A new study suggests carriers of a genetic mutation in the serotonin 2B receptor may be protected from obesity and insulin resistance.
Obesity risk in teens appears to be associated with stronger connectivity within and between regions of the brain implicated in determining the salience of stimuli. This may have implications for reward processing. Researchers report executive control efforts in the brain decrease when salience and reward-processing regions are engaged in teens with obesity.
Researchers say the combination of low muscle mass and strength in the context of high fat mass, could be a predictor of cognitive function in older adults. Sarcopenic obesity could be used to predict risk factors for developing dementia, the study reports.
Researchers have identified nine risk factors during different stages in life that may increase a person's likelihood of developing dementia. At least 35% of dementia cases, researchers say, may be directly linked to these risk factors. By taking steps to reduce risks and by improving education, it is estimated that the incidence of dementia can be reduced by as much as 20%.
Children with higher cardiorespiratory and muscular fitness and a lower waist-to-hip ratio had higher scores in cognitive tests for attention and processing speed during middle age.
While there is an association between obesity during midlife and an increased risk of Alzheimer's disease, researchers say the link doesn't necessarily extend into later life. A new study revealed higher genetic risk for Alzheimer's and lower BMI, especially in older men, was linked to an increased risk of Alzheimer's disease and predicted the disease progression.
A new study reveals adults with ADHD have an increased risk of developing nervous system, respiratory, musculoskeletal, and metabolic diseases. ADHD was also associated with a slightly increased risk of Parkinson's disease, dementia, and cardiovascular disease.
Researchers focus on gray matter volume on three areas of the brain. Findings suggest cardiovascular risk factors such as obesity and diabetes could be early indicators for Alzheimer's disease.
Soybean oil, the most consumed cooking oil in the US, has been linked to neurological and metabolic alterations in mice. Soybean oil-fed mice showed decreased levels of oxytocin in the hypothalamus.
