Q

Avg age of clinical onset is 30–33 years of age…but the avg age of
diagnosis is 37… why is there such a delay

A

because

1) symptoms come and go
2) MS gets mixed up with other conditions
3) symtpoms may vary person to person

Q

In 1936, only 8% of patients were reported to survive beyond 20 years
after onset of illness… but a patient can now expect to live the average
population life-expectancy minus seven years… why such a change

A

better treatment and drugs
better knownldege
and MAYBE better nutirition

25
what cells are responsible for destroying myeline sheate
T cells and monocytes

39
true or false: the symptoms of MS are the same for everyone
May differ greatly from person to person and over the course of the disease depending on the MS type and location of the lesions within the nervous system:
40
if you have an optic nerve lesion what are the signs and symptoms
blurred vision
41
if you have a branstem lesion what are the signs and symptoms
dizzinesss AND MAYBE double vision
42
if you have a cerebellum and cerebrum lesion what are the signs and symptoms
balance problems, sppech problems, uncoordinated movements and tremors
43
if you have a motor nerve tract lesion what are the signs and symptoms
muscle weakness, spasticity paralysis, bladder and bowel impairments
44
if you have a sensory nerve tract lesion what are the signs and symptoms
altered sensation, numbness, pricking, and burning sensation
45
what lesion causes blurred vision
optic nerve lesion
46
what lesion causes dizziness and may cause double vision
brainstem
47
what lesion causes balance problems, speech problems, uncoordinated movements and tremors
cerebellum and cerebrum
48
what lesion causes muscle weakness, spasticity paralysis, | bladder and bowel impairments
motor nerve tract lesion
49
what lesion causes altered sensation, numbness, prickling, | and burning sensations
sensory nerve tract lesion
50
what symtpom is common in 78% of all patients
fatigue
51
fatigue is common in what percentage of patients with MS
78
52
what are the 2 mojor symtpsoms of MS
fatigue | tremor, lack of coordinationn, unstead gait
53
when there is a MS flare up what happens to the myelin
it becomes inflammed
54
if there is scar formation after the myelin sheath becomes inflammed, what happens
permentant myelin damage and loss of function
55
if there is no scar formation after the myelin sheath becomes inflammed, what happens
complete recoverey and no loss of funciton
56
what can disease modifying therapies help with.
decrease the severity and help against he frequency of relatpses
57
MS classification is based on what two things
1) rate of disease progression | 2) frequence of flare ups
58
what are the 4 types of MS
``` relapsing/remitting MS (RRMS) Secondary progressive MS (SPMS) Primary progressive MS (PPMS) Progressive relapsing MS (PRMS) ```
59
what is the most common type of MS
relapsing/remitting MS
60
explain Relapsing Remitting MS
``` Unpredictable but clearly defined relapses (also known as attacks, exacerbations or flare-ups) during which new symptoms appear or existing ones get worse ```
61
true or false, in the period between relapses in relapsing MS, how is recovery
recovery is complete or near complete to prelapse function (remission)
62
what is more severe: relapsing MS or secondary progressive MS
secondary progressie
63
epxlain secondary progressive MS
Follows a diagnosis of RRMS. Over time, distinct relapses and remissions become less apparent and the disease begins to progress steadily (figure 2a), sometimes with plateaus
64
about half of people with relapsing MS start to worsen within what years and what does that come with
within 10-20 years of dianosis and that comes with increase levls of disability
65
true or false: meds can helo RRMS
true
66
True or fals: meds can help SPMS
true
67
which type of MS is a slow accumulattion of disability without defined relapses
Primary progressive MS. (PPMS)
68
PPMS has defined or undefined relapses
no defined relapses
69
true or false. in PPMS there are periods of remission and explain
false it May stabilize for periods of time, and even offer minor temporary improvement (figure 3b) but overall, there are no periods ofremission. A
70
what is the percentage of people with MS have primary progressive multiple scleoris
10 per cent of people diagnosed with MS have PPMS
71
what is the ratrest course of MS
progressive relapsing MS
72
what is the incidence of progressive relapsing MS
5%
73
explain progressive relatpsing MS
``` People with this form of MS experience relapses with (figure 4a) or without (figure 4b) recovery and steadily worsening disease from the beginning ```
74
true or false: meds cannot help with progressive relapsing MS
false they can
75
what is the only type of MS thaat cannot be helped by meds
primary progressie
76
can people with MS treain
yes
77
can exercise be harmful to MS
yes it can trigger flare upa
78
are kceps qualified to train clients with MS
yes
79
what does meeting the PA guidelines do for thsoe with MS
reduce fatigue improve mobility enhance elements of health related quality of life
80
who are the PA guidelines for in MS
for adults with minimal to moderate disability resulting from either relaptsing/remitting MS or progressive forms of MS
81
true or false: those with MS should consult a HC professional before behining
true
82
if you are a physically inactive person with MS how should PA be performed
activities performed at lower intensity frequence and durantionn than recommeded may bring some benefit
83
true or false: you should gradually increase duraction and frequency as progression towards meeting the guidelines
true q
84
aerobic activtity and strength training are the only activtiyes that should eb done with MS
false, it is importatnt to include daily stretch of affected joints and muscles and balance exerceises
85
how often should those with MS perform areobic and strength training
two times a wee
86
what is the time someone with MS should do aerobic exercise
at least 30 minutes durinng the workout session
87
what is the ampunt of sets and reps someone with MS should do in RT
2 sets of 10-15 reps
88
how hard/intensity should aerobic exercise be for those with MS
moderate intensity PA (5/6 on scale of 10) and causes HR to increase you should be able to talk but not sing a song during the actitvty
89
what should the inteisty be for RT for those with MS
pick a resistance (free wights, pulleys bands etc) that is heavy enough to barely, but safely, finish 10-15 reps of the last set
90
what are some good aerobic activites for those with MS
upper body exercises: arm cycling lower body exerceises: walking, leg cycling combined: eliptical =aquatic

what are some good strength training activties for those with MS
weight machines free wights cable pulleys.
92
whart are the special consideration to exrcise with MS (5)
lower level of fitness (cardio, muscle endurance and strenght and balance) fatigue heatt intolerace depression exercise does not trigger flare ups with properly managed
93
true or false and explain: those with MS have heat intolerance
true they have a body temp 0.5 higher
94
what are the 4 effects of exercise on MS
1) increases aerobic capacity 2) increases muscular sttrength and endurace 3) increase QOL 4) increase independace in ADLS
