Difficulties in Diagnosis

Diagnosing depersonalization disorder can be difficult.

Explaining symptoms can be difficult, and they can be misinterpreted as delusions, illusions, or hallucinations, further complicating the diagnosis.

Qualifying for a Diagnosis

Because anyone can experience passing feelings of depersonalization, diagnosis requires the episodes to be so severe that they interfere with a person's ability to function normally. Other possible causes, like drug use or mental disorders like schizophrenia, must also be ruled out. Signs of depersonalization disorder generally start in early childhood. People very rarely develop symptoms for the first time in adulthood.

Episodes can last anywhere from hours to days and keep coming back for weeks or years.

Trauma triggers many dissociative disorders, but not everyone who experiences trauma develops one. Those who do may be less reactive to emotions or have an underlying personality disorder, as well.

Approach to Treatment
