Q

Pathophysiology of migraines

A
  • unclear
  • possibly due to inflammation of trigeminal sensory neurones > alters way pain is processed by brain > increased sensitivity

  • often co-exists with depression + sleep disturbance
17
Q

Management of medication overuse headache

A

Discontinue medication

18

Epidemiology of cluster headaches

A
  • male > female
  • smoking history
  • 30-40 year olds
  • 1 in 1000
19
Q

Pathophysiology of cluster headaches

A
  • unkown
  • possible due to hypothalamic activation with secondary trigeminal + autonomic involvement
20
Q

Presentation of cluster headache

A
  • unilateral, around or behind eye
  • sharp, stabbing + penetrating
  • severe (often disabling)
  • occurs in clusters with periods of remission
  • usually at night
  • associated symptoms: red, watery eye, nasal congestion + ptosis
21

22
Q

Management of cluster headaches

A

Oxygen
Triptans

23
Q

Associated autonomic symptoms of cluster headaches

A

Red, watery eye
Nasal congestion
Ptosis

24
Q

Presentation of headache due to space occupying lesion

A
  • gradual, progressive
  • dull
  • mild severity
  • worse in mornings
  • worsens on leaning forwards, coughing + valsalva manoeuvre
  • associated neurological signs + symptoms
25
Q

Aggregating factors of headache due to space occupying lesion

A
  • leaning forwards
  • cough
  • valsalva manoeuvre
26
Q

Epidemiology in trigeminal neuralgia

A
  • female > male
  • 50-60 /increasing age
27
Q

Pathophysiology of trigeminal neuralgia

A
  • compression of trigeminal nerve due to loop of blood vessel (most common)
  • tumours, MS or skull base abnormalities
28
Q

Presentation of trigeminal neuralgia

A
  • unilateral
  • pain felt in 1+ division of trigeminal nerve
  • sharp, stabbing, ‘electric shock’ feeling
  • severe
  • lasting seconds - 2 mins
  • sudden onset
  • associated symptoms: tingling, numbness, radiating pain to areas of CN V distribution
29
Q

Aggravating factors of trigeminal neuralgia

A
  • light touch to face
  • eating
  • cold wind
  • combing hair
  • vibrations
30
Q

Investigations of headaches

A
  • dependent on cause
  • headache diary for chronic
  • imaging if red flags
31
Q

Treatment of headaches

A
  • depends on cause
  • simple analgesia
  • triptans for migraines
  • high low oxygen for cluster headaches
32
Q

What is temporal arteritis?

A

Vasculitis involving small + medium sized arteries of head

33
Q

Epidemiology of temporal arteritis

A
  • female > male
  • > 50 years (most commonly >75 years)
34
Q

When should temporal arteritis is considered?

A

Any patient > 50 year old with abrupt onset of headache + visual disturbance or jaw claudication

35
Q

What artery is commonly involved in temporal arteritis?

A

Superficial temporal artery

36
Q

What is an important risk of temporal arteritis?

A

Irreversible loss of vision de to ischaemia of optic nerve
