Consuming Some Herbs regularly may Prevent Dementia

What is Dementia?
Dementia is a debilitating and incurable disease. However, recent studies show that regularly consuming certain herbs may help slow down or even prevent its onslaught.
People with dementia don’t just forget a friend’s name, but much of their shared history. It becomes difficult to interact with other people, think abstractly, solve problems, speak, write and even comprehend words. This chronic, progressive condition can eventually erode the ability to perform tasks as basic as getting dressed in the morning.
There are more than 60 types of dementia. The most common type is Alzheimer’s disease (AD), which afflicts more than 35 million people worldwide. Parkinson’s disease, which impairs muscle control, is another well-known type.
Non-Traditional Treatments
Worldwide, traditional healers prize selected herbs for sustaining mental function. So far, the research on herbs to enhance memory remains preliminary. As with pharmaceuticals, no herb has yet been proven to cure dementia or to prevent it from developing. Nevertheless, some experts are optimistic about particular herbs.
One such expert is Con Stough, Ph.D., a professor of neuropsychology at the Brain Sciences Institute at Swinburne University in Melbourne, Australia. Stough pointed out that, while pharmaceuticals tend to have a single action, herbs can have numerous, often synergistic actions. Because AD and other dementias have multiple causes, this herbal multitasking is important.
The herb best supported by research is ginkgo, said neuropsychopharmacologist Jerry Cott, Ph.D. In a recent trial of people with dementia, 240 mg a day of ginkgo improved memory and attention. It also relieved some of the depression, anxiety and agitation that can complicate the disease. Furthermore, a couple of studies suggest ginkgo perks up mental function in people with mild age-related memory impairment.
Can ginkgo prevent this disease? That much is still unclear. Preliminary results are now available from a much-awaited French trial called the GuidAge Study, in which 2,854 elderly people with memory problems (but no dementia) took either 120 mg of a ginkgo extract or a placebo twice a day for five years. Overall, there was no statistically significant difference in the rate of progression to dementia. However, among the people who took their ginkgo as directed for at least four years, the development of dementia was cut in half.
The herb bacopa is also gaining a reputation as a brain aid. Stough, who has done much of the research on bacopa, said the herb has several anti-Alzheimer’s actions. “There is a growing consensus indicating that bacopa and particularly CDRI08 [a special standardized extract] improve memory and cognition in non-AD patients.”
In the largest study, 107 healthy adults took either a placebo or a bacopa extract (two 150-mg tablets a day) for three months. Those who faithfully took the herb performed significantly better on memory tests. A 12-week study of healthy adults showed bacopa improved learning and memory and reduced anxiety.
Historically used to enhance vitality, Asian ginseng and American ginseng benefit the brain. Both species are adaptogens, substances that mitigate stress overload. Chronic stress can atrophy brain areas involved in memory.
Alexander Panossian, Ph.D., head of research and development at the Swedish Herbal Institute, has published numerous articles on adaptogens. He believes both that stress overload is a risk factor for dementia and that “adaptogens might be very beneficial in preventing dementia.”
While research has yet to prove that theory, two preliminary studies found that Asian ginseng, as an add-on to drug treatment, improved cognitive function in people with AD. Both Asian and American ginseng have been shown to boost memory in healthy people, as well.
Another promising adaptogen is rhodiola. Recent research by Panossian and others shows rhodiola improves symptoms of anxiety, depression and stress, and reduces mental fatigue.
Rhodiola hasn’t yet been studied in people with dementia. Nevertheless, Richard P. Brown, M.D., and Patricia Gerbarg, M.D., authors of The Rhodiola Revolution, found that rhodiola can enhance memory and cognitive function in their patients, including those with age-related memory decline and mild dementia.
Curcumin, which comes from the curry spice turmeric, is an isolated plant chemical that inhibits formation of beta-amyloid (a misfolded protein that accumulates in the brains of those with AD) and improves its clearance from the body. Studies investigating the potential benefits to AD have just begun.
Everyday Solutions
Chemically speaking, curcumin is a polyphenol, a type of chemical that may protect against certain effects of aging. Other polyphenol-rich plants Drink a cup of Green Tea a Day include red grapes, berries, pomegranates, green tea, chocolate, and coffee. Berries are rich with a neuroprotective polyphenol called anthocyanins, which can help prevent the development of Parkinson’s disease. Grape polyphenols reduce production of beta-amyloid and protect the brain cells from its toxic effects. Lab experiments also show green tea polyphenols protect against beta-amyloid-induced nerve toxicity. People who drink green tea have a reduced risk of dementia, including AD and Parkinson’s.
Research has yet to prove that changing one’s lifestyle reduces the risk of dementia. However, several strategies have at least preliminary support:
Diet matters. Whereas diets high in saturated fat increase dementia risk, those replete with vegetables and fish lower it. The Mediterranean diet, which emphasizes fruits, vegetables, fish, nuts and olive oil, seems to protect against AD and slow the rate of age-related cognitive decline.
Stay active. In a new study of 120 older adults, an aerobic training program increased the size of the hippocampus (a brain region that shrinks some with advancing age and more dramatically in AD) and improved spatial memory.
Use it or lose it. Spending more time on intellectual activities is associated with a reduced probability of AD. Some research shows that memory exercises and less-structured intellectual pursuits can yield benefits for healthy adults and those beginning to lose their mental edge.
The best bets to maintain brain health are to eat a plant-based diet rich in berries, red grapes and curried food, drink green tea, regularly exercise, take time to relax, and keep learning. Should herbs be taken to ward off dementia? Research hasn’t completely answered that question. In the meantime, Dr. Jerry Cott is taking his daily dose of bacopa and ginkgo.
