Ischemic stroke (clots): an obstruction within a blood vessel supplying blood to the brain. The underlying condition for this type of obstruction is the development of fatty deposits lining the vessel walls
Hemorrhagic stroke (bleed): results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are intracerebral hemorrhage or subarachnoid hemorrhage.
TIA - Transient Ischemic Attack - (mini stroke): a temporary clot. Symptoms occur rapidly and last a relatively short time. Once a TIA is over there is usually no permanent damage to the brain.
The warning signs for all the above are the same. If more than one of the following are present, call 911 immediately:
- Sudden numbness or weakness of the face, arm or leg, especially on one side of the body
- Sudden confusion, trouble speaking or understanding
- Sudden trouble seeing in one or both eyes
- Sudden trouble walking, dizziness, loss of balance or coordination
- Sudden, severe headache with no known cause
