thought insertion
A delusion in which the patient believes that thoughts are being placed into their mind by external forces.
Full Definition
Thought insertion is a first-rank symptom of schizophrenia characterized by the delusional belief that thoughts are being implanted in one's mind by outside agents or forces. Patients experience these inserted thoughts as foreign, not their own, and distinctly different from their natural thought processes. They may attribute these thoughts to specific entities such as government agencies, aliens, or religious figures. This phenomenon represents a severe disturbance in the sense of mental ownership and is considered a Schneiderian first-rank symptom. Thought insertion differs from thought broadcasting in that it involves thoughts coming into the mind rather than being transmitted outward.
Usage
