Sorry about your troubles that youre experiencing at the moment.
Firstly delusions are all to do with what he believes in his head, so he may be. Id just need to hear more of his symptoms, such as does he hear voices, or does he believe the tv is communicating with him.
Id just like to say schizophrenia is not an illness that is all that bad. The name itself just comes with stigma borne from bad portrayal in the media.
What Im trying to say is schizophrenia is not an illness you need to fear if your son is diagnosed. As you see from this website, all of us schizophrenics come across as nice well adjusted individuals, and the truth is we have all learned immensely from our experiences of schizophrenia. All Im saying is that a lot of people fear the worst when they hear the diagnosis of this illness but in truth this illness is not that bad at all. It can actually be very much a life growing experience.
All Im saying is don’t get despondent. These problems will lift. People who have schizophrenia can bounce back in short periods of time. They can be poorly one day, but good the next. Anyway, all Im trying to say is don’t get too down about it.
As regards your son’s diagnosis, psychiatrists sometimes dither over giving patients labels, so this may explain the delay in diagnosing your son. This is because psychiatrists are really looking for a cluster of symptoms and they want them to be present for a period of time before they diagnose. For example, for schizophrenia to be diagnosed psychiatrist generally look for the psychotic episode to be present for at least 6 months.
Anyway, I hope things improve for you and your son. You sound like a very caring parent.
