Researchers have published a study in Science Advances that looks into the genetic mechanisms behind the development of schizophrenia.

Students whose brainwaves are more in sync with their classmates and teacher are likely to learn better than those lacking this “brain-to-brain synchrony,” shows a new study by a team of psychology and education researchers. The findings, which appear in the journal Psychological Science, offer new insights into the learning process. 

Scientists are testing a new personalized immunotherapy approach that is designed to work similarly to a vaccine by training the immune system to fight glioblastoma brain cancer.

People experiencing hearing loss who are not using a hearing aid may have a higher risk of dementia than people without hearing loss, suggests a new study published in The Lancet Public Health journal. However, using a hearing aid may reduce this risk to the same level as that of people without hearing loss.

Researchers have shown for the first time that in middle-aged men, Obstructive Sleep Apnea may cause early cognitive decline, even in patients who are otherwise healthy and not obese.

In a new study, teens who added walnuts to their diet for 100 days showed improvements in attention function, and for those with ADHD, frequent walnut consumption was associated with improvements in behavior. Researchers also noted an increase in fluid intelligence in those who frequently consumed walnuts as part of their daily diet.

Listening to or practicing music had positive implications on cognitive decline in older adults by stimulating the production of gray matter in key brain areas, a new study reveals.

Researchers have used machine learning to investigate the molecular and neural mechanisms that could underlie differences among individuals diagnosed with autism spectrum disorder (ASD). Their paper, published in Nature Neuroscience, identifies different subgroups of ASD associated with distinct functional connections in the brain and symptomatology, which could be related to the expression of different ASD-related genes.

A novel imaging technique is capable of showing reactive astrocyte-neuron interactions. The technique sheds new light on Alzheimer’s pathologies and offers a potential breakthrough for the diagnosis and treatment of dementia.

An international team of 79 researchers has collaborated on a study published in Nature Medicine to delve into perivascular spaces (PVS), a poorly understood artifact seen in magnetic resonance imaging of cerebral small vessel disease, a leading cause of stroke and dementia.

Finally this week, new research findings show that probiotic supplementation could be a positive strategy to counteract oxidative stress and inflammation promoted by sleep loss.
