Improves Mild Cognitive Impairment
The researchers measured cognitive function, including a full-scale intelligence quotient (IQ) test and two IQ subtests which serve as indicators of both short and long-term memory. The tests were administered after six months and again after 12 months. The DHA group showed a 10 percent higher IQ than the placebo group. There were also significant increases in both IQ subtests and brain hippocampus volume in the DHA group. Decreased hippocampus volume is a primary indicator of Alzheimer’s disease.
