RESUMO

Mendelian and early-onset severe psychiatric phenotypes often involve genetic variants having a large effect, offering opportunities for genetic discoveries and early therapeutic interventions. Here, the index case is an 18-year-old boy, who at 14 years of age had a decline in cognitive functioning over the course of a year and subsequently presented with catatonia, auditory and visual hallucinations, paranoia, aggression, mood dysregulation, and disorganized thoughts. Exome sequencing revealed a stop-gain mutation in RCL1 (NM_005772.4:c.370 C > T, p.Gln124Ter), encoding an RNA 3'-terminal phosphate cyclase-like protein that is highly conserved across eukaryotic species. Subsequent investigations across two academic medical centers identified eleven additional cases of RCL1 copy number variations (CNVs) with varying neurodevelopmental or psychiatric phenotypes. These findings suggest that dosage variation of RCL1 contributes to a range of neurological and clinical phenotypes.

RESUMO

BACKGROUND: Despite the existing research exploring caregiver burden in adult psychosis, few studies have examined the experience of providing care to children diagnosed with psychotic disorders (PDs) and those identified as having clinical high risk for psychosis (CHR-P). OBJECTIVE: This study measured the level of burden in caregivers of children with PD and CHR-P and examined associated risk factors, including social support, caregiver-child relationship, severity of illness, and frequency of psychiatric hospitalizations. METHODS: A total of 56 caregivers completed validated measures and provided demographic information. Measures included the Zarit Burden Interview, the Multidimensional Scale of Perceived Social Support, the Behavior Assessment System for Children, Third Edition, Parenting Relationship Questionnaire-Child and Adolescent Form (BASC-3 PRQ-CA), and the Clinical Global Impression-Severity scale. RESULTS: The majority of caregivers were women (86%), mothers (84%), White (63%), married (66%), working full-time (50%), college-educated (79%), and whose mean age was 45.7 years (SD = 8.09). Nearly half of the caregivers (45%) reported a high level of caregiver burden, 39% rated their burden in the mild to moderate range, and 16% reported little to no burden. There was no significant difference in mean burden between PD and CHR-P groups. Higher caregiver burden was associated with lower levels of social support (r = -.408, p = .002), lower levels of parenting confidence (r = -.514, p < .001), higher levels of relational frustration (r = .612, p < .001), and higher severity of illness (r = .316 p = .025). CONCLUSIONS: These findings underscore the critical unmet need for support for caregivers of children with PD and CHR-P. Applications to clinical practice are discussed.

RESUMO

BACKGROUND: TRRAP encodes a multidomain protein kinase that works as a genetic cofactor to influence DNA methylation patterns, DNA damage repair, and chromatin remodeling. TRRAP protein is vital to early neural developmental processes, and variants in this gene have been associated with schizophrenia and childhood disintegrative disorder. CASE PRESENTATION: Here, we report on a patient with a de novo nonsynonymous TRRAP single-nucleotide variant (EST00000355540.3:c.5957G > A, p.Arg1986Gln) and early onset major depression accompanied by a psychotic episode (before age 10) that occurred in the context of longer standing nonverbal learning disability and a past history of obsessions and compulsions. CONCLUSIONS: The de novo variant and presentation of very early onset psychosis indicate a rare Mendelian disorder inheritance model. The genotype and behavioral abnormalities of this patient are reviewed.

RESUMO

BACKGROUND: Previous research has demonstrated elevated rates of suicide attempts and ideation in individuals with psychosis. This study investigated rates and severity of suicidal behavior in youth with and at clinical high risk for psychosis, and examined the positive, negative, and disorganized symptoms associated with suicidal behaviors among the clinical high risk group. METHODS: Eighty-six youth ages 7-18 (n=21 non-clinical controls [NCC], n=40 clinical high risk [CHR], n=25 diagnosed psychotic disorder [PD]) were recruited. CHR and PD participants were identified using the Structured Interview for Prodromal Symptoms (SIPS) and Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL). All participants completed the Suicide Behaviors Questionnaire-Revised (SBQ-R). RESULTS: Findings indicated significantly higher levels of suicidal behavior among CHR and PD relative to NCC participants (F=7.64, p=0.001). 17.5% of CHR participants had previously attempted suicide. Dysphoric Mood and Odd Behavior or Appearance were significantly correlated with suicidal behavior severity among CHR youth. CONCLUSION: Suicidal behavior was observed with greater frequency and severity in the CHR and PD groups than in the NCC group. CHR suicidal behavior severity was correlated most strongly with Dysphoric Mood and Odd Behavior or Appearance, a relationship which warrants further investigation.

