Mini human brains, grown from stem cells and implanted into living mice, have for the first time been shown to respond to things the mice were seeing. Scientists were able to watch the responses in real time thanks to specialized graphene electrodes.

New research presents the most comprehensive study to date into the long-term neurological problems associated with COVID-19. Tracking 150,000 COVID patients for a year the research found COVID led to a 42% increase in risk of several brain disorders.

A study has found COVID-19 nearly doubles a person’s risk of developing Alzheimer’s disease in the year following infection. The findings add to a body of research indicating SARS-CoV-2 infections can affect progression of neurodegenerative disease.

A hormone released by muscles during exercise has been found to reduce levels of a protein associated with Parkinson’s disease. The promising animal study indicates future therapies may be developed based on the way this hormone improves brain health.

We all know a good, long walk in nature can be relaxing, but a landmark new study offers some of the first causal evidence to show exactly how a one-hour walk in the forest reduces activity in brain areas responsible for processing stress.

New research has offered the most comprehensive look at the long-term neurological effects of COVID-19 to date, tracking more than one million people and finding increased rates of dementia can be detected up to 24 months after the acute disease.

Scientists in Israel have demonstrated a promising new technology for early Parkinson's diagnosis, using a variation of MRI to spot tiny, telltale structures forming deep in the brain as the disease progresses.

New research has found an increased risk of several neurological disorders in patients following a bout of COVID-19. The study found the risk of Alzheimer’s, Parkinson’s and stroke all increased in COVID-positive subjects compared to those uninfected.

Following yet another failed clinical trial testing a drug designed to break up the aggregations of proteins thought to be the cause of Alzheimer’s, a new study suggests we look to a different part of the brain in the hopes of finding a treatment.

Arkenlight and Axorus have teamed up to prototype the first artificial neuron powered by a diamond betavoltaic battery made from nuclear waste. The goal is to develop medical-grade implants with energy sources that will last decades without charging.

A new study has found the type 2 diabetes significantly accelerates brain aging. While the pattern of neurodegeneration is similar to normal brain aging, it was found to progress around 26 percent faster in those with the largely preventable disease.

New research has found the world’s first portable MRI machine can accurately detect ischemic strokes. The machine was authorized by the FDA in 2020 and researchers are increasingly demonstrating it to be as effective a tool as bigger MRI devices.
