Depersonalization/Derealization Disorder
Depersonalization is a sense of detachment or unreality in relation to oneself; derealization is a similar experience involving the surroundings. In this disorder, the experiences recur or persist and cause significant distress or impairment.
What the experience can feel like
A person may feel as if they are observing themselves from outside, functioning like a robot, emotionally numb or disconnected from their body and memories. The world may seem dreamlike, flat, distant, unusually sharp or as though it is behind glass.
A crucial feature is intact reality testing: despite how convincing and frightening the sensation feels, the person knows it is an experience rather than proof that the world has literally ceased to exist. Brief episodes can occur with extreme tiredness or stress and do not by themselves establish a disorder.
Assessment matters
- Symptoms are persistent or recurrent and clearly interfere with work, relationships or everyday functioning.
- A clinician considers panic, depression, PTSD, acute stress, other dissociative or psychotic disorders and assesses whether reality testing remains intact.
- Substances, medicines, seizures, head injury and other neurological or medical causes need appropriate consideration.
Treatment and support
A clear explanation of the condition can reduce fear of ‘going mad’ or having permanent brain damage. Psychotherapy may address stress, excessive self-monitoring and gradual reconnection with ordinary activities and sensory experience.
Grounding techniques can help some people reconnect with the present, although they are not a complete treatment on their own. Panic, depression, PTSD, sleep problems or substance use are treated with their appropriate interventions.
When to seek help
Seek assessment when detachment persists, recurs, causes fear or interferes with driving, work, relationships or self-care. New symptoms after substance use, head injury or a seizure—or symptoms with weakness, fainting, severe headache, confusion or loss of reality testing—need prompt medical attention.
