A stroke is caused by a disruption of the blood flow to the brain. This disruption causes the death of brain cells.
There are four types of strokes:
- TIA: A transient ischemic attack is a temporary attack that may last only a few minutes or up to 24 hours. Sometimes it is so mild that it goes unnoticed. A TIA is a warning that a more serious stroke may occur.
- RIND: A reversible ischemic neurologic deficit is similar to a TIA, except the symptoms last from several days to a week. As with a TIA, the damage usually clears completely or is minimal. However, the likelihood or a major stroke is great.
- SIE: A stroke in evolution is a stroke in the process of taking place. There is a gradually increasing weakness on one side of the body.
- CS: A complete stroke exhibits all of the signs and symptoms of a stroke.
The symptoms of a stroke can vary greatly-here are some of the most common:
- dizziness
- poor coordination
- headache
- mental confusion
- aphasia (difficulty speaking)
- weakness in one hand or on one side of the body
- unconsciousness
We'll continue this lesson next week when we discuss nursing care for stroke.
