What increases the risk of multiple sclerosis?
low vitamin D, smoking, and obesity
What causes multiple sclerosis?
demyelination
sclerotic plaque that blocks neural transmission
What are clinical manifestations of multiple sclerosis? S&S?
Specific to area of CNS involvement
Cycles of exacerbations and remissions
S&S:
Possible immune S&S
fatigue
optic neuritis (FIRST SIGN)
trigeminal neuralgia
widespread neuromusculoskeletal (NMSK) weakness
What is the most common and disabling symptom of MS?
Fatigue
What is optic neutitis?
Unilateral and painful visual disturbances
vertigo may develop due to connection with vestibular system
What is trigeminal neuralgia?
-One of the most widely distributed nerves in the head and face
-sudden and transient shock-like pain
- typically unilateral
(MS S&S)
What can the generalized neuromusculoskeletal weakness with MS cause?
-Abnormal speech or swallowing & weak voice
- Especially balance with ataxia (Incoordination) and abnormal muscle tone = FALL RISK
- Bowel and Bladder dysfunction
- Sexual dysfunction
- cognitive dysfunction
-depression due to emotional and pathogenic changes
What percentage of MS cases present with cognitive dysfuntion?
More than 50%
What should be a part of the systems review with multiple sclerosis?
Hx and Observation
Scan
- resisted testing with multiple joint weakness
- neuro:
*cranial nerves signs (particularly
optic, vestibular, and trigeminal
nerves)
Special Test
- balance tests
- central vertigo
- Lhermitte’s sign
What is Lhermitte’s sign?
Neck flexion or cough producing spine and/or LE shock-like pain
What are PT Implications for Multiple Sclerosis? ( What kind of referral is it?)
Urgent referral
CVAs are the ___ leading cause of death
2nd
CVAs are the ________ cause of long-term disability
leading
Which type of CVA is most common?
Ischemic
What causes an ischemic CVA?
Blocked blood flow, often due to artherosclerosis
What causes an hemorrhagic CVA?
a ruptured blood vessel, often due to HTN, aneurysms, and arteriovenous malformations
What are non-modifiable risk factors for a CVA?
- age
- african americans more than european americans
- biological women due to longer life span than men
What are modifiable risk factors for a CVA?
- CV disease and HTN
- diabetes
- Lifestyle
- SAD and obesity
- lack of exercise
- tobacco use
- cocaine and possible marijuana use
What is the pathogenesis for CVAs?
Disrupted blood flow to the brain
Are stroke symptoms sudden or gradual?
Sudden onset
What determines more specific S&S with a CVA?
Region of brain
What are general CVA S&S?
- multi-segmental HEMI face and/or extremity numbness and weakness/paralysis
- visual disturbance
- speech, swallowing impaired
- severe HA, WORST Ever
- dizziness or fall
What is included in our systems review for CVA?
Hx and Observation
CV Scans
* Neuro tests: CN signs, UMN signs, Teitelbaum’s CPR for hemispheric lesion, vascular tests for carotid
What are PT implications for a CVA? (What kind of referral?)
Emergency Referral
What is the cause of Posterior Circulation Compromise?
CVA, pathological joint instabiliity, arthersclerosis, clot or embolism in carotid or vertebrobasialar veins, sudden arterial dissection, tumors
What are examples of pathological joint instability?
Collagen, genetic, and autoimmune conditions with AA subluxation
Where is the most common place for a clot or embolism with posterior circulation compromise?
Internal carotid
What causes sudden arterial dissection?
Excessive rotation/extension/Tx stress such as with a manipulation or trauma
What happens to arteries with posterior circulation compromise?
Ischemia of the arteries feeding the inner ear, brain stem, and cerebellum
What can be included with the ischemia of the arteries with posterior circulation compromise?
- Vertebrobasilar insufficiency
- Posterior cerebral arteries and their branches
What are affected functions of posterior circulation compromise?
- Inner ear / vestibular function
- brain stem houses cranial nerves and respiratory center
- Cerebellum regulates coordination
- The basilar artery most frequently supplies the trigeminal nerve
What are the 5 D’s and 3 N’s of posterior circulation compromise?
5Ds
- dysarthria
- dysphagia
- diplopia
- dizziness
- drop attacks - without loss of consciousness
& Ataxia, headache
3N’s
- Nausea
- Nystagmus
- Numbness/ paresthesias in face/extremities
What is ataxia?
Incoordination due to cerebellar disorder
** posterior circulation compromise
What is nystagmus?
Involuntary rotary eye movement creating a spinning sensation
What are PT implications for posterior circulation compromise? (What kind of referral?)
Emergency referral
Why can dizziness happen?
Vertigo, Disequilibrium, Pre syncope, Nonspecific
What is presyncope?
Near fainting/ light headedness just before LOC without illusion of spinning
What can cause dizziness?
High stress or medication
What is the pathogenesis of dizziness?
Vasoconstriction reducing posterior circulation to the brain
What are the PT implications for dizziness? ( what kind of referral?)
Emergency referral
What is vertigo?
