thought insertion
Delusion where patients believe thoughts are being placed into their mind by external forces or other people.
Full Definition
Thought insertion is a first-rank symptom of schizophrenia characterized by the patient's firm belief that thoughts are being implanted in their mind by outside agents such as other people, organizations, or supernatural forces. Patients typically describe these thoughts as foreign, not their own, and often attribute them to specific sources like the government, aliens, or other individuals. This symptom represents a fundamental disruption in the sense of mental ownership and is considered pathognomonic of psychotic disorders. It differs from thought broadcasting in that the focus is on thoughts entering the mind rather than thoughts being transmitted outward.
