HOUSTON -

The news about Houston Texans head coach Gary Kubiak suffering from a transient ischemic attack has many wondering if it could happen them.  

Transient ischemic attack or TIA is also called a mini-stroke. While it’s not a true stroke, it is a serious warning sign.

“The symptoms go away pretty quickly, but it's almost like a warning shot,” said Dr. Randall Wright with Mischer Neuroscience Associates. “There's something wrong and let's try to figure out what's going on.”

Symptoms of a TIA include problems with your vision, sudden confusion and dizziness.

As many as 40 percent of all people who have experienced a TIA will go on to have an actual stroke.

So what causes one of these attacks? 

“We're looking for underlying problems like high blood pressure, underlying diabetes, high cholesterol, is there narrowing in the blood vessels that put him at risk,” explained Dr. Wright.

There are also controllable risk factors, which include heart disease, obesity, smoking and alcohol use.

Many healthcare professionals agree drinking more than one or two alcoholic beverages a day can increase your risk for stroke.

“So this is the opportune time to treat and understand what may have caused the TIA and prevent the major stroke from happening down the line,” said Mr. Wright.

If you're concerned, it may be a good idea to calculate your risk and talk to your doctor.
