DHA Omega-3s May Improve IQ in People with Mild Cognitive Impairment

Mild cognitive impairment occurs in many people as they age, creating issues with memory and other cognitive function. A recent study suggests that supplementation with DHA omega-3s may help improve IQ in people with mild cognitive impairment.


Participants in the study included 240 Chinese adults, age 65 and older, with mild cognitive impairment. Over the course of 12 months they were given either 2 grams per day of DHA omega-3s or a corn oil placebo. The researchers measured cognitive function and hippocampal volume at the beginning of the study, after six months, and at the conclusion.


After 12 months, the researchers noted a 10% improvement on the Full-Scale Intelligence Quotient (IQ) in the DHA omega-3 group, when compared with the placebo. They also noted statistically significant improvements in the Information and Digit Span sub-tests in the DHA group. In addition, there were significant differences in volume of the left hippocampus, right hippocampus and global hippocampus between the two groups.


Researchers from Tianjin Medical University in China conducted the study. It was published on October 1, 2016, in the Journal of Alzheimer’s Disease.


There are two types of omega-3 fatty acids found in fish: DHA and EPA. 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.
