Olney and Farber present their work with N-methyl-D-aspartate (NMDA) antagonists, which are psychotogens, and propose that the structural changes described by Bogerts could be accounted for by a two-stage process. The first stage of the process would occur early in life and would culminate in the selective loss of NMDA-receptor bearing gamma-aminobutyric acid (GABA)ergic neurons and thus render the brain into a NMDA receptor hypofunctional (NRH) state. Such a loss would set the foundation for the second stage in which the neural circuits that have been altered by the loss of these GABAergic interneurons Would become activated in late adolescence but would be dysfunctional. Dysfunction of this circuit would lead to the psychopathology of schizophrenia and potentially, if severe enough, to neuronal degeneration. Thus, the changes described by Bogerts could originate partially in early life and partially in adulthood. Based on their animal model, the authors suggest studies that should be carried out in humans.
