However, some CNVs have been linked with both disorders. ResultsChronic cannabinoid treatment induces behaviours relevant to positive, negative and cognitive symptoms of schizophrenia. The same abnormalities were again seen in the same patients. This volume gives the reader an inside look at how psychotic phenomena are represented in the current diagnostic system and how DSM-V might better address the needs of patients with such disorders. In comparison to most developed countries, early interventions programs are only little developed in France. ∆9-tetrahydrocannabinol, CP55,940 and WIN55,212-2]. An fMRI word-encoding study showing connectivity differences between patients with schizophrenia and healthy controls in left superior temporal gyrus (STG) to dorsolateral prefrontal cortex (DLPFC) and to ventrolateral prefrontal cortex (VLPFC). (from Davatzikos et al 12 ). Yet little is known about the routine practices of youth psychiatrists regarding psychosis risk management. Psychiatry Res 2001 ; 108 : 1 – 15 . Method Studies were screened and coded by two independent reviewers. This notion has led to the claim that schizophrenia is not a valid concept for biological research and should be "deconstructed", ... Congruent with those ideas, schizophrenia patients usually exhibit high interindividual variance with regard to, e.g., brain structure changes, reflecting a higher heterogeneity amongst the patients than amongst healthy controls. Results: Eleven studies were eligible for this review; one was a behavior genetics study, two were molecular genetics studies, two were neurological studies, and six studies examined physiological factors such as skin conductance and salivary cortisol. Chronic cannabinoids also cause region- and subtype-specific changes to receptor systems (e.g. Raquel E Gur Department of Psychiatry, University of Pennsylvania 10 Gates, 3400 Spruce Philadelphia, PA 19104, USA. There are consistently replicated associations of psychotic symptoms and cognitive impairment in both structural and functional imaging in schizophrenia but not, as yet, in bipolar disorder. Various experimental data were used to validate the motion detection algorithm; on the whole, the proposed method was tested with approximately 100 test cases. Numerous studies shown that structural hippocampal alterations are present in subjects at high risk of developing psychosis or schizophrenia. 2013). Gur RE, Keshavan MS, Lawrie SM. Schizophr Bull 2007 Gur 921 31 - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Periventricular hyperintensities were more common in bipolar I patients (62%) than in bipolar II patients (38%) and normal comparison subjects (30%). Plasma BNP concentrations in EF < 50% patients were greater than those in EF > or = 50% patients (335.2 +/- 60.2 vs. 101.2 +/- 41.3 pg/ml, p < 0.01, both n = 17). If patient motion is detected, the scanning procedure is stopped. The PPDA shows promising results. We used coordinate-based meta-analyses, namely the anatomical likelihood estimation (ALE) algorithm on 30 schizophrenia-related imaging genetics studies, representing 44 single-nucleotide polymorphisms at 26 gene loci investigated in 4682 subjects. Interestingly, functional imaging studies in humans have found abnormal activation in the LPFC of patients with schizophrenia, Quantitative SPECT brain imaging was performed in five normal subjects and in six ambulatory patients with Alzheimer's disease before the initiation of treatment with tetrahydroaminoacridine (THA) and lecithin. Aim To test whether these findings provide trait-markers for schizophrenia. Thus, treated patients showed a pronounced increase in basal ganglia volumes. ... Deconstructing Psychosis With Human Brain Imaging. Progress in the delivery of better outcomes for schizophrenia has halted. The authors sought to evaluate the presence of signal ''hyperintensities'' in both bipolar I and II subjects and systematically review the existing literature. To make a comment you must login or register. The formation of a stress memory will be explored. The presence and location of signal hyperintensities in three brain regions (periventricular white matter, subcortical gray matter, and deep white matter) were evaluated. Gaining an understanding of the neurobiology involved in schizophrenia may facilitate the delivery of better clinical outcomes. PubMed. Psychological testing in each patient demonstrated the presence of low to borderline intellectual functioning coupled with neuropsychological deficits in different psychiatric domains. The book … The revision process of the international psychiatric classification systems has started and is expected to result in new versions of the International Classification of Disorders (then ICD-11) and the Diagnostic and Statistical Manual (then DSM-V) in approximately 2014 and 2012, respectively. Uptake per pixel in 28 regions of. The number of medical diseases that can present with psychotic symptoms (ie, delusions, hallucinations) is legion. The evidence base consists of hundreds of studies of patients with schizophrenia and fewer on bipolar disorder but rarely providing direct comparisons between the disorders or integration across methods.

