Omega-3 fatty acids related to cognitive status in older adults

Some cognitive abilities decline with aging. The most constant change is cognitive slowing, but other changes also occur: in the attention to various things at the same time (driving, for example), in the working memory (the ability to remember and use relevant information while in the middle of an activity), in the ability to recall new information, in the ability to understand spatial relationships (not knowing how much to turn […]


Preventing cognitive impairment

Omega-3 polyunsaturated fatty acids (group to which EPA and DHA belong) have anti-inflammatory effects and neuronal protective functions, and may be beneficial in the prevention of dementia. Dementia occurs when cells of the brain are damaged by some health condition, and it is characterized by the impairment of cognitive abilities such as attention, memory, language, logical reasoning, and problem-solving, as well as by the ocurrence of changes in mood or […]


DHA in persons with mild cognitive impairment

The hippocampus is a small region of the brain that forms an important part of the limbic system, the area that regulates emotions, and is involved in the storage of long-term memory (all past knowledge and experiences), spatial orientation, and spatial memory. Damage to the hippocampus can lead to loss of memory and difficulty in establishing new memories, and there is a correlation between hippocampal atrophy (the reduction of its […]


Long chain omega-3 slow cognitive decline

Consumption of seafood (rich in long-chain omega-3 fatty acids) has been associated with slower decline in semantic memory (which refers to words and other verbal symbols, concepts, facts or beliefs; their meaning and the relations among them) and perceptual speed (the readiness to attend accurately to some details in perception; i.e., the ability to quickly compare visual patterns or symbols). Moderate to high long-chain omega-3 fatty acid intake has been […]


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, […]


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. The impairment of cognitive health have important consequences for a person’s well-being, because persons who experience it may be unable to care for themselves. Cognitive impairment may occur at any age, but its probability increases exponentially with advancing age. It is known that […]
