The brain is composed of nearly 60% fat and it is thought that the lipid in the brain helps to insulate neural tracts and to propel information electrically in an efficient manner. The brain can slow down and function less optimally if the lipid is reduced or damaged. To this end, the study of omega 3 fatty acids, an essential fatty acid in the body, has been studied for Alzheimer's patients and continues to be a major area of interest in relationship to the brain.
Omega 3s including DHA and EPA are critical to optimal brain function. They can be found in fish such as salmon, herring, tuna, mackerel, and sardines. They are also found in unsalted nuts. Fish are good sources of DHA because they consume algae in their own diet. Smaller fish that do not swim at deeper levels of the ocean also reduce the risk of mercury levels that might be a risk for humans.
A recent study published in Alzheimer’s and Dementia revealed algal DHA (algal-900) improved memory in healthy older adults. The memory benefit was nearly equal to skills of those one three years younger. Similar cognitive benefits of DHA have been published elsewhere in healthy populations, but some question remains regarding the benefit of such nutrition in those already diagnosed with Alzheimer’s. DHA may have a preventative effect more than a treatment effect.
While most research being done is only preventive for Alzheimer's we at Spring Arbor are glad that something is being done for Alzheimer's patients. We know that it is a terrible disease and hopefully a cure or more preventive medicine can be formed. So if you know a loved one who is suffered contact us today and we'll be happy to help you through the process and do what we can to help.
