RESUMEN

OBJECTIVE: The severity and impact of hearing deficits among adults with schizophrenia spectrum disorders may become increasingly relevant with advancing age. This study evaluated hearing ability and associated psychosocial functioning among older adults aged 50-70. DESIGN: Cross-sectional analysis. SETTING: Four outpatient psychiatry clinics in New York City. PARTICIPANTS: Individuals aged 50-70 years with diagnoses of schizophrenia or schizoaffective disorder. MEASUREMENTS: Unaided pure tone air conduction audiometry conducted using a portable audiometry system determined the pure tone average (PTA) hearing threshold across four frequencies: 500, 1k, 2k, and 4k Hz. Better ear PTA defined the hearing threshold. Audiometry data retrieved from the U.S. National Health and Nutrition Examination Survey aided interpretation of sample hearing loss rates. Standard measures evaluated psychiatric symptoms, perceived impact of hearing impairment, loneliness, and quality of life. RESULTS: Among audiometry completers (N = 40), 35% (n = 14) demonstrated subclinical hearing loss (16-25 dB) and 35% (n = 14) had mild or worse hearing loss (≥26 dB). Rates were higher than expected based on age-based population data. Those who perceived hearing handicap rated it moderate (12.2%) or severe (7.3%); those who perceived tinnitus rated the impact as mild to moderate (12.2%) or catastrophic (2.4%). Neither psychiatric symptoms nor interviewer-rated quality of life was associated with hearing ability. Greater loneliness was significantly correlated with worse audiologic performance (r = 0.475, p <0.01) and greater perceived hearing handicap (r = 0.480, p <0.01). CONCLUSION: Identifying the need for hearing loss treatment among aging adults with schizophrenia spectrum disorders is important given the potential implications for social functioning, cognitive, and mental health.

RESUMEN

BACKGROUND: Adults with schizophrenia experience a range of neurocognitive problems that affect their daily functioning. Evidence for the efficacy of cognitive remediation in schizophrenia has been established, but its implementation in under-resourced community-based settings is less well-studied. In recent years, interventions have also focused on the strategy-learning approach in favor of drill-and-practice. Moreover, there is an increasing recognition to address social cognition and negative symptoms alongside neurocognition. This study attempts to carry out cognitive remediation in a community mental health setting. The Neuropsychological and Educational Approach to Remediation (NEAR) is used as the cognitive remediation intervention. Neurocognitive and social cognitive games will be introduced during the computer-assisted cognitive exercises sessions. In addition, the instructional technique will foster the use of metacognition and cognitive strategies. Moreover, metamotivation training will be the focus of some bridging sessions to enhance motivation to engage in goal-directed learning behaviors. The aims of the study are to 1) investigate the effects of cognitive remediation on neurocognition, social cognition and functional outcomes of participants with schizophrenia/schizoaffective disorders in community mental health settings; and 2) explore the mediators for change (eg: metamotivation, metacognition and negative symptoms) in cognitive performance and functional outcomes. METHODS: This randomized controlled trial will be conducted in three Singapore Anglican Community Services (SACS) centers, where standard psychiatric rehabilitation is delivered. Participants who are randomized to the experimental arm will receive cognitive remediation and psychiatric rehabilitation, while those randomized to the control arm will receive standard psychiatric rehabilitation only. Cognitive remediation is carried out three times a week for 12 weeks. It consists of computer-assisted cognitive exercises, as well as bridging groups to aid transfer of learning to daily living. Baseline, post-intervention and eight-week follow-up measurements will be collected. Group by time differences in cognitive performance, negative symptoms, metamotivation, metacognition, functioning and recovery will be analyzed across the three time points. Mediators for improvement in cognitive performance and functioning will also be explored. DISCUSSION: Findings of this research will add to the body of knowledge about the key therapeutic ingredients within a strategy-based cognitive remediation program and improve its implementation within under-resourced community settings. TRIAL REGISTRATION: This study has been registered with ClinicalTrials.gov (ID: NCT06286202). Date of registration: 29 February 2024. Date of last update: 21 May 2024.

