19
Q

What are the management types ofr migraines?

A

lifestyle

pharmacological therapy= acute/ aborative or long term preventative

20
Q

What are the lifestyle management advice for migraines? (5)

A

Avoid triggers
Diet
Sleep
Exercise
Mindfulness

21
Q

What is the acute/ aborative management of migraines? (4)

A
  • Paracetamol
  • NSAIDs (high dose & soluble)
  • Prokinetics
  • Triptans (5-HT1B/1D/1F receptor
    agonists)

hard and fast

22
Q

What are the long term preventative therapies for migraines? And what should be avoided?

A

> 5 days/month

“low and slow” with
doses until at optimal dose

Opiate-based and mixed analgesics should be avoided.

23
Q

What are the types of medications you can give for migraine prevention?

A

Tricyclic anti-depressants (TCA):

Serotonin and norepinephrine reuptake inhibitors (SNRIs):

Β-blockers

Serotonin antagonists

Anticonvulsants

Calcium Channel blockers

Angiotensin-converting enzyme inhibitor Angiotensin II receptor blockers

Parenteral

CGRP antibodies- new medications on the block for preventing migraines

24
Q

Are tension type headaches chronic or episodic?

25
What do patients say tension tpye headaches usually feel like?
Tight muscles around head and neck, as though head is in a vice.
26
How long do tension type headaches last, and what is their severity? And where are they in the head
Lasts 30mins (but can be hours long): – Bilateral – Mild or moderate
27
Does movement aggrevate tension type headaches?
No
28
What are the added features of tension type headaches?
No added features typically – No nausea or vomiting – No photophobia or phonophobia
29
What is the treatment of tension type headaches?
* Reassurance may suffice in the majority of patients. * Individual attacks can be treated with simple analgesics such as Aspirin or Paracetamol. * Preventative medications rarely required
30
What are cluster headaches and how long can they last?
severe unilateral pain (nop switching, but the next one can be on the other side) last 15-180 mins if untreated 1-8x a day short but come in bursts
31
What must there at least be one of for cluster headaches?
At least one of the following, ipsilaterally: - Conjunctival redness and/ or lacrimation - Nasal congestion and/ or rhinorrhoea - Eyelid oedema
32
What are other possible symptoms of cluster headaches? And what there must not be?
* Forehead and facial sweating * Miosis and/ or ptosis * A sense of restlessness or agitation * Not associated with a brain lesion on MRI
33
What is the acute treatment for cluster headaches? and why?
Triptan. Nasal or subcutaneous route High flow oxygen. Oxygen inhibits neuronal activation in the trigeminocervical complex
34
How do you prevent cluster headaches?
Verapamil (Calcium channel inhibitor) - Get an ECG first! Greater occipital nerve block
35
Are you happy with this table?
Y/ N
36
how do you investigate brain tumours?
head CT or MRI
37
typical SOCRATES for a migraine
S- unilateral O- sudden recurrence/intensification of symptoms C - pulsating/throbbing R- none A- nausea/vom, aura (lights, halluc), tingling, tinitis, paralysis, photophobia, phonophobia T - 4-72 hrs E - physical activity, foods, bad sleep, hormones S - moderate/severe
38
lifestyle recommendations for migraines
``` dietary - fresh foods, avoid MSG takeaways hormonal - OCP drink plenty of water dont have late nights or oversleep avoid caffeine ```
39
what are positive and negative auras
positive - flashes, zigzags | negative - blindspots
40
what is the SOCRATES of a tension headache
``` S - generalised, bilateral O - gradual onset usually C - dull, tight band-like R - neck/shoulders A- pericranial muscle tenderness, NO NAUSEA/vomiting/photophobia etc T - 3-4hrs E - analgesics, rest S - moderate ```
41
SOCRATES for cluster headaches
S - strictly unilateral, behind eye common, usually same side each time O- acute onset, same time of day C - excruciating, steady pain R - none A - eye watering, nose blocked, ptosis, eye redness, sweating, restlessness (autonomic features), photophobia, phonophobia T - 15min-3hr, same length each time, often nocturnal, come in clusters with long remissions E - S - worst pain ever experienced
