The symptoms of depersonalization-derealization disorder (DPDR) are typically a mixture of the symptoms from the two parts, with the specific prevalence of symptoms differing person to person.
*For more detailed examples of symptoms of depersonalization and derealization check out our posts dedicated to those topics*
It is not uncommon for people without DPDR to experience occasional disconnection (transient depersonalization), but DPDR has long-lasting symptoms.
DPDR's symptoms cause distress, with rumination and fear that something is very wrong with you being very common. Unfortunately, this fear may lead to an increase in symptoms.
The exact causes are unknown, but it is mainly believed to be brought on by trauma.
It is believed to occur in 1-2% of people, typically having symptom onset around age 16. There is a fairly equal prominence between men and women.
