RESUMO
This study aimed to analyze body size estimates of others by patients with anorexia nervosa (AN) and to identify any differences with the perception of their own body size. Adolescent females (age, 13-17 years) were enrolled into AN (n = 30) and control(n = 23) groups. The Subjective Body Dimensions Apparatus (SBDA) was used to evaluate body size estimates for oneself (self-estimation) and others (other-estimation). Participants also completed questionnaires assessing eating disorders and depressive symptoms. The AN and control groups scored significantly higher in self-estimation than in other-estimation. However, the AN group showed higher self-estimation scores than the control group for all the body parts and for the global silhouette (p < .001). Patients with more severe eating disorder symptomatology showed more distorted self-estimation (p < .05). No statistically significant differences were found in the other-estimation scores between the groups (p = .714), indicating that AN and control patients estimate the body sizes of others similarly. Eating disorder symptomatology correlates with self-estimation scores but not with other-estimation scores in adolescents with AN. No correlations existed between clinical symptomatology and other-estimation.

Nutrition is fundamental for brain development, but relatively little is known about water-soluble vitamin (WSV) levels and the effect of supplementation on psychiatry symptoms in children and adolescents (CAD) with psychiatric disorders. Our team systematically reviewed all studies concerning WSV abnormalities or supplementation in CAD with any psychiatric disorder. We searched for original studies published between 1990 and 15/05/2020 which were not based on retrospective chart review and which included WSV blood level measurements or investigated the effect of WSV supplementation on psychiatric symptoms in psychiatric patients aged 18 or under. Forty-two articles were included, 69% of which (N = 29) examined Autism Spectrum Disorders (ASD), with most of these assessing folate or vitamin B12 supplementation (N = 22, 75.9% of ASD studies). Meta-analyses showed significantly lower vitamin B12 levels in ASD and ADHD patients vs. healthy controls (HC), while folate levels were higher in ADHD patients vs. HC. Most of the studies (9/10, 90%) showed a decrease in symptoms as measured by clinical scales after supplementation. There was significant heterogeneity between the studies, however many found different types of vitamin abnormalities in CAD with psychiatric disorders.

Anorexia nervosa (AN) typically emerges in adolescence. The cortico-striatal system (CSTS) and the default mode network (DMN) are brain circuits with a crucial development during this period. These circuits underlie cognitive functions that are impaired in AN, such as cognitive flexibility and inhibition, among others. Little is known about their involvement in adolescent AN and how weight and symptom improvement might modulate potential alterations in these circuits. Forty-seven adolescent females (30 AN, 17 healthy control) were clinically/neuropsychologically evaluated and scanned during a 3T-MRI resting-state session on two occasions, before and after a 6-month multidisciplinary treatment of the AN patients. Baseline and baseline-to-follow-up between-group differences in CSTS and DMN resting-state connectivity were evaluated, as well as their association with clinical/neuropsychological variables. Increased connectivity between the left dorsal putamen and the left precuneus was found in AN at baseline. At follow-up, body mass index and clinical symptoms had improved in the AN group. An interaction effect was found in the connectivity between the right dorsal caudate to right mid-anterior insular cortex, with lower baseline AN connectivity that improved at follow-up; this improvement was weakly associated with changes in neuropsychological (Stroop test) performance. These results support the presence of CSTS connectivity alterations in adolescents with AN, which improve with weight and symptom improvement. In addition, at the level of caudate-insula connectivity, they might be associated with inhibitory processing performance. Alterations in CSTS pathways might be involved in AN from the early stages of the disorder.

