AI Algorithm Predicts Cognitive Decline

If you have ever wondered what the future holds in terms of how aging will affect your mental abilities, a team of researchers from McGill University and the University of Toronto may have some answers that will help predict cognitive decline.

According to a new study, published in PLOS Computational Biology, using data from the Alzheimer’s Neuroimaging Initiative, an AI (Artificial Intelligence) algorithm that learns signatures gathered from clinical data, genetics and magnetic resonance imaging (MRI) can help predict cognitive decline expected in the next five years.  Because there has yet to be a cure for Alzheimer’s Disease (AD), early detection and prevention measures such as lifestyle changes could delay or possibly even prevent the onset of Alzheimer’s.  

Researchers studied more than 800 healthy seniors, those with mild cognitive impairments and participants that had a diagnosis of Alzheimer’s disease.  It is hoped that with further refinements, the testing could predict dementia even sooner, allowing for better prevention interventions and improved patient care.

According to the World Health Organization, nearly 50 million people worldwide have dementia and with a rapidly aging population, that number is expected to reach 152 million by 2050.  Alzheimer’s disease accounts for roughly 60 to 70 percent of all cases of dementia but research has failed to find an effective treatment.  

The burden Alzheimer’s places on health care systems and family caregivers is becoming increasingly heavy. In America, Alzheimer’s is the most expensive disease, costing more than cancer and heart disease.  According to the Alzheimer’s Association, in 2018, the cost of caring for those with AD will total an estimated $277 billion.  As the number of older adults living with Alzheimer’s increases, so too will the costs.   Research has found that about 35 percent of cases of AD could be prevented with lifestyle changes including stopping smoking, preventing hearing loss and getting regular exercise to maintain a healthy weight and normal blood pressure.   Learn more about AD prevention by following this link to Fisher Center for Alzheimer’s Research Foundation.
