24
Q

What is hemicrania continua?

A

Persistent headache, without pain free periods
Unilateral pain
Moderate intensity but with exacerbations
During exacerbation may get autonomic features on side of pain - conjunctival injection, lacrimation, rhinorrhoea, miosis/ptosis
Migrainous symptoms may be present e.g nausea, light sensitivity

25
Q

How is hemicrania continua treated?

A

Indomethacin - an NSAID

Positive response to this drug is part of criteria for diagnosis

26
Q

What are primary stabbing headaches? (Ice pick)

A

Short, stabbing headaches
Very sudden and severe
Last between 5 and 30 seconds
Often occur behind ear

27
Q

Primary stabbing headaches are more common in people who have…

A

Migraines

28
Q

How are primary stabbing headaches managed?

A

Too short to treat

Migraine medication may reduce number

29
Q

What is trigeminal neuralgia?

A

Paroxysms of intense, stabbing pain lasting seconds in the trigeminal nerve distribution

30
Q

In trigeminal neuralgia, what divisions of the trigeminal nerve are typically affected?

A

Maxilllary

Mandibular

31
Q

In trigeminal neuralgia where is the pain often located?

A

Around cheek and jaw on one side typically (but can be both)

32
Q

What can happen after an attack of pain in trigeminal neuralgia?

A

Dull ache or tenderness of affected area

33
Q

In trigeminal neuralgia, there are often trigger points. Where are they and what can trigger pain?

A

Where: often around nose and mouth
What: eating, talking, washing, shaving, dental prosthesis

34
Q

In trigeminal neuralgia how frequent are the pains?

A

Varies - can be 100s per day or just occasional

Often occur in bouts with periods of normalcy

35
Q

What are some secondary causes of trigeminal neuralgia?

A

Compression of trigeminal nerve - aneurysm, tumour
MS
Zoster
Skull base malformations e.g chiari

36
Q

How is trigeminal neuralgia diagnosed?

A

Based on typical symptoms

If secondary cause possible - MRI

37
Q

How is trigeminal neuralgia managed?

A

Carbamazepine is the usual treatment - lessens nerve impulses (taken for approx one month after pain stopped)
Alternative - gabapentin, baclofen, lamotrigine

Normal painkillers do not work

If very severe and not responding to medication: deep brain stimulation
Decompression surgery - relieve pressure on the nerve
Ablative surgery

38
Q

What is another name for giant cell arteritis?

A

Temporal arteritis

39
Q

What causes GCA?

A

A form of vasculitis
Inflammation of arteries in temple and behind the eye

Autoimmune condition - large and medium size arteries undergo giant cell infiltration with fragmentation of lamina and narrowing of lumen, resulting in distal ischaemia and pain sensitive fibre stimulation

40
Q

Who typically gets GCA?

A

Over 50 (average onset is 74)
Women 2x more common
Northern Europeans

41
Q

What symptoms are associated with GCA?

A

New, and persistent headache over temple region - severe and throbbing
Tenderness over temple and scalp e.g when combing hair
Tongue/ jaw claudication (fatigue or discomfort of jaw during chewing)
Sudden vision loss in one eye - amaurosis fugax
Risk of sudden blindness
Flu like symptoms at onset - fatigue, fever, appetite loss
Weight loss
Unequal or weak pulses

Pain and stiffness in neck, hips, shoulders which is worse in morning - PMR symptoms

42
Q

GCA typically affects vessels in scalp and neck (especially temples). It can also affect…

A

Aorta and its large branches to head, arms and legs

43
Q

Why is early treatment vital in GCA?

A

Can cause blindness or stroke - so urgent referral necessary

44
Q

What do blood tests typically demonstrate in GCA?

A

ESR and CRP elevated
Platelets elevated
Increased ALP
Decreased Hb

45
Q

How is GCA diagnosed?

A

Temporal artery biopsy

  • negative biopsy does not exclude diagnosis as skin lesions occur
46
Q

How is GCA managed?

A

Immediate prednisolone 60mg/ d
Or IV methyl prednisolone is evolving vision loss or history of amaurosis fugax

Typically 2 year course then complete remission
Reduce dose once symptoms resolved and ESR reduced

With long term steroid use - PPI, bisphosphonate, calcium and vit d

47
Q

What can cause an acute single headache episode?

A 
Meningitis
Encephalitis 
SAH
Head injury 
Sinusitis 
Glaucoma - acute closed angle
48
Q

What usually causes a SAH?

A

Ruptured berry aneurysm

49
Q

Describe the headache seen in SAH

A

Sudden onset
THUNDERCLAP headache ie worst ever and explosive
Often occipital region

Other symptoms: neck stiffness, N&V, photophobia, focal signs, reduced consciousness, seizures

50
Q

What can chronic progressive headaches indicate?

A

Raised ICP

51
Q

Headaches associated with raised ICP have what features?

A

Chronic progressive
Worse on waking
