Alzheimer’s disease is a devastating neurologic disorder that affects millions of people worldwide. It is a progressive condition that causes the brain to shrink and brain cells to die.
This leads to dementia, a continuous decline in thinking, behavioral, and social skills that affects a person’s ability to function independently.
Alzheimer’s disease is the most common cause of dementia and is a major public health issue. With the aging of the population, the number of people with Alzheimer’s disease is expected to rise dramatically in the coming years.
The process of Alzheimer’s disease begins years before disease onset. Therefore, searching for prevention strategies is very important.
Researchers have been studying the effects of diet on cognitive function in older adults.
Omega-3 long-chain polyunsaturated fatty acids (LC-PUFA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, are well accepted as being essential components of a healthy, balanced diet.
They are found in fatty fish, such as salmon, as well as in nuts and seeds.
Previous research has found that omega-3 LC-PUFA nutritional supplementation may offer beneficial effects on brain structure and function.
However, experimental evidence in older people without dementia is inconsistent. This may be due to the low sensitivity of tests for detecting subtle improvements in cognition in healthy people.
In a recent study, researchers from Charité-Universitätsmedizin in Germany examined the effect of omega-3 supplementation on learning and memory formation in healthy older people.
The team tested 44 healthy people aged 50-75 years. These people took either LC-n3-FA (2,200 mg/day) or a placebo for 26 weeks.
Before and after the intervention, the team tested the participants’ memory performance using a variety of cognitive tests.
The results showed that people who took omega-3 supplements showed better memory performance than people who took a placebo.
The study provides further evidence that omega-3 supplements can have positive effects on memory functions in healthy older people.
The researchers believe that omega-3 supplements may work by reducing inflammation in the brain, improving blood flow, and enhancing the function of brain cells.
One limitation of the study is that the intervention period is short. Future work needs to see if long-term omega-3 supplementation provides similar benefits to memory function.
In addition, it is important to note that this study only examined healthy older people without dementia. It is not yet clear whether omega-3 supplementation can help prevent or slow the progression of Alzheimer’s disease or other forms of dementia.
Despite these limitations, the study highlights the potential benefits of omega-3 supplements for maintaining cognitive health in older adults.
Omega-3 supplements are widely available and are considered safe when taken at recommended doses. However, it is important to talk to your doctor before starting any new supplements or making changes to your diet.
In conclusion, the study by Nadine Külzow and colleagues provides encouraging evidence that omega-3 supplementation can have positive effects on memory functions in healthy older people.
While more research is needed to fully understand the benefits of omega-3 supplements for cognitive health, this study adds to the growing body of evidence supporting the role of diet in maintaining brain function in aging populations.
As the global population ages, it is becoming increasingly important to find ways to promote healthy aging and prevent cognitive decline.
