Evaluations of hemodynamic changes during neuropsychological test batteries using near-infrared spectroscopy in patients with obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a relatively common, and frequently debilitating, neuropsychiatric disorder that affects approximately 2% of the population (Ruscio et al., 2010). It is characterized by repetitive thoughts (obsessions) and behaviors (compulsions) that are intrusive and unwanted. The obsessions and compulsions are time-consuming or cause clinically significant distress or impairment in social, occupational or other important areas of functioning (DSM-5). Individuals with OCD often have a variety of psychopathology including autistic traits (Cadman et al., 2015; Krebs and Heyman, 2015; Mito et al., 2014; Ruzzano et al., 2015) or psychiatric comorbid disorders such as major depression or any anxiety disorder (LaSalle et al., 2004; Ruscio et al., 2010; Salin-Pascual and Basanez-Villa, 2003; Valero Aguayo et al., 2014).
