Q

What is the hypothesis for the pathophysiology of migraines?

Come from blood vessels that supply the brain
Migraine suffers have ‘sparkier’ reflexes that control the vessels
If they get too small or too large can cause migraine symptoms

Q

What happens to migraine sufferers when brain vessels shrink too much?

A

Some parts of brain, such as vision processing cannot deal and the result is flashing lights or zig zag lines
Whole brain can be affected- can get brain fog
Migraine ‘aura’

Q

What happens to migraine sufferers when brain vessels stretch too much?

A

If blood vessels become too big they activate receptors and the stretch causes the pain of a migraine.
When they become too stretched, can feel waves of pain in rhythm with heart beat

Q

What are the symptoms of trigeminal autonomic cephalagia?

A

Symptoms in autonomic systems on the same side, such as eye watering and redness or drooping eyelids (ptosis) as well as nasal stuffiness/runny nose

23
Q

What are examples of mass occupying lesions that will cause headaches?

A

Haemorrhage (burst blood vessel)
Tumour
Brain abcess

24
Q

Why do mass-occupying lesions cause headaches?

A

Monro-Kelly doctrine
Increasing volumes of one of the comments increasing ICP and causes headache

25
Q

What are different types of haemorrhage?

A

Epidural (between skull and dural)

A

Severe headache
Stiff neck
Fever
Confusion
Altered conscious state

27

A

Pain that radiates up and around an eye, described as tearing pain.
One eye with a droopy lid and small pupil

28
Q

What causes Horner syndrome?

A

In carotid artery dissection, if the blood vessel expands the sympathetic nerves wrapped around the vessel stop working

29
Q

What are the features of Horner syndrome?

A

It is characterized by a constricted pupil (miosis), drooping of the upper eyelid (ptosis), absence of sweating of the face (anhidrosis), and sinking of the eyeball into the bony cavity

30
Q

What types of strokes can cause headaches?

A

Both haemorrhage and ischemic strokes

31
Q

What are other CNS pathology that cause headaches?

A

Venous sinus thrombosis
Idiopathic intracranial hypertension
Post head trauma
Post lumbar puncture headache

32
Q

What is a feature of reversible cerebral vasoconstriction syndrome?

A

Recurrent sudden-onset headaches over a period of around 4 weeks

33
Q

What is an example of a primary headache with sudden onset?

A

Primary thunderclap headache
Refers to a severe and explosive headache with peak intensity at onset

34
Q

What are some red flags with headaches?

A

Thunderclap (sudden onset)
Associated focal neurological deficit- weak/numb down one side
Associated systemic features (e.g. weight loss) for cancer or meningitis
Abnormal vital signs
Papillodema
Patients > 50

35
Q

What is papillodema?

A

Papilledema is a term that is exclusively used when a disc swelling is secondary to increased intracranial pressure

36
Q

What are features of temporal vasculitis?

A

Very rare in <60
Classic symptom= acute vision loss (get small emboli to eye)
Pain in temporal area, ‘brushing hair pain’

37
Q

What is a medicine overuse headache?

A

If a patient with pain overuses pain killers, can lead to chronic headache called rebound headache (as drug starts to wear off in blood, headache comes back)

38
Q

What is a abrupt onset headache?

A

Reaches max intensity within 10 mins

39
Q

What must be done to patients with abrupt onset headache?

A

CT scan- worried about haemorrhage
Needs to be done ASAP

40
Q

Why are CT scans time sensitive?

A

The sensitivity decreases- by day 3 only 74% sensitive and a week= 50%

41
Q

What happens if the CT is negative but the history indicates a sub-arachnoid haemorrhage?

A

Do a lumbar puncture and check for bilirubin > 12 hours after onset.
If negative, exclude SAH

Tension- felt as a band or across the forehead, can last for several days. Uncomfortable and tiring, but do not usually disrupt sleep. They tend to worsen as the day progresses and are not usually made worse by physical activity