RESUMEN

BACKGROUND: Cognitive deficits at the first episode of schizophrenia are predictive of functional outcome. Interventions that improve cognitive functioning early in schizophrenia are critical if we hope to prevent or limit long-term disability in this disorder. METHODS: We completed a 12-month randomized controlled trial of cognitive remediation and of long-acting injectable (LAI) risperidone with 60 patients with a recent first episode of schizophrenia. Cognitive remediation involved programs focused on basic cognitive processes as well as more complex, life-like situations. Healthy behavior training of equal treatment time was the comparison group for cognitive remediation, while oral risperidone was the comparator for LAI risperidone in a 2 × 2 design. All patients were provided supported employment/education to encourage return to work or school. RESULTS: Both antipsychotic medication adherence and cognitive remediation contributed to cognitive improvement. Cognitive remediation was superior to healthy behavior training in the LAI medication condition but not the oral medication condition. Cognitive remediation was also superior when medication adherence and protocol completion were covaried. Both LAI antipsychotic medication and cognitive remediation led to significantly greater improvement in work/school functioning. Effect sizes were larger than in most prior studies of first-episode patients. In addition, cognitive improvement was significantly correlated with work/school functional improvement. CONCLUSIONS: These results indicate that consistent antipsychotic medication adherence and cognitive remediation can significantly improve core cognitive deficits in the initial period of schizophrenia. When combined with supported employment/education, cognitive remediation and LAI antipsychotic medication show separate significant impact on improving work/school functioning.

RESUMEN

IntroductionWith the increasing enthusiasm to provide cognitive remediation (CR) as an evidence-based practice, questions arise as to what is involved in implementing CR in a large system of care. This article describes the first statewide implementation of CR in the USA, with the goal of documenting the implementation issues that care providers are likely to face when bringing CR services to their patients. METHODS: In 2014, the New York State Office of Mental Health set up a Cognitive Health Service that could be implemented throughout the state-operated system of care. This service was intended to broadly address cognitive health, to assure that the cognitive deficits commonly associated with psychiatric illnesses are recognized and addressed, and that cognitive health is embedded in the vocabulary of wellness. It involved creating a mechanism to train staff to recognize how cognitive health could be prioritized in treatment planning as well as implementing CR in state-operated adult outpatient psychiatry clinics. RESULTS: By 2017, CR was available at clinics serving people with serious mental illness in 13 of 16 adult Psychiatric Centers, located in rural and urban settings throughout New York state. The embedded quality assurance program evaluation tools indicated that CR was acceptable, sustainable, and effective. CONCLUSIONS: Cognitive remediation can be feasibly implemented in large systems of care that provide a multilevel system of supports, a training program that educates broadly about cognitive health and specifically about the delivery of CR, and embedded, ongoing program evaluation that is linked to staff supervision.

RESUMEN

During the past two decades, it has been amply documented that neuropsychiatric disorders (NPDs) disproportionately account for burden of illness attributable to chronic non-communicable medical disorders globally. It is also likely that human capital costs attributable to NPDs will disproportionately increase as a consequence of population aging and beneficial risk factor modification of other common and chronic medical disorders (e.g., cardiovascular disease). Notwithstanding the availability of multiple modalities of antidepressant treatment, relatively few studies in psychiatry have primarily sought to determine whether improving cognitive function in MDD improves patient reported outcomes (PROs) and/or is cost effective. The mediational relevance of cognition in MDD potentially extrapolates to all NPDs, indicating that screening for, measuring, preventing, and treating cognitive deficits in psychiatry is not only a primary therapeutic target, but also should be conceptualized as a transdiagnostic domain to be considered regardless of patient age and/or differential diagnosis.

