Small Neurological Attacks Predict Stroke, Dementia

While PCPs often overlook brief attacks of confusion or fainting and consider them to be benign, a new study published in the Journal of the American Medical Association suggests that patients who experience such transient neurological attacks (TNAs) may be at a higher risk for stroke and dementia.

A TNA is defined as are episodes that last less than 24 hours and invovle temporary neurological symptoms of the nonfocal or focal nature, or a mixture of both.

According to the study’s author, Michiel J. Bos, M.D., M.Sc.:

Our findings challenge the strong but unfounded conviction that nonfocal TNAs are harmless. On the contrary, our findings suggest that nonfocal TNAs are not only a risk factor for stroke, but also for dementia.
