Here's why:
* Psychosis is a complex condition, not a single disease. It describes a break from reality, often involving hallucinations and delusions.
* Suffixes are word endings that modify the meaning of a word. While there are suffixes related to mental health (e.g., "-mania," "-phobia"), they are not directly attached to "psychosis."
Instead of a suffix, we use descriptive terms to clarify what type of psychosis someone experiences:
* Schizophrenia is a type of psychosis characterized by hallucinations, delusions, and disorganized thinking.
* Bipolar disorder can involve psychotic episodes, but the disorder itself is more complex.
* Delusional disorder involves only delusions, not hallucinations.
* Substance-induced psychosis occurs due to drug use or withdrawal.
So, the way to refer to a particular type of psychosis is to use the specific term like "schizophrenia," "bipolar disorder," etc., not a suffix.
