[49,50,51] deterioration of which is the primary feature of schizophrenia. Privacy, Help Saccadic abnormalities were revealed in the clinical (schizophrenia) and pre-clinical (clinical high risk) populations that provide further evidence for assessing saccadic abnormalities as a possible neurobiological marker for schizophrenia. Abstract. In such studies, visual targets are usually presented in the center of the visual field, and the subject's head remains fixed. Br J Psychiatry. Saccades can be measured precisely and with a number of reliable parameters. 2007 Sep;95(1-3):54-60. doi: 10.1016/j.schres.2007.06.022. Neuropsychol Rev. Antisaccade errors reflect failures of response suppression [15].

However, less is known about saccades in individuals . Subjects were seated comfortably in a quiet, sound- and light-attenuated darkened room. The Cegalis and Sweeney (1981) article addresses the issue of attentional influences on smooth pursuit. Horizontal eye movements were recorded by using videonystagmograph. Physiological dysfunction of dorsolateral prefrontal cortex in schizophrenia III. Abnormal smooth pursuit eye movement (SPEM) has been proposed as a trait marker in schizophrenia. Previous research suggests that performance in reflexive saccades is unimpaired in schizophrenia patients 21-25 and their full biological siblings. Crawford TJ, Haeger B, Kennard C, Reveley MA, Henderson L. Saccadic abnormalities in psychotic patients: I. Neuroleptic-free psychotic patients. Prefrontal cortex, negative symptoms, and schizophrenia: an MRI study. Exclusion criteria for all subjects included neurological hard signs, history of stroke and head injury, presence of drug induced extrapyramidal disorders, visual impairment other than refractive errors. Reliability of smooth pursuit, fixation, and saccadic eye movements. As it has been mentioned by Pierrot-Deseilligny et al. The dorsolateral prefrontal cortex (DLPFC) is known for its involvement in executive functions (such as working memory, cognitive flexibility, planning, inhibition and etc.) [Neurological soft signs: meaning and relevance along the course of psychiatric illness. The assessment of saccadic movements in schizophrenia patients as well as in clinical high-risk state for psychosis individuals (CHR) as a part of schizophrenia continuum may be useful in validation of saccadic movements as a possible biomarker. Acta Psychiatr Scand. Found insideThis book describes the state-of-the-art of treatment of schizophrenia and reflects its development in 22 chapters written by leading authorities in the field Schizophrenia research is in a dynamic state; this text gives a foothold for ... Proc Natl Acad Sci U S A. Bethesda, MD 20894, Copyright BMC Psychiatry Saccade control: a quick movement of the eyes from one point to another; Visual search: . Saccadic abnormalities were revealed in the clinical (schizophrenia) and pre-clinical (clinical high risk) populations that provide further evidence for assessing saccadic abnormalities as a possible neurobiological marker for schizophrenia. The worse performance on the saccade task in schizophrenia patients compared to controls may be explained by the brain error detector failure or by the corollary discharge (CD) dysfunction, a mechanism for distinguishing self-generated percepts from externally generated percepts [66,67,68]. Found insideThis is a classic edition of Christopher Frith’s award winning book on cognitive neuropsychology and schizophrenia, which now includes a new introduction from the author. Keywords: 2019 Dec;269(8):921-930. doi: 10.1007/s00406-018-0973-4. In: Gaebel W, editor. Childhood-onset schizophrenia: There is an increased number of anticipatory saccades and intrusive saccades during smooth pursuit eye movements. CHR subjects were characterized by the presence of one of the groups of criteria: (1) Ultra High Risk criteria [38], (2) Basic Symptoms criteria (COPER and COGDIS) [39] and (3) negative symptoms and formal thought disorders (FTD). 