Whats the difference between disorder and disease there are no details

That : That is a good question. I looked this up the definitions on line to make sure i got it right. Please note the source of each definition. Disorder - a derangement or abnormality of function. Used as a euphemism when it is not certain that the abnormality is in fact a disease, or when public relations suggest that the word disease is likely to be inflammatory or upsetting. (saunders comprehensive veterinary dictionary, 3 ed. © 2007 elsevier, inc) disease - a pathological condition of a body part, an organ, or a system resulting from various causes, such as infection, genetic defect, or environmental stress, and characterized by an identifiable group of signs or symptoms. (the american heritage® medical dictionary copyright © 2007, 2004 by houghton mifflin company. Published by houghton mifflin company. ) sometimes the word disorder is used to cover a condition when exact causes are not known.