RESUMEN

Cognitive deficits are a well-recognised issue for individuals diagnosed with schizophrenia spectrum disorders. Despite positive group findings for the use of cognitive remediation (CR) interventions, there are substantial individual differences in response to treatment. In addition, the aggregate CR literature reports low moderate effect sizes for cognitive and functional outcomes. Based on personalised medicine theory, this paper uses extant CR literature to examine the individual characteristics determined to predict treatment response. These characteristics, which fall into the broad categories of cognitive, psychological, and biological can be used as tailoring variables to personalise CR to an individual's unique profile. Personalisation through the use of these tailoring variables has the potential to improve the delivery of CR to maximise treatment outcomes.

RESUMEN

Cognitive impairments are common in homeless youth and negatively impact academic and vocational outcomes. We examined the feasibility and efficacy of cognitive interventions provided to 18- to 22-year-old homeless youth living in urban supportive housing. Ninety-one homeless youth were randomized to receive either targeted cognitive training (cognitive remediation) or general cognitive activation (computer skills training). Cognitive and psychological outcomes were assessed at baseline, after 13 and 26 sessions, and 1 month postintervention. A high dropout rate highlighted the feasibility challenges of treating this population. Intent-to-treat analysis found significant improvements across groups in specific and global measures of cognition and psychological distress, with no significant group differences. Transition-age homeless youth show improvements in cognitive and psychological functioning when engaged in interventions that address their cognitive development. This speaks to the malleability of cognitive skills in this cohort and lays the groundwork for future research to address their cognitive health.

RESUMEN

Cognitive deficits are a prominent and enduring aspect of schizophrenia, which pose a significant barrier to achieving functional goals. The most promising intervention for treating cognitive impairment is cognitive remediation (CR), a behaviorally based therapy associated with medium effect sizes for cognitive and functional outcomes. However, there is a sizeable group of nonresponders whose CR outcomes become limited when the therapeutic approach fails to address individual differences in baseline cognition, motivation variables, and the extent to which CR offers opportunities for generalization. This speaks to a need to develop cognitive interventions that are both personalized and scalable. Emerging data suggest that specific pharmacological agents have the potential to enhance and accelerate behaviorally based CR effects. This article will review the rationale and preliminary evidence to support combining CR and pharmacotherapy. We will review crucial aspects of cognitive interventions that offer the most promise for improving not only cognitive outcomes, but also for enhancing improvement in real-world functioning. Finally, we will address methodological issues to be considered for future research on combined pharmacological and CR interventions.

RESUMEN

While second-generation antipsychotics treat negative as well as positive symptoms, recovery for persons with schizophrenia remains elusive, in part because there are no FDA-approved medications that treat the cognitive deficits of schizophrenia (CDS). Recent work has identified agents that, when added to antipsychotics, improve cognition in schizophrenia. This work and hypothesized mechanisms of action will be reviewed.

RESUMEN

BACKGROUND AND HYPOTHESIS: With increasing recognition of the importance of cognitive health for recovery in people with psychosis, questions arise as to how to implement cognitive health services in large systems of care. This paper describes the implementation of cognitive health services in OnTrackNY (OTNY), a network of clinics delivering a Coordinated Specialty Care treatment model for early psychosis, with the goal of documenting the processes, challenges, and useful adaptations. STUDY DESIGN: In 2018, OTNY piloted a Cognitive Health Toolkit for implementation across 18 affiliated clinics. The toolkit intended to identify the cognitive health needs of individuals early in the course of psychosis and to integrate cognitive health into the vocabulary of wellness and recovery. Implementation involved creating mechanisms for staff training and support to, in turn, help participants improve how they use cognitive skills in daily life. STUDY RESULTS: The toolkit was disseminated to all 28 OTNY programs throughout New York state by 2023. When simple assessment and decision-making tools were embedded in routine care practices, the majority of participants identified that improving memory, attention, and critical thinking skills would be helpful. Consistently, about 70% of those asked wanted to learn more about how to better their cognitive health. CONCLUSIONS: Cognitive health services can be implemented in large systems of care that provide a multi-level system of implementation supports. Organizational facilitators of implementation include a training program to educate about cognitive health and the delivery of cognitive health interventions, and embedded quality assurance monitoring and improvement activities.

