my dad's confusion, forgetfulness and delusional behavior is increasing quickly and i'd like to get him to see someone who can help us as his regular doctor is of little help. what type of doctor should he see? my dad has been taking Aricept for 3 years and doesn't seem to be helping very much. also, what is the best way to discuss this with my dad without hurting his feelings? when I try talking with him it usually ends in denial on his part and feeling helpless on mine.... any suggestions would be appreciated. thanks...
