And they predict that by the year 2050, the number of cases will have tripled. This is a staggering number of people with dementia as well as a huge burden, both financially and emotionally, for families caring for loved ones.

Dementia is a syndrome, usually of a chronic nature, caused by a variety of brain illnesses that affect memory, thinking, behavior, and ability to perform everyday activities. Alzheimer's disease is the most common cause of dementia and possibly contributes up to 70 percent of cases, although other causes may include Parkinson's Disease, Huntington's Disease, and Multiple Sclerosis.

Early symptoms include:
