Omega-3 supplementation in cognitive decline


In humans, about 90% of all the brain’s neurons are located in the cerebral cortex (the outer layer), which is composed of grey matter. Most of the information processing in the brain takes place in diverse areas of the cerebral cortex (involving memory, attention, perception, thought, language and consciousness). The cerebral cortex is found only in mammals; in larger ones (including humans), its surface folds to create ridges and furrows, which increase its surface area.

Age-related cognitive decline is characterized by a progressive and irreversible loss of grey matter in many brain regions. But, what are the relationships between grey matter volumes, cognitive performances, and omega-3 fatty acids cerebral levels? Many studies have shown neurological and cognitive beneficial effects of omega-3 fatty acids in aging.

According to a recent research, omega-3 fatty acids supplementation in old age could help maintain brain functionality by counteracting reductions in grey matter volume (brain atrophy), cognitive decline, and emotional dysfunctions. Dietary supplementation with omega-3 may be considered as a strategy to counteract aging-related cognitive decline, even when the supplementation starts at late age.




Omega-3 may slow the cognitive decline

When we speak of cognition, we are referring to the combination of mental processes that includes the ability to learn new things, intuition, judgment, language, and remembering. T[...]
