Normal cerebrospinal fluid and brain glutamate levels in schizophrenia do not support the hypothesis of glutamatergic neuronal dysfunction.
A recently proposed hypothesis to explain schizophrenia is based on reports of reduced concentrations of glutamic acid in the cerebrospinal fluid (CFS) of schizophrenic patients. This hypothesis suggests that there may be a dysfunction of glutamatergic neurons in schizophrenia, with either a degeneration of these neurons, or their failure to release glutamate as a neurotransmitter. Direct measurement of glutamate levels in CSF and autopsied brain of schizophrenic patient showed no differences from glutamate levels in suitable adult control subjects. The data presented here do not offer support for the new hypothesis.
