The Effects of Coffee Consumption on Cognition and Dementia Diseases

Abstract

Normal aging is accompanied by diminishing motor and cognitive performances that are exacerbated or accelerated in neurodegenerative diseases such as Alzheimer's disease (AD) or Parkinson's disease (PD). Coffee/ caffeine is regularly consumed by many people around the world providing a psychoactive stimulant resulting in enhanced alertness, arousal and improvement of cognitive performance. This review presents the science surrounding coffee, caffeine and its impact on cognition for the elderly. There is now considerable knowledge obtained from epidemiological evidence and animal studies, that 3 to 5 cups of caffeine-coffee improves-corrects, positively changes the trajectory of age-related neurodegenerative decline, supporting the healthy aging effects of coffee consumption for dementia prevention and AD. With time, life doesn't get better by chance -it gets better by change.
