Transient Ischemic Attack
Transient Ischemic Attack (TIA), also known as “mini-stroke,” is caused by a blood clot in the brain that is temporary (or transient). Most TIAs last about 5 minutes and it is considered a warning sign of an impending stroke. The warning signs of TIA are similar to that of a stroke: sudden numbness or weakness, especially on one side of the body, sudden confusion or trouble speaking, sudden trouble walking, sudden severe headache with no known cause and sudden trouble seeing in one or both eyes.
The best action to take if you experience any of these symptoms is to dial 9-1-1 and get to the emergency room ASAP.