Disruptive behavior during childhood and adolescence is heterogeneous and associated with several psychiatric disorders. The identification of more homogeneous subgroups might help identify different underlying pathways and tailor treatment strategies. Children and adolescents (aged 8-18) with disruptive behaviors (N = 121) and healthy controls (N = 100) were included in a European multi-center cognition and brain imaging study. They were assessed via a battery of standardized semi-structured interviews and questionnaires. K-means cluster-model analysis was carried out to identify subgroups within the group with disruptive behaviors, based on clinical symptom profiles, callous-unemotional (CU) traits, and proactive and reactive aggression. The resulting subgroups were then compared to healthy controls with regard to these clinical variables. Three distinct subgroups were found within the group with disruptive behaviors. The High CU Traits subgroup presented elevated scores for CU traits, proactive aggression and conduct disorder (CD) symptoms, as well as a higher proportion of comorbidities (CD + oppositional defiant disorder + attention deficit hyperactivity disorder (ADHD). The ADHD and Affective Dysregulation subgroup showed elevated scores for internalizing and ADHD symptoms, as well as a higher proportion of females. The Low Severity subgroup had relatively low levels of psychopathology and aggressive behavior compared to the other two subgroups. The High CU Traits subgroup displayed more antisocial behaviors than the Low Severity subgroup, but did not differ when compared to the ADHD and Affective Dysregulation subgroup. All three subgroups differed significantly from the healthy controls in all the variables analyzed. The present study extends previous findings on subgrouping children and adolescents with disruptive behaviors using a multidimensional approach and describes levels of anxiety, affective problems, ADHD, proactive aggression and CU traits as key factors that differentiate conclusively between subgroups.

OBJECTIVE: The objective of the present study is to evaluate cortical thickness (CT) abnormalities using FreeSurfer in adult subjects who had an onset of anorexia nervosa during their adolescence some 20 years previously, and to compare them with control subjects. METHODS: Fifty-four participants, including 26 women who were diagnosed and treated for AN during adolescence some 20 years previously and 28 healthy women of similar age and geographical area were assessed using structured interviews and MRI scans. Prior AN subjects were divided into two groups depending on their current eating disorder status (recovered or not recovered from any eating disorder). In all subjects, CT was measured using FreeSurfer. RESULTS: A significantly lower CT was observed in the eating disorder group than in the control group in the right post-central gyrus and the lateral occipital cortex. The recovered eating disorder group only had lower CT in the post-central gyrus. Within all subjects with prior AN, no correlations were found between lower CT in these areas and clinical variables. DISCUSSION: CT is reduced some 20 years after diagnosis of AN especially in the parietal and precentral areas, even in subjects without any current ED diagnosis.

PURPOSE: The many studies examining the relationship between anorexia nervosa (AN) and personality abnormalities have observed high comorbidity. However, no definitive studies to date have established whether there is a causal connection or whether it is a complication. The current study aimed to explore the nature of the relationship between personality disorder (PD) traits, obsessionality and perfectionism, using a study design that allows the testing of some comorbidity models. METHODS: Twenty-nine women were recruited from a group of former AN patients treated during their adolescence in a specialized unit around 20 years before the time of this study. They were divided into two groups according to the current presence of eating disorder (ED) symptoms (current-ED, n = 11; recovered, n = 18). Both groups were compared to a matched control group (n = 29) regarding current PD traits, obsessive beliefs and perfectionism. RESULTS: Borderline PD traits, most cluster C PD traits and overestimation of threat were more common in the current-ED group than in the control and recovered groups. Obsessive-compulsive PD traits, intolerance of uncertainty, and perfectionism were also significantly more prevalent in the current-ED group compared to controls but did not reach significance when compared to the recovered group. No significant differences were found between the recovered and control groups. CONCLUSION: Our results mostly support the personality abnormalities observed as a transient effect related to the presence of ED psychopathology in patients with adolescent-onset AN. LEVEL OF EVIDENCE: Level III, case-control analytic studies.

To compare a sample of adolescents with schizophrenia spectrum disorders (SSD) treated with either ECT or antipsychotics (AP) alone at long-term follow-up. Patients diagnosed with SSD (n = 21) treated with ECT due to resistance to AP or catatonia under the age of 18 years (ECT group), were compared to a randomly selected group of patients with SSD treated only with AP (non-ECT group) (n = 21) and matched for age, gender, diagnosis and duration of illness. Baseline data were gathered retrospectively from medical records. Subjects were assessed at follow-up (mean of follow-up period = 5.5 years; range 2-9 years) using several clinical scales such as the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression Scale (CGI) and the Global Assessment of Functioning (GAF). Improvement in PANSS positive, negative, general, total and CGI and GAF scores between baseline and follow-up assessment did not differ significantly between groups. At follow-up, no differences were observed for the PANSS negative, CGI and GAF scores between groups, but patients in the ECT group still had higher PANSS total, positive and general scores. ECT treatment followed by AP medication in treatment-resistant SSD or catatonia is at least as effective in the long term as AP alone in non-resistant patients.

