Researchers explain that fish oil capsules do not slow mental or physical decline in patients of Alzheimer’s. The memory boosting supplements did not affect the progression of the disease. Earlier studies have shown that fish oil supplement which is rich in omenga-3 fatty acids DHA and EPA are known to enhance brain function.
Some studies have also recommended they could slow mental decline in Alzheimer’s patients. In the study that include four hundred males and females aged seventy-six and suffering mild to moderate Alzheimer’s. They were arbitrarily allocated to take either 200mg DHA pills or dummy pills everyday for eighteen months.
DHA naturally happens in the brain but it found in abridged amounts in people with Alzheimer’s disease. The test found similar rates of physical and mental decline in both groups using scoring systems and MRI brain scans. The supplement did not slow down the growth of Alzheimer’s in subordinate group of patients having mild symptoms.
According to experts endeavoring to reverse the disease after appearing of symptoms may be belatedly because the underlying course that causes Alzheimer’s starts years, if not decades, before diagnosis. A recent study found that high dose supplements of DHA enhanced memory and learning in nearly five hundred elderly suffering age related cognitive decline, explained Dr Carrie Ruxton from the Health Supplements Information Service.
By observing broader range of clinical test, it seems that DHA could have beneficial effects on cognitive function in people with mild form of Alzheimer’s disease or early cognitive decline. In the latest study, DHA may have been given too late in the disease process to produce benefit added Dr. Ruxton.
Earlier trials had shown omega-3 supplements were related with abridged risk of developing Alzheimer’s but trials on their use in those who already had the disease failed to show any impact, explained Dr Kristine Yaffe, a dementia researcher at University of California at San Francisco.
Omega-3 fatty acids in fish or supplements have been shown to protect against heart disease and are being studied for potential effects on an array of other diseases, including cancer and depression.
