Paper of the day: Three cups of coffee improves memory in older women
Older women who drink more than three cups of coffee a day have better memories than those who drink one cup a day or less, according to research on 7,000 subjects followed up for four years.
The study found less decline in memory in the high-caffeine consumers even after adjustment for age, education, disability, depression, high blood pressure, medication, cardiovascular disease and other chronic illness.
The benefits of coffee drinking on reducing memory decline appeared to increase with age, and are more apparent over the age of 80 than at age 65.
But the study found no effect on rates of dementia, and no apparent effects of caffeine on men's memory.
