- Cognitive and Salience Network Connectivity Changes following a Single Season of Repetitive Head Impact Exposure in High School Football
High school football players and controls underwent cognitive battery testing. The study found that football players had subtle cognitive decrements. MRI revealed altered brain connectivity, with decreased dorsal anterior cingulate cortex interhemispheric connectivity and within-salience network connectivity, which correlated with poorer total symptoms and verbal memory performance, respectively.
- Territory-Related Functional Connectivity Changes Associated with Verbal Memory Decline in Patients with Unilateral Asymptomatic Internal Carotid Stenosis
Fifteen healthy controls, 22 patients with left asymptomatic ICS, and 33 patients with right asymptomatic ICS underwent fMRI, Mini-Mental State Examination, Digit Span Test, and Verbal Learning Tests. Patients with asymptomatic ICS had significant impairment in delayed recall of verbal memory. Patients with left and right asymptomatic ICS showed different patterns of FC alterations in both anterior and posterior circulation territories.
