The first-of-a-kind brain-stimulation device approved to treat attention-deficit/hyperactivity disorder in the US has had its efficacy questioned, with scientists believing that its Food and Drug Administration approval was based on poor science.

Researchers in Switzerland have stuffed a bunch of chips and sensors into socks to help people who suffer from some of the worst symptoms of diabetes – chronic pain and a loss of sensation in the feet that make it hard to walk.

A new biocompatible polymer that helps glue and repair tissue without causing damage – initially developed at MIT – might be a better way to heal wounds than sutures and staples. When activated using blue light, it can securely attach to wet tissue.

In the ongoing search to find an intervention that does away with opioids, a new game-based system has shown huge promise in tackling chronic neuropathic pain. Using a game and a headset, it "trains" patients to rewire brain signals to relieve pain.

Pupil dilation and subtle facial changes in response to sound can reveal how severe tinnitus is. Through this, researchers have discovered a new way to objectively gauge how bad the condition is, more accurately diagnosing tinnitus and treating it.

A group of Texas-based researchers has developed an effective way to treat post-traumatic stress disorder that involves zapping the vagus nerve around the neck, using a device the size of a shirt button.

Nerve or neuropathic pain has long been a tricky condition to treat effectively. However, a new study has comprehensively evaluated current drug and non-drug therapies to provide up-to-date guidelines to inform treatment options.

More than a million people of nearly all ages lace up their trainers and hit the pavement in a marathon every year. And while running has a suite of health benefits, a long-distance race may not be such good news for the brain in the weeks that follow.

If you're thinking of getting an injection for back pain, you might want to think again. A panel of experts has examined the practice, found serious issues with its use – including financial gain – and issued strong recommendations to avoid it.

A pioneering once-a-day pill that regenerates nerve cell connections damaged by ALS has been FDA-approved for ongoing clinical trials. The drug is now being given to those with ALS and could be a watershed moment in the treatment of the fatal disease.

Nature has again proven effective in treating health conditions, this time nerve injury. According to a new study, a compound found in the blessed thistle plant accelerates the regeneration of damaged nerves, restoring motor function and touch sensation.

Researchers discovered a non-opioid compound that effectively reduced hypersensitivity associated with nerve pain caused by diabetes or chemotherapy drugs, opening the door to a drug to treat the condition for which existing painkillers do little.
