ABSTRACT
Psychogenic nonepileptic seizures (PNES) are observable changes in behavior or consciousness that are similar to epileptic seizures but are not associated with electrophysiologic changes. PNES occur in children with underlying psychological distress and are especially frequent in those with epilepsy. Because PNES are heterogeneous, comprehensive treatment tailored to each patient is required to reduce psychosocial stress. Currently, reports regarding children with PNES concomitant with autism spectrum disorder (ASD) do not exist, and effective treatment strategies for these children are lacking. In this case report, we describe a 10-year-old Japanese girl with undiagnosed ASD who developed PNES while undergoing treatment for benign childhood epilepsy with centrotemporal spikes. She exhibited hypersensitivity to sound and interpersonal conflicts caused by social communication deficits. The PNES symptoms improved shortly after our intervention, which was designed to reduce her distress caused by auditory hypersensitivity and impaired social communication, both characteristics of ASD. To the best of our knowledge, this is the first report describing PNES in a child with ASD. Our findings suggest that PNES can result from psychological distress in children with undiagnosed ASD and highlight the importance of examining ASD traits in patients with PNES.
ABSTRACT
Background: Children with autism spectrum disorder (ASD) have varied comorbidities. With regard to comorbidity, there has been increasing interest in bipolar disorder (BP) in children. However, the prevalence of BP with ASD has varied because of the methodological differences used. Therefore the adequate criteria for determining BP in children are still debated. The purpose of this study is to identify reliable prevalence of BP and to evaluate a variety of subclinical BP symptoms in children with ASD. Methods: This is a cross-sectional and case-control study. The participants were 110 referred children aged 6-15 years: 46 with ASD (the case group), 64 without ASD (the control group). We used the strict operational criteria for diagnosing BP, and assessed the presence of subclinical BP symptoms using a semi-structured diagnostic interview. Results: None of the children were diagnosed with BP in the case group, although two children were diagnosed with BP in the control group. Based on the subclinical BP symptoms, the prevalence of elation/expansive mood and racing thoughts was significantly higher in the case group than in the control group: 26.1% versus 3.1% (p<.001) and 32.6% versus 9.4% (p=0.002), respectively. Conclusions: Our finding indicates that school-aged ASD children frequently present subclinical BP symptoms. It is important to be aware of over-diagnosis of BP, even though the children present subclinical BP symptoms, and to provide -the children with effective treatments.

BACKGROUND: Non-psychotic delusions are reported to be associated with depression and anxiety. When these delusions occur in high-functioning pervasive developmental disorder (HFPDD) children, they are often misdiagnosed as schizophrenia and have consequently been studied less. This study has three goals: to investigate the prevalence of non-psychotic delusions in HFPDD children, to test the hypothesis that HFPDD children are more likely to have non-psychotic delusions than non-HFPDD children, and to test the hypothesis that non-psychotic delusions are associated with depression and anxiety. METHODS: This is a cross-sectional and case-control study. The participants were 45 HFPDD children (cases) and 51 children without HFPDD (controls). Semi-structured interviews were conducted to assess the presence of non-psychotic delusions. We used the Child Behavior Checklist (CBCL) to assess levels of anxiety and depression. RESULTS: Of the cases, 62.2% had non-psychotic delusions, which was significantly higher than controls (25.5%, p<0.001, OR: 4.81, 95% CI: 2.01-11.51). Cases tended to score higher for internalizing problems (including anxiety and depression) on the CBCL than controls (69.8±9.4 vs 65.9±10.4, t= 1.9, p=0.062). Cases with non-psychotic delusions scored significantly higher for internalizing problems in CBCL than children without non-psychotic delusions (72.2±7.7 vs 65.7±10.7, t=2.4, p= 0.022). CONCLUSIONS: More than half of the HFPDD children were suffering from non-psychotic delusions, and these delusions were associated with anxiety and depression. Therefore, accurate diagnoses of non-psychotic delusions should be conducted for appropriate treatments to be prescribed.

BACKGROUND: Studies have shown that children with pervasive developmental disorder (PDD) have high rates of sensory hypersensitivity. In addition, a few recent studies suggested that sensory hypersensitivity was related to anxiety or depression. However, most studies had methodological limitations because they included children with mental retardation and did not examine broadband psychopathology. Therefore, the purpose of this study was to examine the prevalence of sensory hypersensitivity in children with high-functioning PDD (HFPDD) and the correlation among sensory hypersensitivity, various characteristics, and broadband psychopathology. METHODS: We assessed 132 children with HFPDD (aged 6-15 years, 75% male) that were divided into sensory hypersensitivity (HS) and sensory non-hypersensitivity (non-HS) groups. A logistic regression model was used to examine correlations among sensory hypersensitivity, age, gender, PDD subtypes, socioeconomic status, and broadband psychopathology, including symptoms of anxiety and depression. RESULTS: Of the 132 children with HFPDD, 65.9% (n = 87) were categorized as HS and 34.1% (n = 45) as non-HS. The most common sensory hypersensitivity was auditory. Logistic regression analyses revealed that sensory hypersensitivity in HFPDD was significantly associated with autistic disorder and symptoms of anxiety and depression. CONCLUSIONS: Majority of children with HFPDD exhibited sensory hypersensitivity. Our findings suggested that sensory hypersensitivity may be a core feature of HFPDD and is possibly correlated to symptoms of anxiety and depression. We propose that sensory hypersensitivity in children with PDD should be aggressively assessed.
