A group of scientists conducted a study to find the connection between fish oil and dementia, and the results showed that regular consumption of fish oil significantly reduces cognitive impairment and brain atrophy in the elderly.
The research involved 229 respondents with normal cognitive abilities, 397 respondents with slight damage to cognitive functions, and 193 people diagnosed with Alzheimer’s disease.
Every six months the respondents went through a series of neuropsychological testing and MRI of the brain.
After the scientists studied the results, they found that respondents who showed no signs of dementia and regularly fish oil include in their diet had no decrease in their cognitive functions.
However, the same group of respondents who do not consume fish oil showed a mild brain atrophy.
Scientists suggest that only positive results were observed in respondents who do not carry the APOE-4 gene, well known for its ability to develop Alzheimer’s disease.
This shows that additional research is more than necessary, but for now the fish oil shows encouraging results when it comes to slow the development of the disease.