RESUMO

Copy number variability at 16p13.11 has been associated with intellectual disability, autism, schizophrenia, epilepsy, and attention-deficit hyperactivity disorder. Adolescent/adult- onset psychosis has been reported in a subset of these cases. Here, we report on two children with CNVs in 16p13.11 that developed psychosis before the age of 7. The genotype and neuropsychiatric abnormalities of these patients highlight several overlapping genes that have possible mechanistic relevance to pathways previously implicated in Autism Spectrum Disorders, including the mTOR signaling and the ubiquitin-proteasome cascades. A careful screening of the 16p13.11 region is warranted in patients with childhood onset psychosis.

RESUMO

Highly penetrant mutations leading to schizophrenia are enriched for genes coding for N-methyl-D-aspartate receptor signaling complex (NMDAR-SC), implicating plasticity defects in the disease's pathogenesis. The importance of plasticity in neurodevelopment implies a role for therapies that target these mechanisms in early life to prevent schizophrenia. Testing such therapies requires noninvasive methods that can assess engagement of target mechanisms. The auditory N100 is an obligatory cortical response whose amplitude decreases with tone repetition. This adaptation may index the health of plasticity mechanisms required for normal development. We exposed participants aged 5 to 17 years with psychosis (n = 22), at clinical high risk (CHR) for psychosis (n = 29), and healthy controls (n = 17) to an auditory tone repeated 450 times and measured N100 adaptation (mean amplitude during first 150 tones - mean amplitude during last 150 tones). N100 adaptation was reduced in CHR and psychosis, particularly among participants <13 years old. Initial N100 blunting partially accounted for differences. Decreased change in the N100 amplitude with tone repetition may be a useful marker of defects in neuroplastic mechanisms measurable early in life.

RESUMO

This paper describes how psychology faculty positions in academic health centers (AHCs) have evolved to meet the changing needs in healthcare. In that context, the roles of psychologists have expanded significantly to include a wide array of clinical responsibilities, teaching and supervisory roles, administrative functions, research initiatives, and academic scholarship. Traditionally, faculty compensation plans have been calculated through the use of Relative Value Units which are primarily based on clinical service delivery, hence, incomplete when attempting to account for these growing academic responsibilities. This paper reviews the need to expand the ways in which the work provided by psychologists is appropriately identified and compensated for in AHCs. Drawing upon six models utilized in other areas of medical education, this paper describes the potential utility of incorporating Educational Value Units as a metric for capturing this expanding set of academic responsibilities and systematically incorporating them into a psychologist's job design. Recommendations for future considerations are provided.

