Lights can set off seizures, just saying, so everything could lead back to seizures.

A little girl across the street has been diagnosed with just about everything under the sun: speech/language delay, autism, add, behavior disorder, intellectual disability, and when she was finally treated for seizure disorder one by one the other dx proved to be not so accurate although she is still understandably behind. When her seizure meds need to be adjusted, she once again has problems in school. She also has problems with heat (which isn't great in FL)
