Alzheimer's disease is a dementia found in older adults that may take years to progress to the state where it's recognized as such. Its symptoms are memory loss, disorientation and personality change. The National Institute on Aging states that as many as half of those more than 85 years old may have it. With no known cure, many alternative therapies have been espoused for possibly slowing the process.
Preventive Approaches
The same recommendations for healthy diet and exercise for aging adults apply for prevention and slowing the progress of those thought to have early signs of AD. Besides plenty of raw veggies, fruit and whole grains, older adults are advised to stay active with good cardiovascular exercise. Studies show that exercising the brain prolongs mental health in potential AD patients as well. Social interaction, keeping up with current affairs and mental games--from chess to problem solving--are beneficial, according to the National Institutes of Health .
A Disappointing Alternative
Used for hundreds of years in China, ginkgo biloba plant extract has been touted as an antioxidant, anti-inflammatory, cell membrane protector and as a regulator of neurotransmitters. It's used regularly as an alternative Alzheimer's treatment in Europe. However, a study published in the November 2008 Journal of the American Medical Association showed no statistical advantage over a placebo.
Promising Possibilities
The Alzheimer's Association quoted studies of two other substances that show preliminary promise. Omega-3 fatty acids have shown reduced risk of dementia and cognitive decline in early research. Another substance, phosphatidylserine, a kind of fat, is the main component of membranes around nerve cells. In Alzheimer's disease and similar disorders, nerve cells degenerate. Anything that shows promise for regenerating those nerve cells seems to be a good subject of further study.