RESUMEN

OBJECTIVE: Stigma toward schizophrenia spectrum disorders is pervasive and negatively influences service access and delivery. Cognitive impairment associated with schizophrenia (CIAS) is common, but its association with stigma is unknown. In this study, the authors examined whether individuals with CIAS receiving cognitive remediation treatment report experiencing CIAS-related stigma and sought to establish associations between CIAS-related stigma and recovery-relevant outcomes. METHODS: Data from 48 individuals with schizophrenia spectrum diagnoses were drawn from a larger study evaluating cognitive remediation. Participants completed measures of CIAS-related stigma, internalized mental illness stigma, self-perceived cognitive impairment, cognitive performance, and interviewer-rated quality of life. RESULTS: CIAS-related stigma was commonly reported and significantly positively associated with internalized stigma and self-perceived cognitive impairment. CIAS-related stigma was also significantly negatively associated with motivation to engage in goal-directed behavior and daily activities. CONCLUSIONS: CIAS-related stigma exists and warrants additional exploration with regard to implications for psychiatric service delivery.

RESUMEN

AIM: Cognitive disturbances typically precede the onset of overt psychotic symptoms and represent a neurobiological marker for psychosis risk that is also associated with poor functional outcomes. The Measure of Insight into Cognition-Self Report (MIC-SR) is a widely used 12-item questionnaire that assesses the perceived frequency of cognitive impairment in the domains of executing functioning, attention, and memory. However, the MIC-SR is not available in Spanish, one of the most widely spoken languages worldwide. The present study aimed to provide a Spanish version of the MIC-SR and examine its psychometric properties in psychosis-risk and non-clinical Mexican young adults. METHODS: The sample comprised 621 participants who completed a battery of self-report measures via an online survey. Of the participants, 478 were non-clinical, and 143 met the screening criteria for a clinical high-risk for psychosis (CHR-positive). RESULTS: Confirmatory Factor Analyses supported a one-factor model, consistent with the findings for the original MIC-SR. The results showed adequate fit indices for the general model and the independent models for both groups, with high Cronbach's alpha coefficients. Furthermore, the CHR-positive group showed more frequent subjective cognitive problems on each of the 12 items, higher total scores, and higher average frequency than the non-clinical group. CONCLUSION: To our knowledge, this is the first translation of the MIC-SR into Spanish. Using the MIC-SR at the CHR stage may contribute to our understanding of cognitive processes associated with the onset of a psychotic disorder and provide valuable information in the context of detection and early intervention efforts.

RESUMEN

OBJECTIVE: To explore whether there is an association between serious mental illness (SMI) and hearing loss (HL) among US Hispanic adults. STUDY DESIGN AND SETTING: Cross-sectional epidemiological study (Hispanic Community Health Study), including multicentered US volunteers. METHODS: Multivariable linear regressions were conducted to study the association between SMI and HL. Adjustments were made for potential confounders including age, sex, education, vascular disease (hypertension or diabetes mellitus), and cognition. SMI was defined by (1) antipsychotic medication classification and (2) the use of at least 1 antipsychotic medication specifically used to treat SMI in clinical psychiatric practice. HL was measured by pure tone audiometry. RESULTS: A total of 7581 subjects had complete data. The mean age was 55.2 years (SD = 7.5 years) and the mean pure tone average in the better ear was 16.8 dB (SD = 10.7 dB). A total of 194 (2.6%) subjects were taking a HCHS-defined antipsychotic and 98 (1.3%) were taking at least 1 antipsychotic specifically used to treat SMI. On multivariable regression, use of HCHS's classified antipsychotics was associated with 3.75 dB worse hearing (95% confidence interval [CI] = 2.36-5.13, P < .001) and use of antipsychotics specific for SMI was associated with 4.49 dB worse hearing (95% CI = 2.56-6.43, P < .001) compared to those not using antipsychotics. CONCLUSION: SMI, as defined by either the use of HCHS-defined antipsychotics or the use of antipsychotic medication specific for SMI, is associated with worse hearing, controlling for potential confounders. Whether SMI contributes to HL, antipsychotic medication (through ototoxicity) contributes to HL, or whether HL contributes to SMI is unknown and warrants further investigation.

