Estrogenic Stimulation of Hypothalamic-Limbic System Metabolism in Ageing Diabetic C57BL/KsJ Mice:
"The therapeutic influences of estrogen treatment on age- and diabetes-related declines in regional brain glucose utilization (RBGU) rates were evaluated in 8- to 20-week-old female C57BL/KsJ normal ( /?) and diabetic (db/db) mice.
A gradual decline in the basal rate of brain glucose utilization was observed in all control (oil- and E-treated) groups between 8 and 20 weeks. Expression of the hyperglycemic-obese diabetes syndrome in db/db mice resulted in a significant reduction in regional brain glucose utilization RBGU rates between 8 and 20 weeks relative to control values.
These data demonstrate that the normal development-related decline in regional brain carbohydrate metabolism is accelerated by the diabetes syndrome, and that Estrogen therapy can modulate the syndrome-associated suppression of glucose utilization in steroid-sensitive CNS loci. These data suggest that the depressive influences of the diabetes syndrome on brain carbohydrate utilization rates may be therapeutically modified in recognized CNS regions possessing steroid-sequestering, metabolically responsive neurons."
I'm not as interested in the estrogen part, but rather this is further proof that the brain's failure to use carbohydrate effectively can be made worse by diabetes(carbohydrate consumption)
