Fish oil supplements reduce cognitive decline

16 July 2014

A study conducted by Rhode Island Hospital researchers has found that regular use of fish oil supplements (FOS) is associated with a significant reduction in cognitive decline and brain atrophy in older adults. 

The research, which has been published in the journal Alzheimer's & Dementia, analysed the relationship between FOS use during the Alzheimer's Disease Neuroimaging Initiative (ADNI) and indicators of cognitive decline. 

Principal investigator Lori Daiello, PharmD, of the Alzheimer's disease (AD) and Memory Disorders Center at Rhode Island Hospital, said finding ways to prevent AD or slow cognitive decline in normal aging is "of utmost importance".

In this retrospective study, older adults involved in the ADNI study were assessed with neuropsychological tests and MRI scans every six months. The group included 229 older adults who were cognitively normal; 397 who were diagnosed with mild cognitive impairment; and 193 who had been diagnosed with AD. 

It found that using fish oil supplements was associated with significantly lower rates of cognitive decline as measured by the Alzheimer's Disease Assessment Scale (ADAS-cog), and the Mini Mental State Exam (MMSE). However, this was only experienced in adults who didn't have AD at the time of enrolment.
