A

Patient suddenly becomes vacant

Activity ceases

Lack of response from the patient

19
Q

What are Myoclonic Seizures?

A

Repetitive myoclonic jerks

20
Q

What are Atonic Seizures?

A

Complete loss of muscle tone

21
Q

How do Focal Seizures present?

A

Localised - symptoms specific to the location of the seizure.

Frontal - Motor symptoms

Parietal - Sensory Disturbances

Occipital - Visual Phenomena

Temporal - Aura, Automatisms, Hallucinations

22
Q

How is Epilepsy diagnosed?

A

Clinically

2 or more unprovoked seizures >24 hours apart

EEG

Bloods, CT/MRI used to exclude other causes

23
Q

How are patients with Epilepsy managed?

A

Focal - Carbamazepine & Lamotrigine

Generalised - 1) Sodium Valproate (Not in pregnancy)

2) Carbamazepine

24
Q

What are the main side-effects of anti-epileptics?

A

Psychiatric effects, Depression

Weight Gain

25

ICU

28
Q

What is Guillain Barre Syndrome?

A

Acute autoimmune demyelinating polyneuropathy affecting the PNS.

29
Q

How does Guillain-Barre present?

A

URTI/Gastroenteritis, commonly due to Campylobacter

2-3 Weeks later, a progressive peripheral neuropathy develops with symmetrical limb weakness.

Can progress to respiratory paralysis

30
Q

How is Guillain Barre investigated?

A

Nerve Conduction Studies - Decreased Conduction Velocity

Lumbar Puncture - Raised Protein, Normal Glucose

Spirometry (to monitor respiratory weakness)

31
Q

What is Hydrocephalus?

A

Excessive accumulation of CSF in the ventricles of the brain.

32
Q

What can cause Hydrocephalus?

A

Non-Communicating (CSF Flow obstruction)

Communicating (Increased Production/Reduced Absorption of CSF)

Normal Pressure (Idiopathic, chronic ventricular enlargement)

33
Q

How does Hydrocephalus present?

A

Acute Onset (Nause & Vomiting, Headache, Papilloedema)

Gradual Onset (Cognitive Impariment, Unsteady Gait, Diplopia, CN Palsies)

Normal Pressure (Cognitive Impairment, Gait Ataxia, Hyperreflexia)

34
Q

How would you investigate a suspected case of Hydrocephalus?

A

1) CT/MRI

CSF Analysis if ICP normal

35
Q

What can cause Cord Compression?

A

Trauma

Chronic Conditions - Tumours, Osteoporosis, Corticosteroids

Invertebral Disease 9Herniation)

36
Q

How does Cord Compression present?

A

Depends on the level and part of the spinal cord affected

Motor - Limb Weakness, UMN Below, LMN at the level

Sensory Loss below the level

Constipation, Urinary Retention, Erectilce Dysfunction

Acute onset if - Trauma, Disc Herniation

Chronic if - Osteoporosis, Tumours

37
Q

How would you investigate a possible case of Cord Compression?

A

X-Ray

MRI is definitive

Bloods - Calcium is important

Investigate Multiple Myeloma (calcium, ig electrophoresis, Bence Jones Proteins in the urine)
