Researchers say levels of microRNA in the blood may be a reliable new biomarker for diagnosing mild cognitive impairment and other forms of dementia.
People with genetic risks for Alzheimer’s disease may exhibit changes in brain structure and reduced performance in cognitive tests long before symptoms of the neurodegenerative disease become obvious.
PET study finds early accumulation of the tau protein in the brain is a better predictor of Alzheimer’s associated memory decline than amyloid plaque accumulation or cerebrospinal fluid biomarkers.
Higher glucose levels detected by a two-hour glucose test were an accurate predictor of poorer performance in tests of episodic memory ten years later.
Researchers have identified four cognitive profiles associated with menopause. Findings reveal women who experience stronger verbal learning and memory, in addition to better attention and executive function during menopause, are less likely to experie…
A newly developed brain model from cultivated stem cells allowed researchers to analyze molecular pathways of neurons in a dish. Researchers identified specific forms of amyloid beta and tau associated with cognitive decline and Alzheimer’s. They also …
Working until the age of 67 slows cognitive decline and appears to be neuroprotective against cognitive impairments and dementias.
A new test reveals an association between poor lifestyle choices and an increased risk of cognitive decline leading to dementia.
New studies have identified an association between daily high coffee consumption, brain shrinkage and an increased risk of dementia. However, researchers were unable to identify a causal relationship between caffeine consumption and dementia. The study…
Long-term circadian rhythm disruptions induce Alzheimer’s disease-like pathology in rats, which can be reversed by administering fluoxetine. Additionally, elevated levels of amyloid beta and circadian rhythm disruptions can trigger each other, leading…
Diet and exercise can influence hippocampal neurogenesis, researchers say. Poor nutrition and lack of exercise have detrimental effects on hippocampal neurogenesis, increasing the risk for dementia.
Study reaffirms findings that the gut microbiome may play a significant role in cognitive decline. Researchers found, in mice, a ketogenic diet, hypoxia, and the Bilophila wadsworthia bacteria impaired the hippocampus, leading to signs of cognitive dec…
Dipeptidyl peptidase-4 inhibitors, a class of drug that reduces blood sugar in type 2 diabetes, were associated with less amyloid accumulation in the brain and slower cognitive decline in patients.
The gut microbiome can be harnessed to reverse age-related brain deterioration and restore cognitive function, researchers report.
60% of 400 coronavirus survivors experienced lasting cognitive impairment, a new study reports. Cognitive problems were found in those who experienced mild-to-moderate COVID symptoms, as well as those who experienced more severe symptoms. One in three …
A diet that consists of at least half a serving of flavonoid-rich foods per day reduces the risk of cognitive decline in older adults by 20%.
A new study strengthens previous research linking dental health to dementia and cognitive decline. Researchers found tooth loss is a risk factor for cognitive decline and dementia, and with each tooth lost, the risk for cognitive impairment increases.
Performing written cognitive tests with a digital pen allowed researchers to identify differences between “thinking” and “writing” times that may be early biomarkers for cognitive and motor decline.
Nine out of ten older adults who reported symptoms of cognitive decline associated with dementia did not have a clinical diagnosis of neurodegeneration.
Higher levels of two cytokines were associated with slower cognitive decline in aging adults, a new study reports.