This cross-sectional study describes 3 case-studies of adolescent subjects, ages 16–17, admitted at the child and adolescent inpatient psychiatric unit in lieu of first psychotic episode. The Paradox of Copy Number Variants in ASD and Schizophrenia: False Facts or False Hypotheses? Plasma BNP levels were also compared between higher and lower 1/3FF patients matched for LVEF. For instance, psychosis, mood disturbance, persistently low mood, anxiety or a delayed reaction in the case of post-traumatic stress disorder. The use of schizophrenia as a synonym for psychosis enlightens participants' contemporary representation of psychosis as an equivalent of schizophrenia. Using coordinate-based meta-analyses to explore structural imaging genetics, Developing a Neuropsychiatric Functional Brain Imaging Test. Do cognitive and neuropsychological functioning deficits coincide with hippocampal alteration during first-psychotic episode? Participants in our study were students that completed the ESQUIZO-Q-A and were set in two groups, high schizotypy (HS) and low schizotypy (LS). This review synthesizes our current knowledge on the neurobiology of psychosis from an array of in vivo brain-imaging studies. Some studies have proposed a somewhat similar mechanism for the origin of 'hallucinatory representations' in neural network models 45 . We aim to determine whether cognitive and neuropsychological functioning deficits precede or follow hippocampal alterations during early onset psychosis. These consistent changes, affect the brain's volume and tissue (white and grey matter), in both the hippocampal and pre-frontal brain regions. neuroimaging/schizophrenia/psychosis/brain. Illustration of DTI measures showing fractional anisotropy (a, b) and with delineation of specific ROIs corresponding white matter tracts can be visualized showing front-back (c) and left-right callosal connectivity (d) (courtesy of R. Verma, University of Pennsylvania). Amygdala pathology in psychosis of epilepsy: a magnetic resonance imaging study in patients with temporal lobe epilepsy . To test whether analyses based on biological information would improve the convergence of results, gene ontology (GO) terms were used to group the findings from the published studies. Anticipating a psychosis onset remains a highly uncertain task for psychiatrists. These symptoms are also found commonly in the other categories of psychosis described in DSM-IV. Advances in neuroimaging technologies have created both opportunities and challenges in the study of psychosis. Deconstructing Psychosis Conference February 2006: The Validity of Schizophrenia and Alternative Approaches to the Classification of Psychosis. This volume gives the reader an inside look at how psychotic phenomena are represented in the current diagnostic system and how DSM-V might better address the needs of patients with such disorders. The primate lateral prefrontal cortex (LPFC) encodes visual stimulus features while they are perceived and while they are maintained in working memory. We distinguish between adolescent and adult cannabinoid treatments, to determine if adolescence is a period of susceptibility to schizophrenia-relevant molecular changes. A series of recent papers has demonstrated “mirror extreme” variation in measures of brain size, between individuals with deletions compared to duplications, for copy number variation loci. Deconstructing Psychosis: Refining the Research Agenda for DSM-V provides an all-important summary of the latest research about the diagnosis and pathophysiology of psychosis. Conclusions: Having bipolar I disorder significantly increases the chance of having white matter changes in the brain. The new prediction of projection data algorithm (PPDA) detects most motions-such as those of the head, legs, and hands-using comparison of the predicted and measured frame data. Each subject was scanned twice without movement in a supine position, and 444 and 555 MBq 99mTc-HMPAO were separately injected intravenously during the, The aim of this study was to evaluate the left ventricular (LV) functional parameters calculated using quantitative electrocardiography (ECG)-gated myocardial perfusion single photon emission computed tomography (QGS). The purpose of this study was to examine the 1H NMR profile of major neural cell types. There is also compelling evidence that brain structure may predict or moderate treatment outcomes. Nevertheless, they provided their young patients with multiple months follow up without disclosing any risk category. Deconstructing Psychosis With Human Brain Imaging Raquel E. Gur, 1, 2 Matcheri S. Keshavan, 3 and Stephen M. Lawrie 4 2 Department of Psychiatry, University of Pennsylvania, Philadelphia, Pennsylvania, USA 3 Department of Psychiatry and Behavioral Neurosciences, Wayne State … Marked abnormalities of 1H NMR brain spectra have been reported in patients with neurological disorders, but their neurochemical implications may be difficult to appreciate because NMR data are obtained from heterogeneous tissue regions composed of several cell populations. It deserves to be emphasized that we only retrieved significant results, when we pooled over studies analyzing gene × diagnosis interactions, while other groupings, e.g., based on biological information about the implicated genes (GO terms) did not yield any significant convergence of findings. To the Editor.