Alzheimer's disease (AD) is a progressive, neuro-degenerative disease characterized in the brain by abnormal clumps and tangled bundles of fibers composed of misplaced proteins. Age is the most important risk factor for AD; the number of people with the disease doubles every 5 years beyond age 65. Symptoms of AD include memory loss, language deterioration, impaired ability to mentally manipulate visual information, poor judgment, confusion, restlessness, and mood swings. Eventually AD destroys cognition, personality, and the ability to function. The early symptoms of AD, which include forgetfulness and loss of concentration, are often missed because they resemble natural signs of aging.

Alzheimer's disease itself cannot be prevented, but there are steps people can take in order to reduce memory loss and dementia when it comes to the development of the disease. Also, some scientists speculate that even though it cannot be completely prevented, there are some things people can do in order to reduce their risk of developing the disease. There are many different medications and vitamin supplements that can be used to relieve and manage some of the symptoms of AD. Also, other medications may help control behavioral symptoms such as sleeplessness, agitation, wandering, anxiety, and depression. AD is a progressive disease, but its course can vary from 5 to 20 years. The most common cause of death in AD patients is infection.

Research has shown that vitamins C and E do help to reduce the risk of memory impairment as people age by about 30 percent. The vitamins have also been shown to reduce the chance of developing the disease by approximately 70 percent. A study published in the Archives of Neurology showed that people who ate Omega 3 rich fish such as salmon once a week or more had a substantially lower risk of Alzheimer's disease. In fact, the seven-year study of 815 nursing home residents found those who reported eating fish at least once a week had a 60 percent lower risk of Alzheimer's compared to those who rarely or never ate fish. If the mercury content in the fish you are eating is a concern or if you are just not eating enough Omega 3 rich fish, you may want to consider adding Omega 3 fatty acids to your diet. When taking vitamins it is important to consult your doctor, as vitamins can carry risks, too.

Another study suggests that high homocysteine levels are linked with mental declines associated with Alzheimer's disease in elderly people. High levels of a substance in the blood called homocysteine tops the list of potentially new risk factors for heart disease, stroke, and now dementia. Elevated levels of homocysteine is an indication of inadequate folate and vitamin B-12 in the diet. High homocysteine levels can be treated very easily with vitamins, including folate, niacin, and B-12. Though nutritional deficiencies can be the cause, some medications like the seizure drug Dilantin can elevate homocysteine levels in the blood. Kidney disease, alcohol use, and too little physical activity can also elevate homocysteine.

Not everyone with Alzheimer's Disease has the same symptoms. You can use the information on the vitamins listed in the above paragraphs to discuss with your doctor. He or she will be able to help you determin what is best for you. Remember not to add to your medications or stop taking any without first consulting your physician. Certain vitamins, minerals and herbal supplements can react adversely with medications you may already be taking.
