Can my seizures an depression cause a diaper fetish?

No: Seizures or "epileptic" episodes would not cause this type of behavior to occur as a related problem. Nor should depression. You should consult your primary doctor for more information. They will likely want to refer you for more indepth evaluations or consults.

No: Seizures and depression cannot cause diaper rash. If you lose bladder and/or bowel control and do not keep yourself clean you can get such a rash.
