Transcript of Stroke
Caused by thickening or narrowing of the arteries that carry blood to the brain
1. Ischemic: caused by blockages (clots) in one of the arteries or blood vessels supplying the brain. Build up of fatty deposits ie. Cholesterol on innner walls - atherosclerosis
Disruption of blood supply to the brain
Physical problems in one side of the body - numbness or weakness
Most strokes are caused by blockages (usually blood clots) disrupting the brain’s blood supply. These are called
Some strokes are caused by bleeds.
These are called
What is a Stroke?
TIA: Transient Ischemia Attack: partial bloackagae that quickly dissipates
Also arterial occlusions or stenosis. Stenosis is leakage or rupture of an artery.
Stroke is also more common in South Asian, African or Carribean partly because diabetes is more common in these populations
People with high blood pressure
People with high cholesterol
People with heart disease or
People that don't exercise
2. Haemorrhagic: One of the blood vessels bursting causing a bleed by high blood pressure
4. Heart disease
5. Brain aneurysms or arteriovenous malformations (AVMs)
Drooping on 1 side of the face
Slurred speech muddled words
Visual problems - blurred or loss of vision
Confusion and severe headache
In more serious events: psychological problems including depression and anxiety.
Bowel or bladder problems, incontinence
TIA's last 1-24 hours
CT Scan or MRI to determine the type of stroke you've had
It's important to know the type of stroke as the treatment differs:
Ultrasound to check for any blockages in the main arteries.
Blood pressure checks and
Blood tests to check glucose and cholesterol levels and other tests to check heart
Thrombolysis dissolves the clot in the artery - given within 4hrs of symptoms appearing
Carotid endartectomy: surgery to cut/clear the artery
Anti-coagulant treatment ie. Warfarin, Vitamin K, O2 therapy
Statins for high blood pressure
Stopping smoking and eating a healthy balanced diet are two strategies you can implement immediately to improve blood pressure and cholesterol levels
People that have had a stroke are at increased risk of having further strokes - so taking all preventative measures is seriously important.
Lack of exercise
Alcohol / Drug use
Reducing stress - increasing relaxation, stroking pets, spending quality time with friends
Increase of exercise
Cessation of alcohol / drug use
Benefit from Physiotherapy; to improve balance and vestibular function
Speech and Language therapy; helps recovery of communication skills and can help improve problems with eating and swallowing
May also benefit from Occupational Therapy; to redevelop skills you need to perform everyday activities - washing, cooking
Assistive/Adaptive Technologies; to make life easier ie. stair lift
A review should take place every 6 months
"Treatment and secondary prevention of stroke: evidence costs and effects on individuals and populations".
Acute ischaemic stroke patients should immediately start on Aspirin 300mg a day, reduced to a lower dose of 75mg after the acute phase. Smoking discouraged. High Blood pressure treated with diuretics. And co-agulated with Warfarin, Statins, Aspirin.
"Collaborative Meta-analysis of randomised trails of anti-platelets therapy for prevention of deaths, myocardial infarction, and stroke in high risk patients".
Aspirin (now reduced by half for acute stroke). For acute stroke 150mg, followed by 75-150mg daily is effective anti-platelet regime for long term use.
