DHA in persons with mild cognitive impairment


The hippocampus is a small region of the brain that forms an important part of the limbic system, the area that regulates emotions, and is involved in the storage of long-term memory (all past knowledge and experiences), spatial orientation, and spatial memory. Damage to the hippocampus can lead to loss of memory and difficulty in establishing new memories, and there is a correlation between hippocampal atrophy (the reduction of its volume) and the degree of cognitive impairment.

Some cognitive decline is a normal part of aging, but people with mild cognitive impairment have more memory problems than other people their age, although these problems are not severe enough to interfere with daily life. Persons with mild cognitive impairment have a higher risk of developing Alzheimer’s or another type of dementia. In Alzheimer’s disease, the hippocampus is one of the first regions of the brain to be affected, and this leads to the memory loss and disorientation commonly seen in the early stages of the process.

According to a recent study DHA supplementation may improve cognitive function and slow the progression of hippocampal atrophy in persons with mild cognitive impairment.
