Researchers in Chicago have created a "name game" that may be able to be used as an early diagnostic tool for Alzheimer’s disease.

A research team tested 100 seniors between the ages of 65 and 85 who did not have any signs of memory loss. According to the Chicago Tribune, study participants were divided into groups, depending on whether or not they had Alzheimer’s risk factors.

They then had their brain activity monitored using a special MRI while names – some famous and some not – were shown to them and they were instructed to a button to indicate whether or not they recognized the person.

Researchers say the brains of the individuals considered at risk for developing the disease worked differently than those without risk factors and that the findings could lead to an early diagnostic test in the future.

Alzheimer’s disease is the most common form of dementia, with an estimated 5.3 million Americans living with the disease.

According to WebMD, symptoms include impaired memory and thinking, disorientation and confusion, changes in personality and behavior as well as loss of normal sleep patterns.

The Alzheimer’s Association says several nutritional supplements are believed to enhance memory and slow the progression of the disease. They include coenzyme-Q10, gingko biloba, coral calcium, huperzine A and omega-3 fatty acids.
