Q

Medication-overuse headache : Cause

A
  1. Alter brain’s pain modulation pathway
  2. Sensitises pain pathways
  3. Brain becomes more sensitive to headache triggers and amplifies pain signals

Q

Trigeminal neuralgia: Definition

A

Trigeminal neuralgia causes intense facial pain in the distribution of the trigeminal nerve, which has three branches:
* Ophthalmic (V1)
* Maxillary (V2)
* Mandibular (V3)

15
Q

Trigeminal neuralgia: Clinical features

A

Symptoms

  • Unilateral
  • Pain over 1> trigeminal nerve distribution
  • Electricity-like, shooting, stabbing or burning pain
  • Trigger : light touch, taking, eating

Onset
1. Sudden onset
2. Last seconds to hours.

16
Q

Trigeminal neuralgia: Disease association

A

More common in patients with Multiple sclerosis

17
Q

Trigeminal neuralgia: Mx

A

First line : Carbamazepine

18
Q

Cluster headaches : Definition

A
  1. Severe and unbearable unilateral headaches, usually centred around the eye.
  2. Come in clusters of attacks and then disappear for extended periods.
19
Q

Cluster headaches : Clinical features

A

1. Symptoms
typically unilateral:

  • Red, swollen and watering eye
  • Pupil constriction (miosis)
  • Eyelid drooping (ptosis)
  • Nasal discharge
  • Facial sweating

2. Onset

  • Occur in clusters of attacks and then disappear for extended periods.
  • Attacks last between 15 minutes and 3 hours.
20
Q

Cluster headaches :Incidence

A

30-50 year old male smoker.

21
Q

Cluster headaches :Management

A

Acute attacks Mx
1. Triptans (e.g., subcutaneous or intranasal sumatriptan)
2. High-flow 100% oxygen (may be kept at home)

Prophylaxis Mx
1. Verapamil is the first line for prophylaxis

22
Q

Migraine : Types

A

Migraine can be categorised into four main types:
* Migraine without aura
* Migraine with aura
* Silent migraine (migraine with aura but without a headache)
* Hemiplegic migraine

23
Q

Migraine : Clinical features

A

Migraine headaches last between 4 and 72 hours.

Typical features are:

  1. Aura - progressive symptoms occurring hours before the headache
  • Visual aura : Sparks, blurred vision, Scomata (loss of visual field)
  • Paresthesia
  • Dysphasia

Symptoms
Usually unilateral but can be bilateral
1. Moderate-severe intensity

  1. Throbbing in nature
  2. Aversion to stimuli
    * Photophobia / Phonophobia / Osmophobia
  3. Nausea and vomiting
24
Q

Hemiplegic migraines : Definition

A
  1. Migraine with unilateral limb weakness
  2. Other symptoms may include ;
    * ataxia (loss of coordination)
    * impaired consciousness.

Hemiplegic migraines can mimic a stroke or TIA. It is essential to exclude a stroke with sudden-onset hemiplegia.

25
Q

Migraine : Acute Mx

A

Acute treatment
1. First-line: offer combination therapy with

  • an Oral Triptan and an NSAID,
    or
  • an Oral Triptan and paracetamol
26
Q

Migraine : Prophylaxis Mx

A

Indicated if ;
Migraine attack have a significant impact on quality of life and daily function or very severe/prolonged.

  • First line
    1 . Propranolol
    2 . Topiramate:
    • Teratogenic - avoid in women of childbearing age
    • it can reduce the effectiveness of hormonal contraceptives
    3 . Amitriptyline
  • Second line
    1. up to 10 sessions of acupuncture over 5-8 weeks’
27
Q

Triptans : MOA

A

MOA : Stimulate serotonin receptors

various mechanisms of action, including:

  • Cranial vasoconstriction (avoid in CVS disease + HTN)
  • Inhibiting the transmission of pain signals
  • Inhibiting the release of inflammatory neuropeptides
