Randomized trial assesses cerebral glucose metabolism in panic disorder, indicating heightened brain activity in anxiety-related regions.

This study aims to evaluate cerebral glucose metabolism in individuals with panic disorder compared to healthy controls.
Used positron emission tomography to measure glucose uptake in the brain.
Compared 12 nonmedicated panic disorder patients with 22 healthy controls.
Analyzed specific brain regions associated with anxiety.
Panic disorder patients displayed significantly higher glucose uptake in the amygdala, hippocampus, and thalamus compared to controls.
Notable increases were also found in the midbrain, caudal pons, medulla, and cerebellum for patients.
Findings support the amygdala-centered fear network hypothesis in panic disorder.

Sakai et al. (2005) studied this question.
