Alzheimer’s is one of those diseases that can kill you in a very slow and painful way. The most common form of dementia induces mental pain rather than physical, which is arguably worse. Alzheimer’s is one of the leading causes of death in the world.

SciTechDaily.com writes about a new study led by Aleix Sala-Vila, PhD, that grants a lot of hope that fewer people will have to deal with Alzheimer’s at some point in life – those having higher blood DHA levels have almost half fewer chances of dealing with the most common form of dementia.

49% fewer chances to develop Alzheimer’s if your blood DHA level is high

DHA refers to docosahexaenoic acid, meaning an omega-3 fatty acid that serves as a crucial component of our brains, skin, as well as retina.

According to the study that involved 1490 participants, there are chances that if a person takes extra dietary omega-3 DHA, especially if he or she has the ApoE4 gene, the development of Alzheimer’s might be slowed down. 

Scientists who did the new research focused on the association of incident Alzheimer’s with red blood cell docosahexaenoic acid.

The researchers said as SciTechDaily.com quotes:

Given that estimated health-care payments in 2021 for all patients with AD or other dementias amount to $355 billion in the US (not including caregiving by family members and other unpaid caregivers), any cost-effective strategy for delaying the onset of AD is of utmost public health interest,

Delaying AD by 5 years leads to 2.7 additional years of life, and 4.8 additional AD-free years for an individual who would have acquired AD and is worth over $500,000.

According to the Alzheimer’s Association, 1 in 3 seniors will die with Alzheimer’s or some other form of dementia.

The new study was published in the journal Nutrients.
