Aging - Memory decline, sugar control, and emotional memories

Great.....now I learn another way in which my aging brain can fail to remember - the worsening of glucose regulation with aging permits more glucose spikes which reduce blood flow to the dentate gyrus in our hippocampus (required for new memory formation). Perhaps on the more positive side, memories carry less emotion in older people, apparently because their processing moves towards frontal and away from limbic areas.
