I remember also reading some stories here of people who "recoverred" using a medical treatment (one of them was lamictal + SSRI) and the DPDR started again after they stopped. One could assume that when it was gone thanks to the treatment they did stop obsessing or worrying about it, but still it came back. So I agree, both the problem and the solution can be very different for different people.
Just to add an example it can also be caused by depression. It can also be caused by other psychiatric illnesses (like bipolar disorder, or schizophrenia, (although for the latter most people agree that it is a very frequent subject of worry for people who suffer from DPDR only and very rarely if ever a first symptom leading to a diagnosis of schizophrenia, at least according to the many experiences we can find online).