RESUMEN

OBJECTIVE: The authors characterized hearing loss among individuals diagnosed as having schizophrenia to inform provision of routine behavioral health services to this population. METHODS: Audiometry data collected between October 2019 and December 2021 from 84 community-dwelling adults with schizophrenia and 81 age-matched participants without the condition were analyzed. Rates of hearing loss were identified within groups and across age decades (20-50 years). Hearing threshold and rates of hearing loss were compared between groups. RESULTS: Participants with schizophrenia had significantly higher mean hearing thresholds (p=0.006), indicating worse hearing. This difference remained significant after controlling for age (p=0.01). A significantly larger proportion of participants with schizophrenia had mild hearing loss (24%) compared with age-matched participants (6%) (p=0.002), with higher rates of mild hearing loss observed across all ages. CONCLUSIONS: Screening for and detection of hearing loss among adults with schizophrenia may be an unmet need. Hearing loss is a treatable source of cognitive and psychosocial disability, warranting scalable assessment and intervention practices.

RESUMEN

BACKGROUND: Hearing loss (HL) is associated with adverse cognitive, mental, and physical health outcomes. There is evidence that across age groups HL is more prevalent in people with schizophrenia than the general population. Given that people with schizophrenia may already be vulnerable to cognitive and psychosocial disability, we sought to examine how hearing ability relates to concurrent levels of cognitive, mental and daily functioning. METHODS: Community-dwelling adults with schizophrenia (N = 84) ages 22-50 completed pure tone audiometry assessments. Hearing threshold (in decibels) was defined as the lowest detectable pure tone at 1000 Hz. Pearson correlation was used to test the hypothesis that higher hearing thresholds (worse hearing) would be significantly associated with poorer performance on the Brief Assessment of Cognition in Schizophrenia (BACS). Additional analyses explored the relationships between audiometric threshold and functional capacity measured with the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) and symptoms severity rated on the Positive and Negative Syndrome Scale (PANSS). RESULTS: Hearing threshold was inversely and significantly correlated with the BACS composite score (r = -0.27, p = 0.017). This relationship was reduced but remained significant after controlling for age (r = -0.23, p = 0.04). Hearing threshold was not associated with VRFCAT or psychiatric symptom measures. CONCLUSIONS: While schizophrenia and HL are independently associated with cognitive impairment, the magnitude of impairment in this sample was greater among those with poorer hearing. Findings warrant further mechanistic study of the relationship between hearing impairment and cognition and have implications for addressing modifiable health risk factors for higher morbidity and mortality in this vulnerable population.

RESUMEN

Early auditory processing (EAP) deficits are prevalent in schizophrenia and linked to disturbances in higher order cognition and daily functioning. Treatments that target EAP have the potential to drive downstream cognitive and functional improvements, but clinically feasible means to detect EAP impairment are lacking. This report describes the clinical feasibility and utility of using the Tone Matching (TM) Test to assess EAP in adults with schizophrenia. Clinicians were trained to administer the TM Test as part of a baseline cognitive battery to inform choice of cognitive remediation (CR) exercises. Only if the TM Test indicated EAP impairment, were the recommended CR exercises to include EAP training. Results indicated clinicians included the TM Test in all baseline assessments and identified 51.72% as EAP impaired. There were significant positive relationships between TM Test performance and cognitive summary scores, confirming instrumental validity. All clinicians found the TM Test useful for CR treatment planning. CR participants with impaired EAP spent significantly more training time on EAP exercises compared to CR participants with intact EAP (20.11% vs 3.32%). This study found that it is feasible to use the TM Test in community clinics and the test was perceived as clinically useful for personalizing treatment.

