New research has found that the loss of social memory – recognizing friends and family – in Alzheimer's disease (AD) could come down to specific structures around brain cells. And targeting this delicate scaffolding may potentially prevent this heartbreaking stage in cognitive decline.

Sleep isn't just rest, it's a crucial biological process. New MIT research has revealed why sleep deprivation causes attention slips. It found brain fluid surges usually reserved for sleep time occur during waking hours, throwing one's ability to focus

Researchers have uncovered a shared brain cell breakdown mechanism behind Alzheimer’s and Parkinson’s diseases, revealing how two different proteins can disrupt neurons in the same devastating way.

Smaller than a grain of salt and possibly the tiniest neurotech implant ever invented, the MOTE sends neuro-telemetry data via infra-red lasers, and could help neuroscientists unlock cures for neurological diseases.

While not everyone with attention-deficit/hyperactivity disorder has tapped into their creative side, there are a lot of creative people who also have neurodivergent brains. Now, new research suggests this could be due to the way our minds wander.

A new study has pinpointed how the APOE4 gene variant sabotages the brain’s energy balance, blocking neurons from burning fat for fuel when glucose runs low, a discovery that could reveal new ways to prevent or slow Alzheimer’s disease.

Lead poisoning isn’t just an industrial-age problem. A new study reveals our ancestors, including Neanderthals, were exposed to lead for millions of years, shaping how their brains evolved and overturning what scientists thought about our toxic history.

A new study offers hope for brain cancer patients facing memory loss from radiotherapy. By blocking a single immune receptor, scientists preserved cognition in mice without dulling the cancer-killing power of radiation.

Time availability can impact the development of dementia perhaps as much as diet and exercise, according to a panel of scientists. The group says its research should cause a paradigm shift in the diagnosis and treatment of the condition.

A new study found stranded dolphins show brain damage eerily similar to that of people with Alzheimer's. Just like people with dementia sometimes wander far from home, scientists think dolphins with Alzheimer's might get confused at sea.

A new study suggests that a father’s COVID-19 infection could do more than make him sick – it may leave epigenetic marks on his sperm that pass anxiety to his offspring, revealing how viral infections can echo across generations.

We've all experienced defeat at some point – losing a game, a potential new job, a debate. Now, a new study has found that the brain may learn from losing to others, with a specific group of neurons tied to defeat that then changes our future behavior.
