Researchers report sleep may be vital in supporting antioxidant processes. The study, which used short sleeping fruit flies, revealed sleep defends the body against oxidative stress, and oxidative stress in turn helps the sleep process.
Perineuronal nets (PNNs) and the neurons they enmesh can be damaged by poor diets. Excessive consumption of foods high in saturated fats and refined sugars cause inflammation and oxidative stress, resulting in cognitive decline and poor memory.

Mouse models and human postmortem brain tissue sample studies reveal a subtype of schizophrenia is related to abnormally high levels of hydrogen sulfide in the brain. Hair follicle analysis of patients with this schizophrenia subtype revealed higher expression of MPST mRNA than in those without the condition. MPST is linked to the production of hydrogen sulfide. The findings may lead to new tests to determine if a patient has the schizophrenia subtype from a simple hair sample analysis.
