Having another senior moment? The cure may lie in a steaming mug of coffee. Daily consumption of drinks containing caffeine could help in the fight against dementia, a new study has claimed.

The study published in The Journals of Gerontology found there was a lower chance of dementia or cognitive impairment in older women whose caffeine consumption was above average.

The findings support other research showing that in older adults, caffeine can improve memory, which tends to peak in the morning and decline during the late afternoon,

The results go some way in supporting claims that caffeinated drinks such as coffee, tea and cola beverages have a role in halting cognitive decline.

Of these drinks, it is coffee that is the main contributing source of caffeine in the diet. The EFSA Comprehensive European Food Consumption Database shows coffee consumption is at its highest in adults at 36.5-319.4 mg per day.

When you drink coffee-or anything else that has caffeine as an ingredient-your central nervous system gets a mild jolt. The presence of caffeine in your system does a number of things. It ‘wakes up’ your brain, gets your digestive tract going, speeds up your metabolism and raises the brain levels of serotonin, a neurotransmitter that affects mood. Because caffeine is known to help release additional free fatty acids for energy, some people will drink a cup of coffee or take caffeine pills before they workout.

A typical cup of black coffee contains around 85 mg of caffeine. The exact amount depends on brewing approach, brew strength and specific coffee bean.

The study looked at the recorded caffeine consumption of a total of 6,467 women.

Differences in when dementia or cognitive impairment were diagnosed among women and their caffeine intake were assessed.

In yearly cognitive assessments that lasted up to 10 years, 388 women were diagnosed with probable dementia.

Risk factors such as age, race, education, body mass index (BMI), prior cardiovascular disease, diabetes, smoking and alcohol consumption were also taken into account.

Stimulatory Effect

Future prevalence of neurodegenerative conditions such as Alzheimer’s Disease is expected to quadruple by 2050,

The team, from the University of Wisconsin-Milwaukee, found women consuming above median levels of caffeine intake (mean intake – 261mg/day) for this group were less likely to develop incident dementia or any cognitive impairment compared to those consuming below median amounts (mean intake – 64mg/day) of caffeine for this group.
