Describe the basic pathophysiology of a migraine [3]
- Interaction between primary afferent nociceptive neurons/trigeminovascular system/brainstem/thalamus/hypothalamus/cortex - i.e. brain disorder

- NOT a primary vascular problem
What is the ICHD-3 diagnostic criteria for a migraine? [8]

- aggravation by or causing avoidance of routine physical activity (e.g. walking or climbing stairs)
- During headache at least one of the following:
- nausea and/or vomiting
- photophobia and phonophobia
What are the 4 phases of a migraine? [4]
- Prodrome
- Aura
- Headache
- Postdrome
Prodrome phase of a migraine:
- when does it occur? [1]
- what are the symptoms? [8]
- Occurs hours-days before the headache
- Symptoms:
- Yawning
- Polyuria
- Depression
- Irritability
- Food cravings
- Poor concentration
- Sensitivity to light and sound
- Poor sleep
Aura phase of a migraine:
- when does it occur? [1]
- visual disturbance symptoms? [3]
- somatosensory symptoms? [2]
- motor symptoms? [4]
- speech/language symptoms? [2]
- Occurs 5-60mins before the headache
- Visual disturbance symptoms:
- chaotic distorting

- For each medication, determine efficacy at 3 months (30-50% reduction in headache days?)
- If ineffective, wean medication and try another one
- If effective, continue 6-12 months.
Describe the diagnostic criteria for a cluster headache [12]

- Pituitary apoplexy;
What are the features of a low CSF pressure headache? [3]
- Headache worse on sitting/standing up and relieved by lying down
- Results from CSF leakage
