qMRI for early detection of Parkinson’s disease
Aviv Mezer and Hebrew University colleagues used quantitative MRI to identify cellular changes in Parkinson’s disease. Their method enabled them to look at microstructures in the striatum, which is known to deteriorate during disease progression. Using a novel algorithm developed by Elior Drori, biological changes in the striatum were revealed, and associated with early stage…

Neural Network assesses sleep patterns for passive Parkinson’s diagnosis
MIT’s Dina Katabi has developed a non-contact, neural network-based system to detect Parkinson’s disease while a person is sleeping. By assessing nocturnal breathing patterns, the series of algorithms detects, and tracks the progression of, the disease — every night, at home. A device in the bedroom emits radio signals, analyzes their reflections off the surrounding…

Wearable haptic feedback/stimulation band to address Parkinson’s symptoms
Microsoft has submitted a patent application for a wearable band that uses haptic feedback for stimulation when wrapped around limbs or joints. It is meant to alleviate Parkinson’s symptoms, including tremors and muscle stiffness. Haptic actuators are distributed across a band that is adjusted to a “duty cycle” which responds to data derived from wearable…

Focused ultrasound thalamotomy in Parkinson’s Disease
UVA’s Scott Sperling and Jeff Elias, who already used focused ultrasound to treat essential tremor, have just published the results of a small study showing the efficacy of the technology in Parkinson’s Disease. The sound waves were shown to interrupt brain circuits responsible for the uncontrollable shaking associated with the disease. The researchers claim that their study…

Implanted sensors track dopamine for a year
Helen Schwerdt, Ann Graybiel, Michael Cima, Bob Langer, and MIT colleagues have developed and implantable sensor that can measure dopamine in the brain of rodents for more than one year. They believe that this can inform the treatment and understanding of Parkinson’s and other brain diseases. According to Graybiel, “Despite all that is known about…
