Caffeine reduces cognitive decline
As I am sipping my morning latte I am thrilled to read the results of a new study just out in Neurology that suggests that caffeine may reduce cognitive decline in women without dementia. Another gulp of coffee and I am that much smarter!
French researchers report that women who drank more than 3 cups of coffee per day had less mental decline during 4 years of follow-up, compared with those who drank a cup or less. Surprisingly, no such effect was seen in men.
Women who drank more than 3 cups a day had less decline in verbal retrieval and visiospacial memory during 4 years. Since word finding (verbal retrieval) seems to be a problem at about age 50, this is good news. The participants underwent a battery of cognitive exams at baseline, 2 years and 4 years follow-up. The results were adjusted for sociodemographic and clinical variables such as age, sex, education level, use of tobacco and alcohol and symptoms of depression.
Previous studies have suggested that caffeine, which is known to have positive effects on vigilance, attention, mood and arousal, may be neuroprotective.
So you don't like coffee? Not to worry...tea had the same effect. Another "Cup a Joe" for me.
