Remote assessment of ADHD in children and adolescents: recommendations from the European ADHD Guidelines Group following the clinical experience during the COVID-19 pandemic.

The COVID-19 pandemic led ADHD services to modify the clinical practice to reduce in-person contact as much as possible to minimise viral spread. This had far-reaching effects on day-to-day clinical practice as remote assessments were widely adopted. Despite the attenuation of the acute threat from COVID, many clinical services are retaining some remote practices. The lack of clear evidence-based guidance about the most appropriate way to conduct remote assessments meant that these changes were typically implemented in a localised, ad hoc, and un-coordinated way. Here, the European ADHD Guidelines Group (EAGG) discusses the strengths and weaknesses of remote assessment methods of children and adolescents with ADHD in a narrative review based on available data and expert opinions to highlight key recommendations for future studies and clinical practice. We conclude that going forward, despite remote working in clinical services functioning adequately during the pandemic, all required components of ADHD assessment should still be completed following national/international guidelines; however, the process may need adaptation. Social restrictions, including changes in education provision, can either mask or exacerbate features associated with ADHD and therefore assessment should carefully chart symptom profile and impairment prior to, as well as during an ongoing pandemic. While remote assessments are valuable in allowing clinical services to continue despite restrictions and may have benefits for routine care in the post-pandemic world, particular attention must be paid to those who may be at high risk but not be able to use/access remote technologies and prioritize these groups for conventional face-to-face assessments.

Validation of a Spanish-language version of the ADHD Rating Scale IV in a Spanish sample. / Validación de la versión en español de la escala de evaluación del trastorno por déficit de atención e hiperactividad (ADHD-RS-IV.es) en una muestra española.

OBJECTIVES: The purpose of this study is to validate a Spanish-language version of the 18-item ADHD Rating Scale-IV (ADHD-RS-IV.es) in a Spanish sample. METHODS: From a total sample of 652 children and adolescents aged 6 to 17 years (mean age was 11.14±3.27), we included 518 who met the DSM-IV-TR criteria for ADHD and 134 healthy controls. To evaluate the factorial structure, validity, and reliability of the scale, we performed a confirmatory factor analysis (CFA) using structural equation modelling on a polychoric correlation matrix and maximum likelihood estimation. The scale's discriminant validity and predictive value were estimated using ROC (receiver operating characteristics) curve analysis. RESULTS: Both the full scale and the subscales of the Spanish-language version of the ADHD-RS-IV showed good internal consistency. Cronbach's alpha was 0.94 for the full scale and ≥ 0.90 for the subscales, and ordinal alpha was 0.95 and ≥ 0.90, respectively. CFA showed that a two-factor model (inattention and hyperactivity/impulsivity) provided the best fit for the data. ADHD-RS-IV.es offered good discriminant ability to distinguish between patients with ADHD and controls (AUC=0.97). CONCLUSIONS: The two-factor structure of the Spanish-language version of the ADHD-RS-IV (ADHD-RS-IV.es) is consistent with those of the DSM-IV-TR and DSM-5 as well as with the model proposed by the author of the original scale. Furthermore, it has good discriminant ability. ADHD-RS-IV.es is therefore a valid and reliable tool for determining presence and severity of ADHD symptoms in the Spanish population.

Perseverative error in schizophrenia: correlation with cortical blood flow by SPECT.

INTRODUCTION: Perseverative error (PE) is a core symptom of schizophrenia which has been proposed as a phenotypic marker of the illness. Moreover, hypofrontality observed in functional neuroimaging studies while executing a cognitive task has also been suggested as a characteristic sign of schizophrenia. We propose combining symptom and sign to demonstrate the existence of a regional cortical blood flow (RCBF) pattern associated to PE that might constitute a biological marker of schizophrenia. MATERIAL AND METHOD: We used Single Photon Emission Computerized Tomography (SPECT), to study the RCBF associated to PE and to correct response (CR), during the execution of the Wisconsin Card Sorting Test (WCST), of 18 patients with schizophrenia and 13 controls. We focused on five well-defined bilateral brain regions, using the RCBF of the same regions at rest as a baseline. RESULTS: Patients made more PE than controls in the WCST. Among patients, we observed a correlation between PEs and right occipital RCBF. Among controls, we found a negative correlation between PEs and left temporal cortex RCBF and a positive correlation between CRs and left frontobasal and overall left frontal cortexes RCBF. CONCLUSIONS: The severity of PE is associated to higher right parietal-occipital activity in patients with schizophrenia. CR in the WCST are associated to higher left frontal activity in controls but not in patients. Probably, there is a RCBF redistribution pattern related to the typical perseveration of schizophrenia which might constitute a phenotypic marker of the illness observable by functional neuroimaging techniques.

