Volume 2 Issue 7, July 2024

Default-mode network and dementia

Alzheimer’s disease and dementia are associated with changes in the default-mode network (DMN), the distributed set of regions that are active when an individual is not focused on an external task or stimuli. In this issue, Ereira et al. demonstrate that altered DMN connectivity can be used to identify future dementia incidence at the individual level. The cover of the July issue alludes to the possibility of using brain activation patterns in the DMN to predict dementia and its potential for early detection and intervention.

Research Briefings

  • Mood dysfunction is more common in people with brain tumors than in those with other tumor types, but the reasons for this association are unclear. Using various methods for lesion–symptom mapping, we identified brain locations in patients with diffuse glioma that are related to severe depressive symptoms or an absence of depressive symptoms.
