Food Therapy: Coffee and Coffee Caffeine in Improved Complexity of Cognitive Performance?

By Kyle J. Norton

In compared to herbal medicine, food therapy even takes longer to ease the symptoms, depending to stages of treatment which directly address to the cause of disease.

Epidemiological studies do not agreed that regular coffee consumption may associate to improve cognitive function, a joint study lead by the Universidade Federal de Minas Gerais suggested.

Cognitive function is a cerebral activities in acquired knowledge, including all means and mechanisms of acquiring information.
Coffee, becoming a popular and social beverage all over the world, particular in the West, is a drink made from roast bean from the Coffea plant, native to tropical Africa and Madagascar.

In a cohort of 14,563  public service workers (35-74 years old) to examine the coffee consumption habits and cognitive function using standardized neuropsychological test, researchers at the above institutes filed the following results
1. Elderly drinking 2-3 cups/day, showed a significant improvement in the mean words remembered on learning, recall, and word recognition in compared to never/almost never groups.
2. And those drinking more than 3 cups a day exhibited an increased mean words pronounced, according to the semantic verbal fluency test in compared to the same groups.

Dr. Araújo LF, the lead author said, "coffee consumption might be slightly beneficial to memory in elderly but lacks a dose response relationship".

Further more, in 2,914 participants from the population-based Rotterdam Study (mean age: 59.3±7.2 years, 55% females) to assess coffee consumption, performed brain MRI, and cognition at baseline, researchers found that
1. Higher coffee consumption showed a lower prevalence of lacunar infarcts [odds ratio per cup increase: 0.88 (95% CI:0.79;0.98)]involved development of stroke, and smaller hippocampal volume in expression of memory ability.
2. Coffee consumption promoted better performance on the Letter Digit Substitution Task
3. But do not improved on the 15-Word Learning test delayed recall.

Dr. Araújo LF, again said, "...(there is a) complex associations between coffee consumption, brain structure, and cognition. Higher coffee consumption was cross-sectionally associated with a lower occurrence of lacunar infarcts and better executive function.

Interestingly, according to the study of coffee consumption and other baseline variables of 2606 middle-aged Finnish twins assessed in 1975 and 1981 by postal questionnaires, with after the median follow-up of 28 y, coffee consumption was not an independent predictor of cognitive performance in old age, according to the linear regression analysis.

The study also insisted that coffee drinking did not affect the risk of mild cognitive impairment or dementia, but expressed an inconsistent cognitive score.

Taking altogether, coffee and coffee caffeine can only improve performance of some cognitive function but not at a whole, particular in older population.
