I am always upset when people say that "you have DP/DR because of anxiety, trust me, you don't have schizophrenia"
I get where you are coming from, but if you have primary DPD
then you do not overlap with schizophrenia. This isn't an opinion, rather this is well established taxonomically in the clinical literature. The medical sciences are not perfect (no academic discipline is), however mental health has been a topic of clinical analysis for centuries, and there are old folks in their labs and offices researching, reading, writing, testing and debating clinical phenomena. If you do a bit of reading into it, you will find a long history of literature about DPD that started in the late 1800s. These "old folks" are professionals who have made a clear distinction between schizophrenia and DPD in terms of formal classification but also the implicated brain structures as a result of investigation and debate that took more than a hundred years long. They emphasise that there are many differences, but a key differentiator between the two disorders is reality-testing, that of which is impaired in schizophrenia but functional in the DPD.
Now, this isn't to say that you cannot develop schizophrenia just because you have primary DPD, because I agree with you in that you potentially could just like anybody else including currently healthy people
. But it is very likely that you will not
. This is clear from the epidemiological research. Your chances are the same as a healthy person, and thats the point. Just like with anything in life that becomes subject to analysis there are always outliers, there always exist abnormalities and cases that don't lay on the trend-line, but it is very unlikely that if you have primary DPD that you will develop schizophrenia
. "But what if I am that outlier" --> this is anxiety. Just because we think something in our mind and worry about it, it doesn't necessarily become true. If we suspect psychotic symptoms then we should refer to a psychiatrist who can help diagnose us. If the clinician says theres no problem, and the people around you do not suspect anything odd about you, then you do not have a problem. You may think you do and worry about it, but thats not necessarily reality.
"because you have DP/DR it means you cannot have schizophrenia" as if DPDR was a protection against psychosis.... No, you always can have schizophrenia, and DPDR is even a symptom of it. Some people also say that that "if you worry about having schizophrenia it means you don't have it, because people who have schizophrenia don't know about it", it is just a misconception about psychosis. As a matter of fact you can have some form of schizophrenia without anosognosia
Yes, if you have schizophrenia or a psychotic disorder you may present with symptoms of DPD, but this is not a "schizophrenia-thing".
People with depression, anxiety, bipolar, even OCD can have secondary symptoms of depersonalization
, same goes for schizophrenia. I don't think anyone is arguing that DPDR is a protection against psychosis, rather that if you are worrying about developing psychosis, then you should acknowledge that you are worried. Worrying about something and actually experiencing something is two separate things.
It is dangerous to assume that everyone on this forum has primary DPD, this diagnosis is very hard to claim. For this reason, it is very important to get an accurate diagnosis from a mental health professional. You should never self-diagnose yourself with any condition, we are not capable of doing so on our own, we need the assessment of someone from the outside. This is especially the case if you have a psychosis-spectrum disorder.
How so? I do not see any overlap, and the clinicians don't either.
