Physical balance may not seem related to cognitive function. But researchers from Japan have recently succeeded in developing a new method to predict cognitive problems according to body balance, according to Neuroscience News, citing the journal BMC Geriatrics.
increased risks
Researchers from the University of Tsukuba have revealed a new measure of physical balance that can help identify individuals at risk of developing Alzheimer’s disease (AD).
MCI is a medical condition characterized by subtle changes in cognitive ability. Because individuals with this condition have an increased risk of progression to Alzheimer’s disease, early identification of MCI can guide medical interventions that can prevent worsening of the condition.
vestibular function
It has long been understood that balance problems occur in individuals with Alzheimer’s disease who have a high frequency of falls, and are due to changes in vestibular function, which is responsible for balance and a sense of spatial direction.
Additionally, it could be to screen individuals for MCI before symptoms appear by finding out if they have problems with physical balance. Currently, there are few options for effective homeostasis screening in the general population, which is the problem researchers at the University of Tsukuba aim to address.
Early interventions for prevention
“Early interventions are essential to prevent Alzheimer’s disease,” says the study’s lead investigator, Professor Naoya Yahagi. “Because changes in vestibular function are associated with both MCI and Alzheimer’s disease, the study aimed to develop a novel method to efficiently assess these changes in the general population.”
A new method of evaluation
The researchers then set out to devise a new method for assessing balance and vestibular function using the Nintendo Wii foam rubber balance board.
The measure was called the Visual Dependency Index of Stability (VPS). Healthy volunteer participants, ages 56-75, without significant cognitive impairment, successfully completed tests of the VPS index as well as measures of cognitive function.
Surprising results
“The results were surprising,” explains Professor Yahagi. “It was found that scores on the VPS were significantly associated with cognitive impairment, which was assessed using the Montreal Cognitive Assessment Index, a commonly used tool for examining cognitive ability.”
Furthermore, the scale had relatively high sensitivity and specificity, indicating that it was successful in readily capturing important clues to indicate whether an individual is at risk of developing Alzheimer’s disease.
New treatment options
Professor Yahagi says the new method could be an inexpensive and accessible way to screen for cognitive impairment in the general population. And therefore
Early and accurate detection of MCI can lead to new treatment options that can significantly improve outcomes for individuals with neurodegenerative conditions.
