MS done Flashcards
A person can have MS for…
Long long time.
Age that MS starts?
Early forties
Ninety percent make use of this DME?
Power chair
Multiple Sclerosis =
multiple areas of scarring(sclerotic tissue) or plaques
As the name does say, that there are multiple areas that are sclerotic
MS is an _________ disease that has an _______ effect.
Autoimmune,
Inflammatory.
Does MS affect the periphery or also the CNS.
Also the CNS
There is also the Walking Pill, the Walking Drug, Ampera, or 4AP, it clogs up the holes that were
made.
.
Spasms are muscular
Seizures
Can you train them to send more action potentials?
Yes
Etiology
• Interaction between several factors:
• genetic predisposition, we did say that MS is an AI disease.
• an inciting environmental antigen, the enviornment can trigger this person who is predisposed
susceptibility of the host, ??? Isn’t this just genetics?
Difference between exacerbation and pseudoexacernbation
The real deal is for 48. Hours or more, the psuedo is for less than 48 hours.
What can trigger their exacebation?
Heat.
Risk of developing MS is greater if you have a
siblingwith MS, greater risk for ♀ sibling vs. ♂ sibling
- 3% for sibling
- 5% for fraternal co-twin
- 25% for identical co-twin

Implicated Viruses, yet to be proven
Epstein-Barr, Very strong correlation • Measles Canine Distemper A virus • Human Herpesvirus-6 • Chlamydia pneumoniae
The MECCH is this.
Measles Epstein barr Chlamydia pneumoniae Canine distemper A virus Human herpes virus 6
Favorable prognostic indicators:
Female, onset before age 35, monoregional vs polyregional attacks, and complete recovery afterattacks
So females are shielded againstt he brunt of this problem, as is their symbol.
If they are young, so they have the ability to recover
If they do recover sfter attacks it shows that they area type of person that can recover well.
Adm finaly if the attack was at one area and not at mulitple areas, this can show that this person has a strong reislience to this disease.
You g strong shielded female, that has it at one area, and did recoverf rom previous attacks.
This shows that they would most likely do well.
Unfavorable prognostic indicators:
• Male, brainstem symptoms (ataxia, nystagmus, tremor, dysarthria), poor recovery after exacerba-tions , &high frequency of attacks
So the men are apnot shielded,
If their attacks is on the brainstem, a major area, if they have had attacks and they did not recover well,and they are getting attacked over and over again.
Somwhy are they not recoveri well or getting attacked over and over again? They are very suceptinpble. They would most likely get attacked again.
And men do not have that shield that women have.
So these are not causes, but signs that these types of people are more likely to have a poor prognosis.
Vitamin D defieciency is bpvery prevalent forMS.
.
• Inc. prevalence in areas farther away from the equator (>400 latitude)
So who is more inclined towards being affected by the heat, someone who has not ebeen acclimated to the heat.
Those are the people who are in the cold areas, so they are not used to the heat, and when it does get hot they csn become exacerbated.
But really we are speaking about those who seem to have a predisposition.
But anything that will alpw me to remenpber this.
So colder climates they are more likely to have ms?
Or those who are more likely to get MS live in the cold climates?
Nope, its really a cause, interetingly enough.
Suvival Rate
From 1980-1989:
!
Survival rate from 15 to 40 yrs
Currently
Almost a normal lifespan
Secondary to Better Managment of Symptoms
The answer for fatigue is not
rest, but it isworking out.
The BBB is disrupted and triggers:
• Astrogliosis
• Production of a brain antigen called glial fibrillary
acid protein (GFAP)
• GFAP causes further disruption of BBB
• Mobilizes “activated” lymphocytes & macrophages to the scene.
• Macrophages initiate destruction of myelin sheaths & cell bodies of oligodendrocytes.
• Fibrous astrocytes fill the demyelinated areas & form the glial scar or plaque.
