Hello, my little step brother is 12 years old, and he has been showing several of the signs of the rare disease known as Adrenoleukodystrophy (or ALD). I have been looking into this quite a bit recently, and I also noticed that he fits the criteria perfectly for Opposition Defiant Disorder (ODD). His symptoms that I noticed for him as far as ALD goes include progressive loss of hearing, unnaturally frequent tantrums, extreme defiance against anyone, slight aggressiveness towards his friends, and he has pretty bad eye sight. He doesn t have any serious symptoms like seizures or limpness on his body or anything like that, but the minor symptoms still show... What do you think?
