Beacon Biosignals Inc. can rest easy now that it has received U.S. FDA authorization of its predetermined change control plan for the Dreem 3s, a wearable sleep monitor that conducts electroencephalograms as users sleep. The authorization allows Beacon to incorporate updates to the Dreem 3S sleep-staging algorithm acquired through machine learning without submitting a new 510(k) application.
Diagnosing depression and other mental illnesses is largely subjective, but that could soon change as Sydney-based Trivarx Ltd. developed an AI-based algorithm that uses heart rate and heart rate variability coupled with sleep disturbance to diagnose major depressive episodes.
Separate teams of investigators have reported new insights into how the brain disposes of metabolic waste via the glia-based lymphatic system, or glymph system. In two papers published in Nature on Feb. 28, 2024, scientists from Washington University in St. Louis described how in sleeping animals, the synchronized activity of neurons drove ionic gradients that facilitated the movement of fluid through brain tissue. And researchers from the Massachusetts Institute of Technology showed that, in a mouse model of Alzheimer’s disease (AD), the glymphatic system mediated clearance of amyloid-β after sensory stimulation at a 40-Hertz rhythm.
Elemind Technologies Inc. may not (yet) be telepathic, but the new company certainly read the mood of investors well as it secured $12 million in seed funding before emerging from stealth this week. While the product has yet to be fully revealed, the company is developing a wearable neurotechnology platform that uses artificial intelligence to read and guide brainwaves using tailored sound stimulation.
A partnership between Gate Neurosciences Inc. and Beacon Biosignals Inc. promises to advance the field of precision psychiatry by using electroencephalogram (EEG) biomarkers to diagnose depression and rapidly assess response to medications. The collaboration will first use Beacon’s U.S. FDA-cleared Dreem 3S headband device and neurobiomarker platform to conduct EEGs in participants in Gate’s phase II trial of zelquistinel, a small-molecule NMDA receptor modulator under development as an antidepressant.
Onera Technologies BV raised €30 million (US$32.7 million) in a series C funding round that will allow the company to accelerate the manufacturing and deployment of its patch-based sleep test system. The funds will also go towards concluding the development of the company’s second-generation polysomnography (PSG) system.
Three former employees of Bose Corp. are banking on their audio experience and Ozlo Sleepbuds helping the millions of people who struggle to sleep soundly each night. That prospect is music to the ears of investors Lifearc Ventures and Artis Ventures, who led Ozlo Sleep Inc.’s $10 million round to bring the wireless, in-ear headphones to market in the next few weeks.
In good news for those who toss and turn in the night with restless legs syndrome and their bed partners, bioelectronic technology appears to reduce the disruptive and uncontrolled movement. Researchers claimed that the NTX100 tonic motor activation (TOMAC) therapy, developed by Noctrix Health Inc., has the potential to transform treatment for people with restless legs syndrome (RLS) who are resistant to medications.
The discovery of increased levels of dopamine in the basolateral amygdala of the brain at the transition from non-rapid eye movement (NREM) to REM sleep in mice suggests a druggable sleep disorder target, according to a Japanese study.
After 25 years of research. Allschwil, Switzerland’s Idorsia Ltd. has had its first drug approved by the FDA – Quviviq (daridorexant) for adults with insomnia. The okay for Quviviq is the result of painstaking research led by the firm’s chief scientific officer, Martine Clozel, whose husband Jean-Paul Clozel is CEO.
