Dementia refers to a group of symptoms associated with deterioration of the brain, and is one of the most common problems of aging around the world.

Alzheimer’s is the most common disease of dementia and accounts for up to 80% of cases. The first signs of the disease usually include mild problems with memory, but health experts say the early signs of Alzheimer’s may already appear long before that.

Researchers at the Brain Institute in Paris studied the health records of more than 20,214 people with Alzheimer’s disease in the United Kingdom and 19,458 patients from France.

The researchers compared this data with each person’s 15-year medical records and looked at people who had and who did not get a diagnosis of progressive brain disease.

About 123 health conditions were reported, and of these cases, 10 had a greater association with Alzheimer’s disease.

The study was published in “The Lancet Digital Health,” and the experts who carried out the research said that diseases such as Alzheimer’s can start in the brain two decades before the onset of symptoms.

Here are the 10 signs that can predict your risk of developing Alzheimer’s disease:

– major depression

– worry

– constipation

Abnormal weight loss

Reaction to extreme stress

– Sleep disorders

– hearing loss

A type of arthritis called cervical spondylosis

– the fall

Fatigue

The study’s lead author, Dr. Thomas Nedelek, explained that the study’s findings make it possible to look at risk factors for Alzheimer’s disease and how to prevent them.

“The question remains whether the health problems we face are risk factors, symptoms, or warning signs of disease,” he added.

The team notes that the study had many limitations, including that it was an observational, not a clinical trial, and was not able to take into account other risk factors such as socioeconomic status and genetics.

It’s important to note that not everyone with the 10 symptoms in the study will develop Alzheimer’s disease, said Dr. Claire Sexton, director of science and outreach programs at the Alzheimer’s Association in the US.

Speaking to Medical News Today, Sexton said: “Just because someone is depressed does not mean they will develop Alzheimer’s disease. However, this data supports the idea that caring for one’s mental health is extremely important to overall well-being and potential cognitive health.”

If you think you may have Alzheimer’s disease, it is important to seek help from your GP.

The NHS explains that because Alzheimer’s symptoms develop slowly over time, they can sometimes be difficult to detect.

The guidelines state that there is no single test that can be used to diagnose Alzheimer’s disease.

The agency added that it is important to remember that memory problems do not necessarily mean that you have Alzheimer’s disease.
