My dad has started having "fits" where he become disoriented, unable to focus his eyes, unable to control his motor skills, and has something that looks like a seizure. He is 57 years old, white, male. The first one was about a 1.5 years ago my dad was getting ready to fly home from vacation in Hawaii and had a seizure like "fit". He felt dizzy, weak, and was disoriented. The doctors there and when he returned home did an MRI that showed nothing unusual, Cat scan was fine, blood work and sugar levels were fine. He started feeling better so didn't pursue the issue when no test found anything. Last Thursday (April, 7th) it happened again, he couldn't focus his eyes, he said his legs were "rubbery", he was disoriented, and at one point was not able to control his head and was almost in a seizure. Mom said that when he has these "fits" both times he didn't remember where he was at parts of it. She also said that this time when they were in the ER he could answer some of the doctor's questions about age, name, address; however, other questions like who the governor or the state was, or the president of the US he drew a blank or gave the wrong answer. Again, all sorts of tests came back fine. What could be wrong with my dad? Please help.
