Cognitive flexibility and response inhibition in patients with Obsessive-Compulsive Disorder and Generalized Anxiety Disorder

摘要

Background/ObjectiveThe main aim of this study was to analyze differences in inhibition and cognitive flexibility, taking into account some variables that may influence results (non verbal reasoning, depression, anxiety, intolerance of uncertainty, comorbidity, medication consumption).MethodThe participants were 95 adults aged 17-61 years old (M=33.48,SD=11.13), primary (most severe) Generalized Anxiety Disorder or Obsessive-Compulsive Disorder and a healthy control group. Neuropsychological neasures were completed using computerized Wisconsin Card Sorting Test, Stroop Color Word Test and Go/NoGo Task.ResultsClinical groups presented worse results in cognitive flexibility to the control group. The obsessive-compulsive group showed worse scores in flexibility than the generalized anxiety group, once non-verbal reasoning and tolerance to uncertainty were controlled. Comorbidity and medication use did not affect results in the obsessive compulsive group but did however influence the generalized anxiety group.ConclusionsCognitive flexibility could be included treatment in the treatment of obsessive-compulsive disorder and generalized anxiety disorder.
