According to a new study, women with the APOEe4 allele, a genetic variant closely tied to Alzheimer's disease, face sharper weight loss after the age of 70 than those without the gene, whether they go on to develop dementia or not.
A new study reports on a link between age, body mass index and brain integrity in psychosis. Researchers discovered higher age, BMI and severity of psychotic symptoms were negatively associated with cortical thickness and brain activity when patients were asked to perform cognitive tasks.
A new study sheds light on the roles both genetics and neuroanatomy play in obesity. Researchers report those with higher BMI had reduced cognitive flexibility, reduced ability to delay gratification and worse verbal memory. Additionally, those with increased BMI have increased amygdala and left prefrontal cortex volume.
