The Role of Neurophysiological Biomarkers in Obsessive-Compulsive Disorder

Area of Science:

• Neuroscience
• Psychiatry
• Biomarker Research

Background:

• Obsessive-compulsive disorder (OCD) is a severe mental health condition with frequent treatment resistance.
• Identifying reliable biomarkers for OCD is crucial for predicting patient outcomes and treatment efficacy.

Purpose of the Study:

• To review the literature on heart rate variability (HRV) and electroencephalography (EEG) as potential physiological biomarkers for OCD.
• To assess the current evidence for HRV and EEG in predicting treatment response and prognosis in OCD patients.

Main Methods:

• A narrative literature review was conducted.
• Key studies investigating HRV and EEG in relation to OCD were analyzed.

Main Results:

• Decreased HRV correlates with increased OCD symptom severity.
• EEG findings show potential in predicting response to pharmacotherapy for OCD.
• Current evidence is limited by a small number of studies and inconsistent results.

Conclusions:

• HRV and EEG show potential as biomarkers for OCD, particularly in predicting pharmacotherapy response.
• Further research is necessary to establish the clinical validity and utility of these physiological measures in managing OCD.
• Larger, more consistent studies are required to confirm the role of HRV and EEG in clinical practice for OCD.
