The most common symptoms of a transient ischemic attack or a mini stroke include the sudden onset of slurred or garbled speech, blindness in one or both eyes, double vision, weakness and dizziness, according to Mayo Clinic. The patient may also experience loss of coordination and balance and numbness or paralysis in his face, leg, arm or one side of his body.
Symptoms of a transient ischemic attack may be mild or severe, and they usually last a few minutes, notes Healthline. Often, the symptoms are gone by the time the patient gets to the hospital. The most common symptom is hemiparesis, or weakness on one side of the body.
Mini strokes occur when a blood clot blocks blood flow to the brain, and the behavior of this blood clot determines the presentation of the symptoms, explains Healthline. If the blood clot occurs in the dominant brain hemisphere, the patient experiences dysphasia or speech disturbance. Another symptom is transient monocular blindness, which is temporary blindness in one eye.
Patients also report sudden confusion and difficulty recalling or understanding simple statements, says WebMD. Though TIA stroke symptoms are temporary and the mini stroke does not lead to permanent brain damage, the patient still has to contact a doctor, states Healthline. This is because a TIA stroke is a warning sign a stroke may be imminent.
