Researchers found that high Coffee consumption is associated with smaller total brain volumes and an increased risk of dementia. The study was conducted at UniSA’s Australian Centre for Precision Health at SAHMRI, and a team of international researchers assessed the effects of Coffee on the brain among 17,702 people.
The participants found that those who drank more than six cups of Coffee a day had a 53% increased risk of dementia. Lead researcher and UniSA Ph.D. candidate, Kitty Pham, says that the research delivers important insights for public health. The researchers said that Coffee is one of the most popular drinks in the world. The global consumption being more than nine billion kilograms a year, people must understand any potential health implications.This is the most extensive investigation into the connections between Coffee, brain volume measurements, the risks of dementia, and the risks of stroke. It is also the largest study to consider volumetric brain imaging data and a wide range of confounding factors.
Dementia is a degenerative brain condition that affects memory, thinking, behavior, and the ability to perform everyday tasks. About 50 million people are diagnosed with the syndrome worldwide. In Australia, it is the second leading cause of death, with an estimated 250 people diagnosed each day.Stroke is a condition where the blood supply to the brain is disrupted, resulting in oxygen starvation, brain damage, and loss of function. Globally, one in four adults over the age of 25 will have a stroke in their lifetime. Data suggests that 13.7 million people will have a stroke this year, with 5.5 million dying as a result.
Prof Hyppönen said that together with other genetic evidence and a randomized controlled trial, these data strongly suggest that high Coffee consumption can adversely affect brain health. While the exact mechanisms are not known, one simple thing we can do is to keep hydrated and remember to drink a bit of water alongside that cup of Coffee.
