RESUMO

BACKGROUND: Ketamine and esketamine have both shown significant antidepressant effects in treatment-resistant depression (TRD), and conflicting evidence suggests that induced dissociation by these drugs can be a clinical predictor of esketamine/ketamine's efficacy. METHODS: This study is a secondary analysis from a bi-center, randomized, controlled trial. Participants were randomly assigned 1:1 to receive an IV infusion of esketamine (.25 mg/kg) or racemic ketamine (.50 mg/kg) over 40 minutes. Dissociative symptoms were assessed using the Clinician-Administered Dissociative State Scale (CADSS) 40 minutes following the beginning of the infusion. The variation in depression scores was measured with the Montgomery-Asberg Depression Rating Scale (MADRS), which was administered before the intervention as a baseline measure and 24 hrs, 72 hrs, and 7 days following infusion. RESULTS: Sixty-one patients were included in the analysis. Examining CADSS scores of 15 or below, for every 1-point increment in the CADSS score, there was a mean change of -0.5 (SD = 0.25; p-value 0.04) of predicted MADRS score from baseline to 24 hrs. The results for 72 hrs and 7 days following infusion were not significant. Limitations: This study was not designed to assess the relationship between ketamine or esketamine-induced dissociation and antidepressant effects as the main outcome, therefore confounding variables for this relationship were not controlled. CONCLUSION: We suggest a positive relationship between dissociation intensity, measured by CADSS, and antidepressant effect 24 hours after ketamine and esketamine infusion for a CADSS score of up to 15 points.

RESUMO

Parents and siblings of children on the autism spectrum experience significant distress, and for this reason, it is essential to understand the most prevalent psychopathological symptoms among this population. This work aims to establish the prevalence of psychopathological symptoms in parents and siblings of individuals on the autism spectrum, following the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) criteria. Searches were carried out using the PubMed/Medline, Embase, PsycINFO, SciELO, and Biblioteca Virtual em Saúde (BVS) databases. Twenty-three articles were included in this review. Depressive symptoms were the most frequently reported conditions, with a higher prevalence in mothers of children on the autism spectrum. In the meta-analysis, mothers of children on the autism spectrum scored higher by 0.42 standard deviations on the symptom scales (SMD 0.42; CI 0.25-0.59), with low statistical heterogeneity (I2 0%, p = 0.5) when compared with mothers of children with atypical development. The psychopathological symptoms of relatives should be investigated as part of the follow-up procedures for the child on the autism spectrum to facilitate their treatment.

RESUMO

BACKGROUND: Racemic ketamine is a mixture of (R)-ketamine (arketamine) and (S)-ketamine (esketamine), with the latter regarded as the main isomer for antidepressant effects. However, preclinical data and one open-label human trial suggest arketamine might exert a more potent and longer-lasting antidepressant effect with fewer side effects. We aimed to explore the feasibility of a randomized controlled trial of arketamine for treatment-resistant depression (TRD) and to assess its efficacy and safety compared to placebo. METHODS: This is a, randomized, double-blind, crossover, pilot trial (n = 10). All participants received saline and arketamine (0.5 mg/kg) with a one-week interval. Treatment effects were analyzed with a linear mixed effects (LME) model. RESULTS: Our analysis suggested the presence of a carryover effect, so the main efficacy analysis was limited to the first week, which demonstrated a main effect of time (p = 0.038) but not for treatment (p = 0.40) or their interaction (p = 0.95). This indicates that depression improved over time, but without significant difference between arketamine and placebo. Analyzing the two weeks together, findings were the same. Dissociation and other adverse events were minimal. LIMITATIONS: This was a pilot study with a small sample and underpowered. CONCLUSIONS: Arketamine was not superior to placebo for TRD but demonstrated to be extremely safe. Our findings reinforce the importance of continuing studies with this drug, with better powered clinical trials, perhaps considering a parallel design with higher or flexible doses and repeated administrations.

