Background: Although structural and functional abnormalities have been found in patients with schizophrenia, very few studies have investigated neuroimaging features in delusional disorder patients. We conducted a review of the literature to assess the evidence for specific neuroimaging changes in delusional disorder on brain structures and

The article reviews the historical background and symptoms of body dysmorphic disorder (BDD) and olfactory reference disorder, and describes the proposals of the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders related to these categories. This paper examines the possible classification of BDD symptoms in ICD-10. Four different possible diagnoses are ...

OBJECTIVE Clinical, familial, and, more recently, genetic linkage studies suggest that overlapping genetic susceptibility might contribute to both schizophrenia and bipolar disorder. To identify a potential psychotic dimension common to families of both bipolar and schizophrenia probands, the authors tested if delusional proneness was observed among first-degree relatives of bipolar and schizop...

OBJECTIVE Although body dysmorphic disorder often responds to serotonin reuptake inhibitors (SRIs), most patients do not respond or respond only partially. However, placebo-controlled studies of augmentation of SRIs have not been done. Furthermore, although 40%-50% of patients are delusional, studies of antipsychotic medications have not been done. METHOD Twenty-eight patients with body dysmo...

The body of knowledge on delusional parasites is incriminates “delusional patients” as having imaginary external and internal symptoms that feel like parasite movements, dismisses them as psychiatric cases, and confuses cause with effect. We are critical of these arguments and believe that the symptoms of crawling and pin-pricking are genuine; just misinterpreted as parasite movements. Based on...

BACKGROUND Delusional disorder has been the subject of very little investigation using brain imaging. AIMS To examine potential structural and/or functional brain abnormalities in this disorder. METHOD We used structural imaging (voxel-based morphometry, VBM) and functional imaging (during performance of the n-back task and whole-brain resting connectivity analysis) to examine 22 patients m...
