Smartwatch could help detect Parkinson’s disease 7 years before symptoms appear

A new study finds smartwatches may be able to identify Parkinson’s disease up to seven years before characteristic symptoms appear and a clinical diagnosis can be made.

Researchers at Cardiff University in the UK have shown that combining just one week’s worth of data from a smartwatch with artificial intelligence (AI) can help identify people who develop Parkinson’s disease about seven years later.

The researchers say it could be used as a new screening tool for Parkinson’s disease and could detect it much earlier than current methods.

“Smartwatch data is easily accessible and low cost. This kind of data could be used to identify individuals with very early stages of Parkinson’s disease in the general population,” said the UK. said Cynthia Sander, Ph.D., of Dementia Research. Institute of Cardiff University.

“We have shown here that one week of data can be used to predict events up to seven years ahead. These results can be used to develop a valuable screening tool for early detection of Parkinson’s disease. It’s possible,” she added.

Parkinson’s disease affects cells in the brain called dopaminergic neurons, located in an area of ​​the brain known as the substantia nigra. It causes motor symptoms such as tremors, stiffness, and slowness of movement.

By the time these characteristic symptoms of Parkinson’s disease begin to appear and a clinical diagnosis is made, more than half of the cells in the substantia nigra have already died.

Therefore, researchers said they needed cheap, reliable, and easily accessible methods to detect early changes so that they could intervene before the disease does more damage to the brain.

They analyzed data collected from 103,712 UK participants who wore a medical-grade smartwatch for seven days between 2013 and 2016.

The device continuously measured the average acceleration, or speed of movement, over a period of one week.

They compared data from a subset of participants already diagnosed with Parkinson’s disease with data from a separate group who had a diagnosis up to seven years after the smartwatch data was collected. .

However, a limitation of this study is that it cannot be replicated using different data sources, as no other comparable datasets exist at this time to allow similar analyses. But Sander said extensive evaluations were conducted to mitigate bias.