Prior stimulant treatment in adolescents with bipolar disorder: association with age at onset.

OBJECTIVES: To compare demographic and clinical characteristics between bipolar adolescents with and without a history of stimulant treatment, we hypothesized that adolescents treated with stimulants would have an earlier age at onset of bipolar disorder, independent of co-occurring attention-deficit-hyperactivity disorder (ADHD). METHOD: Thirty-four adolescents hospitalized with mania were assessed using the Washington University at St Louis Kiddie Schedule for Affective Disorders and Schizophrenia (WASH-U-KSADS). We systematically evaluated age at onset of bipolar disorder and pharmacological treatment history. RESULTS: Bipolar adolescents with a history of stimulant exposure prior to the onset of bipolar disorder had an earlier age at onset of bipolar disorder than those without prior stimulant exposure. Additionally, bipolar adolescents treated with at least two stimulant medications had a younger age at onset compared with those who were treated with one stimulant. There was no difference in age at onset of bipolar disorder between bipolar adolescents with and without ADHD. CONCLUSIONS: Our results suggest that stimulant treatment, independent of ADHD, is associated with younger age at onset of bipolar disorder. A behavioral sensitization model is proposed to explain our findings. There are several limitations to our study including the small sample size, the retrospective assessment of stimulant exposure and age at onset of bipolar disorder, and the inclusion of only hospitalized patients, who may be more likely to present with a severe illness. Nonetheless, future prospective longitudinal investigations that systematically assess the effects of stimulant medications in children with or at genetic risk for bipolar disorder are warranted.

Effects of race on psychiatric diagnosis of hospitalized adolescents: a retrospective chart review.

BACKGROUND: Several studies have reported that patient ethnicity influences psychiatric diagnosis, although this has only been examined in adolescents in two prior studies. One study was based on an outpatient sample and the other was a retrospective study involving a relatively small sample of inpatients. We hypothesized that, as reported in adults, African American adolescents would be diagnosed with schizophrenic spectrum disorders more frequently than Caucasians, and Caucasians correspondingly would receive more affective disorders diagnoses. METHODS: We retrospectively examined the charts of all adolescents (ages 12-18 years) admitted to the Adolescent Psychiatry Unit at Cincinnati Children's Hospital Medical Center (n = 1,001) between July 1995 and June 1998 for demographic information and discharge diagnoses. We used insurance status as a proxy for socioeconomic status. RESULTS: African American males were more commonly diagnosed with schizophrenic spectrum disorders than were African American women, Caucasian women, and Caucasian men. There were significantly more African Americans diagnosed with conduct disorder than Caucasians. In contrast, Caucasians were diagnosed with alcohol use disorders and major depression more often. CONCLUSIONS: Patient race and sex may influence clinical psychiatric diagnoses of hospitalized adolescents. Further investigations using structured interviews are necessary to determine whether the disparity in clinical diagnosis is secondary to actual gender and racial differences in the rates of illnesses in hospitalized adolescents or due to other factors that may contribute to diagnostic practices.

Diagnostic characteristics of 93 cases of a prepubertal and early adolescent bipolar disorder phenotype by gender, puberty and comorbid attention deficit hyperactivity disorder.