— Although these and other potential pit-falls could exist if tests are not applied carefully, a number of potential advantages exist that advanced neuroimaging technologies have to offer in order to assist with decision making. Over the last twenty years, predicting psychosis has become a priority of both research and policies. However, cases of young patients presenting unclear symptoms that might be a beginning psychosis or might as well reflect some adolescent unease are commonplace in psychiatry. Deconstructing psychosis with human brain imaging. The item Deconstructing psychosis : refining the research agenda for DSM-V, edited by Carol A. Tamminga ... [et al. Deconstructing Psychosis: Refining the Research Agenda for DSM-V provides an all-important summary of the latest research about the diagnosis and pathophysiology of psychosis. The finding that meningeal cells have an alanine:creatine ratio three to four times higher than astrocytes, neurons, or oligodendrocytes is in agreement with observations that meningiomas express a higher alanine:creatine ratio than gliomas. However, it remains unclear whether perceived and memorized features are encoded by the same or different neurons and population activity patterns. Our most unexpected finding was a large amount of N-acetyl-aspartate (NAA) in O-2A progenitors. This heterogeneity in the patient group has been explained due to different patterns of genetic lesions in individual patients that, in turn, lead to different endophenotypes, which are phenotypically, however, all assumed under the diagnosis of schizophrenia. Importantly, all participants showed better recognition of emotional facial expressions when they were trained with differential outcomes. A subsequent cluster analysis identified representative, non-redundant subsets of semantically similar terms that aided a further interpretation. And imaging tools, like PET scans and MRIs, show that people who have schizophrenia have less “gray matter” -- the part of the brain that contains nerve cells -- over time. A Schematic Representation of the Central Role of Neuroimaging Intersecting Between Basic Science and Clinical Applications. Imaging data were acquired with a single-head SPECT camera and a high-resolution collimator after the intravenous injection of 5 mCi of (p,5n) I-123 IMP. Deconstructing Psychosis With Human Brain Imaging Deconstructing Psychosis With Human Brain Imaging Gur, Raquel E.; Keshavan, Matcheri S.; Lawrie, Stephen M. 2007-06-04 00:00:00 This review synthesizes our current knowledge on the neurobiology of psychosis from an array of in vivo brain-imaging studies. SPECT imaging was repeated in the six patients after initial titration to peak therapy with oral THA (75 to 200mg per day). Deconstructing psychosis with human brain imaging. following 2 conditions: resting state with an empty bladder and urine-withholding state with a full bladder. Discussion: Findings suggest that social work as a Method: Magnetic resonance images of the brain were obtained prospectively for 29 patients with bipolar I disorder, 26 patients with bipolar II disorder, and 20 normal comparison subjects. Research output: Contribution to journal › Article. By Raquel E. Gur, Matcheri S. Keshavan and Stephen M. Lawrie. By the QGS data with 16 framing data acquisition using technetium (Tc)-99m methoxyisobutylisonitrile (MIBI) perfusion, we calculated the following parameters: LV end-diastolic volume (EDV), end-systolic volume (ESV), ejection fraction (EF), peak filling rate (PFR), filling rate during the first third of the filling time (1/3FR) and first third filling fraction (1/3FF). Methods: Systematic review procedures were employed to locate studies that included biological variables (e.g., genetic or physiological factors) related to behavior and were published in a social work journal between 2000 and 2015. A region of DLPFC shows greater connectivity with STG in controls, while a region in VLPFC shows greater connectivity with STG in patients (from Wolf et al 99 ). Our case report adds to the armamentarium of literature signifying that radiologically detectable alterations of the hippocampus may occur either concomitantly or closely following the development of early cognitive deficits in patients with FPE. It is likely that a number of these mechanisms are simultaneously