‘Prolonged aura’ last up to a week
The effects of a ‘migranous infarction’ will last longer
what is the type of migraine aura symptoms called and name the 2 types including examples of what each one affects
- Focal neurological symptoms
- Sensory visual, auditory, numbness, tingling heightened sensitivity - Motor ophthalmoplegia, hemiplegia
list the 5 sensory focal neurological symptoms of a migraine aura

- auditory
- numbness
- tingling
- heightened sensitivity
list the 2 motor focal neurological symptoms of a migraine aura

list the 4 types of symptoms that you get with a visual aura during a migraine
- Binocular and confined to one hemifield
Retinal migraine in which the symptoms are purely uniocular

- Absence of typical headache associated with migraine
what ddx will you refer a px who is suffering from a typical Aura with Non-migraine Headache and for this reason what should you do
In older individuals refer to rule out transient ischaemic attack (as some patients can also complain about slurry speech)
list the 4 possible pathophysiology reasons for a migraine
- Thought to be vascular in origin
vessel constriction corresponds to aura
vessel dilation corresponds to headache
Pain from Intra-cranial, extra-cerebral vessels - Physiological trigger unknown
- Genetic influence
many have positive family history - Many have an external trigger
tiredness, certain foods or drinks, bright lights (strobe lights)
explain 2 reasons why the pathophysiology for a migraine is thought to be vascular
- vessel constriction corresponds to aura
- vessel dilation corresponds to headache
Pain from Intra-cranial, extra-cerebral vessels

- Glare
Sun reflections, windows - Flicker
Flashlights, stroboscopes, TV or cinema - Patterns
Text
list 4 things you should do to manage/advise a patient to do who suffers from migraine
- If obvious diagnosis, letter of information to GP (good practise)
- Reassurance not life threatening not associated with serious illness exception can be young women on ‘the pill’ no known cure
