Q

The 6th cranial nerve is the most susceptible to compression due to raised ICP. Explain why.

A

It has the longest intracranial course of any cranial nerve and so is most susceptible to compression by raised ICP

25
Describe the pathophysiology of temporal arteritis.
It is characterised by the formation of immune, inflammatory granulomas in the tunica media of medium/large arteries The inflammation resulting from the immune infiltration can lead to blockage of the lumen of arteries
26
Describe the management of temporal arteritis.
High dose corticosteroids
27
List some non-sinister causes of headache.
``` Tension-type headache Migraine Sinusitis Medication overuse headache Temperomandibular joint syndrome Trigeminal neuralgia Cluster headache ```
28
List some important questions that help you characterise non-sinister headaches.
Do you suffer from different types of headache? Are there any triggers? How disabling are the headaches? Does the patient experience an aura before headaches?
29
Describe the features of tension-type headaches.
Very common Often bifrontal across the forehead Not very disabling and there are no other features (e.g. photophobia) Stress and fatigue are common triggers
30
Describe the features of migraines.
Typically a unilateral, throbbing/pulsatile pain Often focused over one eye 1/3 of migraine sufferers experience an aura NOTE: some patients can have aura without migraine
31
What is the main treatment used for migraines?
Triptans (5HT receptor agonists) | They cause cerebral artery vasoconstriction and inhibition of trigeminal nerve transmission
32
Describe the features of sinusitis.
Facial pain along with coryzal symptoms | It is a tight pain (similar to tension-type headaches) that is often exacerbated by movement
33
What types of medication are most commonly associated with causing medication overuse headaches?
Analgesics | Migraine medications
34
Describe the features of temperomandibular joint syndrome.
Headache + dull ache in the muscles of mastication | Some patients report clicking/grinding when they move their jaw
35
Describe the features of trigeminal neuralgia.
Unilateral stabbing, sharp facial pain involving one or more divisions of the trigeminal nerve The pain lasts seconds but can occur many times in a day
36
Describe the features of cluster headaches.
Occur in clusters of about 6-12 weeks ever 1-2 years Attacks tend to occur at the same time every day Pain tends to be focused over one eye and is extremely severe
37
Which types of non-sinister headache are more common in: Women Men
``` Women Migraine TMJ syndrome Trigeminal neuralgia Men Cluster headaches ```
38
``` Even if a non-sinister headache is suspected, why is it important to check: Blood pressure H&N exam Focal neurological signs Fundoscopy ```
``` Blood pressure Malignant hypertension Head and neck examination Meningism Focal neurological signs Intracranial pathology Fundoscopy Raised ICP ```
39
List two investigations that can be used to help diagnose a subarachnoid haemorrhage.
CT head | Lumbar puncture – check for xanthochromia (present from 12 hours to 12 days after SAH)
40
What medication is regularly used in the initial management of subarachnoid haemorrhage?
Nimodipine (CCB) – this reduced spasm of the ruptured artery and prevents ischaemia
41
Describe the differences in the types of symptoms experienced in a TIA compared to an epileptic seizure.
TIA – negative symptoms (due to loss of function e.g. loss of vision, numbness, loss of power) Epilepsy – positive symptoms (due to overactivation e.g. flashing lights, muscle convulsions, paraesthesia) NOTE: migraine can produce both positive and negative symptoms
42
Describe how epileptic patients feel immediately after a seizure.
They experience a postictal phase where they will feel exhausted or confused
43
Which sinus is most commonly affected in sinusitis?
Maxillary sinus
44
Why is frontal sinusitis dangerous?
The bacteria can erode backwards into the brain and cause meningitis or brain abscesses
45
Which part of the brain do most brain tumours tend to develop in children?
Posterior cranial fossa
46
What is the most common type of brain tumour in children?
Medulloblastoma of the cerebellum
47
List three causes of subarachnoid haemorrhage.
Rupture of an arterial aneurysm (usually berry aneurysms found at the junctions of the circle of Willis) Trauma Arteriovenous malformations (e.g. rupture of haemangiomas or cerebral veins)
