Scientists at UCL used machine learning to analyze blood tests and brain scans from 634 MS patients, discovering two distinct subtypes of the disease with different progression patterns, which could lead to more personalized treatment approaches.
Scientists have identified two new biological subtypes of multiple sclerosis using AI, blood tests, and MRI scans, which could lead to more personalized and effective treatments for patients by better understanding disease progression and tailoring therapies accordingly.
A study reveals that ADHD medications like Ritalin and Adderall primarily boost alertness and motivation by affecting brain reward and wakefulness systems, rather than directly improving attention, and may mimic sleep effects, raising concerns about sleep deprivation in diagnosis and treatment.
Scientists have identified a gradient in the hippocampus that responds to familiar and new environments, which could help explain early signs of dementia like Alzheimer's, by revealing how the brain processes spatial novelty and familiarity during navigation.
A study finds a link between gum disease and increased white matter hyperintensities in the brain, which are associated with memory, balance, and stroke risk, suggesting oral health may impact brain health, especially in older adults.
A study by McGill University found that using the BrainHQ app for 10 weeks can reverse a decade of decline in a key brain system related to attention and memory in older adults, showing promising but preliminary evidence of cognitive benefits.,
New guidelines for diagnosing multiple sclerosis (MS) allow for earlier and more accurate detection, even before symptoms appear, by using advanced imaging techniques and updated criteria, which can lead to earlier treatment and better outcomes.
A study using ultra-high field MRI found that individuals with major depressive disorder and higher neuroticism scores have a thinner parahippocampal cortex, suggesting this brain region could serve as a biomarker for depression and related traits.
Research shows that the COVID-19 pandemic has accelerated brain aging by about five and a half months on average, even in individuals who did not contract the virus, likely due to stress, isolation, and uncertainty. The study suggests these changes might be reversible, and highlights the broader impact of environmental and social factors on brain health.
A study shows that living through the COVID-19 pandemic, even without infection, subtly accelerated brain aging due to stress, social upheaval, and economic hardship, with infected individuals experiencing additional cognitive decline. The findings highlight the importance of lifestyle factors and social support in mitigating these effects and suggest potential for using brain age as a marker in public health.
A study suggests brain imaging can identify individuals with trauma-related symptoms who are most likely to benefit from MDMA treatment, showing that those with heightened brain reactivity to threats experience significant neural and behavioral changes, paving the way for personalized psychiatry approaches.
Researchers at Mayo Clinic have developed an AI tool called StateViewer that accurately detects nine types of dementia from a single brain scan, improving speed and precision in diagnosis, which could lead to earlier and more effective treatments.
A study comparing brain scans of psychopaths and non-psychopaths found that individuals with psychopathic traits have structural differences in brain regions associated with emotional regulation, impulsivity, and behavioral control, including smaller overall brain size and specific regional reductions, which could inform future treatments and understanding of psychopathy.
MIT researchers found that ChatGPT users show weaker neural connectivity and decreased engagement in brain activity, raising concerns about AI's negative effects on cognition and mental health, including dependency and potential atrophy of critical thinking skills.
A study from MIT indicates that using generative AI tools like ChatGPT reduces neural connectivity and cognitive engagement, potentially impairing memory and original thinking, especially in educational settings. Search engines also impact brain activity but to a lesser extent, raising concerns about widespread AI reliance affecting cognitive independence.
