Using brain imaging, researchers have found that obsessive-compulsive disorder affects particular areas of the brain involved in processing certainty during the decision-making process, providing greater insight into this enigmatic condition.

A new study has revealed how the mutated proteins that are a hallmark of Parkinson’s disease spread and aggregate in the brain. The finding opens the door to developing a way of halting the disease’s progression.

Scientists have discovered how a unique kind of cell death, due to iron toxicity, creates a snowball effect that advances cognitive decline. With this finding, a whole new approach to treatment could be developed.

A study has found that some gastrointestinal disorders are associated with an increased risk of developing Parkinson’s disease. The research provides further evidence to support the hypothesis that the neurodegenerative disorder begins in the gut.

Multiple sclerosis sufferers can experience long periods of remission, but increasingly damaged nerves make relapses more frequent and severe. Scientists now believe, with a little molecular encouragement, those damaged nerves can heal themselves.

Six million Americans are living with Alzheimer’s disease, and with it comes the physical behaviors that are responsible for 80% of nursing home admissions. Researchers believe fasting set to circadian rhythms could alleviate these awful side effects.

It's enough to give you heartburn: previously linked to a higher risk of stroke and heart attack, the prolonged use of common, popular acid reflux medicines has now been connected to an increased likelihood of developing age-related dementia.

A million Americans are living with Parkinson’s disease, a neurological condition that, as it progresses, robs people of their quality of life. Now, a new mechanism has been uncovered that could potentially be treated to slow neurological decline.

The blood-brain barrier performs a vital function in keeping out toxins and pathogens, but it can become “leaky.” Now Stanford scientists have identified therapeutic molecules that could help patch it up, to potentially prevent neurological diseases.

Molecular imaging technology has shown the crucial role maternal vitamin D levels play in the early development of the brain cells that produce dopamine. The finding provides a greater understanding of the mechanisms underlying schizophrenia.

There may be new hope for people afflicted with Tourette's syndrome, in the form of a wrist-worn device. In a test of the technology, the majority of participants experienced a reduction in tic severity of at least 25%.

Scientists have developed a new technique that could eventually lead to new potential treatments for Alzheimer’s disease. The team investigated a compound that breaks down a protein associated with the disease, with tests in mice improving symptoms.
