Well, according to a new study published in a journal called Alzheimer's and Dementia, it might!
The study, which took place in Rhode Island, tested 819 people who had MRIs and psychological tests done every six months. Out of the 819 participants, 229 had no cognitive impairment, 397 participants had some cognitive impairment, and 193 participants where diagnosed with Alzheimer's Disease.
After participants were given the Fish Oil and studied for some time, researchers found that the 229 participants that had no cognitive impairment had "increased brain preservation." The participants with mild cognitive impairment and Alzheimer's Disease showed some reduced brain atrophy. The Fish Oil also showed to maintain brain activity in individuals with cognitive impairment.
So, is it worth adding Fish Oil supplements to our dementia loved one's vitamin and medication pill boxes? It wouldn't hurt! Of course, clear it with their doctor first.
