Hailey said she had no symptoms when she arrived at Eisenhower Medical Center in Rancho Mirage, California. He said they did scans, which showed that “he had a small blood clot in my brain, which they named and categorized as something called TIA.” According to the National Library of Medicine, a TIA, or transient ischemic attack, is also known as a “mini-stroke.” It occurs when the blood supply to a part of the brain is blocked for a while. Symptoms include numbness or weakness — especially on one side of the body, difficulty speaking, dizziness, loss of balance, and difficulty walking.
