It is unknown how much of cognitive decline is intrinsic to aging or caused by disorders like Alzheimer's, but it can be brought on by changes that take place in our brain cells.
Scientists examined the impact of giving a group of people a type of vitamin B3 in order to enhance energy metabolism in the brain.
The scientists discovered that nicotinamide riboside, a dietary supplement, was changed into a chemical involved in energy consumption in neurons.
Following supplementation, they also noticed a slight but significant drop in the amounts of amyloid beta protein in neurons.
Aging is more than simply a number, and aging processes have an impact on our cells. Several studies have recently concentrated on the cause of why some people age more quickly than others.
Dementia is one condition for which being older is a risk factor. An estimated one-third of those over 85 have dementia of some kind. Reliable Source.
The World Health OrganizationTrusted Source says that there are already more than 55 million individuals living with dementia globally, and that there are about 10 million new cases every year as a result of people living longer.
The causes and risk factors underlying dementia are poorly understood, despite its great incidence.
The general consensus is that Alzheimer's illness.
But first, he explained, "we wanted to understand whether we could detect a rise in NAD+ in brain tissue after taking the supplement." "This is something we are actively exploring currently in my laboratory in a follow-up experiment in older persons with mild cognitive impairment," he said.
"We accomplished this utilizing tiny vesicles from the blood that we are fairly certain came from neurons. The fact that we also saw alterations in more well-established markers of Alzheimer's disease (such amyloid beta) following supplementation is particularly intriguing, he continued.
