Disorder (medicine)

From Wikipedia, the free encyclopedia

In medicine, a disorder is a functional abnormality or disturbance.^[1][2]

In many cases, the terms "disorder", "disease" and "illness" are used interchangeably.^[3] However, the term "disorder" is often considered more value-neutral than the term "disease", and is preferred by some patients with these conditions.^{[citation needed]}

Medical disorders can be categorized into mental disorders or physical disorders. Mental disorder is the far more common term and physical disorder is mostly used just for distinction purposes.
