ABNORMAL changes in the concentrations of blood glucose and its breakdown products occur following the administration of glucose in patients with schizophrenic, manic-depressive, and involutional psychoses.1 After the administration of glucose by mouth there is often a lag in the return to the fasting level of the blood glucose concentration and there is no fall below the fasting level at two or three hours. The patients often also show an excessive rise in the blood lactic and pyruvic acid concentration and a rise instead of the normal fall in the blood citric and a-ketoglutaric acid concentrations. In addition, many patients show an excessive and prolonged fall in serum inorganic phosphate level.
