Omega-3s May Improve Cognitive Function Later in Life

People with mild cognitive impairment have an increased risk of developing dementia. A recent study suggests that taking an omega-3 supplement may help improve cognitive functioning, including memory and perceptual speed, in mature adults with mild cognitive impairment.


Participants in the study included 86 people with mild cognitive impairment and a mean age of 71. They were given either an omega-3 supplement containing 720 mg of EPA and 480 mg of DHA or a placebo daily for six months.


At the conclusion of the study, the researchers noted significant improvements in perceptual speed, space imagery efficiency, and working memory in the omega-3 group. No improvements were noted for mental arithmetic efficiency or recognition memory.


The results varied by gender, with men showing more improvements in perceptual speed, space imagery efficiency, working memory, and total BCAT scores, while women showed improvements in perceptual speed, space imagery efficiency, and total BCAT scores.


Researchers from Zhengzhou University, The Center for Disease Control and Prevention of China, and the Tianjin Institute of Health and Environment Medicine conducted the study. It was published on January 10, 2017, in the journal Nutrients.


Omega-3s have been linked to a number of health benefits, including improved mood, improved joint mobility, reducing the risk of age related macular degeneration, and aiding your immune system.


Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For people who don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.
