OPAL News from 2006

A review of all available scientific literature has just been completed regarding the use of fish
oil for the prevention of cognitive decline.
The review
published by the
Cochrane Library
in January 2006 concluded that there were currently no published
clinical trials that "could confirm or refute the utility of omega 3 PUFA
[fish oils] in preventing cognitive impairment or dementia".
The review goes on to say that this "is an important area that is in pressing need
of further research".
The conclusion of the review (of which
Alan Dangour
is a co-author) emphasises:
the importance of the OPAL study
to determine the potential for the use of fish oil to slow or prevent
cognitive decline in older people.