OBJECTIVES: Adequate quantity and quality of the DNA isolated from saliva samples are crucial for ensuring successful genotyping rates in genetic studies. However, there is little information about these issues when saliva samples are collected from children. The objectives of this study were to assess whether there are differences in DNA quality or quantity isolated from saliva samples of children at different ages and adolescents compared to adults and, if so, to establish a modified protocol to improve and standardize DNA isolation from saliva samples of children. METHODS: Saliva samples were collected with Oragene DNA Sample Collection Kit from 41 healthy subjects including children of different ages, adolescents, and adults. Quantity and quality of isolated DNA were determined spectrophotometrically. RESULTS: DNA concentration and age were positively correlated (r = 0.676, P < 0.001). A high percentage of samples from children below 12 years yielded DNA concentrations <100 ng/µL and DNA quality a260/a280 ratios of <1.8. Modifying the standard DNA isolation method raised DNA quantity and quality in these critical samples. CONCLUSIONS: Age determines, at least in part, the high variability observed in the concentration of DNA isolated from saliva samples. This fact should be taken into account for a better standardization of the DNA isolation to ensure DNA banking in large-scale genetic studies involving children.

In children and adolescents with conduct disorder (CD), pharmacotherapy is considered when non-pharmacological interventions do not improve symptoms and functional impairment. Risperidone, a second-generation antipsychotic is increasingly prescribed off-label in this indication, but its efficacy and tolerability is poorly studied in CD, especially in young people with normal intelligence. The Paediatric European Risperidone Studies (PERS) include a series of trials to assess short-term efficacy, tolerability and maintenance effects of risperidone in children and adolescents with CD and normal intelligence as well as long-term tolerability in a 2-year pharmacovigilance. In addition to its core studies, secondary PERS analyses will examine moderators of drug effects. As PERS is a large-scale academic project involving a collaborative network of expert centres from different countries, it is expected that results will lead to strengthen the evidence base for the use of risperidone in CD and improve standards of care. Challenging issues faced by the PERS consortium are described to facilitate future developments in paediatric neuropsychopharmacology.

Delusional thinking is a key symptom of first-episode psychosis (FEP), but it has also been studied in obsessive-compulsive disorder (OCD) and anorexia nervosa (AN). This study aimed to analyze the psychometric properties of the Brown Assessment of Beliefs Scale (BABS) in a sample of adolescents diagnosed with a FEP, AN, or OCD, and to compare delusional thinking among the three samples. The sample comprised 60 patients in three groups of 20 diagnosed with OCD, AN, or FEP. Participants underwent assessment by diagnostic interview, the BABS scale, and a measure of depressive symptomatology. Specific instruments were also used to assess the main symptomatology of each disorder. The BABS had good internal consistency, and high validity and reliability. The OCD group scored significantly lower than the other two groups in all scale items except for items 4 (fixation of ideas), 6 (insight), and 7 (delusions of reference). A significant difference only existed between the AN and FEP groups for item 7 (delusions of reference). The BABS scale is a valid and reliable tool for assessing delusionality in adolescents diagnosed with OCD, AN, or FEP, with evidence of marked differences between the disorders. Assessing these symptoms could influence management, helping to improve treatment adherence and prognosis.

