Stress may raise the risk of Alzheimer's Disease

Several factors may increase Alzheimer's risk, including age, family history, and genetic makeup, but a new research suggests that vital exhaustion, a marker of psychological distress, may raise the risk of developing Alzheimer's disease. In this research, it was also discovered that certain health issues, such as cardiovascular disease or diabetes, may also influence the odds of experiencing dementia because they impact the blood vessels.


According to the new research, psychological factors could also affect risk and of these factors, Psychological distress, in particular, may increase the likelihood of developing dementia.

Researchers led by Sabrina Islamoska, a doctoral candidate in the Department of Public Health at the University of Copenhagen, Denmark, set out to investigate the possibility of a link between vital exhaustion and Alzheimer's disease. From their investigation, they described Vital exhaustion as "a mental state of psychological distress" that manifests as irritability, fatigue, and a feeling of demoralization.

In an explanation given by the researchers, vital exhaustion may be a reaction to "unsolvable problems" in one's life, especially when the person has been exposed to stress for a prolonged period. So, they classified vital exhaustion as a sign of psychological distress.

This new research comes as a further clarification on vital exhaustion as previous studies have noted that vital exhaustion may raise the risk of cardiovascular disease, metabolic syndrome, premature death, and obesity, among other conditions.

You can check out Islamoska and her colleagues’ findings which they published in the Journal of Alzheimer's Disease. 

Stress may raise risk by up to 25 percent

From the result, the researchers analyzed data from a survey of almost 7,000 individuals who participated in the Copenhagen City Heart Study between 1991 and 1994. The participants had been 60 years old, on average, at the time. As part of the survey, the participants had been asked questions mainly about vital exhaustion. 
 

Islamoska and her colleagues clinically followed the participants until the end of 2016 examining their hospital records, mortality and prescription registers in search of diagnoses of dementia.

The study revealed a link between vital exhaustion in midlife and the development of Alzheimer's later on and according to the lead author’s report, "For each additional symptom of vital exhaustion, we found that the risk of dementia rose by 2 percent."

"Participants reporting five to nine symptoms had a 25 percent higher risk of dementia than those with no symptoms, while those reporting 10 to 17 symptoms had a 40 percent higher risk of dementia, compared with not having symptoms," Islamoska continues.

In further clarifications, the authors explain that it is unlikely that dementia causes vital exhaustion, rather than the other way around.

"We were particularly concerned whether the symptoms of vital exhaustion would be an early sign of dementia," explains Islamoska. "Yet, we found an association of the same magnitude, even when separating the reporting of vital exhaustion and the dementia diagnoses with up to 20 years."

The researchers point to excessive levels of the stress hormone cortisol and cardiovascular changes as potential culprits regarding the possible mechanisms that may underpin the findings.

"Stress can have severe and harmful consequences, not just for our brain health, but our health in general," says Islamoska.

"Cardiovascular risk factors are well-known, modifiable risk factors for dementia, and in some countries, a stagnation or even a decreasing incidence of dementia has been observed."

Islamoska however concluded by saying "Our study indicates that we can go further in the prevention of dementia by addressing psychological risk factors for dementia,"

I hope you are now informed that Stress may raise the risk of Alzheimer's disease.
