Towards a Cannabinoid Hypothesis of Schizophrenia: Cognitive Impairments Due to Dysregulation of the Endogenous Cannabinoid System
Abstract
Cognitive impairments during psychotic episodes are assumed to be caused not only by one single putative classical neurotransmitter dysfunction but also by an impaired equilibrium of the interaction between different neurobiological generators of cognitive processes. Herein, the perceptual abnormalities induced by psychotogenic agents play a major role as tools for the understanding of model psychoses. The recently discovered cannabinoid receptor system with its endogenous ligand anandamide can be regarded as an extremely relevant regulator system, a dysfunctionality of which may explain at least one subtype of endogenous psychoses. Neuropsychological results (three-dimensional inversion illusion) in delta 9-tetrahydrocannabinol-intoxicated normal volunteers exhibit strong similarities with data acquired from patients suffering from productive schizophrenic psychoses, regarding disturbances in internal regulation of perceptual processes. The relevance of this finding to a general cognitive dysfunction concept of schizophrenic psychosis is discussed.

“other studies have suggested that the induction of “pro-psychotic” states in non-clinical populations, via, for example, acute cannabinoids (Emrich et al., 1997; Leweke et al., 1999; Koethe et al., 2006), chronic intoxication (Semple et al., 2003) or sleep deprivation (Sternemann et al., 1997), enable to experimentally reduce sensitivity to VIs.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
