prodrome:
hypothalamus activation and neuropeptide release

18
Q

What action outlines the interictal phase?

A

Some regions of the brain remain abnormally activated after headache cessation, including the olfactory regions, the midbrain, and the hypothalamus

19
Q

How is episodic migraine diagnosed

A

during a lifetime, ≥ 5 migraine attacks lasting 4-72 hours

20
Q

How is chronic migraine diagnosed

A

≥ 15 MHDs and ≥ 8 MMDs over > 3 months

21
Q

What is an MHD

A

monthly HA day

a day with migraine-type or tension-type headache

22
Q

What is an MMD

A

monthly migraine day

at least 2/4: unilateral, pulsating, mod/severe, avoid physical activity

if no aura, at least 1/2: photo/phonophobia, n/v

23
Q

Which two classes of medications are specifically implicated in medication overuse HA?

A

Opioids and barbituates

24
Q

What is the first line and second line for acute migraine treatment?

A

First line: analgesics like NSAIDs or paracetamol/aspirin if NSAIDs are contraindicated

Second line: triptans

25
Q

What are the triptans’ MOA and what do they inhibit? (3)

A

Triptans are agoists of 5-HT(1B) and 5-HT(1D) receptors, decreasing trigeminal neuron activity

they inhibit 3 things:
- cerebral blood vessels,
-vasoactive peptide release by trigeminal neurons
- nociception

26
Q

Which agents can be used for CGRP receptor blockade? (2)

A

erenumab, gepants

27
Q

Which agents can be used for CGRP blockage? (1)

A

monoclonal antibodies like eptinezumab

28
Q

Which agents stimulate 5-HT (1B/1D) receptors

A

triptans

29
Q

Which agents stimulate 5-HT (1F) receptors

A

ditans

30
Q

What can be used for adjunctive treatment?

A

Metoclopramide for nausea

31
Q

What are the contraindications to cafergot use? (4)

A

CVD, CHD, recent stroke, uncontrolled hypertension

(due to vasoactive effect)

32
Q

What does AHS recommend for when to start preventative treatment?

A

in terms of HA days / month, start if
≥ 6 days w no disability
≥ 4 days w some disability
≥ 3 days w severe disability

33
Q

What 2 classes of drugs can be given for preventative treatment of migraines? (2 + 2)

A

ASM (topiramate, valproate)
BB (propranolol, metoprolol)
