TIA is a warning that a major stroke can happen which may cause permanent disability. So. an evaluation by the doctor is necessary. If you have had such symptoms.
A clot or blockage needs to be located in the carotid arteries by carotid doppler that is scanning of neck vessel and a procedure called carotid angiography. These are the main arteries supplying blood to the brain. A CT Scan and MRI of brain along with a cardiac evaluation is also needed.