RESUMO

BACKGROUND: Schizophrenia is a severe, disabling and prevalent mental disorder without cure and with a variable, incomplete pharmacotherapeutic response. Prior to onset in adolescence or young adulthood a prodromal period of abnormal symptoms lasting weeks to years has been identified and operationalized as clinically high risk (CHR) for schizophrenia. However, only a minority of subjects prospectively identified with CHR convert to schizophrenia, thereby limiting enthusiasm for early intervention(s). This study utilized objective resting electroencephalogram (EEG) quantification to determine whether CHR constitutes a cohesive entity and an evoked potential to assess CHR cortical auditory processing. METHODS: This study constitutes an EEG-based quantitative neurophysiological comparison between two unmedicated subject groups: 35 neurotypical controls (CON) and 22 CHR patients. After artifact management, principal component analysis (PCA) identified EEG spectral and spectral coherence factors described by associated loading patterns. Discriminant function analysis (DFA) determined factors' discrimination success between subjects in the CON and CHR groups. Loading patterns on DFA-selected factors described CHR-specific spectral and coherence differences when compared to controls. The frequency modulated auditory evoked response (FMAER) explored functional CON-CHR differences within the superior temporal gyri. RESULTS: Variable reduction by PCA identified 40 coherence-based factors explaining 77.8% of the total variance and 40 spectral factors explaining 95.9% of the variance. DFA demonstrated significant CON-CHR group difference (P <0.00001) and successful jackknifed subject classification (CON, 85.7%; CHR, 86.4% correct). The population distribution plotted along the canonical discriminant variable was clearly bimodal. Coherence factors delineated loading patterns of altered connectivity primarily involving the bilateral posterior temporal electrodes. However, FMAER analysis showed no CON-CHR group differences. CONCLUSIONS: CHR subjects form a cohesive group, significantly separable from CON subjects by EEG-derived indices. Symptoms of CHR may relate to altered connectivity with the posterior temporal regions but not to primary auditory processing abnormalities within these regions.

RESUMO

OBJECTIVE: Widespread use of diagnostic tools like the Structured Interview for Prodromal Symptoms (SIPS) has highlighted that youth at Clinical High Risk for Psychosis (CHR-P) present with heterogeneous symptomatology. This pilot study aims to highlight the range of clinical characteristics of CHR-P youth, investigate the role of the non-positive (negative, disorganization, and general) symptoms in risk assessment, and determine if specific profiles are associated with severe symptomatology. METHODS: 38 participants aged 7-18 were administered the SIPS and designated as CHR-P. Descriptive statistics and mean difference t-tests were used to describe the range in prevalence and severity of SIPS symptoms and to identify symptoms associated with greater overall symptomatology. RESULTS: Participants who had a greater number of positive symptoms also had significantly more negative, disorganization, and general symptoms. A number of SIPS symptoms were associated with greater number of positive symptoms. CONCLUSION: CHR-P youth represent a heterogeneous group, presenting with a wide range in clinical presentation as reflected in both the number of SIPS symptoms and their severity. Though the severity and duration of positive SIPS symptoms determines the CHR-P classification, high ratings on several of the other SIPS negative, disorganization, and general items may be useful indicators of elevated symptomatology.

RESUMO

OBJECTIVE: Suicide is a leading cause of death among adolescents, and suicidal thoughts represent key predictors to suicidal behavior. Yet, suicidal thoughts can be challenging to accurately assess. Symptoms that commonly co-occur with suicidal thoughts, such as depressive symptoms, may provide valuable information for predicting these thoughts. Although clinicians commonly collect multi-informant reports about adolescent depressive symptoms, these reports often yield discrepant findings as individual predictors of adolescents' suicidal thoughts. METHOD: We tested the ability of specific patterns of multi-informant reports to predict adolescents' suicidal thoughts. Ninety adolescent inpatients and their parents (i.e., "dyads") reported on adolescent depressive symptoms, and adolescents completed self-report assessments of suicidal thoughts at baseline and three-month follow-up. RESULTS: Dyads displayed variability in reporting patterns, and these patterns uniquely predicted suicidal thoughts. Adolescents reporting elevated depressive symptoms displayed increased concurrent suicidal thoughts relative to adolescents reporting subthreshold depressive symptoms, regardless of parent report. Yet, only adolescents who reported elevated depressive symptoms and whose parents reported subthreshold adolescent depressive symptoms displayed increased future suicidal thoughts. CONCLUSIONS: Identifying patterns of multiple informants' reports about adolescent depressive symptoms may improve the prediction of suicidal thoughts. These findings have important implications for assessing adolescents at risk for suicide.

