Hormonal changes and stress are two of the main factors influencing cognitive functions in the elderly population. Cognitive difficulties include memory loss and mild cognitive impairment, two factors frequently related to Alzheimer's disease and dementia. In every culture and with every tradition we can see different remedies for different ailments and diseases, even for memory and retention.
BACOPA MONIERI, BABY'S TEARS
Bacopa monnieri, a creeping herb commonly known as Baby's tears, Centella asiatica or Brahmi (in India) that grows in wetlands and muddy shores, has been popularly used in aquariums. In spite this herb grows mainly in India, Nepal, Sri Lanka, China, Taiwan and Vietnam, it has also been found in Florida, Hawai and other southern states of the USA.
In spite some of the active constituents found on this herb are known to be powerful anti-cancer compounds, as apigenin, Bacopa monnieri has traditionally been known to be able to enhance cognitive performance and be effective against cognitive impairment, some of them providing evidence suggesting that Bacopa improves memory free recall with evidence for enhancement in other cognitive abilities. Some studies even suggest that it may be a potential source of active constituents for the treatment of Alzheimer's disease.
Asparagus racemosus, also known as Shatavara, has been used as an Ayurvedic aphrodisiac herb in Vajikarana Rasayana Ayurvedic medicine to treat sexual dysfunction related problems and also as an aphrodisiac. It has also been used in clinical experiments with rats showing an positive effect enhancing memory and protecting against amnesia
CACAO EFFECTS ON MEMORY
A study performed by Lee Fruson, an undergraduate student at the University of Calgary, shows how other dietary factors, namely the intake of dietary flavonoids, may also affect memory and cognition.
Lee Fruson, Sarah Dalesman and Ken Lukowiak, authors of the study published in the Journal of Experimental Biology, focused on a particular type of flavonoids, the epicatechin (epi), found in cocoa, green tea and red wine, all those ones known to exert already many other beneficial properties in our bodies.
GREEN TEA BOOSTS BRAIN CELL PRODUCTION
A recent scientific study on the use of a combination of green tea extract and l-Theanine, demonstrated the beneficial effects that such a cocktail had on the improvement of cognition.
In the study, where a double-blind placebo control was used, patients affected by mild cognitive impairment (MCI), among which 13 were men and 32 women, the volunteers performed different neuropsicological tests and their electroencephalography analyzed. The results showed that an increase on memory and selective attention on those receiving the green tea extract and l-Theanine cocktail, showing the potential use and benefits of green tea extract and l-Theanine for the treatment of cognitive impairment patients.
