A recent study published in the journal Alzheimer's & Dementia found that drinking more than two cups of coffee a day may help older adults reduce their risk of developing more severe dementia, according to Science Alert.
Accordingly, moderate daily caffeine intake has a positive effect on spinal fluid markers of Alzheimer's disease.
Scientists have discovered another benefit of coffee for the elderly.
Scientists from the University of Lille and the University of Paris Cité in France looked at data from a prospective study that assessed patients with mild cognitive impairment or Alzheimer's disease over five years.
Their analysis included 263 participants over the age of 70, who underwent a baseline clinical assessment and detailed surveys on their consumption of food and beverages such as coffee, chocolate, and tea to assess their daily caffeine intake. Participants also underwent MRI scans and provided blood and cerebrospinal fluid (CSF) samples.
They were divided into two groups according to the amount of caffeine consumed:
Low caffeine consumption group: Includes people who consume less than 216 mg of caffeine per day - equivalent to 1-2 cups of coffee.
High caffeine consumption group: Includes people who consume more than 216 mg of caffeine per day - that's more than 2 cups - about 3 cups of coffee per day.
The results found that the group that consumed more caffeine had a lower risk of mild cognitive impairment - with impaired memory - than the group that consumed less caffeine, according to Science Alert.
Specifically, people in the high caffeine consumption group - meaning drinking more than two cups of coffee per day - had a nearly 2.5 times lower risk of developing mild cognitive impairment, or Alzheimer's disease.
People who drink more than two cups of coffee a day have a nearly 2.5 times lower risk of developing mild cognitive impairment or Alzheimer's disease.
When looking more closely at the proteins in the participants' cerebrospinal fluid, the authors also found significant differences in the ratio and concentration of beta-amyloid protein forms in the brain — a biomarker of neurodegeneration that causes Alzheimer's symptoms.
Overall, the cerebrospinal fluid in people who consumed more caffeine had less beta-amyloid protein.
Thus, the habit of sipping coffee is not only beneficial for all ages but is also especially important for the elderly.
According to research, it is ideal to drink 2-3 cups of coffee per day, not more than 4 cups.
