"Progressive delusions" is not a standard or commonly used psychological or psychiatric term. It seems to be a combination of two concepts: "progressive" and "delusions."
Delusions: Delusions are false beliefs that persist despite clear evidence to the contrary. These beliefs are not based on reality and are often associated with mental health conditions such as schizophrenia, schizoaffective disorder, delusional disorder, or certain forms of psychosis. Delusions can take various forms, such as paranoid delusions (believing that others are plotting against you) or grandiose delusions (having an exaggerated sense of self-importance).
Progressive: The term "progressive" generally refers to something that gradually develops or advances over time. In the context of mental health, "progressive" could imply that the delusions are becoming more severe or complex as time goes on.
Since "progressive delusions" isn't a standardized term in the field of psychiatry or psychology, it's essential to be cautious when using or interpreting it. Instead, it's more accurate and helpful to describe specific types of delusions, their characteristics, and their relationship to any underlying mental health conditions. If you or someone you know is experiencing delusions or any mental health concerns, it's essential to seek professional help from a qualified mental health provider for proper assessment and support.
