Delusional disorder,jealous type: how inclusive are the DSM,IV diagnostic criteria?

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 3 2008
Judith A. Easton
Abstract Delusional disorder,jealous type is a new diagnostic category in the Diagnostic and Statistical Manual for Disorders, Fourth Edition, Text Revision (DSM-IV-TR; American Psychiatric Association, 2000) in which delusions concerning a partner's infidelity must be present. Therefore, patients who experience a jealousy disorder, but do not experience delusions will not fit the diagnostic criteria. Using a database of 398 case histories of jealousy disorders reported in the literature from 1940,2002, we examined the percentage of these cases that met the diagnostic criteria for delusional disorder,jealous type. Only 4% of the cases met all diagnostic criteria. This is the first systematic comparison of the prevalence of these disorders. The results provide evidence that the diagnostic criteria are not inclusive, as most individuals suffering with a jealousy disorder were excluded from the diagnosis. © 2008 Wiley Periodicals, Inc.

Delusional disorder: Study from North India

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2007
SANDEEP GROVER md
Abstract, The aim of the present study was to study sociodemographic profile, clinical parameters including comorbidity, usefulness of antipsychotics especially atypicals, family history, and follow-up rates for delusional disorder. The records of all subjects who were seen in the Department of Psychiatry during a period of 10 years (i.e. 1994,2003) were reviewed. Eighty-eight subjects fulfilling the inclusion criteria were enrolled. The sample consisted predominantly of female subjects (55.7%), most of the total subjects were married and had favorable social functioning. The most common delusion was persecutory (54.5%), followed by delusion of reference (46.6%). The majority of the subjects had a comorbid psychiatric disorder. Education was negatively correlated with age at onset and positively correlated with the number of delusions. Age at onset was negatively correlated with total number of delusions. The sociodemographic profile of delusional disorder is consistent across various cultures, has high comorbidity and, when treated appropriately, responds to various antipsychotic agents. [source]

Hyperperfusion in primary somatosensory region related to somatic hallucination in the elderly

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 4 2010
Kiyotaka Nemoto MD
Aim:, The purpose of the present study was to investigate the regional cerebral blood flow (rCBF) of patients with delusional disorder, somatic type (DDST) exhibiting somatic hallucination. Methods:, Five patients diagnosed with DDST, as well as 20 control subjects, were examined. All subjects underwent technetium-99m ethyl cysteinate dimer brain perfusion single-photon emission computed tomography. Statistical analysis was performed with SPM5, using a two-sample t -test model to test the regional population effect on rCBF. Results:, Patients with DDST had a significant increase in perfusion in the left post-central gyrus and the right paracentral lobule, both of which are involved in somatic sensory processing. Conclusion:, Somatic hallucination might be associated with increased perfusion in the primary somatosensory regions. [source]

Genetics and delusional disorder

BEHAVIORAL SCIENCES & THE LAW, Issue 3 2006
Alastair G. Cardno M.B., M.R.C.Psych., Ph.D.
This article gives an overview of genetic research approaches and their application to delusional disorder. Most studies have been based on small samples and have had other methodological limitations, so it is not clear whether there is a genetic contribution to the aetiology of delusional disorder. It is unlikely that delusional disorder is strongly related genetically to affective disorder or schizophrenia, but more subtle relationships cannot be ruled out. The rarity of multiply affected families prohibits linkage studies and, to date, molecular genetic investigations have been mainly limited to small association studies of dopamine receptor polymorphisms. A range of considerably larger, epidemiologically rigorous studies is required, but the uncommonness and other features of the disorder put strong limitations on the prospects for ascertaining adequate samples.