OBJECTIVES: As part of the 'Suicidality: Treatment Occurring in Paediatrics (STOP)' study, we developed and performed psychometric validation of an electronic-clinical-outcome-assessment (eCOA), which included a patient-reported-outcome (ePRO), an observer-rated-outcome (eObsRO) for parents/carers and a clinician-reported-outcome (eClinRO) that allows identification and monitoring of medication-related suicidality (MRS) in adolescents. DESIGN: STOP: Prospective study: A two phase validation study to assess the impact of medication on suicidal ideations. SETTING: Six participating countries: Netherlands, UK, Germany, France, Spain and Italy that were part of the Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 261411. PARTICIPANTS: Cohort 1 consisted of 41 adolescent-completions, 50 parent-completions and 56 clinician-completions. Cohort 2 consisted of 244 adolescent-completions, 198 parent-completions and 240 clinician-completions from across the six countries. The scale was administered only to participants who have screened positive for the STOP-Suicidality Assessment Scale (STOP-SAS). RESULTS: A total of 24 items for the development of the STOP-Medication Suicidality Side Effects Scale (STOP-MS3) were identified and three versions (for patients, parents and clinicians) of the STOP-MS3 were developed and validated in two separate study cohorts comprising of adolescents, their parents and clinicians. Cronbach's α coefficients were above 0.85 for all domains. The inter-rater reliability of the STOP-MS3 was good and significant for the adolescent (ePRO), clinician (eClinRO) (r=0.613), parent (eObsRO) versions of the scale (r=0.394) and parent and clinician (r=0.347). Exploratory factor analysis identified a 3-factor model across 24 items for the adolescent and parent version of the scale: (1) Emotional Dysregulation, (2) Somatic Dysregulation and (3) Behavioural Dysregulation. For the clinician version, a 4-factor model defined the scale structure: (1) Somatic Dysregulation, (2) Emotional Dysregulation, (3) Behavioural Dysregulation and (4) Mood Dysregulation. CONCLUSION: These findings suggest that the STOP-MS3 scale, a web-based eCOA, allows identification and monitoring of MRS in the adolescent population and shows good reliability and validity.

OBJECTIVE: To evaluate the safety and effectiveness of the combination of electroconvulsive therapy (ECT) and clozapine compared to ECT with other antipsychotics or benzodiazepines in a sample of adolescents diagnosed with schizophrenia spectrum disorders. METHODS: Data regarding 28 adolescent subjects aged 13 to 18 with diagnoses of schizophrenia spectrum disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and treated with ECT were retrospectively collected. Twelve subjects were also treated with clozapine and 16 with other antipsychotics or benzodiazepines during ECT course and follow-up. Electroconvulsive therapy parameters and adverse effects were assessed using a systematic protocol. Positive and Negative Syndrome Scale and Clinical Global Impression scores before ECT and after acute ECT, and rate of rehospitalization during 1-year follow-up were used to assess effectiveness. Response was defined as a 20% decrease in Positive and Negative Syndrome Scale scores. RESULTS: No differences were observed in the mean charge needed to induce seizure and electroencephalographic duration, but there was a slight difference in the current used. The nonclozapine group showed greater restlessness and agitation, although no differences were found in other adverse effects. The percentage of responders was similar: 66.7% in the clozapine group and 68.8% in the nonclozapine group. However, the rate of rehospitalization was lower in the patients treated with clozapine during 1-year follow-up (7.1%) compared to that of the nonclozapine group (58.3%) (P = 0.009). CONCLUSIONS: The main findings of this study were that combining ECT with clozapine, compared to ECT with other antipsychotics or benzodiazepines, was safe and that both treatments were equally effective. Charges needed to induce seizure were similar in both groups. Patients treated with clozapine during 1-year follow-up had a lower rate of rehospitalization.

