Manipulating brain cells called astrocytes using light prevented the retention of fear memories long-term, according to new research. This opens the door to potential treatments for conditions like PTSD, which is characterized by abnormal fear memory.

Memories can form outside of the brain, according to new research. Non-brain cells exposed to chemical pulses similar to the ones that brain cells are exposed to when presented with new information caused the non-brain cells to switch on a gene critical for memory formation.

Researchers have developed an AI model that can spot bits of brain tumors that surgeons may miss while removing them from patients. It can detect these remaining tissues in as little as 10 seconds, and help prevent post-procedure complications.

While growing evidence suggests that there’s a link between blood iron levels and the development of Alzheimer’s disease, new research investigating the effects of an available iron-reducing drug has raised concerns about its use as a treatment for the condition.

Combining VR and non-invasive deep-brain electrical stimulation, has improved memory – the kind that remembers where you left the car keys - in healthy people. The approach has great potential as a surgery- and drug-free treatment for cognitive decline

Spanning nearly 100 laboratories in 45 countries, a landmark study has, for the first time, shown an association between genetic brain shape and size and the prevalence of neurological conditions such as Parkinson's disease and ADHD.

A recent clinical trial has shown that it's possible to safely and effectively treat depression at home using a brain stimulation device. That means patients can give themselves low-intensity impulses to see positive results with 30-minute sessions.

A non-invasive brain-computer interface that produces real-time EEG feedback on neural activity while the user plays a video-game, and then assesses data with AI, is helping clinicians more accurately diagnose attention-deficit/hyperactivity disorder.

In a much-needed update to 2003 data on attention-deficit/hyperactivity disorder in the US, a new report has found that 15.5 million American adults have been diagnosed with the condition – and many have been let down by poor access to treatment.

By obtaining high-resolution images of Alzheimer’s disease-affected brain cells as the condition progresses, researchers have identified the specific neurons that are damaged. The information the ‘cell atlas’ provides highlights potential new treatment targets.

A laser-led device that shoots light into the brain to test blood flow and volume can offer instant feedback on a patient's stroke risk and and provide a portable, affordable and non-invasive way for clinicians to make life-saving interventions.

An Oxford University study showed that playing the eponymous video game Powerwash Simulator showed a small improvement in the moods of more than 70% of its participants. In fact, it was found to be more effective than watching TV or reading.

A study conducted by researchers at Uppsala University shows that playing the popular video game Tetris can significantly reduce flashbacks in people suffering from post-traumatic stress disorder (PTSD).

Consuming an extra six serves of foods and drinks high in flavonoids – such as berries, tea, dark chocolate and, yes, red wine – could safeguard your brain in older age, with researchers finding a link between this plant component and dementia risk.

An innovative start-up is out to change how attention-deficit/hyperactivity disorder is managed, with non-invasive light electrical brain stimulation delivered by a headband worn for just 20 minutes a day that aims to improve poor executive function.
