Do you know Schizophrenia, DSM5 medical manual does, revisions

I’m kind of repeating myself from a previous post but I wanted to dwell on the disease or illness a little bit because we are categorized by symptoms, however the DSM 5 manual doesn’t mention treatment or causes. There are scholarly medical journals that do, such as, studies of subjects taking a certain medication and what the results or findings were. Also there are scholarly journals on the causes of Schizophrenia such as, genes, more then one gene, environment, and drugs. If you have sz you don’t want a depressant such as, marijuana, instead get an anti depressant drug, or my take is healthy foods and beverages, exercise releases endorphins. I think when it mentions negative symptoms it is going possibly referring to depression, and paranoia, I’m not sure.
symptom criteria changes:

Schizophrenia: Criterion A lists the five key symptoms of psychotic disorders: 1) delusions, 2) hallucinations, 3) disorganized speech, 4) disorganized or catatonic behavior, and 5) negative symptoms. In DSM-IV 2 of these 5 symptoms were required. However, only 1 of the 5 symptoms was required if delusions were bizarre or if hallucinations included a running commentary on a person’s thoughts/behavior, and/or two or more voices conversing. This exception has been removed for lack of specificity and poor reliability. This change makes intuitive sense. The notion of what constitutes “bizarre” is rather vague, and its removal reduces cultural bias. In DSM-5, two of these five symptoms are required AND at least one symptom must be one of the first three (delusions, hallucinations, disorganized speech).

Schizoaffective: Schizoaffective disorder forms a link between psychosis and mood. Previously, DSM-IV required that the mood episode be present for a substantial duration of the illness. DSM-5 requires the mood episode be present for the majority of the illness. It probably seems like splitting hairs but the change was made to improve the reliability, validity, and stability of the disorder. After all, how long is “substantial” anyway?

Delusional Disorder: The requirement that delusions be non-bizarre has been removed. A ‘delusion bizarre type’ specifier is available. Shared delusional disorder is no longer a distinct, separate disorder. It would simply be Delusional Disorder. says
Negative signs and symptoms
Negative symptoms such as social withdrawal, self-neglect, loss of motivation and initiative, emotional blunting and paucity of speech may seem less troubling to the patient, but often cause families and carers the most distress.

I have had and still do I have the five symptoms mentioned on schizophrenia, I still get hallucinations, delusions, catatonic, I had it worst before, and lack of hygiene, motivation. I was worst before. I did talk out loud at one time. I do have apathy, I’m trying to work on my facial expressions or body language or both, because it can really be difficult for family when there is no emotion or inappropriate. I have improved quite a bit. It’s a work in progress.
