Cod Liver/Fish Oil supplements assessed using repeated measures are prospectively and cross-sectionally associated with Cognitive Performance tests in a population based cohort
Dementia is a condition mainly affecting older people. Non-modifiable risk factors include age and genetic factors; however, lifelong,
modifiable -and largely behavioural- risk factors may be associated with cognitive function and dementia risk (1). Changes in these risk factors
may occur during a person’s life course. There has been much interest in fish consumption in relation to dementia(2) as well as cardiovascular
disease risk(3), suggesting a potential biological pathway for omega-3 polyunsaturated fatty acids (n-3 PUFA). Fish intake has been below
SACN recommendations in the UK(4); whereas cod liver oil (CLO) is the most popular supplement consumed and contributes 50 % to over-