RESUMO

OBJECTIVES: Evidence suggests that ketamine's influence on brain-derived neurotrophic factor (BDNF) might be involved in its mechanism of rapid antidepressant action. We aimed to evaluate the differential impact of ketamine and esketamine on serum BDNF levels and its association with response patterns in treatment-resistant depression (TRD). METHODS: Participants (n = 53) are from a randomized, double-blind clinical trial comparing the efficacy of single-dose ketamine (0.5mg/kg, n = 27) and esketamine (0.25mg/kg, n = 26) in TRD. Depression severity was assessed before and 24 hours, 72 hours, and 7 days after the intervention, using the Montgomery-Åsberg Depression Rating Scale (MADRS). Blood samples were collected before infusion, 24 hours, and 7 days afterwards. RESULTS: There were no significant changes in BDNF levels at post-infusion evaluation points, and no difference in BDNF levels comparing ketamine and esketamine. Both drugs exhibited similar therapeutic effect. There was no association between BDNF levels and response to treatment or severity of depressive symptoms. CONCLUSION: There was no significant treatment impact on BDNF serum levels - neither with ketamine nor esketamine - despite therapeutic response. These results suggest that ketamine or esketamine intervention for TRD has no impact on BDNF levels measured at 24 hours and 7 days after the infusion.

RESUMO

INTRODUCTION: In spite of the recent increase in scientific publications showing an expressive interest in studies about social support, there are still scarce publications regarding this thematic and bipolar disorder, mostly when evaluating the individuals in the state of euthymia. Euthymia referred a state that a bipolar patient does not have signs/symptoms of (hipo)mania or depression, thus assessing individuals in this state may reduce response bias. OBJECTIVE: The objective of this study is to identify the impact of social support on bipolar disorder in patients in the euthymic phase. METHODS: A systematic search of observational studies on PubMed/Medline, PsycINFO, EMBASE, Scopus and Web of Science databases was performed from February 2021 to August 2022. RESULTS: In total, seven studies fulfilled the eligibility criteria. According to three studies, bipolar disorder patients had lower social support than healthy controls. Contrastingly, one study showed bipolar patients did not have different social support compared to healthy controls. CONCLUSIONS: Even though few papers with low or middle risk of bias were included in this review, we found that not only does social support could act as a protective factor for bipolar patients but also that clinical manifestations of the disorder seem to affect social support. This systematic review suggests the narrowed evidence field with different measures and type of evaluation from studies on social support and bipolar disorder, which highlights the need for further investigations on this theme.

RESUMO

Introduction: Although pharmacological treatment for Attention-Deficit/Hyperactivity Disorder (ADHD) has demonstrated efficacy, several individuals persist in experiencing social and academic impairment. Additionally, the occurrence of significant side effects may render the use of psychotropic medications untenable. However, Transcranial Direct Current Stimulation (tDCS), a non-invasive brain stimulation technique, shows promising results in treating ADHD. Objectives: To investigate the efficacy and safety of tDCS on the performance of children and adolescents with ADHD in neuropsychological tests involving visual attention, visual and verbal working memory, and inhibitory control. Methodology: This study was a triple-blind, randomized, sham-controlled, crossover clinical trial. The intervention consisted of a daily session of tDCS (2 mA) or sham targeting the left dorsolateral prefrontal cortex (L-DLPFC), for 30 min, on five consecutive days. The primary outcome was change in the Visual Attention Test, Fourth Edition (TAVIS-4) before and after each intervention. Subjects were also evaluated pre and post-tDCS using the Digit Span subtest of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), the Developmental Neuropsychological Assessment, Second Edition (NEPSY-II) Inhibiting Response (IR) subtest, and the Corsi Block-Tapping Task. Results: Fifteen individuals were included, and no statistically significant difference was observed when comparing the results of the TAVIS-4, the IR of NEPSY-II, and the intragroup Digit Span subtest of WISC-V undertaken before and after the procedure. Adverse events were mainly self-limiting and transient. The participants did not perceive any benefit from tDCS when measured on the Patient Global Impression of Improvement (PGI-I) Scale. Conclusion: This study did not meet its primary endpoint and found no performance enhancement in any investigated neuropsychological outcomes relating to the intervention group.

RESUMO

Schuurs-Hoeijmakers syndrome, an autosomal dominant disorder associated with mutations in the PACS1 gene, was initially identified in two unrelated children of European descent from a cohort of individuals with intellectual disabilities. This gene alteration significantly reduced cranial cartilaginous structures, inducing craniofacial alterations predominantly in a dominant-negative fashion. In this paper, we report a novel variant of PACS1 associated with Schuurs-Hoeijmakers syndrome: a boy aged two years and nine months of indigenous descent presenting with motor stereotypies, atypical sensory searches, language delay, and low socio-interactional reciprocity. Whole exome sequencing confirmed the presence of a heterozygous missense mutation c.943C>T p. (Arg315Trp) in the PACS1 gene. The phenotypic profile identified was similar to the other cases of Schuurs-Hoeijmakers syndrome described in the literature. This report highlights the importance of considering the possibility of PACS1 gene alterations and a diagnosis of Schuurs-Hoeijmakers syndrome in patients presenting craniofacial alterations associated with autistic features, psychomotor and language development delay.