impacted by chronic cannabinoids, thereby increasing schizophrenia risk in individuals who use cannabis. For example, brain structural alterations were found to predict antipsychotic drug treatment outcomes, ... duplications). Access scientific knowledge from anywhere. Schizophr Bull 2007 Gur 921 31 The degree of LV systolic and diastolic dysfunctions evaluated by QGS correlated with that by UCG or BNP. The aim of this study was to identify the brain areas that control urinary continence in healthy men by 99mTc-hexamethylpropyleneamine oxime (99mTc-HMPAO) SPECT. "Deconstructing Psychosis: Refining the Research Agenda for DSM-V" provides an all-important summary of the latest research about the diagnosis and pathophysiology of psychosis. Plasma BNP concentrations in 1/3FF < 35% patients were significantly greater than those in 1/3FF > or = 35% patients (312.9 +/- 62.5 vs. 120.5 +/- 32.8 pg/ml, p < 0.05, both n = 14). The purity of the cultured cells was > 95% with all the cell lineages, except for neurons (approximately 90%). While previous research failed to identify structural brain abnormalities in human cannabis users, more recent studies using high resolution imaging techniques combined with more robust delineations of specifi c brain regions in very heavy cannabis users have revealed evidence of dose-related alterations in regions implicated in schizophrenia. Replicated findings in schizophrenia include reduced whole-brain and hippocampal volume as potential vulnerability markers, with further progression at onset; reduced N-acetyl aspartate concentrations in hippocampus and prefrontal cortex; striatal dopamine D(2) receptors upregulation; and alteration in the relation between frontal and temporal activation. Research paper by Raquel E RE Gur, Matcheri S MS Keshavan, Stephen M SM Lawrie Indexed on: 06 Jun '07 Published on: 06 Jun '07 Published in: Schizophrenia bulletin We did not find any significant results for the main contrast. One possibility is that the paradoxical CNV data represents, to some degree, false positive diagnoses. Make a Comment. Our results indicate that a functionally diverse population of LPFC neurons provides a substrate for discriminating between perceptual and mnemonic representations of visual features. Deconstructing psychosis with human brain imaging. We regard this approach as a new option to systematically explore the richness of the literature in imaging genetics. Schizotypy is defined as a combination of traits qualitatively similar to those found in schizophrenia, though in a minor severity, that can be found in the nonclinical population. All rights reserved. The Grounded Theory is an agreed-upon qualitative method in social science field that links subjective experiences (individual narratives) to social processes (professional norms and mental health policies). 33 Recent studies using psychopathological dimensions ... and depends on a model where psychological behavior and brain structure constitute a … Download Deconstructing Psychosis PDF eBook Deconstructing Psychosis DECONSTRUCTING PSYCHOSIS EBOOK AUTHOR BY STEPHEN D... 0 downloads 65 Views 27KB Size DOWNLOAD .PDF Schizophrenia-relevant behavioural consequences of chronic cannabinoid treatment are first briefly summarised, followed by a detailed account of changes to several receptor systems [e.g. This review revealed a metabolic disorder that produces an adaptation to chronic nutrient or hypoxic stress. We find neurons with a wide variety of combinations of coding strength for perceived and memorized directions: some neurons encode both to similar degrees while others preferentially or exclusively encode either one. The results of one randomised control trial testing a psychological rehabilitation programme aimed at information processing strategies showed improvements in cognition post-treatment. By UCG, we measured mitral early to atrial (E/A) wave velocity ratio and pulmonary venous inflow systolic/diastolic (S/D) ratio as diastolic functional parameters. The latter finding appears as contradictory to the prevalent notion in the field that research approaches based on biological (patho-)mechanisms might help to reduce the heterogeneity of imaging findings compared to a purely symptom-based definition of schizophrenia (Tandon et al. NEUROSCIENCE > Large-scale family studies and new drug probes focus on cognitive deficits that may lie at the heart of the disease Generations of researchers have struggled to get at the core of schizophrenia, but with little success: No one knows the cause of this dread disease, many efforts to unravel the genetics behind it have ended in frustration, and no cure is in sight. In this research, we further explore this issue and we investigate, for the first time, whether the differential outcomes procedure (DOP) may improve the recognition of emotional facial expressions.