• Cytotoxic lymphocytes and macrophages are present in the plaques, leading to edema that can have a masseffect, simulating a tumor
The successful treatment of MS exacerbations with ster-oids is in part based on the drugs’ ability
to control theedema resulting from the inflammatory response
REMYELINATION AFTER EXACERBATION:
The survival of oligodendrocytes is the factor behind re-
myelination in early attacks
In later stages of the disease, no oligodendrocytes are
preserved, and remyelination occurs only at the bordersof the plaques, if at all.
If we can promote oglidendrocyte survival, even though the myelin will get destroyed they can get rebuild.
The issue with MS is not that the myelin gets destroyed, that nothing new, but the issue is that new ones do not get rebuilt.
Typical lesions are in the
periventricular region of thelateral ventricles and the optic nerves (often a 1st lesion)
Relapsing-Remitting (RR)
Episodes of rapid, abrupt & unpredictable deteriorationwith variable degrees of recovery over time & minimal
residual disability
• Periods btw relapses are characterized by lack of dis-
ease progression
• Most common (85-90%)
• After 10-15 years, will develop into progressive MS in
30-40% of individuals
• 50% need assistive devices 15 yr post onset
• 40% with attacks rendering them nonambulatory
never regain ability to ambulate
• Characterized by clearly defined acute attacks with full recovery (A) or with sequelae & residual deficit upon
recovery (B). Periods between disease relapses are
characterized by lack of disease progression.
Primary-Progressive (PP)
Characterized by a steady progression of continuous
worsening with minor fluctuations, but without distinct periods of relapses and remissions
• Plateaus rather than remissions
• Aka relapsing-progressive
• Tends to affect people who are older at disease onset• Approximately 10%
• Characterized by disease showing progression of dis-ability from onset, without plateaus or remissions (A)
or with occasional plateaus & temporary minor im-
provements (B).
Secondary Progressive (SP)
Begins as relapsing-remitting (80%), followed by pro-
gression with or w/o occasional relapse, minor remis-
sion, or plateau
• The decline may include new neurologic symptoms,
worsening cognitive function, or other deficits.
• Begins with an initial RR course, followed by progres-sion of variable rate (A) that may also include occa-
sional relapses & minor remissions (B).
Progressive-Relapsing (PR)
• Steady progressive deterioration from onset with clear, acute relapses that may or may not resolve
• Periods between relapses are characterized by contin-ued progression
• Pace of deterioration can vary
• The least common of all MS subtypes
• Shows progression from onset but with clear acute re-
lapses with (A) or without (B) full recovery
Diagnosis?
• MRI with gadolinium – picks up new lesions
• Evoked potentials – measures conduction velocityalong visual/auditory/sensory pathways to detect
demyelinization
• CSF – inc. gamma globulin & WBCs
MRIs,
CSF,
And
evoked potentials
Overfatiguing someone is…
Something that is transient.
Because the muscle is being used, but it is rooted in the CNS
The fatigue worried about MS is about..
Laccitude, an overwhelming of fatigue, like coming out of a sauna that you are groggy and the muscles are fatigued.
Like waking up in REM sleep. The evening after a marathon is this feeling.
Do you rest for MS?
Do not push into central fatigue. This will cause them to overheat.
But push a little bit, and cool the patient down, before it becomes long lasting, there is 99% no risk.
To make the room cool to about…
70 degrees, but the harder that they are working the cooler you need it to be.
The episodes of MS is usually with no _______ recovery.
Full
A _________ tells us that the person has MS.
Ogliodendrocytes.
Before ten years ago it was a rule out procedure.
What canresent like MS?
Glutten, diet is very important, but it could make it look like it is MS, because the episodes are able to be presented in different ways.
The way to know which type of MS after the spinal tap tells you that it is MS is just throughh…
Anecdotes, that you will see the history.
With medication episodes of relapsing and renitting can happen
Very very rare!
There are side effect of MS medications, but…
The benefits outweigh the costs.
EDSS stands for
Expanded Disability Status Scale
EDSS is from
0-10. 10 is death.
EDSS is a progression, that if it is 8 then everything prior to that is…
Also true.