RESUMO

BACKGROUND: Major depressive disorder (MDD) is a leading cause of disability worldwide and most people do not achieve symptom remission. Treatment-resistant depression (TRD) is characterized by the failure of at least one adequate trial of a major class of antidepressant, with adequate time and dosage. We aimed to identify clinical predictors of depressive symptom remission and response 24 h and 7 days after racemic ketamine and esketamine infusions. METHODS: A randomized, double-blind, active-controlled, non-inferiority trial using ketamine and esketamine in TRD. Individuals diagnosed with MDD according to Diagnostic and Statistical Manual of Mental Disorders version IV and fulfilling TRD criteria were recruited from March 2017 to June 2018. Participants received a single subanesthetic dose of ketamine (0.5 mg/kg) or esketamine (0.25 mg/kg) for 40 min. Depressive symptoms were assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS) and symptom remission was defined as a MADRS score ≤7 and response defined as ≥50% reduction in depressive symptom severity, 24 h and 7 days after the infusion. Clinical variables were selected based on previous clinical trials. Stepwise backward logistic regression was used, considering a confidence level of 95%. RESULTS: 61 subjects were included: 39 (63.9%) were females with a mean age of 47.2 ± 14.9. Higher number of therapeutic failures (Odds Ratio (OR) = 0.677; 95% confidence interval (CI): 0.47-0.97) and higher severity of illness (OR = 0.912; 95% CI: 0.83-0.99) were associated with fewer remissions of depressive symptoms 7 days after intervention, and with fewer response in 24 h (OR = 0.583; 95% CI: 0,40; 0,84 and OR = 0.909; 95% CI: 0,83; 0,99, respectively). CONCLUSION: Number of treatment failures and severity of illness were predictors of fewer remissions and responses of depressive symptoms in this TRD population. Study of predictors of remission may contribute to better selection patients that may benefit from receiving ketamine.

RESUMO

PURPOSE: Investigate the effect of botulinum toxin type-A (BoNT-A) on spasticity and motor performance in children with Cerebral Palsy (CP) related to Congenital Zika Syndrome (CZS). METHODS: Prospective longitudinal observational study of 34 children with CP referred for BoNT-A treatment. Outcomes were evaluated with a muscle tone assessment scale (Modified Ashworth Scale - MAS) and the Patients' Global Impression of Improvement (PGI-I) scale. RESULTS: Mean age was 32.06 ± 3.07 months and 85% were classified as Gross Motor Function Classification System (GMFCS) V. Primitive reflexes were present in 56% of the sample. The majority of the parents (97.9%) reported improvement in range of motion or reduction in spasticity after treatment with botulinum toxin. No side effects were recorded. When compared to the baseline, median reduction in the MAS was 0.5 (IQR = 0). CONCLUSIONS: The findings of this study suggest that BoNT-A may effectively promote functional improvements and reduce muscle tone, improving the child's and family's quality of life.

RESUMO

OBJECTIVE: Human T-cell lymphotropic virus type-1 (HTLV-1) infection is a neglected tropical disease associated with many clinical manifestations, such as erythematous-scaling skin lesions, cutaneous lymphomas, and spastic paraparesis, which could be a potential cause of mental health concerns. This study investigates the prevalence of symptoms and diagnoses of depression and anxiety and its associated factors in people living with HTLV-1 (PLWH). METHOD: A systematic review was performed in the Pubmed/MEDLINE, Embase, LILACS, and PsycINFO databases for original studies investigating symptoms of depression and anxiety and diagnoses of major depressive disorder and anxiety disorders in PLWH, and a random-effects meta-analysis with meta-regression was performed to obtain a summary frequency of symptoms and diagnoses of depression and anxiety. RESULTS: Considering both symptoms and diagnoses, the pooled prevalence for depression was 35% (95% CI: 27 to 43) and for anxiety was 33% (95% CI: 23 to 45). Clinically significant symptoms were more prevalent than diagnosed disorders for depression (47% vs. 21%) and anxiety (44% vs. 11%). PLWH were more likely than seronegative controls to present symptoms and diagnoses of depression (pooled OR: 4.25; 95% CI: 2.7 to 6.68) and anxiety (pooled OR: 3.79; 95% CI: 2.6 to 5.52). Spastic paraparesis was significantly associated with symptoms and diagnoses of depression (pooled OR: 1.81; 95% CI: 1.11 to 2.95) and anxiety (pooled OR: 2.75; 95% CI 1.26 to 5.96). CONCLUSIONS: PLWH present a much higher prevalence of symptoms and diagnoses of depression and anxiety than seronegative controls, which could be explained by social vulnerability or neurological impairment associated with spastic paraparesis. More studies comparing asymptomatic PLWH and seronegative controls are needed.

