Omega-3 supplements may help prevent dementia and Alzheimer's, study reveals

News Topical, Digital Desk : Medications only alleviate the symptoms of Alzheimer's, not prevent or reverse the disease. This is why researchers are now focusing more on prevention and lifestyle modifications.

In this context, a recent study showed that omega-3 fatty acids, found in fish and fish oil supplements, may be beneficial for brain health and reduce the risk of diseases like Alzheimer's. Let's learn more about this.

What is Aldimer and why is it dangerous?

Alzheimer's disease alone accounts for approximately 60–70% of all dementia cases. It initially begins with mild forgetfulness, such as inability to remember recent events or losing things. It gradually progresses to severe confusion, behavioral changes, and loss of independence.

There are several reasons behind this:

• The accumulation of plaques and tangles in the brain, which prevent neurons from communicating with each other.
• Inflammation and oxidative stress, which lead to the destruction of brain cells.
• Shrinkage of the hippocampus (where memories are stored).
• Age and genes are the biggest factors, but diet and lifestyle also play a big role.

Omega-3 fatty acids are essential for the brain

Our body cannot produce Omega-3 on its own, hence it is necessary to take it from outside.

• Natural sources: Fish like salmon, sardines, mackerel, and anchovies.
• Supplements:  Fish oil capsules , cod liver oil, or algae-based supplements for vegetarians.

Studies show that people with high levels of omega-3 in their blood have a lower risk of memory loss or dementia.

How is fish oil helpful?

Omega-3 fatty acids protect the brain in several ways:

• Reduces brain inflammation, which may slow the progression of Alzheimer's.
• Keeps neurons flexible and active.
• It improves blood circulation and delivers oxygen and nutrients to the brain.
• Prevents damage to the hippocampus, which is the most important part for memory.

What did the clinical trials reveal?

• Although observational studies are encouraging, clinical trials have shown mixed results.
• Taking fish oil has been shown to improve memory and concentration in people with mild memory loss.
• However, in those where Alzheimer's had progressed further, its effect was limited.
• Experts believe that if it is taken in the initial stages, it can be more beneficial.

Is it better to eat fish or take supplements?

DHA and EPA are naturally found in fish, along with  vitamin D , selenium, and protein. Experts recommend eating fatty fish at least twice a week. However, supplements may be the best option for those who don't eat fish.

Not only Omega-3, these things are also important

Supplements alone are not enough to maintain brain health. Your entire lifestyle plays an important role.

• Foods rich in vitamin B12, folate, antioxidants and polyphenols.
• Foods rich in vegetables, fruits, nuts, grains and olive oil.
• Regular physical activity increases blood flow and growth of new cells in the brain.
• Good sleep and stress-reducing habits improve memory.
• Reading, solving puzzles, and learning new skills keeps the mind active.
