Expert Identifies Irregular Brain Wave Patterns as Potential Indicator of ADHD

Credit: PixabayChildren with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue.The Neurological Basis of ADHDThe neurological variations in ADHD manifest as...

Adults Generate New Brain Cells, Which Play a Role in Enhancing Learning Through Listening

Credit: PixabayYour brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function?Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether...

Scientists Suggest that Adhering to this Diet may Help Slow Cognitive Decline

A study published in Neurology suggests that closely following the MIND diet may lower the risk of cognitive impairment, with a stronger effect observed in women and Black participants. While the study shows an association between the diet and reduced risk, it does not prove causation. Credit: PixabayA study published in Neurology, the journal...

Five Distinct Patterns of Brain Aging Uncovered by 50,000 Scans

Some parts of the brain tend to atrophy and deform in concert with other regions. Credit: Zephyr/SPLA comprehensive analysis of nearly 50,000 brain scans has identified five unique patterns of brain atrophy linked to aging and neurodegenerative diseases. The study also connected these patterns to lifestyle factors such as smoking and alcohol consumption, as...

Scientists Identify Key Brain Network for Creativity

Credit: PixabayNeuroscientists believe they have pinpointed the extensive neural network that fuels the brain's creativity. Unlike specific movements or sensory responses, creative thinking is not limited to a single area of the brain's outer cortex. However, researchers from Baylor College of Medicine have identified the brain circuits crucial to certain types of creative thought.When...

New Compound Restores Memory Function in Alzheimer’s Cases

A new molecule that switched memory and cognition back on in mice with Alzheimer's could one day do the same for humans, as illustrated in this generative imageInstead of focusing on fighting the plaques associated with Alzheimer's, researchers decided to explore the possibility of increasing electrical oscillations in the brain. They created a molecule...