RESUMO

Dissociative symptoms are common, possibly severe, side effects associated with the use of ketamine and esketamine in depression. We investigated the relationship between trait dissociation and dissociation induced by ketamine and esketamine used as augmentation therapy in treatment-resistant depression (TRD). Adults with TRD were randomly assigned to receive a single intravenous infusion, with a duration of 40 min, of either esketamine 0.25 mg/kg or ketamine 0.5 mg/kg. We assessed trait dissociation with the Dissociative Experience Scale (DES) and, to evaluate induced dissociation, the Clinician-Administered Dissociative States Scale (CADSS) was used. Thirty-two subjects received esketamine and 29 received ketamine. The groups had similar median DES scores (p = 0.26). More than 30% of the patients in both groups had DES scores ≥30 points. The median CADSS score in the esketamine group was equivalent to that in the ketamine group (p = 0.40). Every 5 points increment in the DES was associated with a 10.9% (95% CI 4.5-17.8%) increase in the CADSS, in an exponential fashion when the two groups were pooled together. Subjects with high trait dissociation had a higher risk of induced dissociation state (relative risk [RR] 1.41, 95% CI 1.11-1.78) and very high induced dissociation (RR 3.05, 95% CI 1.14-8.15). Induced dissociation was not a serious adverse effect. The findings suggest that trait dissociation is a predictor of induced dissociation by Ketamine or Esketamine in TRD subjects. Screening for trait dissociation and counseling patients with high trait dissociation on the risks of dissociation by these drugs are recommended.

RESUMO

OBJECTIVE: The main aim of this study was to determine the impact of botulinum toxin A (BTX-A) on severity and frequency of drooling in children with Cerebral Palsy (CP) secondary to Congenital Zika Syndrome (CZS). METHODS: This is a prospective longitudinal observational study including 23 children who received bilateral injections of BTX in the parotid and submandibular glands. The Thomas-Stonell & Greenberg Drooling Severity and Frequency Scale was applied by a multidisciplinary team including Speech, Language and Hearing professionals. The Global Impression of Improvement (GII) Scale was also applied to assess parents' subjective perceptions of therapeutic response. Swallowing was assessed using Doppler ultrasonography. Univariate logistic regression was used to analyse differences between responders and non-responders. RESULTS: Participant age varied from 27 to 38 months (mean 31.78, SD = 2.61) all presented with Gross Motor Function Classification System (GMFCS) V. Drooling Severity and Frequency Scale scores ranged from 7 to 9 points (median = 9) prior to BTX administration and from 4 to 6 (median = 6) after. Pre- and post-treatment reduction in drooling severity occurred (Z = -3.746; p < 0.001). No cases of drooling worsening were reported. Only two subjects presented adverse effects attributed to BTX administration. Correlation was only confirmed with GII. DISCUSSION: This article presents the safe and positive impact of BTX-A administration guided by anatomical references described in the literature, even on children with microcephaly. Further studies are needed to facilitate the use of Doppler ultrasonography as a tool to characterize changes in sensory processing and motor response following intraoral input in children with CP.

RESUMO

We aimed to analyze the efficacy and safety of arketamine, the R(-)-enantiomer of ketamine, for treatment-resistant depression (TRD) in humans. Open-label pilot trial, seven subjects with TRD received a single intravenous infusion of arketamine (0.5 mg/kg); primary outcome was change in Montgomery-Åsberg Depression Rating Scale (MADRS) 24 h after. Mean MADRS dropped from 30.7 before infusion to 10.4 after one day, a mean difference of 20.3 points [CI 95% 13.6-27.0; p < 0.001]; dissociation was nearly absent. Arketamine might produce fast-onset and sustained antidepressant effects in humans with favorable safety profile, like previously reported with animals; further controlled-trials are needed.