OBJECTIVE: Etiopathogenetic and treatment studies require homogeneous phenotypes. Therefore, effects of gender, puberty, and comorbid attention deficit hyperactivity disorder (ADHD) on DSM-IV mania criteria and other characteristics of a prepubertal and early adolescent bipolar disorder (PEA-BP) phenotype were investigated. METHOD: Consecutively ascertained PEA-BP (with or without comorbid ADHD) outpatients (n = 93) were blindly assessed by research nurses with comprehensive instruments given to mothers and children separately, consensus conferences, and offsite blind best estimates of both diagnoses and mania items. To fit the study phenotype, subjects needed to have current DSM-IV mania or hypomania with elated mood and/or grandiosity as one criterion and to be definite cases by severity ratings. RESULTS: Subjects were aged 10.9 +/- 2.6 years, had current episode length of 3.6 +/- 2.5 years, and had early age of onset at 7.3 +/- 3.5 years. No significant differences were found by gender, puberty, or comorbid ADHD on rates of mania criteria (e.g., elation, grandiosity, racing thoughts), mixed mania, psychosis, rapid cycling, suicidality, or comorbid oppositional defiant disorder (ODD), with few exceptions. Subjects with comorbid ADHD were more likely to be younger and male. Pubertal subjects had higher rates of hypersexuality. CONCLUSIONS: These findings support that the PEA-BP phenotype is homogeneous except for differences (hyperactivity, hypersexuality) that mirror normal development.

Six-month stability and outcome of a prepubertal and early adolescent bipolar disorder phenotype.

OBJECTIVE: Six-month follow-up data are provided on a prepubertal and early adolescent bipolar disorder phenotype (PEA-BP). Stabilities were defined as continuous presence of PEA-BP and of individual mania criteria between baseline and 6 months. METHOD: Baseline and 6-month assessments of consecutively ascertained PEA-BP outpatients (n = 91) included comprehensive instruments given to mothers and children, separately, by research nurses; consensus conferences; and offsite blind best estimates of both diagnoses and mania items. To fit the study phenotype, subjects needed to have current DSM-IV mania or hypomania with elated mood and/or grandiosity as one mania criterion and to be definite cases by severity ratings. RESULTS: Of the 93 baseline subjects, 91 completed the 6-month assessment, for a retention rate of 97.8%. Baseline age was 10.9 +/- 2.7 years, and age of onset of current episode was 7.3 +/- 3.5 years. At 6 months, 85.7% still had full criteria and severity for mania or hypomania, and only 14.3% had recovered. Six-month stabilities of elated mood and grandiosity were high. Cox modeling and logistic regression did not show any significant effect of multiple covariates (e.g., gender, puberty, psychosis, mixed mania, rapid cycling, or naturalistic treatment). CONCLUSIONS: These longitudinal stability findings provide validation of a PEA-BP phenotype. Poor outcome was consistent with similarity of PEA-BP baseline characteristics to those of treatment-resistant adult-onset mania.

Placebo-controlled trial of sertraline in the treatment of binge eating disorder.

OBJECTIVE: The authors' goal was to assess the efficacy of sertraline in the treatment of binge eating disorder. METHOD: Thirty-four outpatients with DSM-IV binge eating disorder were randomly assigned to receive either sertraline (N=18) or placebo (N=16) in a 6-week, double-blind, flexible-dose (50-200 mg) study. Except for response level, outcome measures were analyzed by random regression methods, with treatment-by-time interaction as the effect measure. RESULTS: Compared with placebo, sertraline was associated with a significantly greater rate of reduction in the frequency of binges, clinical global severity, and body mass index as well as a significantly greater rate of increase in clinical global improvement. Patients receiving sertraline who completed the study demonstrated a higher level of response, although the effect was not significant. CONCLUSIONS: In a 6-week trial, sertraline was effective and well tolerated in the treatment of binge eating disorder.

Antipsychotics in the treatment of mood disorders and risk of tardive dyskinesia.

Psychosis occurs commonly in patients with mood disorders and has traditionally been treated with typical antipsychotics. Exposure to typical antipsychotics poses a risk for the emergence of tardive dyskinesia. Atypical antipsychotics may have advantages over typical agents in the treatment of patients with mood disorders complicated by psychotic features. The studies of typical and atypical antipsychotics in the treatment of mood disorders were reviewed. Similarly, studies regarding the risk of tardive dyskinesia from typical and atypical agents in patients with mood disorders were surveyed. Typical and atypical antipsychotics appear to be comparably effective in the treatment of acute mania. Limited data regarding these medications in psychotic depression are available. Advantages of atypical antipsychotics include, for most agents, minimal extrapyramidal and prolactin effects, inherent thymoleptic activity, and lower rates of tardive dyskinesia. Atypical antipsychotics appear to have a number of advantages over typical agents in the treatment of patients with psychotic mood disorders.

