My mom had the exact same symptoms last December. She ended up in my sisters driveway asleep at the wheel. She remembers nothing. The ER said she didn't have a stroke either. We still don't know what caused this but they did find a calcium brain tumor during her ct scan. She had that removed in February. She had one more episode after surgery and now is disabled and also applying for social security. The neuro thinks her latest episode is related to the surgery and has also tested her for Myasthenia Gravis.
Your not alone and not the only one. My mom is applying for disability as we speak and has her interview in June. I pray they approve her. She's also losing her health insurance.
