Cognitive decline may be detected using network analysis, according to Concordia researchers

Researchers use network analysis to study whether it can reveal the subtle changes associated with subjective cognitive decline that cannot otherwise be detected through standard test analyses. By running a statistical analysis of data merged from two large Canadian data sets, the researchers were a...

Blended antioxidant supplement improves cognition and memory in aged mice

Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant imp...

Memory self-test via smartphone can identify early signs of Alzheimer's disease

Dedicated memory tests on smartphones enable the detection of 'mild cognitive impairment', a condition that may indicate Alzheimer's disease, with high accuracy.

Large-scale animal study links brain pH changes to wide-ranging cognitive issues

The International Brain pH Project Consortium unveils groundbreaking findings in a large-scale animal model study, indicating altered brain pH and lactate levels as a transdiagnostic endophenotype in neuropsychiatric disorders with cognitive impairment. This collaborative effort, involving 131 resea...

Parental perceived immigration threat and children’s mental health, self-regulation and executive functioning in pre-Kindergarten.

Many children in immigrant households endure unique stressors shaped by national, state, and local immigration policies and enforcement activity in the United States. Qualitative studies find that during times of heightened immigration enforcement, children as young as 3 years of age show signs of b...

Suicidal ideation in Iraq and Afghanistan veterans with mental health conditions at risk for homelessness.

Suicide prevention among Veterans is a national priority. Overlap exists between conditions that may increase risk for suicide (e.g., mental health conditions, financial stressors, lack of social support) and homelessness among Veterans. We examined predictors of variance in suicidal ideation (SI) a...

A novel model of obesity prediction: Neurobehaviors as targets for treatment.

Obesity is a worldwide epidemic that is on the rise, with approximately 30% of the world population classified as either overweight or obese. The United States has some of the highest rates of obesity, and in most countries in the world, obesity now poses more of a serious health concern than malnut...

The rodent lateral orbitofrontal cortex as an arbitrator selecting between model-based and model-free learning systems.

Our understanding of orbitofrontal cortex (OFC) function has progressed remarkably over the past decades in part due to theoretical advances in associative and reinforcement learning theories. These theoretical accounts of OFC function have implicated the region in progressively more psychologically...

Alzheimer’s gene triggers early breakdowns in blood-brain barrier, predicting cognitive decline

New USC research reveals how APOE4, a genetic culprit for Alzheimer's disease, triggers leaks in the brain's plumbing system, allowing toxic substances to seep into the brain areas responsible for memory encoding and other cognitive functions.
The damage is linked to future problems i...

Implant-free optogenetics minimizes brain damage during neuronal stimulation

A minimally invasive optogenetic technique that does not require brain implants successfully manipulated the activity of neurons in mice and monkeys, researchers report April 29th in the journal . The researchers first genetically engineered neurons to produce a newly developed, extremely light-s...
