To break down toxic proteins more quickly, immune cells in the brain can join together to form networks when needed. However, certain mutations associated with Parkinson’s disease can impair this process.
New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
New research has identified specific drug targets within the neural circuits that encode memories, paving the way for significant advances in the treatment of a broad spectrum of brain disorders.
Pioneering research shows that dopamine levels increase in response to stressful stimuli, and not just pleasurable ones, potentially rewriting facts about the “feel-good” hormone—a critical mediator of many psychiatric diseases. This discovery is cause to rethink treatment for psychiatric disease and addiction.
A new study links viral infections including mononucleosis and pneumonia experienced during adolescence with an increased risk of developing multiple sclerosis.
Researchers have discovered a new gene therapy pathway that has uncovered an important regulatory mechanism to keep our genome healthy. This pathway has the potential to protect us against serious life-limiting diseases such as cancer and dementia.
Neuroscientists have discovered specific types of neurons within the memory center of the brain that are responsible for acquiring new associative memories.
Amyloid protein made in the liver can cause neurodegeneration in the brain, according to a new study in the open-access journal PLOS Biology. Since the protein is thought to be a key contributor to development of Alzheimer’s disease (AD), the results suggest that the liver may play an important role in the onset or progression of the disease.
Higher glucose levels detected by a two-hour glucose test were an accurate predictor of poorer performance in tests of episodic memory ten years later, according to new research.
A worsening cardiovascular profile after menopause may contribute to the fact that women are disproportionately affected by dementia. A new study identified a link between cardiovascular fat volume and radiodensity and cognitive function, as well as racial differences in this association.
Finally this week, a new study finds dopamine increases responses to stressful stimuli, not just pleasurable ones. The findings could have implications for the treatment of mental health disorders and addiction.
