15In addition to this, Multiple Sclerosis can also cause difficulty in adduction of the eyes. This occurs when a plaque forms in the Medial Longitudinal Fasciculus and presents as Nystagmus of the [blank_start]abducting[blank_end] eye and is called [blank_start]Internuclear Ophthalmoplegia[blank_end]

20Which imaging study should be conducted in order to diagnose Multiple Sclerosis?
- AMRI
- BCT
- CX-ray
21Multiple Sclerosis may also be diagnosed by means of lumbar puncture to look for inflammation in the CNS. The CSF is tested for oligoclonal bands of [blank_start]IgG[blank_end] on electrophoresis, which are inflammation markers found in 75–85% of people with Multiple Sclerosis.
- AIgG
- BIgA
- CIgE
22In the most basic sense, acute exacerbations of multiple sclerosis are treated by the following:

27If an individual is thought to be at risk of developing MS or has two relapses of the condition, disease modifying therapy can be prescribed.
Match each first line therapy to it's description.
[blank_start]Interferon Beta[blank_end]: Balances expression of pro- and anti-inflammatory agents in the brain & reduces number of inflammatory cells crossing the blood brain barrier.

30Second line treatment can also come in the rather expensive form of monoclonal antibodies. Drugs such as Natalizumab are able to reduce the ability of inflammatory immune cells to attach to and pass through the cell layers lining the
- ABlood-brain barrier

33Match the MS types to its definition:
[blank_start]Relapsing Remitting MS[blank_end] = Bouts of disease which occur months/years apart. Between these bouts there is no worsening in the patient's disability.
[blank_start]Secondary Progressive MS[blank_end] = Starts like relapsing remitting however then becomes a linear, constant attack on the myelin.
[blank_start]Primary Progressive MS[blank_end] = A constant attack on the myelin of the CNS - no bouts, just a constant disease state.
[blank_start]Progressive Relapsing[blank_end] = Bouts of disease which occur months/years apart. Between these bouts there is a progressive worsening of the condition.- AProgressive Relapsing
- BPrimary Progressive MS
- CSecondary Progressive MS
- DRelapsing Remitting MS