2000;97:72–6. Would you like email updates of new search results? Broerse A, Crawford TJ, der Boer JA. Back-up saccades and square-wave jerks were also counted but occurred infrequently and were omitted from statistical analysis. Objective Valproic acid (VPA) has been suggested as a potential adjunct therapy in schizophrenia for the treatment of clinical symptoms and cognitive deficits. Minimal accuracy was found in the DS group. Performance during reflexive and predictive saccades, antisaccades and predictive smooth pursuit was compared between patients with OCD (n=22), patients with schizophrenia (n=21) and healthy subjects (n=24). A re-examination of the positive-negative dichotomy. Participants from DS group made more errors in antisaccade task compared to NS and PS groups. However, less evidence is available on saccade performance in relation to schizotypy, a personality constellation harboring risk for . Arch Gen Psychiatry. However, in every-day life, targets may also appear in the periphery. Nieman DH, Bour LJ, Linszen DH, Goede J, Koelman JH, Ongerboer de Visser BW. So, our results support that eye movement alterations are possible markers of clinical high risk of psychosis. un-ta; 1991. The Kolmogorov-Smirnov test was performed to assess the normality of distribution. Vis Res. Epub 2020 Mar 6. Schizophr Res. This study is among the first to investigate eye and head movements in . Cognition. Previous studies have suggested that these types of saccades do not represent important schizophrenia endopheno-types (Clementz, Sweeney, Hirt, & Haas, 1990; Lencer . 1908;31:451–89. Healthy control group was represented by sex and age matched volunteers from hospital staff. 2017;18(4):733. The goal of the following series of experiments was to advance our understanding of two particular cognitive functions related to control of action in schizophrenia, response inhibition and response monitoring, using two experimental ... Brain Cogn. Objectives: Oculomotor dysfunction is one of the most replicated findings in schizophrenia. 2002;99(6):4026–31. Schizophrenia patients performed worse than controls in predictive, reflexive and antisaccade tasks. Dimitri-Valente G, Rigucci S, Manfredi G, Girardi P, Ferracuti S. Riv Psichiatr. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Saccadic eye movements. By contrast to Caldini study [32], we found that the error rate in antisaccade task was significantly higher in CHR compared to controls. One year later, Holzman found that the same abnormality was also present in non-schizophrenic healthy . 2018;17(3):252–8. eCollection 2021.

In the general group of participants we found correlations between the error rates in antisaccade task and: latencies of predictive saccades (r = 0.223, p < 0.001), accuracy of predictive saccades (r = − 0.298, p < 0.001) and accuracy of reflexive saccades (r = − 0.311, p < 0.001). Impaired performance in the predictive saccades test has previously been reported in schizophrenia patients [22, 23]. statement and The study included 156 patients who met the ICD-10 criteria for schizophrenia: 42 individuals at clinical high-risk-state for psychosis and 61 healthy controls. Neuroreport. We did not find any difference in accuracy of predictive saccades between PS, DS, CHR and controls. 2017. https://doi.org/10.1016/j.schres.2017.04.028. zwolfgang July 12, 2021, 7:04pm #1. The use of the different paradigms (AS, MGS) revealed distinct profiles depending on the stage of the disease, indicating that some alterations could be pure endophenotypic markers of vulnerability for schizophrenia, while others could be markers of the disease progression. Written informed consent was obtained from all participants. Negative symptoms in schizophrenia. Brain Cogn. Myles JB, Rossel SL, Phillipou A, Thomas E, Gurvich C. Insights to the schizophrenia continuum: a systematic review of saccadic eye movements in schizotypy and biological relatives of schizophrenia patients. Neuropsychology. Various abnormal eye movements such as smooth pursuit eye movements deficits, abnormal saccadic eye movements, and other abnormal eye movements in schizophrenia resembles with "Paryakula drishti/Chakshusho aakulata/Chakshusho apasarpanam" of Unmada. The accuracy of predictive saccades was also different from controls only in the NS schizophrenia group. Moskow: Izd-vo Mosk. 2004;56(2):198–214. All participants gave their written, informed consent before enrolment in the study or the guardians of these participants provided consent on their behalf. 8600 Rockville Pike However the association between saccadic abnormalities and particular clinical syndromes remains unclear.
