</p> “Our message is quite clear,” says Dr. Robert Adams, professor of neurology at the Medical College of Georgia in August. “TIAS,while less severe than strokes in the short term, are quite dangerous and need a quick diagnosis and treatment as well as appropriate follow-up to prevent future injury.”! S. x6 n9 F8 z# Y
Unfortunately, mini-strokes are greatly under diagnosed. A study conducted for the National Stroke Association indicates that 2.5% of all adults aged 18 or older(about 4.9 million people in the U. S. )have experienced a confirmed TI A. An additional 1.2 million Americans over the age of 45, the study showed, have most likely suffered a mini-stroke without realizing it. These findings suggest that if the public knew how to spot the symptoms of stroke, especially mini-strokes, and sought prompt medical treatment, thousands of lives could be saved and major disability could be avoided.( G2 t8 i' c# T2 O.

The problem is that the symptoms of a mini-stroke are often subtle and passing. Nonetheless, there are signs you can look out for:- {- r8 {9 O' g8 @9 s* d" q' b

Along with these symptoms, researchers have identified some key indicators that increase your chances of having a full-blown stroke after a TIA: if you’re over 60, have experienced symptoms lasting longer than 10 minutes, feel weak and have a history of diabetes.

The first things you should do are quit smoking, limit your intake of alcohol to no more than a drink or two a day and increase your physical activity.
