1
Q

Define seizure and outline the two types

A

Sustained and synchronised electrical discharge in brain causing signs and symptoms

  1. Generalised tonic clonic (increased tone then jerking)
  2. Partial (focal signs, brain defences restrict activity to one part of brain)

Seizure
Loss of consciousness
Visual problems

22

Give 3 features which may be seen on examination in subarachnoid haemorrhage

A

Photophobia
Meningism
Pulmonary oedema

23
Q

What may be seen on LP in subarachnoid haemorrhage?

A

Xanthochromia: yellowing of CSF due to blood breakdown products)

24
Q

Give 2 management options in subarachnoid haemorrhage

A
  • Surgical clipping

- Endovascular e.g. coils

25
Define TIA
Transient episode of neurological dysfunction without acute infarction with resolution of signs and symptoms within 24 hours
26
Give 2 management options for TIA
Antiplatelet | Statin
27
Define multiple sclerosis
Idiopathic inflammatory demyelinating disease of CNS with 2 or more episodes of demyelination disseminated in space and time
28
Give 2 syndromes that can develop as a consequence of MS
- Optic neuritis | - Transverse myelitis
29
Give 3 symptoms of MS
- leg weakness - visual loss - urinary incontinence
30
Give 2 investigations for MS
- MRI brain and cervical spine with contrast | - LP (oligoclonal bands seen in CSF but not blood)
31
What is a pseudo-relapse of MS?
Re-emergence of previous symptoms related to old area of demyelination in context of heat or infection Can be triggered by temperature rise above 37.5
32
How are relapses of MS treated?
IV/oral methylprednisolone
33
Give one cause of each of the following: a) sudden onset headache b) hours to days onset c) 2-10 days onset d) morning headache
a) Subarachnoid b) Tension headache c) Cluster headache d) Intracranial mass
34
Give 4 important things to examine in the investigation of a headache
- BP - Palpation (skull, neck, temporal arteries) - Eyes (fundi, papilloedema) - Facial sensation
35
Using the CSF acronym, who should be imaged when presenting with a headache?
- Change in nature - Systemic symptoms or signs - Focal neurological deficit
36
Define Parkinson's disease and it's pathology
Dopaminergic neurons in the substantia nigra of basal ganglia are lost, meaning dopamine cannot be transported for motor movement. Surviving motor neurons contain Lewy bodies (made of alpha synuclein and ubiquitin proteins)
37
What are the 3 cardinal features of Parkinson's?
Resting tremor Bradykinesia Rigidity
38
Give 2 investigations of Parkinson's
- Dopaminergic agent trial | - DAT SPECT scan
39
Give 4 pharmacological management options for Parkinson's
- L-DOPA + Carbidopa - Dopamine agonist - MAO-B inhibitor - COMT inhibitor
40
Define cervical spondylosis
Arthritis of the neck occurring with age, causing discs to shrink and bony spurs to develop
41
Give 3 management options for cervical spondylosis
Physiotherapy Analgesia Steroid injection
42
Define Myasthenia Gravis
AI disease whereby antibodies block acetylcholine receptors at the post-synaptic neuromuscular junction
43
Give 2 symptoms and 1 investigation for myasthenia gravis
- Ptosis - Diplopia Serum ACh Receptor Ab
44
Give 3 management options for Myasthenia Gravis
- Pyridostigmine - Immunosuppressant - Thymectomy
45
Who is likely to suffer from myasthenia gravis?
Women in 20s | Men in 70s
46
Give 2 features of polyneuropathy affecting motor nerves
Weakness | Muscle atrophy
47
Give 2 features of polyneuropathy affecting sensory nerves
Sensory ataxia | Impaired pin prick
48
Give 2 features of polyneuropathy affecting autonomic nerves
Postural hypotension | ED
49
Define peripheral neuropathy
Mixed motor and sensory polyneuropathy, starts distally because those are the longest nerves in the body
50
What is Guillain-Barre syndrome and how is it treated?
Post-infectious inflammatory demyelinating neuropathy which ascends over days Tx: IV immunoglobulins
