Researchers found that factors such as age, hallucinations, and cerebral hemorrhage during surgery were associated with a higher risk of dementia.
A study found that middle-aged women are more likely to have changes in the brain related to Alzheimer's disease, even when controlling for age and other factors. The researchers suggest that hormonal changes during menopause may play a role in this increased risk.
Researchers found subtle brain changes in female college rugby players, including microstructural changes in white matter and differences in brain connectivity. The study suggests that repetitive impacts from playing a contact sport can affect the brain, even without a diagnosed concussion.
A recent meta-analysis found that the treatment gap between men and women for stroke has narrowed to 13%, with most studies showing differences of less than 1% in thrombolysis treatment rates. The study suggests that additional research is needed to understand why a gap persists and whether it continues to decrease.
A new study has found no link between recent cannabis use and an increased or decreased risk of ischemic stroke. Despite previous studies with conflicting results, researchers adjusted for various factors and found no association between marijuana use and stroke risk.
A blood test using neurofilament light chain may predict recovery time after concussion, especially for those with multiple concussions. High levels of the biomarker are associated with severe symptoms like post-traumatic stress disorder and depression years later.

Researchers found that people with dementia were more likely to eat these foods together, while those without dementia had a greater variety of healthier food options.
A new study shows that people with high blood pressure and reverse dipping may have small areas in the brain damaged from vascular disease, leading to memory problems. Those with high blood pressure and reverse dipping also had lower scores on a memory test, with average scores of about 33 compared to 40 for those without these conditi...
