Washington, July 16 : A new study has revealed that regular use of fish oil supplements (FOS) reduces incidence of cognitive decline and it may improve memory.

The study examined the relationship between FOS use during the Alzheimer's Disease Neuroimaging Initiative (ADNI) and indicators of cognitive decline.

Lori Daiello, principal investigator, PharmD, of the Alzheimer's Disease and Memory Disorders Center at Rhode Island Hospital said that at least one person was diagnosed every minute with Alzheimer's disease (AD) and despite best efforts they have not yet found a cure for this pervasive and debilitating disease.

He further added that they are now researching ways to prevent AD or slow cognitive decline in normal aging, howerver, the positive findings on cognitive testing and brain MRI were only observed in persons who did not carry the best-studied genetic risk factor for AD, APOE-4 so more research would be needed.

It was estimated that more than 5 million people in the U. S. have Alzheimer's disease, which was most common form of dementia and was the sixth leading cause of death in the U. S.

The study is published online in advance of print in the journal Alzheimer's and Dementia. (ANI)
