There is no official treatment for DPD -so to come to the Depersonalisation research unit don´t mean your are getting a better treatment than elsewhere. What is needed to know is known. There is some test however that I would like to see. That is a qEEG examination of DP - I think it would look like one with a migraine or ADHD;lots of theta waves and a REM study of sleeping pattern. If DP is a parasympatic/self-hyponotic defence response your sleeping is properly not normal because the parasympatic system is out of balance.Something to do with the 2.vagus nerves; the dorsal vagus and lateral vagus.
