Current reporting, research and professional developments across Neuropsychology, curated for psychologists and behavioral-health professionals.
Summary: A new study uncovered a critical gene-environment interaction that influences early neurostructural and cognitive changes associated with Alzheimer’s disease long before clinical symptoms emerge. The research…
BackgroundPost-stroke cognitive impairment (PSCI) severely affects quality of life and prognosis in stroke survivors, yet reliable predictive, diagnostic and prognostic tools remain limited. Recent advances suggest that…
Post-traumatic stress disorder (PTSD) is associated with cognitive impairments, anxiety, fear extinction deficits, and neurobiological alterations, particularly in the hippocampus. Oxidative stress, reduced brain-derived…
Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets…
A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models. The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new…
Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This…
ObjectiveAcute high-altitude hypobaric hypoxia impairs executive functions, yet the dynamic relationship between behavioral performance and neuroelectric activity remains unclear. This study aimed to explore the neural…
BackgroundAging is associated with progressive alterations in behavioral function, yet majority of the studies interpret behavioral outcomes on an assay-by-assay basis, limiting understanding of how behavioral domains…
Summary: Researchers identified a new class of traveling brain waves that rotate over space and time. The study reveals that these vortex-like waves are driven by a unique, circular “merry-go-round” architectural layout…
Stephen Lankenau has spent years studying how people use cannabis in everyday life. As director of Drexel University’s Medical Cannabis Research Center, he has watched legalization spread, products ...
Xenopus laevis has long served as an important model for studies of embryonic development and is a cornerstone to our current understanding of cellular and molecular mechanisms underlying neurodevelopment, including the…
Diabetes and dementia appear to be closely intertwined, with each condition potentially influencing the other. Problems with insulin and glucose can affect the brain’s energy supply, increase inflammation, and damage…
Platforms in Toronto, London, and Hamilton aim to speed diagnosis, improve mental health care, and unlock the brain TORONTO, June ...
Background Emotion is a complex psychological phenomenon involving both arousal and valence. emotional processing (EP) refers to the ability to perceive and interpret emotional stimuli, such as facial expressions or…
A large-scale study suggests that men with higher levels of the amino acid tyrosine may have shorter lifespans, potentially losing close to a year of life expectancy. The finding is especially intriguing because tyrosine…
A copper-based compound restored the brain’s ability to clear toxic Alzheimer’s proteins, dramatically reducing amyloid buildup and improving memory in laboratory experiments. The findings point to a potentially…
Researchers discovered that mutations linked to blood cancers may help trigger Alzheimer’s disease by creating overly inflammatory immune cells in the brain. The unexpected finding could lead to new blood-based screening…
Physical health is important, but as we age - another big piece of the puzzle is protecting your mental health.
The transition to motherhood has been shown to result in significant changes in the structure and function of the brain, with particular emphasis on the enhancement of cognitive abilities that are essential for survival…
Doctors at Leuven University Hospital (UZ Leuven) can now detect signs of brain diseases such as Parkinson’s Disease, dementia and ALS (the neurodegenerative disease amyotrophic lateral sclerosis) ...
Background Understanding the neural maturation of emotional inhibitory control (IC) from adolescence to young adulthood is critical but remains incompletely characterized. The present study examined age-related…
Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became…
A major study suggests glucosamine, a popular supplement for joint pain, could be linked to faster progression from mild cognitive impairment to Alzheimer’s disease. Researchers found a 25% higher likelihood of…
A study of more than 2,100 adults found that eating more ultra-processed foods was linked to poorer attention and slower mental processing, even among people with otherwise healthy diets. Researchers also found higher…
Researchers have identified a new Alzheimer’s target and created an experimental compound that blocks a damaging process inside brain cells. In mice, the treatment slowed nerve cell loss, reduced Alzheimer’s-related…
Angiogenesis plays a vital role in cerebral tissue repair following ischemic stroke. Prior in vivo studies have identified astrocytic interleukin-17A (IL-17A) as a critical mediator of post-ischemic angiogenesis…
Mammalian models are widely employed in the research of human diseases. Behavioral tests in animals is a critical evaluative approach in scientific research, offering insights into complex disease pathophysiology and…
Clients or their families typically present with concerns about ADHD, learning disabilities, and autism. They are interested on ...
Add Yahoo as a preferred source to see more of our stories on Google. PLATTSBURGH — Nearly 60% of dementia caregivers say the ...
Scientists have uncovered evidence that autism may include at least two biologically distinct subtypes, each marked by a different pattern of brain communication. By combining brain scans from nearly 1,000 people with…
