My daughter had a 4 minute seizure in June for the first time ever.She was born premature by two months and had a twin that didn't survive. She had a cat scan done that showed she had calcification adjacent to the third ventricle, which may be in the left thalamus. The doctor ordered a MRI and the results say scattered punctate foci of increased T2 and Flair signal are noted in the supratentorial white matter and may represent the subtle sequelae of a remote insult. What does this mean. She's 21. I'm worried sick. They put her on seizure medicine but cannot explain the MRI or Catscan to us. Anybody have any ideas. I would appreciate any so I could sleep a little tonight. Thanks in advance
