Rebrain’s AI software to optimize brain targeting approved by FDA

The U.S. Food and Drug Administration (FDA) has again cleared Rebrain’s OptimMRI software, this time including a new machine learning model to assist in targeting specific brain regions for lesioning techniques such as MR-guided focused ultrasound and radiosurgery. Lesioning techniques involve the destruction of small areas of abnormal brain…

Bladder problems in patients linked to distinct brain networks on MRI

Parkinson’s disease patients with urinary incontinence (UI) exhibit distinct brain activity networks compared with patients without the bladder symptom, according to a recent study. Urinary incontinence was linked to stronger functional interactions between brain regions implicated in Parkinson’s disease and others linked to brain-bladder control. Findings overall “will provide…

Changes in Brain Architecture Tied To Poor Bimanual Coordination

Small-scale, or microstructural, brain alterations observed on the MRIs of people with Parkinson’s disease were associated with worse bimanual coordination, a type of complex movement, a study found. “[D]istinct changes in microstructure cause an impediment of structures involved in attention, working memory, executive function, motor planning, motor control, and…

Exablate Neuro for Advanced Motor Symptoms Now Offered in Maryland

Exablate Neuro, a non-invasive ultrasound treatment of motor symptoms in advanced Parkinson’s patients, is now available at the University of Maryland Medical Center, part of the school that led a pivotal trial of the technology. Based on trial findings, U.S. Food and Drug Administration (FDA) approval of the Insightec device…

China Approves MR-guided Focused Ultrasound to Treat Tremors

Insightec announced that its incision-free brain “surgery” technology — called Exablate 4000 (Exablate Neuro) — has been approved in China to treat essential tremor and tremors caused by Parkinson’s disease. The market approval from China’s regulatory agency for medicines and medical devices, the National Medical Products Administration, will allow the…
