Transient Ischemic Attack - TIA
Transient Ischemic Attacks must be taken seriously.
Graziosi: Transient Ischemic Attacks or TIAs often come on suddenly and the symptoms can be dramatic.
Warach: Weakness on one side of the body, speech disturbances, aphasia.
Graziosi: And, according to Dr. Steven Warach of the National Institute of Neurological Disorders and Stroke, TIAs are warning signs that something more serious can be right around the corner.
Warach: We know that patients that have TIAs, particularly those that may cause a little brain injury, are much more likely to have the big one — big stroke — over the next days and weeks.
Graziosi: Dr. Warach says knowing your risk factors, such as high blood pressure and diabetes, can help prevent TIAs.
Warach: So to have a TIA is really like a wake-up call to say better check everything especially if you already have risk factors or are on medicines.
Graziosi: Dr. Warach says since TIAs normally donít cause brain injuries, doctors must get a good clinical history on the patient to determine if the patient suffered a TIA or something more serious.
