Childhood experiences shape the brain’s white matter with cognitive effects seen years later

Investigators have linked difficult early life experiences with reduced quality and quantity of the white matter communication highways throughout the adolescent brain. This reduced connectivity is also associated with lower performance on cognitive ta…

First insights into how excitatory and inhibitory brain signals change as people age using wearable scanner

A study has shown how aspects of brain function change with age, revealing that excitatory processes in the brain decrease, while inhibitory processes increase as children get older. The findings are an important step in understanding conditions like a…

Brain’s own repair mechanism: New neurons may reverse damage in Huntington’s disease

New research shows that the adult brain can generate new neurons that integrate into key motor circuits, findings that may point to a new way to treat neurogenerative disorders.

Molecules that fight infection also act on the brain, inducing anxiety or sociability

Scientists find the protein IL-17 that fights infection also acts on the brain, inducing anxiety or sociability. This adds to evidence that immune molecules can influence behavior during illness.

Exposure to air pollution may harm brain health of older adults

Long-term exposure to high levels of air pollution may harm the brain health of older adults in England, finds a new study.

Could targeting Parkinson’s outside of the brain improve symptoms?

Parkinson’s doesn’t just affect movement and the brain — it may also impact the heart, according to new research. Scientists suggest that targeting a key protein outside of the brain could help manage Parkinson’s-related heart issues.

17 modifiable risk factors shared by stroke, dementia, and late-life depression

In a new extensive systematic review, researchers identified 17 modifiable risk factors that are shared by stroke, dementia, and late-life depression. Modifying any one of them can reduce your risk of all three conditions. The findings provide evidence…

Key differences between visual- and memory-led Alzheimer’s discovered

Differences in the distribution of certain proteins and markers in the brain may explain why some people first experience vision changes instead of memory loss in Alzheimer’s disease, finds a new study.

Medicinal cannabis is linked to long-term benefits in health-related quality of life, study finds

Patients prescribed medicinal cannabis in Australia maintained improvements in overall health-related quality of life (HRQL), fatigue, and sleep disturbance across a one-year period, according to a new study. Anxiety, depression, insomnia, and pain als…

How the brain evaluates rewards

Researchers have gained a new understanding of how the brain processes reward and risk information. Neuroscientists show how nerve cells in the so-called amygdala not only encode the probability and magnitude of rewards, but also dynamically process th…
