Q

What 4 main thigs happen in MS?

A

disruption of blood-brain barrier
leakage of inflammatory cells
destruction of oligodendrocytes and myelin sheath
disruption of nerve signals, rate of conduction of nerves is slowed down

Q

What area is potentially damaged if a patient with MS has sexual dysfunction?

A

spinal cord

17
Q

What area is potentially damaged if a patient with MS has mood problems?

A

limbic system, dopamine system, hypothalamus

18
Q

What area is potentially damaged if a patient with MS has decreased intellectual function?

A

frontal lobe

19
Q

What area is potentially damaged if a patient with MS has fatigue?

A

complex

20
Q

How long does a diagnosis for Ms take?

A

several months or more because no single test can conclusively diagnose

21
Q

What 6 events have to occur for somoene with Ms to have had a relapse?

A

clinical event of the type usually seen by MS
event must last at least 24 hours
objective findings must be present
the event is not a temporary worsening entirely due to fever or infection
to count as a distinct (new) attack, the onset of a clinical event must be at least 30 days after the onset pf any prior attack
a single paroxysmal episode does not constitute a relapse, but multiple paroxysmal events occurring over 24 hours or more can equal an attack

22
Q

What does treatment for a relapse of MS involve?

A

5-day course of steroid tablets taken at home
or
injection of steroid medicine given in hospital for 3-5 days

23
Q

What do steroids do?

A

reduce inflammation

24
Q

What are the main benefits for taking disease modifying drugs for MS?

A

fewer relapses
less severe relapses
reduce build up of disability which can occur if recovery isn’t complete form relapses

25
Q

Nam some anti-spasticity agents and relaxants

A

baclofen
tizanadine
canabis

26
Q

Name some medicines used for neuropathic pain

A

gabapentin
pregabalin
amitriptyline
carbamazepine

27
Q

Name some factors that are associated with a relatively better disease course

A

being female
being less than 40 years old when diagnoses
having fewer relapses in the first few years after diagnosis
making a complete recovery from relapses
having long intervals between relapses
having symptoms that are mainly sensory in nature
