ABSTRACT
Omega-3 fatty acids are related to healthy aging all over life. A moment ago, from fish, source omega-3 fatty acids DHA and EPA have been related with fetal development in AD and cognition related problems. Nevertheless, since the human body does not effectively produce few omega-3 fatty acids, while obtaining from marine sources. The brain is extremely augmented with lipids bilayers. Therefore, it is accountable to undertaken that the combination of different fatty acids within brain ha importance for brain functioning, counting neuropsychiatric and cognition development. To know the special effects form fatty acids ingestion, we need to depend on the mutual evaluation of experimental studies, observations, and interventional studies. The brain is enriched with lipid bilayers of omega-3 fatty acid constituents like DHA and EPA may have lots of effects on the brain. The potential function of omega-3 fatty acid, DHA, and EPA in the inhibition of cognition degeneration including AD has involved key importance from the last few decades. Additionally, AD has delivered the utmost positive sign to backing the situation that inflammation gives to a neurodegenerative disorder. The main etiology of the AD is unidentified, but genetic and ecological parameters are supposed, like family history, poor lifestyle and poor diet, the existence of any chronic disease like cardiovascular disease, increased age, and diabetes. It is assumed 174that primarily, management or prevention of inflammation may delay the indications of AD. Normally, changes the brain physiology with increased aging, comprising reduction of elongated chain omega-3 fatty acids as well as the brain of AD patients have reduced the DHA presence. Provided supplementary DHA can decrease the indications of inflammations. The health-related benefits of omega-3 fatty acids are really appreciable. Presently, there is no evidence of maintenance or confirmation of that modifiable risk parameters like herbal medicines, nutritional supplements, modified diet, etc. are associated with reduced the risk factors of AD or the cognition failure. Even though, multiple studies are showing that lifestyle and diet-related parameters are the main risk factors for AD and cognition behavior. This chapter basically focused on the different functions of omega-3 fatty acids mainly DHA and EPA in different neurodegenerative diseases and disorders.