RESUMO

The lack of predictive biomarkers for therapeutic responses to schizophrenia leads clinical procedures to be decided without taking into account the subjects' neuroanatomical features, a consideration, which could help in identifying specific pharmacological treatments for the remission of symptoms. Magnetic resonance imaging (MRI) is a technique widely used for radiological diagnosis and produces 3-dimensional images in excellent anatomical detail, and with a great capacity to differentiate soft tissue. Various MRI techniques of the human brain have emerged as a result of research, enabling structural tests that may help to in consolidate previous findings and lead to the discovery of new patterns of abnormality in schizophrenia. A literature review was undertaken to assess the superior temporal gyrus (STG) as a possible biomarker in schizophrenia with the use of voxel-based morphometry of the brain using MRI. Many findings in studies of schizophrenia using MRI have been inconclusive and, in some cases, conflicting, although interesting results have been obtained when attempting to correlate neuroimaging changes with aspects of clinical features and prognosis of the disease. The individuals affected by this mental illness appear to have smaller STG volumes when compared to healthy controls and also to subjects with a diagnosis of first-episode affective psychosis or groups of individuals at high risk of psychosis. However, the wide variety of definitions surrounding the STG found in a number of studies is a contributing factor to the lack of correlation between brain abnormalities and clinical symptoms. For instance, disagreements have arisen due to studies using regions of interest to analyze the STG whereas other studies prioritize the analysis of only STG subregions or specific supratemporal plane regions. It is necessary to standardize the nomenclature of the areas to be studied in the future, as this will enable more consistent results, allowing higher clinical and morphological correlations.

RESUMO

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) leads to a drastic reduction in quality of life, generating intense psychological distress and predisposing those affected to mental illness and, in more severe cases, suicidal behavior. OBJECTIVE: This is a systematic review aiming to estimate the frequency of wish to die, suicide ideation and suicide in individuals with ALS using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). METHODS: The following databases were used: Pubmed/MEDLINE, PsycINFO, Embase, SciELO, Biblioteca Virtual de Saúde (BVS), and Cochrane Library. The choice of appropriate descriptors, or their equivalents, to define the search terms was based on the technical and scientific vocabulary of each database. RESULTS: 13 articles were included in the present systematic review, of which three were cross-sectional studies, nine were cohort-type and there was one case-control study. The studies show that individuals with ALS have a higher risk of suicide in relation to the general population, and there is evidence that this risk is even higher in the early stages of the disease. Major Depressive Disorder was the most prevalent mental disorder in the studies included. This mental health concern is often undertreated, leading to the increased susceptibility of this population to suicide. LIMITATIONS: In general, the study samples represent a highly heterogeneous population while many instruments used in the data collection were not uniform. CONCLUSIONS: The high degree of psychological vulnerability of this population, associated with a greater predisposition to suicidal behavior, should be minimized through public health measures.

RESUMO

Alteration of the KPTN gene, responsible for the coding of kaptin (a protein involved in actin cytoskeletal dynamics), causes a syndrome characterized by macrocephaly, neurodevelopmental delay and epileptic seizures. We report the first Brazilian case of KPTN gene variation, previously described in nine subjects from four interlinked families from an Amish community in Ohio, two Estonian siblings and a 9-year-old boy from Kansas City. We report a case of KPTN-related syndrome in a 5-year-old child which presented macrocephaly, muscular hypotonia, and global development delay. The neurological examination revealed below-expected performance in coordination and balance tests, dyspraxia, and hand-mouth synkinesia. Expressive language was characterized by phono-articulatory imprecision, abundance of phonological processes and morphosyntactic immaturity. Neuropsychological assessment revealed intellectual disability with impairment of verbal and executive functions. Exome sequencing was performed. Analysis revealed a homozygous 2-nucleotide duplication c.597_598dup p.(Ser200Ilefs*55) in the KPTN gene, which is predicted to lead to a translational frameshift and formation of a premature stop codon. The phenotypic profile is similar to the cases described in the other families. Presence of macrocephaly and delayed development indicate the possibility of KPTN gene variation. Genetic testing should be carried out at an early stage in order to reach a timely diagnosis.