BACKGROUND: The COVID-19 pandemic, associated with confinement and social isolation, seems to have impacted the course of many mental disorders in children and adolescents. An increase in hospital admission rates for juvenile anorexia nervosa (AN) has been documented in many regions of the world. However, data from Europe are scarce. METHODS: We asked clinicians in specialized eating disorder units in hospitals of maximum care in France, Germany, Italy, Spain, Sweden, and the Netherlands to report on (i) overall (inpatient and outpatient) and (ii) inpatient admission rates for adolescents with AN during 2019 and 2020. Additionally, a modified version of the COVID Isolation Eating Scale (CIES) was used to assess the child and adolescent psychiatrists' estimations of a possible increase in symptom severity in children and adolescents with AN during the COVID-19 pandemic and to (iii) inquire about the contributing factors perceived by the caring professionals. RESULTS: Four out of six representatives of European hospitals described a higher rate of overall admissions during the pandemic. Three hospitals out of six reported an increase in inpatient admissions, and two centres had constant high numbers of admissions of both outpatients and inpatients. The clinicians perceived a higher symptom severity in 2020 than in 2019, especially involving more frequent use of social media, longer duration of exercising, and more restrictive eating. They supposed an increase in social media consumption, a perceived "loss of control", and a lack of in-person assessments and weight controls as the main contributing factors for the deterioration in AN numbers and symptomatology. CONCLUSIONS: The COVID-19 pandemic seems to have had a deep impact on symptom severity in AN, which is mirrored by a large increase in admission rates across Europe. An increase in exercise, social media consumption, a perceived "loss of control", and a lack of face-to-face health care seem to have contributed to this development. Further investigation is required to identify which factors may lead to the increase in incidence and deterioration of childhood and adolescent AN. Possible preventive means for the future could include educating paediatricians and health care workers about AN, regular weight assessment, and home-based treatments.
RESUMO
OBJECTIVE: To assess the outcome of adolescents with anorexia nervosa (AN) about 20 years after first treatment. METHODS: Sixty-two women diagnosed with AN during adolescence were invited to participate. Of these 62 patients, 38 agreed to participate and were assessed with a battery of questionnaires and interviews. A control group of 30 women of similar age was also assessed. RESULTS: Of the patients who completed the full assessment, 13 (34%) presented some degree of eating disorder (ED) at follow-up (10 (26%) met full Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for an ED and 3 (8%) showed partial remission of an ED). The remaining 25 (66%) patients had fully recovered from AN. The duration of untreated illness before admission was significantly associated with an increased risk of a current ED (odds ratio (OR) = 3.334 (1.3-8.7); p = .014). Of the patients who had recovered totally from their ED, 24% showed another psychiatric disorder. This percentage rose to 70% in patients with a current ED. CONCLUSION: Sixty-six percent of adolescents who completed the assessment achieved remission of their AN. Comorbidity was more common in the current ED group. The variable that best predicted complete remission was the number of years without treatment, showing the importance of detection and early intervention.

BACKGROUND AND OBJECTIVES: Observational studies have reported earlier onset of psychosis in schizophrenic patients with a history of cannabis use. Earlier age of onset of schizophrenia has been associated with a poorer outcome. We aimed to examine whether cannabis use determined an earlier onset of schizophrenia in a sample of first episode patients, in an area with one of Europe's highest rates of cannabis use. METHODS: 116 subjects with first episode psychosis and subsequent diagnosis of schizophrenia (after a 12-month follow-up) were included Age at first antipsychotic treatment (A1T) was used as proxy for age of psychosis onset, and acted as dependent variable for the statistical analysis. Cannabis use was evaluated retrospectively, and divided into three groups according to peak frequency (never, sporadic/frequent, daily). RESULTS: 46 (39.7%) subjects had never used cannabis, 23 (19.9%) had done so sporadically/frequently, and 47 (40.5%) daily. A1T differed between the three groups (mean, in years and [SD]: 27.0 [4.94]; 25.7 [4.44] and 24.5 [4.36]; p=0.033) and diminished as cannabis use increased (linear tendency; p=0.009). Post-hoc analysis showed that cannabis use (irrespective of frequency) was significantly associated with decrease in A1T (p=0.033), as shown by the first contrast [1 -1/2 -1/2]. Post-hoc contrast showed that cannabis users had a significantly lower age of onset of psychosis (mean decrease, in years: 1.93; CI (confidence interval) 95%: 0.17-3.70; p=0.033). CONCLUSIONS: Cannabis use was significantly associated with a decrease in age of onset of schizophrenia. Age of onset of the disease correlated with frequency of cannabis use.