RESUMO

BACKGROUND: Early identification and intervention is a gold standard for psychotic disorders, for which delays in care can have serious consequences. Screening for psychosis in primary care may circumvent barriers related to stigma and facilitate shorter pathways to care. Yet, there is debate regarding the benefit-risk balance for psychosis screening in general adolescent populations. METHODS: Primary care patients of an adolescent/young adult medical clinic in the US ages 14-21 self-administered surveys assessing age, sex, receipt of psychotherapy, and occurrence, frequency (1-5), and distress (0-3) for 23 psychosis risk (PR) symptoms, including 6 general/nonspecific items and 17 psychosis-specific items. Participants also completed the 9-item Patient Health Questionnaire (PHQ-9); scores of ≥10 suggested clinically significant depressive symptoms. Analyses characterized PR symptoms and examined associations of PR symptom distress with current therapy and depressive symptom severity. RESULTS: Of 212 patients who completed the survey, 75% endorsed ≥1 PR symptom and 27% rated ≥3 on distress for psychosis-specific items. Those with high PHQ-9 scores reported higher PR distress overall (t = -6.1, df = 52.3, p < 0.001) but not on psychosis-specific items such as hallucinations and suspiciousness. One in 9 participants reported heightened PR distress without being in therapy or having high depressive symptoms. CONCLUSIONS: Most adolescents in this primary care sample endorsed symptoms associated with PR. Distress related to these symptoms was less common but occurred even in the absence of depressive symptoms. PR screening only in youth with high depressive symptom screens or in mental health care may miss youth needing further assessment for psychosis.

RESUMO

OBJECTIVE: Copy number variants (CNVs) are strongly associated with neurodevelopmental and psychotic disorders. Early-onset psychosis (EOP), where symptoms appear before 18 years of age, is thought to be more strongly influenced by genetic factors than adult-onset psychotic disorders. However, the prevalence and effect of CNVs in EOP is unclear. METHODS: The authors documented the prevalence of recurrent CNVs and the functional impact of deletions and duplications genome-wide in 137 children and adolescents with EOP compared with 5,540 individuals with autism spectrum disorder (ASD) and 16,504 population control subjects. Specifically, the frequency of 47 recurrent CNVs previously associated with neurodevelopmental and neuropsychiatric illnesses in each cohort were compared. Next, CNV risk scores (CRSs), indices reflecting the dosage sensitivity for any gene across the genome that is encapsulated in a deletion or duplication separately, were compared between groups. RESULTS: The prevalence of recurrent CNVs was significantly higher in the EOP group than in the ASD (odds ratio=2.30) and control (odds ratio=5.06) groups. However, the difference between the EOP and ASD groups was attenuated when EOP participants with co-occurring ASD were excluded. CRS was significantly higher in the EOP group compared with the control group for both deletions (odds ratio=1.30) and duplications (odds ratio=1.09). In contrast, the EOP and ASD groups did not differ significantly in terms of CRS. CONCLUSIONS: Given the high frequency of recurrent CNVs in the EOP group and comparable CRSs in the EOP and ASD groups, the findings suggest that all children and adolescents with a psychotic diagnosis should undergo genetic screening, as is recommended in ASD.

RESUMO

This paper proposes a first step in deciding whether it is necessary to develop a cultural adaptation by comparing the cultural characteristics of an intervention with the same characteristics of a specific group. Larger cultural differences suggest a greater need to conduct a cultural adaptation. This recommendation stems from the cultural match theory (CMT) which, explains that therapeutic outcomes increase as interventions are more similar to the cultural characteristics of specific treatment groups. However, the CMT has rarely been tested, partly because strategies to effectively measure the cultural characteristics of an intervention are still lacking. This article addresses this gap by assessing two dimensions of the self-orientation relevant to cultural adaptations, namely, idiocentrism--the tendency to define oneself in isolation from others--and allocentrism--the tendency to define oneself in relationship to others--through a content analysis of guided imagery scripts. Two independent evaluators analyzed 123 guided imagery scripts (published during 1989-2008) using 6 theoretically derived categories to analyze idiocentrism versus allocentrism. Results indicated that idiocentric elements were 1.5 to 52.3 times more frequently used than were allocentric ones. The implications of these findings for the development of culturally adapted interventions are discussed.

