Study Links Anxiety to Decreased Activity in Brain's Cognitive Control Network
Advertisement
A recent study published in Psychophysiology highlighted the relationship between anxiety and brain function, particularly how anxiety impacts the cognitive control network. This research revealed that major anxiety disorders are linked to decreased activity in specific brain regions, which could serve as neural markers for anxiety symptoms.
Anxiety affects millions globally, ranging from mild to severe forms. While mild anxiety can heighten awareness, severe anxiety leads to debilitating disorders that impair daily functioning and often coexist with other mental health issues, like depression. Understanding the neural mechanisms behind anxiety is essential for developing effective treatments.
Previous research has shown inconsistent findings regarding anxiety’s impact on brain activity, especially in the frontal cortex.
In the study, researchers recruited 366 participants from Huazhong University of Science and Technology in Wuhan, China. Using the Hospital Anxiety and Depression Scale (HADS), participants were categorized into three groups based on anxiety levels: healthy controls, mild anxiety, and major anxiety.
