  • Understanding the cognitive and neurological underpinnings of OCD is crucial for effective treatment.

Purpose of the Study:

  • To present a neuropsychological perspective on OCD.
  • To identify cognitive strengths and weaknesses associated with OCD.
  • To develop an integrated conceptual model of OCD based on neuropsychological and information processing theories.

Main Methods:

  • Review of neuroanatomic findings and theories on the neurologic basis of OCD.
  • Analysis of studies utilizing neuropsychological assessments.
  • Integration of cognitive-behavioral and information processing perspectives.

Main Results:

  • Evidence suggests frontal lobe and/or basal ganglia dysfunction in individuals with OCD.
  • Memory deficits are frequently observed in OCD patients.
  • Specific patterns of normal and abnormal information processing characterize OCD.

Conclusions:

  • Neuropsychological deficits, particularly in frontal lobe and basal ganglia function and memory, are key features of OCD.
  • An integrated model combining neuropsychological and information processing views offers a more complete understanding of OCD.
  • Further research can refine this model to improve therapeutic interventions for OCD.
