Psychedelics and schizophrenia
Javier González-Maeso and Stuart C. Sealfon
ABSTRACT
Research on psychedelics such as lysergic acid diethylamide (LSD) and dissociative drugs such as phencyclidine (PCP) and the symptoms, neurochemical abnormalities and treatment of schizophrenia have converged.
The effects of hallucinogenic drugs resemble some of the core symptoms of schizophrenia.
Some atypical antipsychotic drugs were identified by their high affinity for serotonin 5-HT2A receptors, which is also the target of LSD-like drugs.
Several effects of PCP-like drugs are strongly affected by both 5-HT2A and metabotropic glutamate 2/3 receptor modulation.
A serotonin-glutamate receptor complex in cortical pyramidal neurons has been identified that might be the target both of psychedelics and the atypical and glutamate classes of antipsychotic drugs.
Recent results on the receptor, signalling and circuit mechanisms underlying the response to psychedelic and antipsychotic drugs might lead to unification of the serotonin and glutamate neurochemical hypotheses of schizophrenia.
