Introduction: Delusional disorder shares some clinical characteristics of OCD and hypochondriasis. Delusions compared to obsessions in the OCD and compared to bodily preoccupations in the hypochondriasis are more established beliefs.
Aim: To measure pituitary volumes in patients with delusional disorder and hypothesized that volumes would be reduced in those patients by a mechanism that we could not account for before for patients with OCD and hypochondriasis.
Objectives: Moving from the point that there might be an association between the neuroanatomy of obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder, we decided to examine the volumes of hippocampus and amygdala of patients with obsessive-compulsive personality disorder, which was previously evaluated in OCD patients by us.
Methods: Volumes of the hippocampus, and amygdala were measured by magnetic resonance imaging (MRI) in patients with obsessive-compulsive personality disorder and healthy control subjects. Manual tracing was used.
Objectives: Obsessive compulsive personality disorder (OCPD) is currently thought to bear a close relationship with obsessive-compulsive disorder (OCD), and other compulsive disorders such as eating disorder and autistic spectrum disorder, as well as with the personality disorders, focusing on some important dimensions like phenomenology, heritability, environmental risk factors, comorbidity, course of illness, neurocognitive endophenotypes, and treatment response. In the present study, when we have taken into consideration the knowledge aforementioned, we aimed to examine OFC and thalamus volumes in patients with OCPD.
Methods: We comparatively measured orbito-frontal cortex (OFC) and thalamus volumes of patients with OCPD and healthy control subjects.
