DID:Diagnosis & evaluation

Diagnosis
If symptoms seem to be present, the patient should first be evaluated by performing a complete medical history and physical examination. The various diagnostic tests, such as X-rays and blood tests are used to rule out physical illness or medication side effects as the cause of the symptoms. Certain conditions, including brain diseases, head injuries, drug and alcohol intoxication, and sleep deprivation, can lead to symptoms similar to those of dissociative disorders, including amnesia.

If no physical illness is found, the patient might be referred to a psychiatrist or psychologist. Psychiatrists and psychologists use specially designed interview and personality assessment tools to evaluate a person for a dissociative disorder.
