Abstract: We have recently shown that Alzheimer’s disease (AD) transgenic mice given a moderate level of caffeine intake (the human equivalent of 5 cups of coffee per day) are protected from development of otherwise certain cognitive impairment and have decreased hippocampal amyloid-β (Aβ) levels due to suppression of both β-secretase (BACE1) and presenilin 1 (PS1)/g-secretase expression. To determine if caffeine intake can have beneficial effects in “aged” APPsw mice already demonstrating cognitive impairment, we administered caffeine in the drinking water of 18-19 month old APPsw mice that were impaired in working memory. At 4-5 weeks into caffeine treatment, those impaired transgenic mice given caffeine (Tg/Caff) exhibited vastly superior working memory compared to the continuing impairment of control transgenic mice.
