Most people are less concerned about growing old than they are losing their independence. Nothing undermines that independence more than loss of memory. According to a study from EpidStat Institute in Evergreen, Colorado, there is much people can do to protect their brains, starting with the omega-3 fat DHA. In this meta-analysis of studies on omega-3s and memory outcomes in healthy adults aged 18-years and older with or without mild memory complaints, the researchers found that episodic memory was improved with supplements of the omega-3 fats DHA and EPA. Regardless of mental status at the start of the study, more than 1 gram of DHA and EPA improved episodic memory. Semantic and working memory were improved with DHA. The researchers conclude that DHA, alone or with EPA, improves memory function in older adults with mild memory complaints.
In Perspective: Episodic memory relates to how well personal experiences are recalled, while semantic memory reflects past events that are not personal. Working memory is how well a person can process and synthesize new and previously learned information.
