Moderating effects of sex on the impact of diagnosis and amyloid positivity on verbal memory and hippocampal volume

Background Alzheimer’s disease (AD) impacts men and women differently, but the effect of sex on predementia stages is unclear. The objective of this study was to examine whether sex moderates the impact of florbetapir positron emission tomography (PET) amyloid positivity (A+) on verbal learning and memory performance and hippocampal volume (HV) in normal cognition (NC) and early ...

Preschool Externalizing Behavior Predicts Gender-Specific Variation in Adolescent Neural Structure

Dysfunction in the prefrontal cortex, amygdala, and hippocampus is believed to underlie the development of much psychopathology. However, to date only limited longitudinal data relate early behavior with neural structure later in life. Our objective was to examine the relationship of early life externalizing behavior with adolescent brain structure. We report here the first ...