Perfusion was decreased greater than 2 SD below the mean in the posterior parietal cortex of 5/6 patients, in the temporal cortex of 3/6 patients, and in the frontal cortex of 2/6 patients with Alzheimer's disease. The images were analyzed by statistical image analysis software and displayed on Z-score images at a significance threshold of P < 0.05 with correction for multiple comparisons. Conclusions The spatial patterns are similar, except that treated patients display generally stronger effect sizes. Join ResearchGate to find the people and research you need to help your work. Instead, patients failed to deactivate the precuneus relative to other groups. Deconstructing Psychosis: Refining the Research Agenda for DSM-V provides an all-important summary of the latest research about the diagnosis and pathophysiology of psychosis. An evidence base will be presented to support rationale for relabeling psychiatric disorders as a stress memory with prominent symptoms. discipline is not contributing new knowledge to advance the ‘‘bio’’ component of the biopsychosocial framework. concentrations. In addition to LV systolic parameters, diastolic parameters were compared with those by ultrasound echocardiography (UCG) and also with plasma B-type natriuretic peptide (BNP). Deconstructing Psychosis by Carol A. Tamminga, 9780890426531, available at Book Depository with free delivery worldwide. A second possibility is that the paradox is based on false premises. Schizophrenia Bulletin. We conducted detailed structured clinical psychiatric interviews, anatomical-structural magnetic resonance imaging (MRI), sleep-deprived electroencephalogram (EEG) recordings, laboratory testing, and a comprehensive battery of psychological testing to better understand their clinical pictures. Those approaches include the use of the At Risk Mental State category (ARMS) and of standardized predictive tools. Our results suggest that the right inferior frontal gyrus plays an important role in brain control of urinary continence. We previously used PET and. When the threshold value was decreased to P < 0.005 without correction, there was a vast network of cortical and subcortical regions involved during urine withholding. Deconstructing Psychosis With Human Brain Imaging This review synthesizes our current knowledge on the neurobiology of psychosis from an array of in vivo brain-imaging studies. cannabinoid, dopaminergic, glutamatergic, GABAergic), as well as changes in dendritic spine morphology and upregulation of inflammatory markers. This compound, consistently detected by 1H NMR in vivo, was previously thought to ne present only in neurons. Deconstructing Psychosis With Human Brain Imaging . Blue means that the respective structures were relatively larger in patients than in healthy controls. These changes often align with molecular changes observed in post-mortem tissue from schizophrenia patients and correspond with schizophrenia-relevant behavioural change in rodents. interest in the transverse projection of each study was normalized to uptake per pixel in the cerebellum. Eager to obtain a “window to the mind,” neuroimaging has been embraced by investigators applying diverse methods to examine brain structure and function in psychiatric disorders. To gain insight into possible biological relationships between the genes implicated by these clusters, we mapped five of them to GO terms of the category “biological process” (AKT1, CNNM2, DISC1, DTNBP1, VAV3), then five to “cellular component” terms (AKT1, CNNM2, DISC1, DTNBP1, VAV3), and three to “molecular function” terms (AKT1, VAV3, ZNF804A). 15 Tebartz Van Elst , L , Baeumer , D , Lemieux , L , Woermann , FG , Koepp , M , Krishnamoorthy , S , et al. As a result, the effects of patient motion is corrected in real time. A meta-analysis of the pooled data in the literature on bipolar illness and signal hyperintensities revealed that the odds of having a T-2 hyperintensity are significantly greater for bipolar I than for normal comparison subjects.
