Newsweek: Smoking linked to calcium deposits in part of brain in charge of memory

Smokers are more likely to have calcium in a part of the brain in charge of memory, according to researchers. In a study involving almost 2,000 people who attended a memory clinic at a Dutch hospital, almost a fifth had higher than average levels of calcium build-up in their hippocampus. However, the scientists did not […]

News-Medical: Researchers discover unique process of brain cell death in MS

Researchers at the University of Alberta have discovered a unique process of brain cell death that affects the cells that are most vulnerable in multiple sclerosis (MS). After identifying the process called pyroptosis, or fiery death, the researchers were able to block the enzyme in the brain that is responsible for it, using a drug […]

ALS News Today: Changes in brain structure, blood flow linked to varying cognitive deficits in ALS

Cognitive deficits associated with amyotrophic lateral sclerosis (ALS) are linked to a particular pattern of abnormal changes and altered blood flow in specific brain regions, a study shows. The study titled “Brain Structural and Perfusion Signature of Amyotrophic Lateral Sclerosis With Varying Levels of Cognitive Deficit” was recently published in the journal Frontiers in Neurology. […]

News-Medical: Study shows how amyloid aggregates alter brain cells in Alzheimer’s disease

Researchers from CNRS and the Université de Bordeaux have revealed the mechanism through which amyloid peptide aggregates alter brain cells to cause the harmful effects seen in Alzheimer’s disease. As described in the journal Cell Reports, the aggregates alter the normal function of connections between neurons by interacting with a key enzyme of synaptic plasticity. […]

Science Daily: Scientists unravel molecular mechanisms of Parkinson’s disease

Detailed brain cell analysis has helped researchers uncover new mechanisms thought to underlie Parkinson’s disease. The study, published in Nature Communications, adds to our growing understanding of the causes of Parkinson’s and other neurodegenerative diseases, and could influence drug design in the future. For years, scientists have known that Parkinson’s disease is associated with a […]

ADDitude: What is brain training for ADHD

Unsure what constitutes brain training? You are not alone. This alternative treatment means different things to different people, and encompasses a wide range of programs — some more reputable than others. (June 11, 2018) Read the full article here

Medical Xpress: Investigators suggest that brain circuits could unlock new psychiatric treatments

A McLean Hospital scientific team’s comprehensive analysis of recent research into how the brain shapes responses to cognitive and emotional challenges has revealed the potential for new brain treatments for psychiatric conditions that target specific brain circuits. The detailed review is available online in the journal Trends in Pharmacological Sciences. (June 11, 2018) Read the […]

Live Science: How drug addiction hijacks the brain

You’ve probably heard of the brain’s reward network. It’s activated by basic needs — including food, water and sex — and releases a surge of the feel-good neurotransmitter dopamine when those needs are met. But it can also be hijacked by drugs, which lead to a greater dopamine release than those basic needs.But the reward […]

News-Medical: Computerized brain shows how depressive episodes affect memory

It was already known that people who suffer an acute depressive episode are less likely to remember current events, but the new model suggests that older memories are also affected. During a depressive episode, the brain’s ability to produce new brain cells is reduced. In major depressive disorder, patients can suffer from cognitive impairment so […]
