Researchers have developed an AI-based wearable device, called Revoice, to help individuals communicate effectively after a stroke. The system, worn around the neck, uses sensors to capture carotid pulse signals and subtle vibrations from throat muscles to reconstruct intended words and sentences in real time, potentially transforming the lives of stroke patients living with dysarthria.

A team of international researchers is investigating whether a finger-prick blood test could be used to help diagnose Alzheimer’s disease before symptoms appear. With current diagnostic methods relying on expensive brain scans and invasive lumbar punctures, the trial is exploring whether the simple test could offer a faster, cheaper, and more accessible route to identifying the disease.

The good news is that the U.S. Congress is on track to pass a slate of fiscal 2026 spending bills before the current continuing resolution expires Jan. 30. So, barring any last-minute disputes or legislative hostage-taking, there should be no repeat of last year’s 43-day shutdown that impacted NIH grants and activities.

As the momentum and interest in brain-computer interface (BCI) technologies continue to accelerate, Merge Labs has emerged with an investment from OpenAI in its seed round. Merge Labs says it plans to develop next-generation BCIs capable of interacting with the brain at high bandwidth, integrating with advanced AI, and doing so in ways that are safe and accessible to everyone.

Perhaps the biggest indicator of U.S. President Donald Trump’s activism in his second term is the 225 executive orders (EOs) he issued in 2025. The pace of those orders seems to have slowed, with “only” 16 released in the last quarter of the year. Four of the recent EOs could impact drug and device companies in a myriad of ways.

For individuals with major depressive disorder (MDD) that does not respond to pharmacotherapy, recent decisions by the U.S. FDA enabling at-home use of neuromodulation devices may provide a bright spot in dark days. Neurolief Ltd. received FDA premarket approval for Proliv Rx, a physician-directed, brain neuromodulation therapy indicated for use as an at-home adjunctive treatment for adults with MDD who failed to respond adequately to at least one previous antidepressant on Jan. 7. That decision follows the December 510(k) clearance for at-home use of the Flow brain-stimulation device by Flow Neuroscience AB as either a monotherapy or as an adjunctive treatment.

Naox Technologies SAS secured U.S. FDA 510(k) clearance for Naox Link, its in-ear electroencephalography (EEG) device for clinical use both at home and in health care settings. Naox Link is a pair of earbuds the company hopes will transform how the brain activity is monitored, helping diagnose and track a number of conditions affecting the brain.

Nia Therapeutics Inc. reported data from an in vivo study of its Smart Neurostimulation System, an AI-based brain-computer interface (BCI), which demonstrated its ability to perform chronic sensing, neural-state decoding and programmable stimulation.

A review of 2025's noteworthy advances in medical research, including GLP-1 receptor agonists as anti-aging drugs, tumor-agnostic therapies and xenotransplants.

Gene editing technologies are moving forward in preclinical development with innovative strategies designed to treat diseases at their root and even reverse them.
