Is metabolic syndrome associated with learning and recall impairment in middle age?
These results indicate that impairments in cognitive functioning associated with metabolic syndrome and type 2 diabetes may begin as early as middle age and are primarily due to insulin resistance. These results demonstrate the importance of screening at-risk adults for insulin resistance in order to initiate lifestyle modifications to reverse or prevent these cognitive changes.
The results identify a select group of flavonoids that protect RPE cells from oxidative-stress-induced death with a high degree of potency and low toxicity. Many of these flavonoids also induce the expression of phase-2 detoxification proteins which could function to provide additional protection against oxidative stress. This select group of flavonoids and the foods that contain high levels of these compounds may have some clinical benefit for patients with retinal diseases associated with oxidative stress.
