Summary
Individuals with anxiety disorders show impaired inhibitory control, linked to reduced prefrontal cortex activation. This study highlights neural correlates of these deficits, suggesting potential therapeutic targets for enhancing cognitive abilities in anxiety.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Clinical Psychology
Background:
- Anxiety disorders are associated with cognitive control deficits, potentially due to prefrontal network dysfunction.
- Neural mechanisms underlying these impairments in anxiety remain unclear.
- This study investigates inhibitory ability and its neural correlates in anxiety.
Purpose of the Study:
- To compare inhibitory control between individuals with anxiety and healthy controls.
- To explore the neural correlates of anxiety-related inhibitory deficits.
- To identify potential therapeutic targets for cognitive enhancement in anxiety disorders.
Main Methods:
- 118 participants (59 anxiety, 59 controls) were assessed.
- Inhibitory ability was measured using the Stroop task and verbal fluency task (VFT).
- Functional near-infrared spectroscopy (fNIRS) measured prefrontal cortex (PFC) activation.
Main Results:
- Anxiety group showed reduced PFC activation, slower/less accurate inhibitory control, and poorer VFT performance.
- Anxiety severity correlated negatively with inhibitory ability and PFC activation.
- Dorsolateral PFC activation mediated the link between anxiety and inhibitory performance.
Conclusions:
- Anxiety disorders are characterized by specific neural patterns affecting inhibitory control.
- Findings identify neural correlates of anxiety-related inhibitory deficits.
- Results suggest potential intervention targets for improving cognitive function in anxiety.
