According to scientists, regular consumption of a popular drink, coffee, often has a very ambiguous effect on the human brain in the long run. Frequent coffee consumption is associated with a decrease in brain volume in the future and an increased risk of dementia.
The researchers analyzed a dataset from 17,702 participants aged 37-73. They found that those who drank more than six cups of coffee a day had a 53% increased risk of dementia. At the same time, high coffee consumption is largely associated with a decrease in brain volume and a high risk of stroke.
Reference. Dementia is a degenerative brain disease that affects memory, thinking, behavior, and the ability to perform everyday tasks. Around 50 million people are diagnosed with dementia worldwide. For example, in Australia, dementia is the second leading cause of death, with about 250 cases diagnosed every day.
