Symptoms of mini strokes, or transient ischemic attacks, include weakness on one side of the body or in one part of the body, speech difficulties, temporary blindness in a single eye, and dizziness or lack of coordination, states Healthline. These symptoms may last for as little as one minute or for as long as 24 hours, and they may be mild or severe.
Most mini stroke symptoms present as some form of motor dysfunction, notes Healthline. Weakness may occur in the face or in one arm or leg. Speech difficulties, known as dysphagia, include the inability to speak or to recall or understand words. Vision problems include dimming or blurring of vision in one eye, the inability to read words on a white page, and sensitivity to light. In addition to dizziness and coordination issues, the individual may lose his balance, notes Mayo Clinic.
A mini stroke occurs due to a temporary interruption in the blood flow to the brain, spinal cord or retina, explains Mayo Clinic. The symptoms of a mini stroke are similar to those of a regular stroke, but a mini stroke doesn't destroy brain cells or cause permanent disability. If a person has a second mini stroke, the symptoms may be the same or different, depending on where the blockage occurs. Individuals with mini stroke symptoms require immediate medical care to prevent a full-blown stroke.
