Positrigo AG is raising $10 million for production and commercialization of its Neurolf brain positron emission tomography system in the U.S. The system hepls to diagnose Alzheimer’s disease. With drugs such as Leqembi and Kisunla gaining U.S. FDA approval to treat the devastating neurological condition, the company is seeing increasing demand for its system, Neurolf CEO and co-founder Jannis Fischer, told BioWorld.

New research confirmed long-term efficacy and safety of a novel minimally invasive procedure with Insightec Inc.’s Exablate transcanial magnetic resonance-guided focused ultrasound system to alleviate symptoms of severe obsessive-compulsive disorder.

Our immune cells are not just “defenders” against deadly viruses and pathogens but also a great balancer for tissue homeostasis.

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.

In breaking news, Wave Neuroscience LLC received breakthrough device designation from the U.S. FDA for its magnetic electroencephalogram resonance therapy for adjunctive treatment of post-traumatic stress disorder (PTSD), making its technology the first medical device approved to treat the debilitating condition, the company said.

Researchers at the University of Rochester have described a neuroimaging-based biomarker that could identify individuals with early psychosis, and improved their identification when it was added to a standard neurocognitive diagnostic test. In a group of roughly 160 participants in the Human Connectome Early Psychosis Project, individuals who were in the early stages of psychosis had stronger connections from the thalamus (a midbrain sensory processing area) to the cortex, but weaker connections between different cortical areas, than controls.

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.

Fifty years after the term brain-computer interface (BCI) was coined, Neuralink and several other companies are reviving the promise of BCI for health care, as artificial intelligence and novel methods of neural signal detection work hand-in-hand to propel biomedical innovation.

On the heels of U.S. FDA approval for Neurophet Aqua, an updated version of its artificial intelligence (AI)-based magnetic resonance imaging analysis software for the brain, Neurophet Inc. is preparing for an IPO in 2025 and expansion into U.S. and European markets.

Despite government efforts to prop up biopharma and med-tech research toward creating women’s health products, companies must eventually reach out to the private markets to bring their inventions to the next stage of development. Anna Zornosa-Heymann, a women’s health investor, serves as a part-time contractor with the U.S. NIH’s SEED (Small business Education & Entrepreneurial Development) office, where she helps companies move from government to external funding. Government funds are “excellent to pay for research … but those funds don’t allow you to build a first-class team and to develop a sales apparatus,” she told BioWorld.
