This review explores the neurobiology of obsessive-compulsive disorder (OCD), highlighting brain imaging and neurochemical findings. Research suggests a functional imbalance in the orbitofrontal-basal ganglia-thalamus circuit contributes to OCD.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Neurobiology

Context:

  • Obsessive-compulsive disorder (OCD) is a debilitating mental health condition.
  • Understanding the neurobiological underpinnings of OCD is crucial for developing effective treatments.

Purpose:

  • To review current biological research on obsessive-compulsive disorder (OCD).
  • To present findings from functional brain imaging and neurochemical studies.
  • To discuss a neurobiological model of OCD.

Summary:

  • Functional brain imaging studies reveal altered brain activity during symptom provocation and treatment in individuals with OCD.
  • Neurochemical studies focus on the role of the serotonergic system in OCD.
  • A neurobiological model suggests a functional imbalance within the orbitofrontal-basal ganglia-thalamus circuit in OCD.
