| |  Long-term benzodiazepine use in older adults disrupts sleep patterns, leading to lighter sleep and potential cognitive decline due to altered brain activity. | |
|
| |  In a landmark study of Hispanic and Latino adults, researchers at University of California San Diego School of Medicine have identified a link between self-reported cognitive decline and blood-based biomarkers, which could pave the way for a simple blood test to help diagnose Alzheimer's disease and related dementias. | |
|
| |  Exposure to high concentrations of air pollution may worsen Alzheimer's disease (AD) by accelerating the buildup of toxic proteins in the brain and speeding up cognitive decline. | |
|
| |  Individuals with an increased risk for dementia due to Alzheimer's disease can have impaired spatial orientation skills. | |
|
| |  Implementing changes to indoor environments, such as cooler bedrooms at night and increasing the amount of bright light during the day, could significantly improve sleep for people living with dementia, according to a study led by the University of Surrey. | |
