Effects of beta-hydroxybutyrate administration on MK-801-induced schizophrenia-like behaviour in mice.

Rationale: Impaired cerebral glucose metabolism is a core pathological feature of schizophrenia. We recently demonstrated that a ketogenic diet, causing a shift from glycolysis to ketosis, normalized schizophrenia-like behaviours in an acute N-methyl-D-aspartate (NMDA) receptor antagonist model of the illness. Ketogenic diet produces the ketone body, β-hydroxybutyrate (BHB), which may serve as an alternative fuel source in its own right without a strict dietary regime.
