Q

What is an epidural blood patch?

A

A treatment for leaking CSF leading to lowered ICP

Put some of the patietns blood in their epidural space which will cause irritation leading to healing of the leak

Q

How do you treat tension type headache?

Study These Flashcards
A

Aspirin, paracetamol or NSAIDs

Can prevent with Tricyclic Antidepressants

18
Q

Define a Migraine?

Study These Flashcards
A

A chornic disorder of episodic attacks featuring headaches, phono/photophobia, functional disability and nausea.
And in 33%, an aura
The most frequent disabling primary headache

19
Q

What causes a migraine?

Study These Flashcards
A

We dont know the cause but it can be triggered by lots including:

  • Stress
  • Oestrogen changes e.g. menstruation
  • Diet
  • Sleep Disturbance
20
Q

What is an “aura”?

Study These Flashcards
A

A set of transient neurological symptoms lastig 15-60 minutes.
It moves from one area to the next so might appear as vision then sensory then speech problems (can be mistaken for a TIA)

21
Q

What defines a Chronic Migraine?

Study These Flashcards
A

Headaches >15 days a month for >3 months

Of which atleast 8 a month must be migraines

22
Q

How do we treat migraines?

Study These Flashcards
A

Abortive:

  • Aspirin & NSAIDs
  • Triptans

Prophylactic:

  • Propanolol
  • Anti-epileptics
  • Tricyclic Antidepressants
  • Vanlafaxin
23
Q

What should we be aware of in women with migraines?

Study These Flashcards
A

Dont give antiepileptics to those of child-bearing age as they’re teratogenic

Treat pregnant women with paracetamol or propanolol/Amitriptyline prophylactically

24
Q

Define a medication overuse headache?

Study These Flashcards
A

HEadache >15days a month developed or worsened on regular symptomatic medications

25
What causes a medication overuse headache?
- Triptans - Erots - Opiods More than 10 days a month Or simple analgesics more than 15 days a month Also caffeine overuse
26
Where do Trigeminal Autonomic Cephalagias present with pain?
In the orbital, supraorbital and temporal regions
27
What do SUNA/SUNCT stand for?
Short Lasting Unilateral Neuralgiform headache With either Autonomic symptoms or Conjunctival injection and Tearing
28
Describe a cluster headache?
- Unilateral sharp/throbbing pain - Rapid onset and 15-180 minutes duration - Incredibly severe (nicknamed "suicide Headache") - Often comes with migranous symptoms such as nausea, aura and photo/phonophobia Also remember Autonomic symptoms with all TACs
29
Why are cluster headaches called cluster headaches?
They are episodic, occuring in clusters typically lasting 1-3 months wiht anything from 1-8 a day during a bout. The bouts may be triggered by alcohol and may feature continuous background level pain They may show circadian rythmicity with bouts coming the same time every year and attacks the same time each day
30
How do you treat a cluster headache?
100% O2 ro SC sumatriptan for the attack Occipital Depomedrone injection for the bout Verapamil for prevention
31
Describe a paroxysmal hemicrania?
``` Unilateral sharp/throbbing pain Rapid onset, duration 2-30 minutes Very severe Possible Continuous bacground pain 2-40 attacks per day without circadian rythm ```
32
How do we treat Paroxysmal Hemicrania?
Prophylactic Indometacin (An NSAID)
33
Describe SUNCT?
``` Unilateral Stabbing/pulsing pain Short 10-240 second duration Triggered by wind/cold/touch/chewing 3-200 attacks a day Comes with conjunctival injection (red eye) and tears ```
34
How do we treat SUNCT?
Lamotrigine prophylactically (an anti-epileptic, same for SUNA)
35
Describe Trigeminal Neuralgia
``` Unilateral stabbing pain, unlike TACs its to the maxillary/mandibular regions. 5-10 second duration Also triggered by wind/cold/touch/chew 3-200 a day unlikely to have autonomic symptoms ```
36
How do we treat Trigeminal Neuralgia?
Carbamazepine prophylactic | Surgical intervention
37
What kind of autonomic symptoms come with the Trigeminal Autonomic Cephalagias?
- NAsal Congestion/rhinorrhoea - Eyelid Oedema - Facial Sweating - Miosis (Constricted Pupil) /Ptosis (Drooping eyelid) [Horner's Syndrome]
38
Name a tricyclic antidepressant and what headaches its used for?
Amitriptyline
39
Name a tricyclic antidepressant and what headaches its used for?
Amitriptyline - Prophylaxis of Tension Type Headaches - Prophylaxis of Migraines
40
How do you differentiate the types of TACs?
Frequency: CH = 1-8 PH = 1-40 SUNCT = 3-200 Duration: CH = 15-180 mins PH=2-30mins SUNCT = 5-240 seconds I.e. frequency and duration are inversely proportional Pain is sharp and throbbing in CHs & PHs but stabbing/pulsing or burning in SUNCT All have a very severe pain CH most likely to show circadian rythmicity
41
Summary of Treatments for Headache Types:
Thunderclap - Probably SAH - Coiling/clipping Tension Type Headache - Aspirin/NSAID/Paracetamol + Amitryptiline Migraine - Aspirin/NSAID/Triptan + Propanalol/Anti-epileptic/Amitryptiline Medication Overuse Headache - Use less meds Trigeminal Neuralgia - Carbamazepine Cluster Headache - 100% O2/SC Sumatriptan + Verapamil Paroxysmal Hemicrania - Prophylactic Indometacin NSAID SUNA/SUNCT - Anti-epileptic Lamotrigine
