Special brain traits may protect “extended” from dementia

These elderly have a moment.

life expectancy In the United States, around 78.4 years – there is a special group of people who exceed this sign of flying colors. Retired, known as the name “Superists,” Show memory and cognitive abilities of middle -aged people.

A new report outside the Northwestern University reveals unique features of Supergrage’s brains that appear Protect them from dementia.

“The results we have reached show that the exceptional memory of old age is not only possible, but it is linked to a distinct biological file.” Dr. Sandra WinteropThe author opposite a new paper summarizes the results.

“This opens the door to new interventions aimed at maintaining the health of the brain well in subsequent decades of life.”

Northwestern’s Supergeer has started more than 25 years ago. To qualifyIndividuals should be more than 80 years, in good health and activity in life.

Excellent are generally very social with meaningful relationships.

About 290 registered since 2000 has been studied. From this group, 79 Western scientists have allowed the autopsy after death.

The researchers reported that the supergraber brains do not tend to not own it Agelueoids and Tow ChapluesTwo distinctive features of Alzheimer’s disease, or if they have, they are not at a level that will cause memory problems.

A professor of psychiatry and neuroscience at Northwestern Medicine at Fennberg College of Medicine at Northwestern Medicine at Fennberg College of Medicine at Fennberg College of Medicine, “What we realized is that there are two mechanisms that lead someone to become super.”

“One of them is resistance: they do not make paintings and tangles.” “Two of flexibility: they make it, but they do nothing for their brains.”

The involved did not appear a great thinning in the cerebral cortex, the outer layer of the brain. They even had a thicker front chick than younger adults.

Cortex is responsible for emotional organization and cognitive functions such as attention, error detection and decision -making.

The supernatural also outperforms more VON Economic cells (specialized cells associated with rapid and intuitive social provisions), the largest entorhinal cells (necessary for memory) and small glial cells (immune cells) compared to their peers.

These may be the brain’s features that are the reason that consistent people who have registered at least nine out of at least in a test requirement of calling the list of words after some time.

These conclusions will be published in Alzheimer’s and Death: Alzheimer’s Association Magazine.

While Northern Northern scientists have learned a lot about Supergrage’s brains, a final answer on how Alzheimer’s is still e -tie.

“I wish I had the answer, I hope to be unemployed,” a co -author of research Tamar sideAssociate Professor of Psychiatry and Behavioral Sciences in Finnberg told The Post.

“Some possibilities: genetics (genetics and alternative – means that genes interact with each other within one person), personal immunity, of course, random events (thought: biological, psychological, environmental stress) that occurs in age,” added Jeffen, director of Venberg for nerve speech.

She pointed to the identification of a Lancet committee 14 Amended dangerous factors.

Researchers suggest treating these behaviors to reduce the risk of dementia – low levels of education, painful brain infection, physical blood, smoking, excessive alcohol consumption, diabetes, obesity, high blood pressure, depression, hearing loss, social isolation, air pollution, and ldl high cholesterol and uncarded vision loss.

Alzheimer’s is the most common form of dementia, but it is not the only type.
