Those cups of coffee that you drink every day to keep alert appear to have an extra perk – especially if you’re an older adult. A recent study monitoring the memory and thinking processes of people older than 65 found that all those with higher blood caffeine levels avoided the onset of Alzheimer’s disease in the two-to-four years of study follow-up.\u00a0 Moreover, coffee appeared to be the major or only source of caffeine for these individuals.<\/p>\n

Researchers from the University of South Florida and the University of Miami say the case control study provides the first direct evidence that caffeine\/coffee intake is associated with a reduced risk of dementia or delayed onset. Their findings appeared in the online version of an article published in June in the Journal of Alzheimer’s Disease. The collaborative study involved 124 people, ages 65 to 88, in Tampa and Miami.<\/p>\n

“These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee – about 3 cups a day – will not convert to Alzheimer’s disease – or at least will experience a substantial delay before converting to Alzheimer’s,” said study lead author Dr. Chuanhai Cao, a neuroscientist at the USF College of Pharmacy and the USF Health Byrd Alzheimer’s Institute. “The results from this study, along with our earlier studies in Alzheimer’s mice, are very consistent in indicating that moderate daily caffeine\/coffee intake throughout adulthood should appreciably protect against Alzheimer’s disease later in life.”<\/p>\n

Protection against cognitive impairment<\/strong><\/p>\n

The study shows this protection probably occurs even in older people with early signs of the disease, called mild cognitive impairment, or MCI.\u00a0 Patients with MCI already experience some short-term memory loss and initial Alzheimer’s pathology in their brains.\u00a0 Each year, about 15 percent of MCI patients progress to full-blown Alzheimer’s disease.\u00a0 The researchers focused on study participants with MCI, because many were destined to develop Alzheimer’s within a few years.<\/p>\n

Blood caffeine levels at the study’s onset were substantially lower (51 percent less) in participants diagnosed with MCI who progressed to dementia during the two-to-four year follow-up than in those whose mild cognitive impairment remained stable over the same period.<\/p>\n

No one with MCI who later developed Alzheimer’s had initial blood caffeine levels above a critical level of 1200 ng\/ml – equivalent to drinking several cups of coffee a few hours before the blood sample was drawn.\u00a0 In contrast, many with stable MCI had blood caffeine levels higher than this critical level.<\/p>\n

“We found that 100 percent of the MCI patients with plasma caffeine levels above the critical level experienced no conversion to Alzheimer’s disease during the two-to-four year follow-up period,” said study co-author Dr. Gary Arendash….<\/p>\n
