Turning 40 often comes with changes in energy levels, metabolism, and health priorities—but it can also mark the beginning of a critical phase for heart and brain health. One important condition to watch out for is the mini stroke, also known as a transient ischemic attack (TIA).

Although TIAs can happen at any age, risk increases significantly after 40, especially with certain lifestyle and medical factors. And while a mini stroke doesn’t cause permanent brain damage, it’s a major warning sign that a full stroke could be on the way.

What Is a Mini Stroke?

A transient ischemic attack (TIA) is a temporary interruption of blood flow to the brain, often caused by a small clot or narrowed artery. Symptoms are stroke-like but resolve within minutes to hours, and there’s no permanent brain damage.

However, 1 in 3 people who have a TIA go on to have a full stroke, often within weeks or months.
