Latest studies revealed that adding oily fish such as salmon and trout or fish oil supplements in one’s diet can significantly improve memory in older adults.
The reason is the DHA found in fish oil supplements could be key in preventing Alzheimer’s disease, one of the most common forms of dementia.
During the US Alzheimer's Disease Neuroimaging Initiative (ADNI) and indicators of cognitive decline, researchers at Rhode Island Hospital examined the relationship between fish oil supplements
Studies regard the alter brain function advice that older adults should assessed with neuropsychological tests and brain magnetic resonance imaging (MRI) every six months and in such a study, which included 229 older adults who were cognitively normal; 397 who were diagnosed with mild cognitive impairment; and 193 with Alzheimer's disease (AD), taken as experiment, shows that fish oil supplement use was associated with significantly lower rates of cognitive decline and brain atrophy in older adults.
The principal investigator Lori Daiello from Rhode Island Hospital said, "Participants with normal cognition who reported taking fish oil supplements demonstrated less brain shrinkage in key neurological areas, compared to those who did not use the supplements."
