Q: My eight-year-old son is under medication for seizures. Is it harmful for him to watch TV because of radiofrequency signals it emits?

The tendency for this type of seizure can be suspected if the fits occur while watching TV, playing video games, watching flashing lights, or patterns (like stripes or checks, etc).
