The Central Executive Network CEN is responsible for working memory, attention, and goal-directed behavior. It helps you stay focused on tasks, make decisions, and solve problems. In ADHD, the CEN often shows reduced activation, which leads to difficulty maintaining attention, staying organized, and following through with tasks.
The DMN is active during restful, internally-directed activities like daydreaming, self-referential thinking, and remembering the past. In ADHD, the DMN can remain active even during tasks that require focus, leading to mind-wandering and trouble maintaining attention.
The Salience Network SN helps detect and filter relevant stimuli and switch between networks like the CEN and DMN. In ADHD, the SN might not properly coordinate the shift between the CEN (task-focused) and DMN (resting state), causing poor regulation of attention and cognitive control.
