Alzheimer's disease is a progressive condition that attacks the brain and robs a patient of his memory and ability to maintain independence. While this disease is still not well understood and there is no cure, there are options that may help slow its progression and manage symptoms. These options include medications, participating in activities that challenge the mind and maintaining good health through diet and regular exercise. In addition, adding foods rich in omega-3 fatty acids may also help. However, the first step is to speak with a physician before starting any new treatment approach.
Identification
Alzheimer's disease accounts for 50 to 70 percent of all dementia cases; however, it is not the only cause of memory loss. With age, the brain cells naturally change and become less efficient. While the exact cause of Alzheimer's is not known, it appears that structures called plaques and tangles are what cause the damage that leads to Alzheimer's, reports the National Institute on Aging. Plaques and tangles are forms of protein that build up inside and between cells in the brain and hinder communication between the cells. As communication slows or stops, the cells begin to die. While the formation of plaques and tangles happens to many individuals with age, those with Alzheimer's tend to have more.
Omega-3 Fatty Acid Deficiency
Omega-3 fatty acids are essential for the body to work properly; however, the body does not make them. According to the University of Maryland Medical Center, omega-3s are found in high concentrations in the brain and appear to play a role in behavior, memory and cognitive ability. A deficiency of omega-3 fatty acids can cause poor memory, mood swings and depression along with other symptoms.
Benefits
While much more research is needed, the Alzheimer's Association recommends adequate intake of omega-3 fatty acids as they may help reduce the risk of dementia and cognitive decline. It is important that the brain has enough of the omega-3 fatty acid called docosahexaneoic acid or DHA, as this fatty acid helps brain cells communicate with one another. However, you should take omega-3 fatty acids in combination with medication and other therapies to fully manage your condition.
Sources
Omega-3 fatty acids are also beneficial in reducing cholesterol levels and in turn, in reducing plaque buildup along the blood vessel walls, including the blood vessels in the brain. Due to this, omega-3 fatty oils should be part of the daily diet for those at risk of memory loss, suggests the Mayo Foundation for Medical Education and Research. While there are no specific omega-3 guidelines for those with Alzheimer's, a general recommendation is to get at least two servings per week of fish, such as mackerel, tuna, salmon, sturgeon, mullet, bluefish, anchovy, sardines, herring, trout, and menhaden, which is baked or broiled and not fried. You can also take fish oil supplements, but dosage should not exceed 3 grams a day. For those who do not consume fish, flax seed is another good source of omega-3s.
Warnings
More than the recommended amount should not be taken unless under a doctor's supervision as high levels of fish oils can inhibit blood from clotting and may hinder immune system function and may raise LDL cholesterol levels. Even staying within the allowed dosage may lead to belching, bad breath, heartburn, nausea, loose stools, rash, and nosebleeds, warns the MedlinePlus. Fish oils can also interact negatively with many medications.
