Bilingualism has been linked to delayed symptoms of Alzheimer's disease once diagnosed with mild cognitive impairment, due to being more resilient in dealing with neurodegeneration.
A molecular switch that controls the immune system may be useful for reducing inflammation and age-related disease. The NLRP3 inflammasome can be switched off by the protein SIRT2 to lower inflammation.
The compound indole, found in cruciferous vegetables like kale, cabbage, broccoli, and cauliflower, fights inflammation in non-alcoholic fatty liver disease, which is 7-10 times more common with obesity.
Night shift workers have increased risk of developing sleep disorders and metabolic syndrome, which increase risk of heart disease, stroke, and type 2 diabetes, likely due to disrupted circadian rhythms.
Tau protein buildup in the brain has long been associated with Alzheimer's disease, but it has been unknown how tau becomes tangled and toxic. New techniques are mapping tau's development.
Suppressing a previously unknown protein, aggregatin, may be able to slow the progression of Alzheimer's disease (AD). Aggregatin accumulates within the plaque in brains of those with AD.
Combined results from 3 studies spanning 50 countries has found no link between moderate egg consumption (about one egg per day) and heart disease and cardiovascular-related mortality.
Stress activates the fight-or-flight response, which can cause permanent damage to stem cells in hair follicles that regenerate pigment. Stress leads to the premature depletion of the pigment reservoir.
Living less than 50 meters from a major road or less than 150 meters from a highway was linked to increased risk of dementia, Parkinson's, Alzheimer's, and MS, likely due to increased pollution.
Sun exposure regulates how fat cells produce energy; spending too much time indoors may disrupt this. Sunlight is required for normal energy metabolism, which could prevent metabolic syndrome.
Eating irregularly, especially on weekends ("eating jet lag") is linked to increased BMI. The highest increase was when meals were eaten 3.5-hours different on weekends versus weekdays.
High brain accumulation of aluminum found in those with familial Alzheimer's disease, which is linked to a genetic mutation, leads to high amyloid-beta plaques and an early and aggressive disease.