RESUMO

AIM: To estimate the prevalence of mental illness in parents of children with cerebral palsy (CP). METHOD: This is a systematic review that follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols in the search for observational studies determining the prevalence of depression, anxiety, and substance abuse in parents of individuals with CP. The information sources used for this study were: PubMed, SciELO, Cochrane Library, Clinical Trials, and Biblioteca Virtual de Saúde. RESULTS: Fourteen articles were selected and included, investigating 1264 mothers and 105 fathers of children with CP. Data extracted for analysis were divided into three categories: study data, data about participants with CP, and data about parents. All studies included volunteer parents, of whom 95 per cent were female. INTERPRETATION: CP is related to a higher prevalence of symptoms of depression and anxiety in parents. Factors such as a child's degree of functionality and socioeconomic level may influence the frequency of mental disorders in parents. However, these studies have heterogeneous samples and applied different criteria to characterize their populations. WHAT THIS PAPER ADDS: Depression and anxiety are more prevalent for parents of children with cerebral palsy (CP) than parents of typically developing children. The child's illness severity is a risk factor for mental illness in parents of children with CP. The more time spent on child care, the higher the risk of mental illness among mothers of children with CP. There is a lack of reliable data in the literature on substance abuse in parents of children with CP.


PREVALENCIA DE DEPRESIÓN, ANSIEDAD Y TRASTORNOS RELACIONADOS AL USO DE SUSTANCIAS EN PADRES DE NIÑOS CON PARÁLISIS CEREBRAL: REVISIÓN SISTEMÁTICA: OBJETIVO: Calcular la prevalencia de enfermedad mental en padres de niños con parálisis cerebral (PC). METODO: Esta es una revisión sistemática que sigue la metodología para Protocolos de Revisiones Sistemáticas y Metaanálisis en la búsqueda de estudios observacionales que determinan la prevalencia de depresión, ansiedad y abuso de sustancias en padres de individuos con PC. Las fuentes de información utilizadas para este estudio fueron: PubMed, SciELO, LILACS, Biblioteca Cochrane, Clinical Trials, y Biblioteca Virtual de Saúde. RESULTADOS: Se seleccionaron e incluyeron 14 artículos, investigando 1.264 madres y 105 padres de niños con PC. Los datos extraídos para análisis fueron divididos en tres categorías: datos de estudio, datos sobre participantes con PC y datos sobre padres. Todos los estudios incluyeron padres voluntarios, de quienes el 95% fueron del sexo femenino. INTERPRETACIÓN: La PC está relacionada a una mayor prevalencia de síntomas de depresión y ansiedad en los padres. Factores como el grado de funcionalidad del niño y el nivel socioeconómico pueden influir en la frecuencia de trastornos cognitivos en los padres. Sin embargo, estos estudios tienen muestras heterogéneas y utilizaron diferentes criterios para caracterizar a las poblaciones.


PREVALÊNCIA DE DEPRESSÃO, ANSIEDADE, E DESORDENS RELACIONADAS AO USO DE SUBSTÂNCIAS EM PAIS DE CRIANÇAS COM PARALISIA CEREBRAL: UMA REVISÃO SISTEMÁTICA: OBJETIVO: Estimar a prevalência de doença mental em pais de crianças com paralisia cerebral (PC). MÉTODO: Esta é uma revisão sistemática que segue o protocol Itens preferenciais para reportar em revisões sistemáticas e metanálises na busca por estudos observacionais que determinassem a prevalência de depressão, ansiedade, e abuso de substâncias nos pais de indivíduos com PC. As fontes de informação usadas para este estudo foram: PubMed, SciELO, LILACS, Cochrane Library, Clinical Trials, e Biblioteca Virtual de Saúde RESULTADOS: Quatorze artigos foram selecionados e incluídos, investigando 1264 mães e 105 pais de crianças com PC. Os dados extraídos para análise foram divididos em três categorias: dados dos estudos, dados sobre os participantes com PC, e dados sobre os pais. Todos os estudos incluíram pais voluntários, dos quais 95 por cento eram mulheres. INTERPRETAÇÃO: A PC se relaciona com maior prevalência de sintomas de depressão e ansiedade em pais. Fatores como grau de funcionalidade da criança e nível socioeconomico podem infuenciar a frequência de desordens cognitivas nos pais. No entanto, estes estudos têm amostras heterogêneas e aplicaram diferentes critérios para caracterizar suas populações.
