Dementia is a general term used to describe diseases and conditions characterized by a decline in memory, language, problem-solving and other cognitive skills that affect a person’s ability to perform everyday activities. Alzheimer’s disease (AD) is the most common type of dementia. All dementias, AD included, are disorders closely associated with aging. As improvements in sanitation, vaccinations, hygiene, antibiotics, housing, and education have given us a better and longer life expectancy, age-associated disorders have grown significantly, making dementia a major healthcare epidemic.
