A new study reports that blood tests can help build a rough 'clock' for Alzheimer's, potentially predicting when symptoms will emerge. While not precise enough to map an individual trajectory, the approach could improve early diagnosis and inform preventive treatments.
A Nature Neuroscience study reveals a mathematical flaw in lesion network mapping, producing nearly identical brain networks across diverse conditions and challenging the validity of disease-specific targets, prompting calls for revised methods and cautious clinical application.
Scientists at Stanford have developed a new imaging technique called computational scattered light imaging (ComSLI) that allows detailed visualization of microscopic fiber networks in human tissues, which could lead to better understanding of diseases like Alzheimer's and other neurological disorders. The method is accessible, requiring only a simple setup with a light source and microscope camera, and can analyze existing tissue samples with high resolution, opening new avenues for research and diagnosis.
Walter Koroshetz, director of the NIH's National Institute of Neurological Disorders and Stroke, is leaving his position after his reappointment request was denied, contributing to leadership instability across nearly half of NIH divisions.
Early detection of neurological issues like tremors, memory lapses, stroke symptoms, and subtle seizures is crucial for effective intervention and better outcomes, emphasizing the importance of public awareness and timely medical evaluation.
A study suggests that restless legs syndrome (RLS) is associated with an increased risk of developing Parkinson's disease, but this risk decreases in patients treated with dopamine agonists, indicating a complex relationship possibly involving factors beyond the dopaminergic pathway. The findings highlight the importance of understanding the underlying mechanisms linking RLS and Parkinson's.
Researchers have developed a novel ultrasound helmet that can non-invasively target and modulate deep-brain structures with high precision, potentially transforming the study and treatment of neurological and psychiatric conditions like Parkinson's disease and depression.
Researchers from UCL and Oxford have developed a non-invasive ultrasound helmet capable of precisely stimulating deep brain regions, such as the thalamus, without surgery, opening new avenues for neuroscience research and treatment of disorders like Parkinson's disease. The device uses 256 elements to focus ultrasound beams, demonstrated to modulate neural activity in human volunteers, with potential for clinical applications and personalized therapies.
A new AI framework called CTCAIT can detect neurological disorders like Parkinson's, Huntington's, and Wilson disease with over 90% accuracy by analyzing speech patterns, offering a promising non-invasive tool for early diagnosis and monitoring across multiple languages.
Research shows that supplementing with precursor compounds 4-HMA and 4-HB can boost CoQ10 levels, potentially treating neurological symptoms in inherited CoQ10 deficiency diseases, as demonstrated in mice and an 8-year-old patient, offering a promising new approach for these conditions.
World Brain Day 2025 emphasizes the importance of lifelong brain health, highlighting that neurological well-being begins from fetal development and requires proactive care across all ages. The event aims to raise awareness about neurological disorders, their impact, and the need for better education, research, and lifestyle choices to protect brain health globally.
Recent research reveals that dopamine in the brain not only diffuses broadly but also sends rapid, localized signals to nearby neurons, suggesting a more complex role in regulating behaviors and neurological conditions than previously thought.
Recent research from Sweden demonstrates that adult human brains continue to generate new neurons, particularly in the hippocampus, challenging the long-held belief that brain cell growth stops after childhood. The study analyzed over 400,000 individual cell nuclei, finding neural progenitor cells actively dividing in adults, which could have implications for treating neurological conditions and understanding brain plasticity. However, the extent and pattern of neurogenesis vary among individuals, raising further questions about its role in health and disease.
New research shows that hippocampal neurons can simultaneously respond to slow theta and fast gamma brain waves by switching between firing modes, using bursts for theta and single spikes for gamma, a phenomenon called interleaved resonance. This flexible coding mechanism enhances our understanding of brain functions like navigation and memory and has potential implications for neurological diseases such as Alzheimer's, epilepsy, and schizophrenia.
New research from the University of Pittsburgh reveals that the brain uses separate synaptic sites for spontaneous and evoked signaling, allowing it to balance stability with adaptability, which has implications for understanding learning, memory, and neurological disorders.
