Multiple sclerosis (MS)

(Inflammatory)

A

It’s inflammatory, it’s is autoimmune, immune cells (T cells and B cells) are attacking tissues that are ours

Q

Luxol fast blue stain

A

What it does is that it sticks to anywhere that there is myelin,

Histology:
Some white matter areas are blue (indicating myelin)

others have no blue stain (indicating demyelination)

Green gaps

A

Red (myelin) should cover the green (axon), the gaps with just green means that there is demyelination

Can see different stages of demyelination (more/less green visible)

Q

Ventricle expansion explained

A

Later MS, When the axons dies, the dead tissue applies resistance to ventricle,

ventricles begin to expand,

they usually trace the brain to compare how much brain volume is loss

Losing brain volume and gaining CSF is another indication of nuerodegenerstion

Q

Relapsing-Remitting
(DMT involment and both definition)

A

Relapse: active stage of inflammation

Remitting: non active stage of inflammations

Time between relapse and remitting vary

DMTs tries to keep the person in earlier RRMS phase

Symptoms starts to stay near the end of this phase ( likely when neurodegeneration is happening)

Q

How does the doctor assess pyramidal function in the video?

A

Evaluating her leg strength, such as her ability to lift her leg against gravity and push down against resistance. [2, 3]

Testing her reflexes, as brisk reflexes can indicate an issue with the pyramidal system.

Clonus, dorsiflex ankle, and fooot vibrates indicate clones, it being present is pyramidal sign

Performance fatigability
Definition

A

A reduced ability of a muscle (or group) to continue to produce contractile output (measureable), relative to initial maximal starting strength, following sustained or intermittent contractions (voluntary or otherwise). The initial strength is regained following a variable period of rest (distinct from injury).

  • BDNF (decrease but inconclusive) and VEGF(increase but inconclusive)

Chronic

Over time, BDNF goes up, the nervous system is getting this vitamin, does neuroprotection via changes to the permeability of the blood brain barrier

Q

Inflammation and Cytokines

Effects of exercise on cytokines secretion

Single intense exercise

A

Increase in pro-inflammatory cytokines

111
Q

Inflammation and Cytokines

Effects of exercise on cytokines secretion

Regular moderate exercise (chronic)

A

Long term exercise, the things that cause inflammation will go down (pro-inflammatory cytokines)

The amount of the inflammation suppressor goes up (anti-inflammatory cytokines)

112
Q

HPA Axis

Stress response

A

Chronic endurance training decreases the stress response.
- Circulating cortisol in response to stress goes down
- Circulating endorphins increase (positive for mood)

113
Q

Analogy

Why does the pathophysiology of MS lead to fatigue, and central fatigue in particular?

A

Pump: motor cortex
Hose: axon going to tire
- if there is a hole, nothing will be happening but your brain will be getting tired trying to send information (pumping)

  • getting no result from your effort
114
Q

CSEP-guidelines

Why was 4.5 chosen

A

4.5 chosen because the guidelines are recommended to be done in ADDITION to daily activities -> people with more impairment than 4.5 may be more negatively impacted by exercise (fatigued in other areas of life due to exercise)

115
Q

4.5 vs 5.0 on EDSS

A

4.5 on EDSS: fully ambulatory without aid, may have some limitation for long-term activities, can be active most of the day
- able to walk without aid or rest for 300 ml

5: walk without aid or resting for 200m, disability severe enough to impair full-day activity (hard for them to work for a full day)

116
Q

CSEP - Guidelines

Based on systematic reviews.

Who?

A

“adults (aged 18-64 years) with minimal to moderate disability (suggested 0-4.5 on EDSS scale by Kelvin although there is no actual correlation listed by CSEP) resulting from either relapsing remitting or progressive forms of multiple sclerosis”

  • audience: “people living with multiple sclerosis, their families, health care professionals and organizations that promote exercise or serve adults with multiple sclerosis”
117
Q

CSEP - Guidelines

Based on systematic reviews.

What:
● F.I.T.T.

A

Frequency: 2x/ week

Intensity: moderate (5-6 on RPE scale of 10)

Time: in sessions of 30( 60 minutes of moderate activity a week)

Type: aerobic activity

118
Q

CSEP - Guidelines

Vs

Compare with 24-hour Movement Guidelines of the general population

A

General population is 150 mins per week at moderate to vigorous intensity

Why is it less for MS
-cautious about both intensity and amount accumulated—-> no set answer for why this is reduced though

119
Q

National Multiple Sclerosis
American guildlines

A
  1. Endorse and promote benefits/safety
  2. Early evaluation (physical/occupational therapist or exercise/sport
    scientists), individualized exercise program
  3. ≥150 min/week exercise and/or ≥150 min/week lifestyle PA
  4. Progressive based on ability, preferences, safety
  5. If disability increases, referral to specialists
  6. Limited mobility, facilitated by trained assistant
120
Q

Lifestyle PA: Guidlines

A

● Daily accumulation of at least 30 min of activities

● planned/unplanned leisure, work, household, moderate-to-vigorous intensity

121
Q

Exercise

A

● Planned PA performed repeatedly
with a specific objective (e.g. improvement of fitness …)

122
Q

Rehabilitation (short term)

A

:
● Intermittent or ongoing use of interdisciplinary strategies to regain or maintain optimal physical function, promote functional independence, prevent complications, and improve QoL.

Not lifestyle changes

123
Q

O-4.5 (mild impairment)

Exercise (USA Natuonal MS society, their recommendation)

A

Exercise may temporarily worsen symptoms in patients who are heat sensitive

Aerobic: 10-30 min x 2-3/week = 20-90 min, moderate

Resistance: 2-3/week, 1-3 sets (8-15 reps), 5-10 exercises

Flexibility: daily

Neuromotor: 3-6/week, 20-60 minutes = 60-360 min

Csep has not caught up, reason why recommendations are lower

124
Q

Exercise, Body Temperature & MS

Uhthoff’s phenomenon

A

• Transient worsening of symptoms with increased core temperature

• aka heat intolerance

125
Q

Exercise, Body Temperature & MS

Thermoregulatory impairment

A

• Autonomic pathology: blunted sweating

Cooling Countermeasures
- cooling vest

126
Q

Barriers and facilitators to exercise and lifestyle physical activity.

Physical

A

• Physical environment

• Social environment

• Health condition

• Cognitive/behavioral

• Cost

Fatigue

• Time

127
Q

Barriers and facilitators to exercise and lifestyle physical activity.

Facilitators

A

• Physical environment

• Social environment

• Health condition

• Cognitive/behavioral

• Cost

• Time

128
Q

Regular lifelong exercise

A

Older at diagnosis
(Delay diagnosis)

Brain volume reduce a little

Older age when you reach secondary progressive

129
Q

Exercise after diagnosis

A

date of diagnosis is the same if you did not exercise at all

Medium brain volume

Medium delay of onset of secondary progressive

130
Q

Traditional MS course, no exercise (last slide)

A

Normal date of diagnosis

High loss of brain volume

Younger age for onset of secondary progressive
