Some of the long-term side effects of a mini stroke, also called a transient ischemic attack, are permanent neurological damage and an increased chance of having a full-blown stroke, states Everyday Health. Patients often fail to notice these strokes and do not seek medical help until it is too late.
Mini strokes happen when a blood clot temporarily blocks the flow of blood to the brain, notes Healthline. These strokes often do not kill any brain tissue, and the side effects and symptoms of them are only temporary, lasting only a couple of minutes or a couple of hours.
During a mini stroke, patients often feel weakness on a single side of the body, also known as hemiparesis, states Healthline. This weakness often occurs in a single side of the face and an arm and a leg on the same side. Sometimes side effects of a mini stroke lead to a decrease in coordination, but other times it leads to the inability to move.
Sometimes mini stroke sufferers experience dysphasia, which is the inability to speak or understand words, notes Healthline. Patients may also have temporary blindness in a single eye, which is called transient monocular blindness. This condition can also lead patients to feel extreme aggravation when exposed to bright lights.
