Coffee and Alzheimer's disease: scientists explained what the drink is capable of

Coffee is one of the most popular drinks in the world. A new study published in the journal Frontiers in Aging Neuroscience shows that it may also affect the risk of Alzheimer's disease.

A group of scientists studied the relationship between coffee and the risk of Alzheimer's disease. To test their theory that the drink reduces risk, the researchers recruited a group of 227 participants aged 60 and over who had not been diagnosed with cognitive decline and asked them to report their coffee drinking habits.

Follow-up examinations were then conducted every 18 months to assess cognitive abilities. In total, the observation lasted 10 years.

“We found that participants without memory impairment and with higher coffee consumption at the beginning of the study had a lower risk of developing dementia,” says Samantha Gardener, the lead author of the study. postdoctoral fellow at Edith Cowan University in Western Australia.

Results showed that participants who drank more coffee reported improvements in planning, self-control and attention. The researchers also found that higher coffee consumption slowed the build-up of amyloid protein in the brain, which is closely linked to the onset of Alzheimer's disease. More importantly, the data showed that even small increases in consumption can have significant benefits.
