Researchers at the University of Rochester Medical Center found that children who experience a mild traumatic brain injury are more likely to develop emotional and behavioral problems. The study, which analyzed data from thousands of children, revealed a 15-percent increased risk of these problems in kids with a mild TBI.
Researchers found that a common autism screening test consistently excludes more women than men from research studies, creating a 'leaky pipeline' for diagnosis and treatment. This bias is attributed to the test's origins in male-dominated samples, which may not accurately capture female phenotypes.
A new Canadian study has found that older people with insomnia are at greater risk of developing memory decline and long-term cognitive impairment such as dementia. Insomnia was specifically related to worse memory performance compared to those with some insomnia symptoms alone or no sleep problems.
Researchers have developed a novel DNA-based method to identify people at greater genetic risk of developing Alzheimer's disease before symptoms appear. The method uses data on common DNA variants from over 7.1 million individuals and predicts a person's risk of Alzheimer's, depending on which DNA variants they have.

A link to genetics research is also being explored to better understand genetic and environmental factors that influence cognitive and brain aging.
A study found that infants aged 5-8 months preferentially perceive faces in the upper visual field. The bias emerges around 7 months and is specific to faces, with no observed bias for non-face images. This suggests an important role of experience with faces in daily life in shaping this perceptual bias.

The partnership with Probably Genetic aims to screen undiagnosed patients and provide them with genetic testing resources, ultimately advancing treatment development for SYNGAP1.
A new study found that siblings of children with disabilities score higher in self-reported cognitive empathy than typically developing peers. This may be due to the specific 'advantage' of cognitive empathy in understanding and supporting their sibling relationship.
A new study found that siblings of children with disabilities exhibit greater cognitive empathy, understanding their sibling's thoughts and feelings. This increased empathy is linked to improved social skills and prosocial behavior in these individuals.
A new study on culture and cognition found that long-term Hispanic immigrants who were less acculturated performed significantly worse on cognitive function tests than their highly acculturated peers. The study assessed the acculturation levels and cognitive function of over 600 Hispanics age 60 or older.

A new UCSF study found that the neural connections of newborns with two different kinds of brain injuries were linked to significantly different developmental outcomes years later. CHD newborns had worse language function at 12-18 months and worse cognitive, language, and motor function at 30 months compared to HIE infants.
Researchers found that infants with autism symptoms can show significant improvement in just a few months through targeted therapeutic interventions. The studies suggest that bridging the gap between early detection and intervention may significantly reduce the severity of lifelong developmental deviation.