RESUMO

Evidence-based treatments (EBTs) have been well studied in outpatient and research settings to address a myriad of mental health concerns. Research studies have found benefits and challenges when implementing these interventions. However, less is known about the implementation of EBTs in acute and intensive treatment settings such as inpatient psychiatric hospitalization (IPH) units, partial hospitalization programs (PHPs), or intensive outpatient programs (IOPs). As a result, the specific benefits and challenges of providing EBTs in these settings are less clear. For example, challenges of implementing EBTs in IPHs, PHPs, and IOPs can include working within a multi-disciplinary team setting and sustaining trained staff. The current article provides an overview of implementing EBTs in IPHs PHPs, and IOPs. Current PHP, IOP, and IPH models of implementing evidence-based interventions along with strategies for engaging stakeholders, program development and implementation, and measurement are reviewed. Further considerations for sustainability and practice consideration are also provided.

RESUMO

Nonsuicidal self-injury (NSSI) is a prevalent, concerning behavior among adolescents. Importantly, NSSI can serve a variety of functions. Some adolescents engage in NSSI to fulfill automatic or self-oriented functions (e.g., cutting to avoid internal negative states), whereas others engage in NSSI to serve social functions (e.g., cutting to communicate with others). This study tests whether self-reported reasons for engaging in NSSI, hereafter referred to as NSSI functions, predict NSSI thoughts and behaviors during and after hospitalization among adolescent psychiatric inpatients. Endorsement of both automatic and social NSSI functions, as well as positive and negative reinforcement subtypes, was assessed at hospital admission. Results showed that endorsement of overall automatic function predicted which adolescents engaged in NSSI behavior during hospitalization. Moreover, automatic and social functions showed distinct predictive patterns, such that automatic functions corresponded to greater likelihood of NSSI-related thoughts and behaviors whereas social functions mainly corresponded to reduced likelihood of NSSI-related outcomes. Of note, NSSI functions were less predictive of NSSI-related outcomes after hospital discharge. These findings suggest that identifying adolescent inpatients' reasons for NSSI engagement may meaningfully distinguish those at higher risk (and those at lower risk) of NSSI persistence during their hospital stay.

RESUMO

CONTEXT: Adolescent offspring of depressed parents are at markedly increased risk of developing depressive disorders. Although some smaller targeted prevention trials have found that depression risk can be reduced, these results have yet to be replicated and extended to large-scale, at-risk populations in different settings. OBJECTIVE: To determine the effects of a group cognitive behavioral (CB) prevention program compared with usual care in preventing the onset of depression. DESIGN, SETTING, AND PARTICIPANTS: A multicenter randomized controlled trial conducted in 4 US cities in which 316 adolescent (aged 13-17 years) offspring of parents with current or prior depressive disorders were recruited from August 2003 through February 2006. Adolescents had a past history of depression, current elevated but subdiagnostic depressive symptoms, or both. Assessments were conducted at baseline, after the 8-week intervention, and after the 6-month continuation phase. INTERVENTION: Adolescents were randomly assigned to the CB prevention program consisting of 8 weekly, 90-minute group sessions followed by 6 monthly continuation sessions or assigned to receive usual care alone. MAIN OUTCOME MEASURE: Rate and hazard ratio (HR) of a probable or definite depressive episode (ie, depressive symptom rating score of > or = 4) for at least 2 weeks as diagnosed by clinical interviewers. RESULTS: Through the postcontinuation session follow-up, the rate and HR of incident depressive episodes were lower for those in the CB prevention program than for those in usual care (21.4% vs 32.7%; HR, 0.63; 95% confidence interval [CI], 0.40-0.98). Adolescents in the CB prevention program also showed significantly greater improvement in self-reported depressive symptoms than those in usual care (coefficient, -1.1; z = -2.2; P = .03). Current parental depression at baseline moderated intervention effects (HR, 5.98; 95% CI, 2.29-15.58; P = .001). Among adolescents whose parents were not depressed at baseline, the CB prevention program was more effective in preventing onset of depression than usual care (11.7% vs 40.5%; HR, 0.24; 95% CI, 0.11-0.50), whereas for adolescents with a currently depressed parent, the CB prevention program was not more effective than usual care in preventing incident depression (31.2% vs 24.3%; HR, 1.43; 95% CI, 0.76-2.67). CONCLUSION: The CB prevention program had a significant prevention effect through the 9-month follow-up period based on both clinical diagnoses and self-reported depressive symptoms, but this effect was not evident for adolescents with a currently depressed parent.

