Australian scientists have discovered the effect of coffee on the prevention of Alzheimer's disease … This is the conclusion reached by scientists at Edith Cowan University, who conducted a long-term study involving several hundred Australian residents. The experts presented their findings in an article published in the journal Frontiers in Aging Neuroscience.
The effect of coffee on the prevention of cognitive decline was revealed in 227 elderly patients who did not show signs of dementia. The participants' health was monitored for 126 months. In a subgroup of volunteers, the association between drink consumption and the accumulation of amyloid beta in the brain tissue or brain size was analyzed. Beta-amyloids are considered a major contributor to the development of Alzheimer's disease.
Patients who did not suffer from memory impairments and who drank very often coffee at the beginning of the study had a lower risk of developing mild cognitive disorders, which often precede Alzheimer's disease … Coffee also interfered with the accumulation of beta-amyloids, but did not in any way affect the degree of gray and white matter atrophy or a decrease in the volume of the hippocampus, the region of the brain responsible for the formation of long-term memory.
As noted in a press release on MedicalXpress, although Further research is needed, the data is encouraging as it demonstrates the benefits of coffee in preventing Alzheimer's.
For example, two cups of coffee will reduce the likelihood of cognitive decline by eight percent over 18 months. Over the same period, amyloid beta accumulation will decrease by five percent. However, the study did not show whether there is a difference between drinking the drink with or without caffeine, or whether the method of preparation, including the presence of milk with sugar, affects the result.
