Abstract
Compared to peers, children and adolescents with obsessive-compulsive disorder (OCD) are at increased risk of developing psychotic disorders. Yet very few studies have examined early indicators of psychosis in pediatric OCD. In the present study, 52 youth with a primary diagnosis of OCD (Mage = 15.66 [SD = 2.33], 59.6% girls) were interviewed using the Schizophrenia Proneness Instrument Child and Adolescent version (SPI-CY), which is a comprehensive clinical interview assessing both Cognitive-Perceptual basic symptoms (COPER) and high-risk criterion Cognitive Disturbances (COGDIS). Associations between COPER/COGDIS symptoms and demographic and clinical characteristics were examined. Findings showed that COPER or COGDIS symptoms were present in 44% of participants, with no significant difference between girls and boys. Psychotic vulnerability was associated with an earlier age of OCD onset, greater OCD severity, poorer insight, and more contamination/cleaning symptoms. Psychotic vulnerability was also strongly associated with worse psychosocial functioning. Findings suggest that early indicators of psychosis are frequent in pediatric OCD and associated with more severe OCD and poorer functioning. Research examining how psychotic vulnerability is associated with short- and long-term outcomes for youth with OCD is needed.

Assessment of cognitive impairment in psychosis spectrum disorders through self-reported and interview-based measures. Eur Arch Psychiatry Clin Neurosci 2022; 272:1183-1192. [PMID: 35362774 DOI: 10.1007/s00406-022-01399-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 03/14/2022] [Indexed: 11/25/2022]
Abstract
Self-reported and interview-based measures can be considered coprimary measures of cognitive performance. We aimed to ascertain to what extent cognitive impairment in psychotic disorders, as assessed with a neuropsychological battery, is associated with subjective cognitive complaints compared to difficulties in daily activities caused by cognitive impairment. We assessed 114 patients who had a psychotic disorder with a set of neuropsychological tests and two additional measures: the Cognitive Assessment Interview-Spanish version (CAI-Sp) and the Frankfurt Complaint Questionnaire (FCQ). Patients also underwent a clinical assessment. The CAI-Sp correlated significantly with all the clinical dimensions, while the FCQ correlated only with positive and depressive symptoms. The CAI-Sp correlated significantly with all cognitive domains, except for verbal memory and social cognition. The FCQ was associated with attention, processing speed and working memory. The combination of manic and depressive symptoms and attention, processing speed, working memory and explained 38-46% of the variance in the patients' CAI-Sp. Education and negative symptoms, in combination with attention, processing speed, and executive functions, explained 54-59% of the CAI-Sp rater's variance. Only negative symptoms explained the variance in the CAI-Sp informant scores (37-42%). Depressive symptoms with attention and working memory explained 15% of the FCQ variance. The ability to detect cognitive impairment with the CAI-Sp and the FCQ opens the possibility to consider these instruments to approximate cognitive impairment in clinical settings due to their ease of application and because they are less time-consuming for clinicians.

Bridging the phenomenological gap between predictive basic-symptoms and attenuated positive symptoms: a cross-sectional network analysis. SCHIZOPHRENIA 2022; 8:68. [PMID: 36002447 PMCID: PMC9402628 DOI: 10.1038/s41537-022-00274-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 07/22/2022] [Indexed: 11/29/2022]
Abstract
Attenuated positive symptoms (APS), transient psychotic-like symptoms (brief, limited intermittent psychotic symptoms, BLIPS), and predictive cognitive-perceptive basic-symptoms (BS) criteria can help identify a help-seeking population of young people at clinical high-risk of a first episode psychosis (CHRp). Phenomenological, there are substantial differences between BS and APS or BLIPS. BS do not feature psychotic content as delusion or hallucinations, and reality testing is preserved. One fundamental problem in the psychopathology of CHRp is to understand how the non-psychotic BS are related to APS. To explore the interrelationship of APS and predictive BS, we fitted a network analysis to a dataset of 231 patients at CHRp, aged 24.4 years (SD = 5.3) with 65% male. Particular emphasis was placed on points of interaction (bridge symptoms) between the two criteria sets. The BS ‘unstable ideas of reference’ and “inability to discriminate between imagination and reality” interacted with attenuated delusional ideation. Perceptual BS were linked to perceptual APS. Albeit central for the network, predictive cognitive basic BS were relatively isolated from APS. Our analysis provides empirical support for existing theoretical accounts that interaction between the distinct phenomenological domains of BS and APS is characterized by impairments in source monitoring and perspective-taking. Identifying bridge symptoms between the symptom domains holds the potential to empirically advance the etiological understanding of psychosis and pave the way for tailored clinical interventions.

Front Psychiatry 2021; 12:777378. [PMID: 34899430 PMCID: PMC8656455 DOI: 10.3389/fpsyt.2021.777378] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 10/22/2021] [Indexed: 12/12/2022] Open
Abstract
Objective: Remission in schizophrenia patients is associated with neurocognitive, social, and role functioning during both the early and chronic stages of schizophrenia. It is well-established that the amplitudes of duration mismatch negativity (dMMN) and frequency MMN (fMMN) are reduced in schizophrenia patients. However, the potential link between MMN and remission has not been established. In this study, we investigated the relationship between MMNs and remission in first-episode schizophrenia (FES) and their association with neurocognitive and social functioning. Method: dMMN and fMMN were measured in 30 patients with FES and 22 healthy controls at baseline and after a mean of 3 years. Clinical symptoms and cognitive and social functioning in the patients were assessed at the time of MMN measurements by using the Positive and Negative Syndrome Scale (PANSS), modified Global Assessment of Functioning (mGAF), Schizophrenia Cognition Rating Scale (SCoRS), and the Brief Assessment of Cognition in Schizophrenia (BACS). Remission of the patients was defined using the criteria by the Remission in Schizophrenia Working Group; of the 30 patients with FES, 14 achieved remission and 16 did not. Results: Baseline dMMN amplitude was reduced in FES compared to healthy controls. Further, baseline dMMN in the non-remitters had decreased amplitude and prolonged latency compared to the remitters. MMN did not change during follow-up period regardless of parameters, diagnosis, or remission status. Baseline dMMN amplitude in FES was correlated with future SCoRS and PANSS total scores. Logistic regression analysis revealed that dMMN amplitude at baseline was a significant predictor of remission. Conclusions: Our findings suggest that dMMN amplitude may be a useful biomarker for predicting symptomatic remission and improvement of cognitive and social functions in FES.
