<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had an episode the other morning where I began to feel funny and had to sit down. I developed a cold sweat and could not move my arms. I was coherent through the episode. After about 20 minutes I was feeling ok. This also happened three years ago but was much worse. I lost eye sight, could not move my body, and developed a bad headache afterwards.  <response>: Hello! Welcome on Chat Doctor ! Your symptoms could be related to a TIA transient ischemic attack. Other possible causes would be low fasting glucose hypoglycemia, low blood pressure or a seizure. For this reason, I would recommend consulting with your doctor for a physical exam and some tests: - a brain MRI - complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes for possible imbalance-fasting glucose for hypoglycemia. An EEG may be needed if all the above tests result normal. Hope to have been helpful! Wishing all the best,
