An intriguing study has identified a protein produced by the liver after exercise that could protect the brain from cognitive decline. The study points to the possibility of developing a drug to generate this same effect without the need for exercise.

New research is uncovering how non-alcoholic fatty liver disease influences the neurological conditions associated with Alzheimer’s disease. The study describes how a protein produced in the liver can travel to the brain and trigger neuroinflammation.

Strokes can leave lifelong lingering issues, as neurons are damaged and die. But now, researchers at the University of Pittsburgh have identified a new drug that could help prevent damage even after a stroke, with tests in mice showing promise.

New imaging research is offering insights into the relationship between Alzheimer’s and abnormal accumulations of iron in the brain. The study confirms a correlation between high iron deposits in some brain regions and rates of cognitive decline.

New data reporting the long-term effects of deep brain stimulation on early-stage Parkinson’s patients has found the treatment significantly slows the progression of the disease. A large Phase 3 trial is now underway to verify these findings.

The human brain reacts completely differently to a threat that invades your personal space compared to those that are further away, according to a new study that combined MRI scans with VR technology.

Tens of billions of cells in your body die everyday. It’s a natural process, important for keeping the body healthy. Now, in a world first, researchers have directly imaged the death of neurons in mice, and as how the body clears them out afterwards.

Scientists are already struggling to make headway in the fight against dementia, and the discovery of a new more aggressive form of neurodegeneration that's often misdiagnosed as Alzheimer's disease further complicates the problem.

A new brain imaging study, examining cognitively healthy middle-aged subjects, is suggesting lower levels of estrogen in women post-menopause could play a role in triggering brain changes linked to Alzheimer’s disease.

A tiny brain lesion can shift a person's reality in bizarre and tragic ways, and their ability to describe their condition can lead us toward a fuller understanding of how our complex mental processes work. Here's another oddity to put on the pile.

Scientists have successfully bridged the gap between organic and artificial. A team has created biohybrid synapses that let living cells communicate with electronic systems, not with electrical signals but with neurotransmitters like dopamine.

A new Johns Hopkins study, looking at how psilocybin influences a mysterious brain region called the claustrum, is just one of several compelling recent articles shining a light on how our brains generate our experience of consciousness.