OBJECTIVE: The aim of the study was to compare two dimensions of perfectionism, namely self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP), in adolescents with anorexia nervosa (AN) or obsessive-compulsive disorder (OCD) and in healthy controls. A further objective was to investigate the influence of perfectionism dimensions on obsessive-compulsive, depressive, and eating symptomatology. METHODS: A total of 79 adolescents with AN, 32 with OCD, and 74 healthy controls were recruited. The Child and Adolescent Perfectionism Scale (CAPS) was used to assess SOP and SPP. Measures of depression, obsessive-compulsive and eating symptomatology were administered. RESULTS: The AN group scored higher on SOP than did both the OCD group (p < 0.001) and controls (p < 0.001). In the AN group, SOP accounted for significant variance in scores on the obsessive (p < 0.001), depressive (p < 0.001), and eating symptomatology (p = 0.001), and the interaction between group and SOP was statistically significant when compared with the controls. Mean SPP total score among controls was similar to that in the AN group and higher than that in the OCD group (p = 0.003). Only in the control group did SPP account for significant variance in scores on the measures of obsessive-compulsive (p = 0.002), depression (p = 0.011), and eating symptomatology (p = 0.006). CONCLUSIONS: Self-oriented perfectionism seemed more specific to AN than to OCD or controls. It predicted obsessive-compulsive, depressive, and eating symptoms in the AN group. In healthy controls, SPP was related to obsessive-compulsive, depressive, and eating symptomatology.
OBJECTIF: Le but de l'étude était de comparer les deux dimensions du perfectionnisme, notamment le perfectionnisme auto-orienté (PAO) et le perfectionnisme imposé socialement (PIS), chez des adolescents souffrant d'anorexie mentale (AM) ou du trouble obsessionnel-compulsif (TOC) et chez des sujets témoins. Un autre objectif était d'investiguer l'influence des dimensions du perfectionnisme sur le trouble obsessionnel-compulsif, le trouble dépressif et la symptomatologie alimentaire. MÉTHODES: Ont été recrutés 79 adolescents souffrant d'AM, 32 souffrant du TOC et 74 sujets témoins. L'échelle du perfectionnisme pour enfants et adolescents (CAPS) a servi à évaluer le PAO et le PIS. Des mesures de la dépression, du trouble obsessionnel-compulsif et de la symptomatologie alimentaire ont été administrées. RÉSULTATS: Le groupe d'AM a eu des scores plus élevés au PAO que le groupe du TOC (p < 0,001) et le groupe des témoins (p < 0,001). Dans le groupe d'AM, le PAO représentait une variance significative des scores aux troubles obsessionnels (p < 0,001), dépressifs (p < 0,001), et à la symptomatologie alimentaire (p = 0,001), et l'interaction entre le groupe et le PAO était statistiquement significative lorsque comparée avec les témoins. Le score total moyen du PIS chez les témoins était semblable à celui du groupe d'AM et plus élevé que celui du groupe du TOC (p = 0,003). C'est seulement dans le groupe témoins que le PIS représentait une variance significative des scores aux mesures du trouble obsessionnel-compulsif (p = 0,002), de la dépression (p = 0,011), et de la symptomatologie alimentaire (p = 0,006). CONCLUSIONS: Le perfectionnisme auto-orienté semblait plus spécifique à l'AM qu'au TOC ou aux témoins. Il prédisait les symptômes obsessionnels-compulsifs, dépressifs et alimentaires dans le groupe d'AM. Chez les témoins en santé, le PIS était lié aux symptômes obsessionnels-compulsifs, dépressifs et alimentaires.
RESUMO
Studies of set-shifting in adolescent AN present conflicting results, since not all have found differences with regard to controls. To date, no functional Magnetic Resonance Imaging (fMRI) studies have been carried out in adolescent patients, nor have patients been assessed after weight recovery. In this study, 30 female AN patients aged 12-17 and 16 matched control subjects were assessed both at baseline and after six months and renutrition using a structured diagnostic interview, clinical and neurocognitive scales, and fMRI during a set-shifting task. Adolescent AN patients presented similar performance on different neurocognitive tests and also on a set-shifting task during fMRI, but they showed a lower activation in the inferior and middle occipital and lingual gyri, fusiform gyri and cerebellum during the set-shifting task. No correlations were found between decreased activation and clinical variables such as body mass index, eating or depressive symptoms. After six months of treatment and renutrition in AN patients, there were no differences between patients and controls. These results show that adolescent AN patients have lower activation in relevant brain areas during a set-shifting task, and support the use of fMRI with set-shifting paradigms as a biomarker in future studies.