RESUMO

INTRO: One of the more debilitating functional outcomes of schizophrenia-spectrum disorders is social impairment. Previous studies have identified impaired social functioning both in the prodromal phase of psychosis and after acute symptoms abate, suggesting that social impairment represents a core deficit in psychosis not directly linked to psychotic episodes or symptom severity. To date, research in this area has focused primarily on adult populations rather than children, and has not directly assessed social language in individuals across the psychosis continuum. METHODS: 81 youth ages 7-18 (N = 24 Typically Developing [TD], N = 36 Clinical High Risk [CHR], N = 21 Psychotic Disorder [PD]) were recruited. Youth participants were administered the Social Language Development Test (SLDT), and parent(s)/guardian(s) completed the Social Responsiveness Scale-II (SRS-II). RESULTS: Social language ability was not associated with social impairment. PD participants performed significantly worse on the SLDT than TD participants. CHR and PD participants were both rated as having experienced significantly greater social impairment than TD participants on every subscale of the SRS-II. DISCUSSION: Deficits in social language ability and social functioning are strong candidates for phenotypic markers of psychosis, and may be evident earlier in development than previous work has demonstrated. Additionally, the severity of social impairment did not differ between CHR and PD participants, further supporting that social cognitive deficits and social impairment, while related to symptom severity, are discrete deficits in individuals with and at risk for psychosis. These results highlight the importance of addressing social skills for individuals presenting in clinical settings with psychotic symptoms, including children.

RESUMO

Using self-harm Implicit Association Tests (IATs), we sought to test whether (1) suicidal adolescents show implicit identification with self-harm and whether (2) IATs are reliable and sensitive to psychiatric change and (3) predict future suicide attempts. We administered 6 self-harm IATs to 71 adolescents from a psychiatric inpatient unit and assessed suicidal behaviors at admission, discharge and 3 months after discharge. Results were in the expected direction for each IAT but not statistically significant. After aggregating trials across IATs, suicide attempters showed increased implicit identification with self-harm, compared with non-suicidal controls. IATs showed good reliability and sensitivity to psychiatric change but did not prospectively predict suicide attempts. Adolescent suicide attempters may have stronger implicit associations with self-harm than non-suicidal controls.

RESUMO

AIM: Previous research has demonstrated a strong association between early trauma exposure and the development of psychotic symptoms. However, few of these studies have included young adolescents and children. This study investigated rates and number of potentially traumatic experiences (PTEs) among typically developing youth (TD; n = 21), youth at clinical high risk for psychosis (CHR; n = 38), and youth with a psychotic disorder (PD; n = 28) between 7 and 18 years of age. CHR participants were further evaluated to determine whether a history of PTEs was associated with prodromal symptom severity. METHODS: Study group inclusion was determined by structured interviews. Trauma history was assessed using the post-traumatic stress disorder module of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. CHR participants with vs without a history of PTEs were compared on severity of prodromal symptoms. RESULTS: CHR and PD participants reported significantly higher rates and numbers of PTEs than TD participants. Contrary to expectations and prior research, CHR participants with vs without a history of PTEs did not differ in prodromal symptom severity. Explanations and implications for the findings are discussed. CONCLUSIONS: These findings suggest that the relationship between trauma and the development of psychotic symptoms extends to children and adolescents as young as 7 years of age. This study underscores the importance of screening for trauma exposure among youth seeking treatment for psychotic symptoms.
