Q

What can be seen on examination in MS?

A
Depends on where demyelination has occurred and stage of disease:
Afferent pupillary defect
Nystagmus or abnormal eye movements
Cerebellar signs (balance ect...)
Sensory signs
Weakness
Spasticity
Hyperreflexia
Plantars extensor
27
Q

What is the diagnosis of MS?

A

Evidence of demyelination separated in time and space

28
Q

How is MS diagnosed?

A

Can be clinical or MRI based

29
Q

What criteria is used for clinical diagnosis of MS?

A

Posers criteria

30
Q

What criteria is used for MRI diagnosis of MS?

A

Macdonald criteria

31
Q

What other investigations can be done in MS apart from MRI?

A

LP

Bloods - to exclude other inflammatory conditions

32
Q

How can a LP be useful in MS diagnosis?

A

Can look at oligoclonal bands
If you have matched bands in the blood or serum then it is likely to be widespread inflammation occurring but if only present in the CSF then means it is isolated and diagnosed as MS

33
Q

What are the types of MS?

A
Relapsing Remitting 
Secondary progressive 
Primary progressive 
Sensory 
Malignant

Q

Who are prognostic indicators good for?

Q

When does primary progressive MS usually present?

A

50-60 yrs

37
Q

Are there relapses in Primary progressive MS?

A

No

38
Q

What is the prognosis for primary progressive MS?

A

Poor

39
Q

What is

Neuromyelitis Optica Spectrum Disorder?

A

Variant of MS

Inflammatory demyelination causes attacks of optic neuritis and myelitis

40
Q

What is a differential diagnosis for MS?

A

Q

What is Progressive Multifocal Leukencephalopathy (PML)?

A
