Responses to emotion-inducing stimuli were examined in 27, 3- to 6-year-old children, who were prenatally exposed to cocaine, and 27 unexposed controls. Children were monitored for EEG activity and their affect during an infant crying, simulated maternal distress, and a mildly frustrating task. Multivariate analyses indicated that the cocaine-exposed children had greater right frontal EEG asymmetry, showed fewer empathic reactions to a crying infant as well as to their own mothers, and they were less proficient in completing a cooperative task. These findings highlight the need for continued longitudinal research on the effects of early drug exposure for later socioemotional development.

Previous research has revealed that the insula, pallidum, thalamus, hippocampus, middle frontal gyrus, and supplementary motor area are activated during odor memory and that the performance of olfactory working memory is affected by the verbalization of odors. However, the neural mechanisms underlying olfactory working memory and the role of verbalization in olfactory working memory are not fully understood. Twenty-nine participants were enrolled in a study to complete olfactory and visual n-back tasks using high- and low-verbalizability stimuli while undergoing fMRI imaging.

Duchenne gait, characterized by an ipsilateral trunk lean towards the affected stance limb, compensates for weak hip abductor muscles, notably the gluteus medius (GM). This study aims to investigate how electromyographic (EMG) cluster analysis of GM contributes to a better understanding of Duchenne gait in patients with cerebral palsy (CP). We analyzed retrospective gait data from 845 patients with CP and 65 typically developed individuals.

Importance: The extent to which neuroanatomical variability associated with early substance involvement, which is associated with subsequent risk for substance use disorder development, reflects preexisting risk and/or consequences of substance exposure remains poorly understood.
Objective: To examine neuroanatomical features associated with early substance use initiation and to what extent associations may reflect preexisting vulnerability.
Design, Setting, And Participants: Cohort study using data from baseline through 3-year follow-up assessments of the ongoing longitudinal Adolescent Brain Cognitive Development Study.

Background: Type 2 diabetes (T2D) is a prevalent health condition associated with cognitive impairment and dementia. T2D induces adverse effects not only on the pancreas but also on the liver, kidneys, muscles, fat cells, and, notably, the brain. Both T2D and Alzheimer's disease (AD) exhibit associations with neurodegeneration, yet the extent of their shared patterns of brain atrophy remains poorly understood, potentially indicating common pathways.

However, while PVS is also prevalent amongst Vascular Dementia (VD), the pathological distinctions between regional PVS in AD- and VD-driven cohorts remain largely unknown. Through a mixed dementia cohort, we examined these pathology-driven localization patterns via automated PVS segmentations from T2-weighted MRI.
