Q

What are the features of a Paroxysmal hemicrania and how long do they last?

A
  • Involves one-sided attacks (headaches) that have closely similar characteristics of pain and associated (autonomic) symptoms of cluster headache (CH) but symptoms tend to be much shorter
  • Lasts between 10-30 minutes, but can be as short as two minutes or as long as 45 minutes
  • They also tend to occur on average more frequently than CH (five per day or more - and sometimes up to 40 per day)

Q

What is suggestive of hemicrania continua ?

A

In HC, the pain is present 24 hours per day, 7 days per week, continuously for at least 3 months. The continuous headaches are typically 6-7/10 intensity, but with frequent worsening, usually to severe pain, as often as daily or many times per week.

The same associated autonomic symptoms can be present

Like paroxymsal hemicrania it is treated with indomethacin

As with all the TCA’s features are unilateral

Q

Whata are the features suggestive of SUNCT Syndrome?

A

Also manifests itself as a one-sided headache and is associated with the autonomici symptoms as described in cluster headache (CH)

  • S= Short lived (15-120 secs), can occur up to 30 per hour
  • U=unilateral
  • N= neuralgiaform headache
  • C= conjunctival injections
  • T= Tearing

Q

What are the characteristic features of trigeminal neuralgia ?

A
  • Intense, stabbing pain lasting seconds in the trigmenal nerve distribution
  • It is unilateral typically affecting the mandibular or maxillary divisions (CN V2,3)
17
Q

How long do symptoms of trigeminal neuralgia last and how often do they occur ?

A
  • Duration: 1sec to 90 secs
  • Frequency: 10 to 100 day
  • Bouts pain may last from a few weeks to months before remission
18
Q

What are the tiggers of trigmeninal neuralgia?

A

Triggered by touch e.g. shaving, eating, talking, dental prostheses

19
Q

What are the treatment options for trigeminal neuralgia ?

A
  • Pharmacological options - 1st line = Carbamazepine
  • Gabapentin, phenytoin, baclofen are other options
  • Surgical if pharmacology fails - abalation vs decompression
20
Q

What investigations may be done when someone presents with trigemnial neuralgia ?

A

MRI brain if any signs on examination, atypical features, a poor response to medical treatment or if surgical treatment is being consider
