Mid-life moderate + vigorous physical activity quota associated with brain power

Research published in the Journal of Epidemiology & Community Health found that daily moderate and vigorous physical activity is positively associated with mid-life brain power. However, replacing these activities with just 6-7 minutes of sedentary behavior negatively impacts cognitive performance. The study analyzed data from over 4,4...

Premature birth linked to poorer school grades in adolescence

A large Danish population study found that premature birth before 34 weeks is linked to lower scores in maths and language tests as a teenager. However, the researchers noted that cognitive outcomes are not predetermined at birth but are heavily influenced by social circumstances.

Study shows SMART Recovery holds potential to help LGBTQ population with alcohol, substance use

A University of Kansas study found that SMART Recovery holds promise in addressing specific concerns of the LGBTQ population, but improvement is still needed. Participants appreciated being part of an LGBTQ-specific group, but faced challenges such as emotion regulation, coping with stigma, and recalling cognitive tools.

I do not see, I do not hear, but I know

A new study by Italian neuroscientists found that blind and deaf individuals' brains possess an innate functional architecture for integrating sensory information. This suggests that brain architecture can develop independently from sensory experience, adding weight to the 'nature versus nurture' debate.

Aging | DNA methylation-based measures of biological aging and cognitive decline over 16-years: preliminary longitudinal findings in midlife

A 16-year longitudinal study found associations between DNA methylation-based measures and neuropsychologically-validated cognitive decline in midlife. The results suggest that these measures may serve as biomarkers for a molecular aging mechanism, potentially identifying individuals at risk of cognitive impairment and dementia.

New findings on memory impairment in epilepsy

Researchers at the University of Bonn discovered that people with chronic epilepsy may have impaired dendritic integration, leading to less specific place cell firing and reduced ability to distinguish familiar from unfamiliar places. Administering a sodium ion channel inhibitor improved memory in animal models.

Researchers map deep brain stimulation target for Alzheimer's disease

A recent study suggests that stimulating the intersection of two particular brain networks correlated with better patient outcomes than stimulating nearby sites for patients with Alzheimer's disease. Cognitive improvement was associated with DBS to the direct interface between the fornix and bed nucleus of the stria terminalis.

Researchers gain a better understanding of how the most commonly used ADHD medication works

A new study has shed light on how the most commonly used ADHD medication, methylphenidate, works in the brain. The research found that methylphenidate increases dopamine levels in the nucleus accumbens and improves coordinated brain network activity, resulting in more stable sustained attention in children with ADHD.

New research can help older adults plan for changes in driving and firearm use

A new study explores how older adults plan for future changes, such as stopping driving or using firearms. The research found that reducing access to potentially dangerous situations should be prompted by declining ability, not age alone. Trusted messengers like family and clinicians can lead conversations around limiting access, and s...

Corporal punishment affects brain activity, anxiety, and depression
