Pycnogenol otherwise known as French maritime pine tree extract has been found to be effective at improving senior citizens memories.
Researchers at the Centre for Neuropsychology at Swinburne University, Melbourne Australia, found that the extract improved both numerical working memory as well as spatial working memory in older adults.
The research conducted by Dr. Con Stough, supports other studies that have shown that antioxidants may have an effect in preserving or enhancing specific mental functions.
The study done on 101 seniors aged 60-85 years old, measured the effects of Pycnogenol on a range of cognitive and other biochemical measures.
The subjects were given a daily dose of 150mg of Pycnogenol for three months and tested every month. The control and Pycnogenol groups were sorted by age, sex, BMI, micronutrient intake and intelligence. The groups were tested for attention, working memory, episodic memory and psycho-motor performance.
Researchers noted that F2-isoprostanes levels were significantly decreased in the group taking Pycnogenol. F2-isoprostanes were shown to be the most reliable index of in vivo oxidant stress when compared against other well known biomarkers. It can be inferred than that the lower levels of F2-isoprostanes are responsible for the improvement in cognitive and other biochemical activity.