Olanzapine in the treatment of adolescent acute mania: a report of seven cases.

BACKGROUND: Clozapine may be effective in adults and adolescents with treatment-resistant bipolar disorder. Olanzapine has a receptor affinity profile similar to that of clozapine. METHODS: The responses of seven consecutive adolescents (ages 12-17) with DSM-IV bipolar disorder, manic episode, treated with olanzapine were evaluated. Response to olanzapine was rated as marked, moderate, minimal, none or worse. RESULTS: Five (71%) adolescents showed a marked or moderate response. The mean+/-SD olanzapine dose was 0.146+/-0.086 mg/kg/day (11+/-6 mg/day). CONCLUSION: Olanzapine may have antimanic effects in some adolescents with acute mania. Controlled studies of olanzapine in adolescent bipolar disorder appear to be warranted.

Psychiatric features of 36 men convicted of sexual offenses.

BACKGROUND: To increase understanding of the relationship between sexual violence and mental illness, the authors assessed the legal histories and psychiatric features of 36 males convicted of sexual offenses. METHOD: Thirty-six consecutive male sex offenders admitted from prison, jail, or probation to a residential treatment facility received structured clinical interviews for DSM-IV Axis I and II disorders. The participants' legal histories, histories of sexual and physical abuse, and family histories of psychiatric disorders were also assessed. RESULTS: The participants' mean +/- SD age was 33+/-8 years. They had been convicted a mean of 1.8+/-1.4 times (range, 1-9 times) for sexual offenses and incarcerated a mean of 8+/-6 years (range, 0-22 years). Participants displayed high rates of lifetime DSM-IV Axis I disorders: 30 (83%) had a substance use disorder; 21 (58%), a paraphilia; 22 (61%), a mood disorder (13 [36%] with a bipolar disorder); 14 (39%), an impulse control disorder; 13 (36%), an anxiety disorder; and 6 (17%), an eating disorder. Participants also displayed high rates of Axis II disorders, with 26 (72%) meeting DSM-IV criteria for antisocial personality disorder. In addition, subjects reported experiencing high rates of sexual (but not physical) abuse and high rates of Axis I disorders, especially substance use and mood disorders, in their first-degree relatives. Compared with subjects without paraphilias, subjects with paraphilias displayed statistically significantly higher rates of mood, anxiety, and eating disorders, as well as significantly higher rates of childhood sexual abuse. CONCLUSION: Recognition and treatment of major psychiatric disorders among sex offenders may increase chances for successful rehabilitation, reduce recidivism and public victimization, and produce significant public health and economic benefits. More studies in this area appear warranted to search for more effective interventions for this severe public health problem.

The psychiatric diagnoses of twenty-two adolescents who have sexually molested other children.

The purpose of this study was to assess the prevalence of specific psychiatric disorders in adolescents who have sexually molested other children. Twenty-two adolescent males (aged 13 to 17 years) who sexually molested a child at least once were evaluated with structured clinical interviews for DSM-III-R axis I disorders. All subjects met lifetime DSM-III-R criteria for pedophilia (with the exception of the age requirement), 21 (95%) for two or more paraphilias, 18 (82%) for a mood disorder (12 [55%] for a bipolar disorder), 12 (55%) for an anxiety disorder, 11 (50%) for a substance use disorder, and 12 (55%) for an impulse-control disorder. Also, 12 (71%) of 17 subjects were diagnosed with attention-deficit/hyperactivity disorder, and 16 (94%) with conduct disorder. We conclude that some adolescent child molesters may have pedophilia or other paraphilias. Other axis I disorders with impulsive features, especially conduct, attention-deficit/hyperactivity, bipolar, and substance use disorders, may also be found in these adolescents.

Traumatic brain injury in individuals convicted of sexual offenses with and without bipolar disorder.

The authors examined the occurrence of traumatic brain injury (TBI) in individuals convicted of sexual offenses with and without bipolar disorder and a comparison group of patients with bipolar disorder without a history of sexual offending behaviors. Individuals convicted of sexual offenses and diagnosed with bipolar disorder had greater rates of brain injury resulting from head trauma than individuals convicted of sexual offenses without bipolar disorder and comparison patients with bipolar disorder. TBI predated the first sexual offense and/or the onset of bipolar disorder in most subjects.
