Stroke in Canada
-Leading neurological cause of death in Canada Prevalence
- There are between 40,000 to 50,000 strokes in Canada each year
- About 300,000 Canadians are living with the effects of stroke
- After age 55, the risk of stroke doubles every 10 years
- A stroke survivor has a 20% chance of having another stroke within 2 years
- For every 10,000 Canadian children under the age of 19, there are 6.7 strokes
Stroke in Canada
Cost
- Stroke costs the Canadian economy $2.7 billion a year
- The average acute care cost is about %27, 500 per stroke
- 58% of stroke patients return home after their stroke
- Many experience depression, as do up to 30% of caregivers

Types based on mechanism of damage (two types of strokes)
- Ischemic (most common)
- ->thrombosis (blood clot formed in the vessels of the brain)
- Embolism (blood clot formed somewhere else) - Hemorrhage (bleeding)
Ischemic Stroke
- Approx 80% of all strokes
- Blockage in artery with in brain because of blood clot or other substances
- Atherosclerosis = Narrowing of arteries caused plaque build up
Types of Ischemic Stroke
- Permanent Symptoms
2. Trainent Symptoms
Transient Ischemic Attack (TIA)
- Short-time (symptoms resolve in less than 24 hours)
- No permanent symptom
- Warning sign for impending major stroke (10-15% within 3 months)
Hemorrhagic Stroke
- Accounts for approximately 20% of cases
- Weakened blood vessel that ruptures and bleeds into surrounding brain
- Has greater mortality than ischemic stroke
- The blood accumulates and compresses the surrounding brain tissue
MRI of Ischemic and Hemorrhage
Ischemic (black in one area, acute)
Hemorrhage (white spots over more area)
How are the symptoms different?
Hemorrhagic: in addition to other stroke symptoms, will likely experience a sudden onset headache or head pain — a warning sign that might not occur during ischemic stroke.
Stroke symptoms: numbness or weakness on one side of the body or face, trouble speaking and difficulty with vision or balance.
Neurological impairments following stroke
- hemiplegia
- hemianopsia
- Aphasia
- Somatosensory deficits
- Incontinence
- Apraxia
- Depression
- Dysphagia
- Cognitive and perceptual deficits
Recovery
of every 100 people who have a stroke
- 10 recover completely (10%)
- *25 recover with a minor impairment or disability (25%)
- *40 are left with a moderate to severe impairment
- *10 are so severely disabled they require long-term care (10%)
- 15 die (15%)
*our patients
75% of 40,000 to 50,000 strokes in Canada each year = 33750 per year added to OT workload
Recover from stroke
- Brain recovery
- Neuroplasticity
- Improvement of performance components
- Adaption
Timeframe for recovery
- Golden time: first 1 to 3 months
- Gradual improvement for 1 year - up to 5 years
- Most independent in basic ADL
- Many are unable to return to work (depends on other factors)
Medical management
acute care
- Determining the cause and site
- Preventing progression
- Reducing cerebral edema
- Preventing secondary medical complications
- Treating acute symptoms
Medical management
-Acute ischemic stroke
- Restoration of blood flow
- Antithrombotics: aspirin and heparin
- Thrombolytics: dissolve the blood clots
- Thrombectomy: surgery
Interdisciplinary team approach
who are the members of the team
- Attending physician
- Resident
- Nurse
- Nutritionist
- Social worker
- Speech pathologist
- OT
When does OT start and when does it stop????

Common lines and drains in ICU
1. Foley catheter:
to drain urine, avoid clamping the catheter, bag should be at a lower level than the patient’s bladder
Common lines and drains in ICU
2. External ventricular drain:
- to drain CSF
- you can change the head of the bed or mobilize the patient, only if clamped by the nurse.
Common lines and drains in ICU
3. Intracranial pressure monitoring catheter (ICP):
measures intracranial pressure for patients who had swelling and elevation of the intracranial pressure
-Passive therapy, positioning and splinting NO ADLs at this point
Common lines and drains in ICU
4. Spinal drain to drain CSF:
when the drain is open the patient should be flat in bed
-Can do ADL and move around only if the drain is clamped
Common lines and drains in ICU
5. Intravenous line (IV):
-they are superficial. Do not put pressure on them specially avoid splinting the area
