Developmental disorder discovery could lead to better treatments for Rett syndrome

New discoveries about the severe developmental disorder known as Rett syndrome could open the door to better treatments for the devastating, life-shortening condition.

New study reveals how brain stimulation improves cognition, decision-making in mental health disorders

Researchers have uncovered important insights that could improve how mental health conditions are treated with brain stimulation therapy — a treatment where electrical signals are used to stimulate specific parts of the brain.

‘Dancing the blues away’ seen in brain imaging in people with Parkinson’s disease, new study finds

Dancing lowers the depression associated with Parkinson’s disease, and the benefits can be seen in multiple ways, a new study shows.

Dyslexia genetics linked to brain structure

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study, a team of scientists found that genetic variants that increase…

Sleep apnea linked to changes in the brain

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a new study. The study, which included mostly Latino people, also found that those with lower oxygen leve…

Bias in AI amplifies our own biases, researchers show

Artificial intelligence (AI) systems tend to take on human biases and amplify them, causing people who use that AI to become more biased themselves, a new study finds.

Study supports new blood-based biomarker to detect early brain changes leading to cognitive impairment and dementia

To identify and follow blood vessel-related changes in the brain that contribute to cognitive impairment and dementia, researchers and clinicians typically rely on MRI to evaluate ‘downstream’ biological markers — those at the end of a cascade of even…

More calories — more consumption: Individuals with and without obesity both prefer high-calories food, study finds

Higher calorie foods were preferred among individuals with and without obesity despite similar taste and texture, according to a new study.

Study sheds light on what causes long-term disability after a stroke and offers new path toward possible treatment

Researchers have revealed how an overlooked type of indirect brain damage contributes to ongoing disability after a stroke. The paper shows how the thalamus — a sort of central networking hub that regulates functions such as language, memory, attentio…

Teens with a reduced response to rewards are more susceptible to depression

Novel research shows that a reduced neural response to receiving rewards in teens predicts the first onset of depression, but not anxiety or suicidality. This is independent of pre-existing depressive or anxiety symptoms, as well as age or sex, which a…
