Can you smell Alzheimer’s? The smelly factor doubles the risk of cognitive decline.


Can you smell Alzheimer’s? The smelly factor doubles the risk of cognitive decline.

ALZHEIMER’S DISEASE is a progressive neurological disease characterized by a loss of mental acuity.

Progressive memory loss and difficulty with language are common symptoms.

According to some studies, one’s sense of smell may provide early warning signs of impending decline.

Dementia affects an estimated 55 million people worldwide, with only a quarter of them receiving a formal diagnosis.

The disease, which has a gradual onset of symptoms, has been extensively researched, but no cure has yet been discovered.

Scientists, on the other hand, have made significant progress in identifying the disease’s early warning signs.

Early clues may emerge in the nose, according to one line of research.

A growing body of evidence suggests that a poor sense of smell is linked to memory loss later in life.

The study’s origins can be traced back to a 2016 study published in the Annals of Neurology, which found that people who struggled to identify scents like menthol, strawberry, and lemon were more likely to develop Alzheimer’s disease.

“When someone can’t distinguish between different smells, it could absolutely be a signal that Alzheimer’s disease is brewing,” said Doctor Isaacson, director of the Alzheimer’s Prevention Clinic at New York Presbyterian Weill Cornell Medical Center.

Researchers followed a group of 3,000 older people with normal cognition in another study published in the American Geriatrics Society.

If four risk factors aren’t addressed, dementia cases are expected to nearly triple by 2050.

A simple smell test was administered to all participants in order to identify those with a higher risk of dementia.

Participants who couldn’t identify four out of five smells were twice as likely to develop dementia five years later, according to the researchers.

Furthermore, the severity of the olfactory deficit was related to the severity of the dementia.

The findings revealed that 4.1 percent of participants developed dementia within five years, with 47 percent having olfactory dysfunction at the time of the initial assessment.

“These findings show that the sense of smell is closely linked to brain function and health,” said Professor Pinto, an ear, nose, and throat specialist.

He went on to say that a loss of smell could be a sign of “serious damage.”

The test could be used to quickly identify people who are at risk of contracting the disease.

In addition to Alzheimer’s disease, a poor sense of smell is linked to an increased risk of death and Parkinson’s disease.