RESUMEN

Schizophrenia is a major mental disorder that affects approximately 1% of the population worldwide. Cognitive deficits are a key feature of the disorder and a primary cause of long-term disability. Over the past decades, significant literature has accumulated demonstrating impairments in early auditory perceptual processes in schizophrenia. In this review, we first describe early auditory dysfunction in schizophrenia from both a behavioral and neurophysiological perspective and examine their interrelationship with both higher order cognitive constructs and social cognitive processes. Then, we provide insights into underlying pathological processes, especially in relationship to glutamatergic and N-methyl-D-aspartate receptor (NMDAR) dysfunction models. Finally, we discuss the utility of early auditory measures as both treatment targets for precision intervention and as translational biomarkers for etiological investigation. Altogether, this review points out the crucial role of early auditory deficits in the pathophysiology of schizophrenia, in addition to major implications for early intervention and auditory-targeted approaches.

RESUMEN

Questions remain regarding whether the transition and continued use of telehealth was associated with changes in treatment engagement among patients with serious mental illness (SMI). Using NYS Medicaid claims, we identified 116,497 individuals with SMI receiving outpatient mental health services from September 1, 2019-February 28, 2021 and a comparison cohort of 101,995 from September 1, 2017-February 28, 2019 to account for unmeasured and seasonal variation. We characterized engagement in three 6-month increments (T0-T1-T2) using clinically meaningful measures of high, partial, low, and none. Subgroup differences were compared, and telehealth users were compared to those with only in-person visits. Engagement, as characterized, was largely maintained during COVID. The 19.0 % with only in-person visits during COVID had different characteristics than telehealth users. Telehealth use was greater among younger people by T2 (33.1 %), women (57.7 %), non-Hispanic White people (38.9 %), and those with MDD (18.0 %), but lower among non-Hispanic Black people, in NYC, and those with schizophrenia or SUD. Most telehealth users were highly engaged (77.1 %); most using only in-person services had low engagement (47.5 %). The shift to telehealth preserved access to many outpatient services for this SMI population. Exploring reasons for not using telehealth may identify opportunities to increase care access.

RESUMEN

BACKGROUND: Patients with schizophrenia show reduced NMDA glutamate receptor-dependent auditory plasticity, which is rate limiting for auditory cognitive remediation (AudRem). We evaluate the utility of behavioral and neurophysiological pharmacodynamic target engagement biomarkers, using a d-serine+AudRem combination. METHODS: Forty-five participants with schizophrenia or schizoaffective disorder were randomized to 3 once-weekly AudRem visits + double-blind d-serine (80, 100, or 120 mg/kg) or placebo in 3 dose cohorts of 12 d-serine and 3 placebo-treated participants each. In AudRem, participants indicated which paired tone was higher in pitch. The primary outcome was plasticity improvement, operationalized as change in pitch threshold between AudRem tones [(test tone Hz - reference tone Hz)/reference tone Hz] between the initial plateau pitch threshold (mean of trials 20-30 of treatment visit 1) to pitch threshold at the end of visit(s). Target engagement was assessed by electroencephalography outcomes, including mismatch negativity (pitch primary). RESULTS: There was a significant overall treatment effect for plasticity improvement (p = .014). Plasticity improvement was largest within the 80 and 100 mg/kg groups (p < .001, d > 0.67), while 120 mg/kg and placebo-treated participants showed nonsignificant within-group changes. Plasticity improvement was seen after a single treatment and was sustained on subsequent treatments. Target engagement was demonstrated by significantly larger mismatch negativity (p = .049, d = 1.0) for the 100 mg/kg dose versus placebo. CONCLUSIONS: Our results demonstrate sufficient proof of principle for continued development of both the d-serine+AudRem combination and our target engagement methodology.
