A new study disputes the common belief that obtaining a higher education can help slow brain aging.
Combining brain scan images with machine learning, researchers identified a number of brain changes following TBI that share similarities with Alzheimer's disease. The findings add to the growing body of evidence that the two conditions follow the same trajectories.
Children who experience early life adversity experience faster biological aging than children with no history of exposure to abuse. Trauma was associated with biological aging in early puberty, cellular aging, and alterations in brain structure. The findings may explain why children who experienced adversity early in life often suffer poor health as they age.
First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population.
Cortical thickness and regional brain connectivity pay an equally important role in linking brain and behavior.
Slower walkers have accelerated aging in middle age, both physically and cognitively. Tests given to measure IQ, language, motor skills, and emotional control at age 3, can predict walking speed and thus accelerated aging during middle age.
Cortical anatomy is not represented by fixed differences between those with ASD and peers not on the autism spectrum. However, differences in symptom profiles and severity, age and cognitive ability are related to brain differences specific to ASD alone.
Neuroimaging reveals those who have spent more years studying have increased cortical thickness in the medial prefrontal cortex, anterior cingulate and orbitofrontal areas of the brain. Researchers also identified enhanced gene expression profiles in these brain regions that promote information processing and provide protection against some age-related neurodegenerative diseases.
A new study sheds light on the roles both genetics and neuroanatomy play in obesity. Researchers report those with higher BMI had reduced cognitive flexibility, reduced ability to delay gratification and worse verbal memory. Additionally, those with increased BMI have increased amygdala and left prefrontal cortex volume.
According to researchers, the adult brain may be sensitive to social and economic factors. Researchers report in middle age, better socioeconomic status is associated with more efficient brain network organization and thicker gray matter.
A new neuroimaging study reveals middle aged men who experience negative fateful life events, such as the death of a loved one or divorce, show signs of accelerated brain aging.
