What is a stroke?
• Damage to part of the brain
• Caused by a problem with its blood supply
• Blood is supplied through arteries
• There is a ‘blockage’ or ‘burst’
• Usually happens quickly and strikes suddenly- brain attack
![Page 6: Stroke Helpline 0303 3033 300 stroke.org.uk Care Home Training A workshop on Stroke.](https://reader038.fdocuments.us/reader038/viewer/2022103004/56649cf55503460f949c384b/html5/thumbnails/6.jpg)

How does this happen?
Ischaemic (69% - 80%)• Death of tissue
(infarction) because of blockage by:
• Thrombosis – a solid clot of blood in artery supplying brain or
• Embolism – a clot or other substance (fat, cholesterol, blood platelets) carried from elsewhere in circulation

Stroke Helpline 0303 3033 300stroke.org.uk
How does this happen?
Haemorrhage (15% - 20%)• Bleeding in the brain• Burst blood vessel e.g.
artery• High blood pressure can
weaken artery• Bursts and damages tissue• Brain damage is the result

Transient Ischaemic Attack
• Occurs when the brain’s blood supply is briefly interrupted
• Classification: effects last no longer than 24hours from onset or the symptoms start to resolve within 1–20 minutes
• Very rarely, symptoms of a TIA are due to bleeding (haemorrhage) in the brain
• The FAST test helps people to quickly recognise the key symptoms of a TIA or stroke

Neuroplasticity
Neuroplasticity: The brain's ability to reorganise itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment

Normal muscle tone?
The amount of contraction in a group of muscles which enables smooth voluntary movement to take place

How stroke affects tone
• Low tone – muscles tend to be loose and weak, hanging limply.
• Flaccidity
• High tone – tightening of muscles, tendons and ligaments that prevents normal movement.
• Spasticity
