They contain other phenolic compounds including anthocyanins, flavonols, tannins, ellagitannins and phenolic acids. Their medical uses have proved beneficial for improved vision, lowered blood glucose, anti inflammatory and lowering lipid effects and to promote antioxidant defense and lower oxidative stress. It is used to improve cognitive memory.
ANTHOCYANINS: The term named from Greek words are water soluble vacuolar pigments that are found in cell vacuole, mainly in outer cell layers. They have high medicinal properties and give bilberry the blue black appearance. Anthocyanin helps in critical areas of the brain.
WHAT IS COGNITIVE MEMORY? Cognitive Memory refers to all mental abilities and capabilities in relation to attention, memory, judgment and evaluation, reasoning, decision making, language etc.
Bilberry For Cognitive Health
Bilberry posses a number of medicinal properties that has many health benefits. It is suggested to improve night vision. Special compounds that are present increase the production of brain cells in hippocampus. It boosts cognitive function. Bilberry extracts intake has improved memory in older persons.
BILBERRY EXTRACTS IN COGNITIVE MEMORY
The small sized berries is full of antioxidants that play a major role in protecting the brain. Special compounds that are present increase the production of brain cells in hippocampus. It boosts cognitive function. Bilberry Flavonoids including anthocyanins have the capability to enhance memory and prevent mental illness and improves its functioning. It helps to improve memory and slow age related loss of cognitive functioning. Bilberry functions through anthocyanins and flavonoids work by inhibiting neuroinflammation, activating synaptic signaling and improves the blood flow to brain. Anthocyanins can cross blood brain barrier. Consumption of bilberry has proved that it could limit or cure age dependent deteriorations in memory and cognition.
The antioxidants that are present in the bilberry help to reduce the stress of oxidation in brain. This role helps in fighting against Alzheimer’s disease. The bilberry components protect against damage caused by ROS which are causative factors for Alzheimer’s disease. When studies were conducted in rats it proved that bilberry helps in improving the learning capacity and improve motor skills in the brain. Vitro studies proved that polyphenols found in bilberry can remodel amyloid beta aggregation. Bilberry extracts protects against inflammation induced damage in cells through reduction in inflammatory mediators.
ANIMAL STUDIES OF BILBERRY EXTRACTS COGNITIVE MEMORY
In a study aged rats were administered with dietary supplementation with bilberry for eight weeks. It proved indicators of neuronal function. Bilberry extracts helps in motor functioning and cognitive functioning in aged rats.
HUMAN STUDIES OF BILBERRY IN COGNITIVE MEMORY
Population based epidemiological evidence proved that bilberry intake help against Alzheimer’s and Parkinson’s disease. Bilberry extracts intake has improved memory in older persons.
In a related study, supplementation of bilberry improved cognitive memory performances in many older adults who suffer from mild cognitive impairments which were screened by using functional magnetic resonance imaging. Human studies related to bilberry are very less. Therefore to prove the action of bilberry in cognitive memory is still not accomplished completely.