The EDSS works usually for alot of people, it is very rare to have the symptoms that are true by what a higher number tells you without having what the lower numbers show.
Usually they will have all the symptoms that there are before that number. Its like they progress to that number.
.
Which imaging is for MS?
MRI.
Then a spinal tap, will tell you what it is.
.
Best to get a ______ every year.
MRI
Some MDs will do a _______ _________ every year.
Spinal tap
Immunomodulators are used for _______.
.
CRAB for MS medicstions.
Copaxone, Rebif, Avonex and Betaseron
CRAB causes what?
Lower the immune system, cause flu like symptoms, and they patients will need to self administer
If a patient is taking CRABS do you need to be more mindful and will you not work with them if you are a little bit sick?
Yes, because they are extemely prone to getting sick.
Tysabri can cause…
PML, Progressive multifocal leukoencephalopathy,
People with exacerbation are on…
Corticosteroids. Hi doses for not mpre than 7 days.
During their corticoid steroid sessions is it a very good time to perform rehab?
Yes, because they are very uninflammed.
4AP((4EAminopyridine) is used for what?
MS for fatigue.
4AP((4EAminopyridine) what does it do?
Fills in the gaps.
Aderol is very common?
Yes, these medications give you a ton of energy, a lot of mental alertness.
Why is it important to know that they are on aderal or other medications that are not directly for MS?
Aderal will cause an effect on HR, it can cause a herpart attack.
When someone is on a ADERAL type of drug for energy provision, will we work with the patient?
Yes, but take vitals more often.
Medical(Management(of(Symptoms Fatigue
Amantadine((Symmetrel)
Modafinil((Provigil)
Moderate benefit in managing MS5related fatigue in some pa5tients
4AP((4EAminopyridine) for diminished conductivity poor endurance

Gabapentin+(Neurontin) is really the only treatment for neurological pain?
Yes
Baclofen and tezanidine are used for …
Spasticity of the muscles, which that can cause pain.
Seondary fatigue is true by MS?
No, it can happen to anyone.
What is the age that MS starts usually at?
40
What assistive device do many many people with MS make use of?
A power chair.
Multiple Sclerosis =
multiple areas of scarring(sclerotic tissue) or plaques
How do we take a look at these scars?
We use MRI
How often should a MRI be done for the MS population?
Once a year
Why would we want an MRI for the ms population?
To see the progression of these sclerosis.
What kind of disease is MS?
It is an autoimmune disease.
What kind of attacks does ms have?
Inflammatory
What do these attacks do to the person?
They demyelinate the nerves.
What happens when there is demylenation of the nerves?
It will slow down the saltatory conduction.
attacks, aka?
relapses, or exacerbations
Episodes of CNS inflammation called attacks, relapses, or exacerbations, resulting in:
Destruction of myelin
• Astrogliosis – glial scarring
• Destruction of oligodendrocytes
• Irreversible axonal damage
Besides lowering the production of the myelinwhat happens to the nerves?
They die
Do these older dead nerve get removed wuickly enough?
No
What happens if there is an abundance of dead nerve cells?
It impedes the conduction, like a traffic jam.
What is the walking drug?
Ampera, it amps you up, Walking Pill, the Walking Drug, Ampera, or 4AP
How does ampera help the person who has MS.
It fills in the gaps of the areas that there has been a breakdown of myelin.
Is MS a progressive disease?
Yes
Is MS progressing all the time?
Yes
So MS is a general progressive autoimmune disease but it is not always getting worse?
Yes
Can we train the nerves to send more signals?
Yes
What is one thing that we can do to have the person with MS to better be able to conduct himself?
To get more signals sent out from their nerves.
What is a first neural sign that people can notice in those who have MS?
This is optic neurosis.
What three things happen tot he eyes with MS?
Nystagmus, optic neuritis, and diplopia.
What happens to someone who has MS?
Dysarthria, if there nerves in their mouth is not good, then one would think to say that these people are not able to speak well.
What central nervous system issues will MS arise?
Fatigue, depression, cognitive Impairment, unstable mood.
