Electroencephalogram Changes After Virtual Reality-Based Cognitive Behavioral Therapy for Panic Disorder.
Article in Journal of Korean medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCognitive behavioral therapy (CBT) for panic disorder involves training to cope with anxiety and panic attacks effectively. Recently, CBT, when integrated with anxiety-inducing virtual reality (VR) scenarios, has been utilized to treat panic disorder. This study aimed to investigate the neurophysiological impacts of VR-enhanced CBT in the treatment of panic disorder. MATERIALS: Nineteen patients (6 men and 13 women; average age: 36.0 ± 11.7 years) diagnosed with panic disorder participated in four sessions of VR-based CBT. The VR program included educational elements focusing on abdominal breathing and muscle relaxation and training components that utilized relaxation techniques during exposure to a VR environment. Psychometric assessments and electroencephalogram (EEG) readings were collected before and after the CBT sessions. The EEG studies were performed under two conditions: a resting state and while engaging in a visual working memory task.
resultsThe Panic Disorder Severity Scale for panic symptoms improved following VR-based CBT. Although error rates in the Stroop test did not change before and after CBT, reaction times improved. Additionally, several EEG indicators exhibited differences pre- and post-CBT, with increased left frontal beta and parietal theta power observed during a visual working memory task.
conclusionThis study indicated that VR-based CBT may alleviate panic symptoms and enhance cognitive functions, particularly executive control. Additionally, EEG results suggested that VR-based CBT could strengthen brain activity associated with working memory performance.
