Coffee vs Alzheimer’s disease

Coffee vs Alzheimer’s disease?

  • Alzheimer’s disease (AD) is the most common type of dementia affecting more than 55 million people worldwide.
  • A new Australian study showed that:
    • Habitual coffee drinking is positively associated with the cognitive areas of executive function, attention, and the PACC score.
    • Drinking higher amounts of coffee is associated with slower cognitive decline in these areas over the course of the study (Reduce by up to 8% after 18 months)
    • Higher baseline coffee consumption is also linked to a slower accumulation of amyloid protein over the 126 months (up to a 5% decrease in cerebral beta-amyloid accumulation after 18 months)
  • Compounds other than caffeine:
    • Crude caffeine: e by-product of de-caffeinating coffee appears to be effective in partially preventing memory impairment in mice,
    • Cafestol, kahweol, and Eicosanoyl-5-hydroxytryptamide also seem to affect cognitive impairment in various animal studies.
  • Researchers say that it’s necessary to confirm these findings through more long-term observational and intervention studies.
