A cerebral vascular accident known as stroke occurs after a blockage or rupture of a vessel that carries blood to the brain. Poor blood flow to brain cells means a lack of oxygen, which can sometimes be fatal. The number of people who recover their full physical and mental capacity after a stroke is one in ten. However, more than one half of stroke victims must learn to live with post stroke symptoms including social and functional disabilities.
Post stroke impairment may include:
- Speech and language problems
- Partial or complete paralysis of half of the body (hemiplegia)
- Impaired memory
The risk of acute damage is related to the size of the oxygen-deprived region.
Forerunner symptoms include:
- Dizziness and sudden loss of balance
- Loss of strength and / or sensitivity in one arm, one leg, half of the face or all of one side of the body
- Sudden difficulty finding or expressing words (incomprehensible sentences or words)
- Sudden loss of vision in one eye or visual field
