The aim of the study was to examine the relationship between coffee and risk of dementia. Until now, caffeine-term effect on the central nervous system was unknown.
Prolonged study
1409 people participated in the survey. They specified how much coffee they drank in 1972, 1977, 1982 or 1987, depending on when the participants were middle-aged (average 50 years). They were divided into three groups based on their consumption of coffee:
- Small coffee: 0-2 cups per day
- Moderate amounts of coffee: 3-5 cups per day
- Lots of coffee: more than five cups per day
The first group was 15.9 percent, the second accounted for 45.6 percent and the most happy coffee accounted for 38.5 percent.
The consumer were recorded and divided into two categories: those who did not drink tea, and those who drank more than one cup a day.
The result
After an average follow-up in 21 years, all the participants, now aged 65-79 years, studied again. 61 of them were diagnosed with dementia and 48 were classified with Alzheimer’s.
It turned out that those who had been drinking coffee when they were middle-aged, had a lower risk of dementia compared with those who drank little or no coffee. Best out of it, did those who drank 3-5 cups daily. They had 65-70 percent reduced risk of dementia.