OBJECTIVE: To assess the experience with, knowledge of, and attitudes toward electroconvulsive therapy (ECT) among parents of adolescents with schizophrenia spectrum disorders (SSD) who have received ECT. METHODS: A self-administered questionnaire was used to assess the experience with, knowledge of, and attitudes toward ECT in a sample of parents of adolescents diagnosed with SSD. Parents of adolescents treated with ECT before the age of 18 years (ECT group; n = 19) were compared with a randomly selected group of parents of adolescents treated only with antipsychotics (No ECT group; n = 20). RESULTS: Most parents in the ECT group claimed that they had received adequate information about the ECT procedure (94.7%), most of them thought it had been helpful for their children (73.7%) and none thought that it had made things worse. The large majority of parents in the ECT group (80%) thought that the illness had been worse than ECT or medication, and none thought that ECT was the worst. Parents in the ECT group generally had better knowledge of what ECT is and its indications. All the parents in the ECT group (100%) and almost all of those in the No ECT group (94.7%) would agree to the treatment for their children if recommended in the future by a doctor, there being no differences between the groups in this respect (p = 0.447). Most parents in the ECT group (88.9%) thought it was a legitimate treatment when used appropriately, an opinion that was held by a much smaller proportion of parents in the No ECT group (52.6%), although the remaining parents in that group were unsure about it (47.4%). CONCLUSIONS: Most parents of adolescents with SSD treated with ECT had positive views about the treatment. Parents of adolescents treated only with antipsychotics tended either to have positive views about ECT or claimed to have no knowledge about it, with negative views being uncommon.

OBJECTIVE: The purpose of this study was to assess, in patients with schizophrenia spectrum disorders (SSD) who received electroconvulsive therapy (ECT) prior to the age of 18, their experience, knowledge, and attitudes toward ECT, and to compare the findings with those obtained in adolescents treated only with antipsychotics. METHODS: Patients diagnosed with SSD (n = 19) and treated with ECT before the age of 18 years (ECT group; n = 19) were compared with a randomly selected group of patients with SSD treated only with antipsychotics (non-ECT group, n = 21). A self-administered questionnaire was used to assess their experience, knowledge, and attitudes. RESULTS: Most adolescents in the ECT group thought that the intervention had been helpful (78.9%) and believed that their illness had been worse than ECT or medication (68.4%). Similarly, almost three quarters of these patients did not believe the treatment to be cruel (73.7%) or outdated (73.7%), or that it should be illegal (68.4%). Patients in the non-ECT group often chose "don't know" as their response to the survey questions, and significant differences between the groups were observed. Most patients in both the ECT group (84.2%) and the non-ECT group (80%) said that they would accept the treatment in the future if necessary, there being no differences between the groups in this respect (p = 0.2). CONCLUSIONS: Most adolescents in the ECT group had positive views about ECT. By contrast, most adolescents in the non-ECT group either did not know or did not have a clear opinion regarding ECT treatment, although they did not have negative views about it.

We describe a case report of an 80-year-old woman who presented with symptomatology compatible with an episode of major depression with catatonia. After psychiatric admission, electroconvulsive therapy (ECT) was applied, but symptoms progressed with cognitive impairment, bradykinesia, widespread stiffness, postural tremor, and gait disturbance. After compatible magnetic resonance imaging (MRI), diffusion changes, and electroencephalogram (EEG) findings the case was reoriented to Creutzfeldt-Jakob disease (CJD). The genetic study found a methionine/valine heterozygosity at codon 129 of the prion protein gene PrP(Sc). On followup, a significant clinical recovery turned out. For this reason, EEG and MRI were repeated and confirmed the findings. The patient subsequently demonstrated progressive clinical deterioration and died 21 months later. The diagnosis was verified postmortem by neuropathology. The vCJD subtype MV2 is indeed characterized by early and prominent psychiatric symptoms and a prolonged disease duration however no frank clinical recovery has before been reported.
