My girlfriend had three strokes, in succession, two years ago (when she was 22). The night before these strokes occurred, she had a transient ischemic attack (TIA). She began speaking gibberish to her friends. She texted me later that night explaining what happened. Her friends had laughed about it because they thought she was just acting like a goofball. I had no idea these were signs of a TIA, but I told her that if it happened again she needed to go to the doctor immediately.
The next day, the right side of her body went numb. This time, she was around people who noticed something was wrong, and she was immediately rushed to the emergency room. By the next day, I had flown a thousand miles (from the location of my new job) to be with her. She couldn't remember many words. She couldn't read a clock. She did not know the answer to 3 + 0.
It turned out that, similar to the author of this article, clots had traveled through the hole in her heart and up to her brain. Luckily, she recovered fully and was back to her old self within about a month. She had surgery to fix the PFO a couple months later. The neurologist told her that nine times out of ten, the clot travels a different path, and the victim is left dead or braindead. I am so lucky. Writing about this has me in big tears.
I am going to stop writing and go hug her now.