Is at their mouth MS will not allow them to speak properly what will happen at the throat?
They will have a hard time to slow.
Now if there is neural damage by the musculoskeletal system, then what will we be able to see?
Spasms, weakness, ataxia.
If at the muscles there can be weakness and ataxia and spasms, then what will we be able to see at the sensations?
Diminished sensation(hypoesthesia), different sensations(paraesthesia), and pain.
What is a very unwelcomed paraesthesia?
Pain
What would happen when there is a lack neural innervation to the bowel and bladder?
There would be bowel and bladder incontinence, the muscle will not be able to keep their contents in place.
Name me a few areas that a we can see affected by MS?
Eyes, tongue, throat, muscles, sensations, central, bowel, and bladder.
Primary Progression is?
They steadily gets worse, but they do not have bouts of exacerbation.
Relapsing and remitting is?
It is like what the classic stock market charts are. The person gets worse, and then gets better, but does not get as good as they were, and then when they relapse they actually now get worse than what they were.
Should really be called remitting and relapsing, or maybe because the person gets worse, they relapse, and then they calm down, they remit. This is why it is called relapsing remitting.
Secondary remitting is what?
We see the name remitting, so we are to think of relapsing remitting, but a much worse type.
That when they have exacerbation they will actually get worse than the relapsing of the relapsing remitting.
What is an exacerbation?
When they loose function.
What is a pseudoexacerbation?
When a person looses function.
What is the difference between an exacerbation and a pseudo-exacerbation?
Exacerbation are more than 48 hours and a psuedo is less than 48 hours.
Are people with MS sensative to heat?
Yes
What type of temperature increase will bring about exacerbation?
Increase in core temperature.
Core MS.
Etiology
• Interaction between several factors:
- genetic predisposition, they have a predisposition.
- an inciting environmental antigen, the environment causes them to become activated
- susceptibility of the host, are they susceptible?
Males or females are more likey to get MS?
MS is for the Ms. This is for females.
What are the percentages of the sibling increase for MS?
3% for sibling
• 5% for fraternal co-twin
• 25% for identical co-twin
Implicated Viruses, yet to be proven
Epstein-Barr, Very strong correlation • Measles • Canine Distemper A virus • Human Herpesvirus-6 • Chlamydia pneumoniae
A very high correlational viral component to MS.
Epstein-Barr
Favorable prognostic indicators:
Female, because this is not something crazy, it is usual.
onset before age 35, they are young, strong.
monoregional vs polyregional attacks, it is not wide spread.
and complete recovery after attacks, not primary progressive, or relapsing and remitting, nor secondary remitting.
Unfavorable prognostic indicators:
Cerebellar based
• Male, it is strange so we do not think that it will fair well for the person.
brainstem symptoms (ataxia, nystagmus, tremor, dysarthria), it is central, bad sign, and this can be senses as a polyregional of some sorts, because it is at the root of all issues, even though in the body it is monoregional, but the brain is so so important that it can be mpconsidered multiregional.
poor recovery after exacerbations, & high frequency of attacks, if they are not recovering well then it is bad.
Men or women have a better prognosis?
Women
Poly or mono regional has a better prognosis?
Monoregional
If they recover well or if they do not recover well will there be a better prognosis?
A fuller recovery is a better prognosis.
Is the brain to be considered as mono or poly regional?
Poly regional
Why is the brain to be considered as poly regional?
Because the brain is like a team all put together.
Which vitamin deficiency is very prevalent ispn those with MS?
Vitamin D
Where are those who have MS more likely to have come from?
Inc. prevalence in areas farther away from the equator (>400 latitude)
Those who are further away from the equator are they to have more or less vitamin D?
Less
So those who are farther from the equator are more likey to have MS and ms have been correlated with a Vit D deficiency?
Yes
More prominent in ________, less so in ________& _________.
Caucasians, Africans and Asian
What age is the cut off to determine the local’s influence on the person’s chance to contract MS?
15
What is the survival rate for those with MS?
15-40 almost a full lifespan.
