Psychol Med 2023; 53:2041-2049. [PMID: 37310333 PMCID: PMC10106305 DOI: 10.1017/s0033291721003780] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 08/30/2021] [Accepted: 09/01/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUND We aimed to identify unmet treatment needs for improving social and occupational functioning in early schizophrenia using a data-driven causal discovery analysis. METHODS Demographic, clinical, and psychosocial measures were obtained for 276 participants from the Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) trial at baseline and 6-months, along with measures of social and occupational functioning from the Quality of Life Scale. The Greedy Fast Causal Inference algorithm was used to learn a partial ancestral graph modeling causal relationships across baseline variables and 6-month functioning. Effect sizes were estimated using a structural equation model. Results were validated in an independent dataset (N = 187). RESULTS In the data-generated model, greater baseline socio-affective capacity was a cause of greater baseline motivation [Effect size (ES) = 0.77], and motivation was a cause of greater baseline social and occupational functioning (ES = 1.5 and 0.96, respectively), which in turn were causes of their own 6-month outcomes. Six-month motivation was also identified as a cause of occupational functioning (ES = 0.92). Cognitive impairment and duration of untreated psychosis were not direct causes of functioning at either timepoint. The graph for the validation dataset was less determinate, but otherwise supported the findings. CONCLUSIONS In our data-generated model, baseline socio-affective capacity and motivation are the most direct causes of occupational and social functioning 6 months after entering treatment in early schizophrenia. These findings indicate that socio-affective abilities and motivation are specific high-impact treatment needs that must be addressed in order to promote optimal social and occupational recovery.

Unfinished business: Functional outcomes in a randomized controlled trial of a three-year extension of early intervention versus regular care following two years of early intervention for psychosis. Acta Psychiatr Scand 2022; 145:86-99. [PMID: 34599603 DOI: 10.1111/acps.13377] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 09/25/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVE To investigate whether first-episode psychosis patients receiving extended early intervention had better functional outcomes than those in regular care and to examine the predictors of functional outcomes. METHODS This is a randomized controlled single-blind trial of 220 patients randomized after 2 years of early intervention to receive early intervention or regular care for the subsequent 3 years. Outcomes included cumulative time in functional recovery during the 3-year trial assessed using the Social and Occupational Functioning Assessment Scale (SOFAS); and employment/education at last assessment which were, respectively, analyzed using multiple linear regression and logistic regression, accounting for well-known predictors. Linear mixed and generalized linear models were also used to examine the course of SOFAS and employment/education over the 3-year period. RESULTS The extended early intervention and regular care groups did not differ on time in functional recovery (mean = 50.17 weeks, SD = 46.62 vs. mean = 46.18 weeks, SD = 51.54); percent employed/in school (60.4% vs. 68.8%) or change in SOFAS or employment/education status over time. SOFAS scores were stable between years 2 and 5. Individuals with longer periods of total symptom remission experienced significantly longer periods of functional recovery and were likelier to be employed/in school. Those who had completed high school were nine times likelier to be employed/studying. CONCLUSION Most individuals maintained functional gains accrued from 2 years of early intervention with no further improvement whether in extended early intervention or regular care. There was a gap between symptomatic and functional recovery, and one-third were unemployed/not in school at year 5. The lack of additional progress even in extended early intervention suggests that specific interventions addressing functional roles need to be provided beyond the first 2 years of early intervention. Sustaining symptom remission and high-school completion may be additional avenues for targeting functional recovery.

Early treatment response in first episode psychosis: a 7-T magnetic resonance spectroscopic study of glutathione and glutamate. Mol Psychiatry 2020; 25:1640-1650. [PMID: 32205866 PMCID: PMC7387300 DOI: 10.1038/s41380-020-0704-x] [Citation(s) in RCA: 54] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 02/18/2020] [Accepted: 02/24/2020] [Indexed: 01/07/2023]
Abstract
Early response to antipsychotic medications is one of the most important determinants of later symptomatic and functional outcomes in psychosis. Glutathione and glutamate have emerged as promising therapeutic targets for patients demonstrating inadequate response to dopamine-blocking antipsychotics. Nevertheless, the role of these neurochemicals in the mechanism of early antipsychotic response remains poorly understood. Using a longitudinal design and ultrahigh field 7-T magnetic resonance spectroscopy (MRS) protocol in 53 subjects, we report the association between dorsal anterior cingulate cortex glutamate and glutathione, with time to treatment response in drug naive (34.6% of the sample) or minimally medicated first episode patients with schizophreniform disorder, schizophrenia, and schizoaffective disorder. Time to response was defined as the number of weeks required to reach a 50% reduction in the PANSS-8 scores. Higher glutathione was associated with shorter time to response (F = 4.86, P = 0.017), while higher glutamate was associated with more severe functional impairment (F = 5.33, P = 0.008). There were no significant differences between patients and controls on measures of glutamate or glutathione. For the first time, we have demonstrated an association between higher glutathione and favorable prognosis in FEP. We propose that interventions that increase brain glutathione levels may improve outcomes of early intervention in psychosis.

Abstract
BACKGROUND: Neurocognitive and social cognitive impairments are core characteristics of psychotic disorders, which are present in the first episode of psychosis (FEP) and strongly predict poor social functioning. Addressing cognitive impairments through cognitive training and remediation (CTR) may be a crucial component of recovery-oriented treatment. AIMS: The objectives of this review were to (1) evaluate the CTR theoretical basis and intervention components and (2) examine the effects of CTR on cognition and social functioning in FEP. METHOD: A combined search of Ovid Medline, Embase, and Psych Info databases was conducted using keywords. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Quality and risk of bias were assessed using established instruments. RESULTS: Ten randomized controlled trials were included in this review and had an overall fair to poor quality. CTR interventions in FEP utilize a range of theoretical backgrounds, with most including a focus on higher order cognitive processes. Varied doses and intervention components are used. All but one study found improvements in at least one cognitive domain. Global cognition, verbal learning, and memory and executive function were most commonly improved. Three studies found an effect on a range of functional outcomes. CONCLUSIONS: A broad range of CTR interventions have promising effects for addressing cognitive impairments in FEP. Evidence of functional impact is less consistent. Further research is needed in FEP on CTR targeting sensory and perceptual processes, and to identify CTR intervention targets and treatment components that will lead to robust improvements in cognition and functioning.
