Date Time Parkinson’s disease: wearable sensors to track symptoms EPFL scientists have developed algorithms that, combined with wearable sensors, could help clinicians to monitor the progression of Parkinson’s disease and assess the effects of medications commonly used by people with this neurodegenerative disorder. Parkinson’s disease affects neurons in an area of the brain that controls movement, causing tremors, difficulty walking and other motor problems. Doctors caring for people with Parkinson’s disease need to be able to assess the severity of the symptoms and alter the doses of medications that reduce such symptoms. To do so, clinicians rely on a handful of tests, such as those that measure gait speed – or how fast people walk. However, these tests are typically conducted in the clinic once every few months, and results can be affected by several factors including the experience of the person conducting the assessment. ....
Under a cross-disciplinary program spearheaded by EPFL, scientists will develop an AI-based system that can predict whether Covid-19 patients will develop severe cardiovascular complications and, in the longer term, detect the likely onset of inflammatory disease. Covid-19 comes with a range of symptoms – from a sore throat and the loss of taste to more serious ones like lung failure. But how can doctors predict how serious the disease will be when it first manifests? “The interaction between the viral infection, the host’s response, and the development of cardiovascular inflammation and injury is still poorly understood. It’s hard to know whether a patient’s symptoms will remain mild or rapidly deteriorate and trigger multiple organ failure,” says Adrian Ionescu, a professor at EPFL’s Nanoelectronic Devices Laboratory, within the School of Engineering. If doctors could use a scientific method to better understand and predict the likelihood of a patient’s condi ....
