The possible co-occurrence of high and low dopamine activity in schizophrenia has implications for the conceptualization of dopamine’s role in schizophrenia. However, several new findings suggest that abnormal, although not necessarily excessive, dopamine activity is an important factor in schizophrenia.

Dopamine in schizophrenia: a review and reconceptualization.

Evidence, particularly from intracellular recording studies in animals and plasma HVA measurements, suggests that neuroleptics act by reducing dopamine activity in mesolimbic dopamine neurons.

Alessandro Bertolino Epidemiologia e psichiatria sociale Post-mortem studies have shown high dopamine and HVA concentrations in various subcortical brain regions and greater than normal dopamine receptor densities in the brains of schizophrenic patients.

The authors hypothesize that schizophrenia is characterized by abnormally low prefrontal reconceptualizatlon activity causing deficit symptoms leading to excessive dopamine activity in mesolimbic dopamine neurons causing positive symptoms. A literature review Alan Boyd D. The authors discuss these findings and their implications. It would explain the concurrent presence of negative and positive symptoms.
