Heart rate variability in obsessive compulsive disorder in comparison to healthy controls and as predictor of treatment response.

Objective: Obsessive compulsive disorder (OCD) has a large impact on the quality of life of patients. It often takes years to get the right diagnosis and to receive treatment. Therefore, biomarkers that could inform the diagnostic process and provide information on response or non-response for first line treatment approaches are urgently needed.

Altered EEG lagged coherence during rest in obsessive-compulsive disorder.

Objective: Functional magnetic resonance imaging (fMRI) studies found alterations of functional connectivity in obsessive compulsive disorder (OCD). However, there is little knowledge about region of interest (ROI) based electroencephalogram (EEG) connectivity, i.e.

EEG-vigilance regulation during the resting state in obsessive-compulsive disorder.

Objective: Obsessive compulsive disorder (OCD) has been associated with disturbed sleep-wake cycles and cortical hypermetabolism. However, it still remains unclear whether OCD is associated with a dysregulation of vigilance (i.e.
