A new study published in the Journal of Neuroscience suggests that an omega-3 fatty acid found in algae may help to reduce a person's risk of late-onset Alzheimer's disease.
Researchers at the University of California, Los Angeles, found that docosahexaenoic acid (DHA) boosts production of a protein called LR11, which is vital for removing enzymes responsible for the production of Alzheimer's plaques from the brain.
Patients with Alzheimer's disease are known to have reduced levels of LR11 protein, but the researchers hope that by boosting intake of DHA it may be possible to interrupt and prevent late-onset dementia.
Dr Edward Nelson, vice president of medical research for US firm Martek, commented: "This study adds to the evidence supporting the important brain health benefits provided by an enhanced DHA status, and there are a number of ongoing studies investigating the role of DHA in reducing the risk for neurological diseases like Alzheimer's."
