Description
Delusional disorder is an uncommon psychiatric condition where a person experiences deeply entrenched, fixed false beliefs without the prominent hallucinations or cognitive decline seen in schizophrenia. It typically emerges in middle to late adulthood, and patients often appear completely normal and functional outside the scope of their specific delusion. The pathology is deeply rooted in abnormal cognitive processing and aberrant salience assignment within the brain.
