The Dopamine Hypothesis
No TL;DR found
Abstract
Other psychiatrists seem less reticent about offer ing explanations for this strange symptom. Arieti (1974) summarises thus a case originally reported by another investigator: “¿ Reitman (1951) reported a patient who thought that as a private in the army he had a dog's life. While on parade he disclosed his manifest outbreak of schizophrenia. He suddenly went on all fours and started to bark. His thought †̃¿ I am treated like a dog' became †̃¿ I am a dog', and consequently he acted as a dog.― Arieti, thus, discusses the symptom as the behav ioural manifestation of concreteness of thinking in schizophrenia. Concrete thinking seems to be the underlying mechanism suggested by Shapira & Roy (Journal, March 1988, 152, 432) when they attribute the “¿ over-representation― of the syndrome in their hospital to “¿ the proximity of the Newham Health Disrict to Barking and the Isle of Dogs―.
