Abstract
Preschool identification of and intervention for psychiatric symptoms has the potential for lifelong benefits. However, preschool identification of thought disorder, a symptom associated with long term risk for social and cognitive dysfunction, has received little attention with previous work limited to examining preschoolers with severe emotional and behavioral dysregulation. Using story-stem methodology, 12 children with ADHD and 12 children without ADHD, ages 4.0-6.0 years were evaluated for thought disorder. Thought disorder was reliably assessed (Cronbach's alpha = .958). Children with ADHD were significantly more likely than children without ADHD to exhibit thought disorder (75 vs 25 %; Fischer's Exact Test = .0391). Thought disorder can be reliably assessed in preschool children and is present in preschool children with psychiatric illness including preschool children with ADHD. Thought disorder may be identifiable in preschool years across a broad range of psychiatric illnesses and thus may be an appropriate target of intervention.

Abstract
BACKGROUND Authors of the Diagnostic and Statistical Manual, Fifth Edition (DSM-V) have recommended to "integrate dimensions into clinical practice." The epidemiology and associated phenomenology of formal thought disorder (FTD) have been described but not reviewed. We aimed to carry out a systematic review of FTD to this end. METHODS A systematic review of FTD literature, from 1978 to 2013, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS A total of 881 abstracts were reviewed and 120 articles met inclusion criteria; articles describing FTD factor structure (n = 15), prevalence and longitudinal course (n = 41), role in diagnosis (n = 22), associated clinical variables (n = 56), and influence on outcome (n = 35) were included. Prevalence estimates for FTD in psychosis range from 5% to 91%. Dividing FTD into domains, by factor analysis, can accurately identify 91% of psychotic diagnoses. FTD is associated with increased clinical severity. Poorer outcomes are predicted by negative thought disorder, more so than the typical construct of "disorganized speech." CONCLUSION FTD is a common symptom of psychosis and may be considered a marker of illness severity. Detailed dimensional assessment of FTD can clarify diagnosis and may help predict prognosis.

Abstract
OBJECTIVE Children and adolescents with schizophrenia share a similar pattern of phenomenological, genetic and cognitive abnormalities to adults with schizophrenia. However, an early-onset of schizophrenia (EOS) (prior to 18 years of age) is associated with a higher frequency of risk indicators associated with schizophrenia (e.g. developmental delays and familial spectrum disorders) and a worse long-term outcome. This overview examines recent research on the neurobiological alterations, possible causes, developmental trajectory and treatment of EOS and attempts to identify gaps in the field. METHOD The authors provide a selective review of major findings from genetics, neuroimaging and treatment studies of pediatric schizophrenia that were presented at a workshop sponsored by the National Institute of Mental Health. These data are synthesized in conjunction with preclinical studies into a model of the pathophysiology of EOS. RESULTS EOS is associated with a high frequency of cytogenetic abnormalities (e.g. velocardiofacial syndrome, sex chromosome anomalies) and other rare denovo chromosomal aberrations. Brain imaging research in adolescents with EOS has revealed a progressive loss of cortical grey matter post-onset of psychosis and subtle abnormalities in white matter microstructure. Although EOS patients are more likely to be treatment-refractory than their adult counterparts, there are substantial data that this subgroup is particularly responsive to clozapine. CONCLUSIONS Genetic or environmental factors operating during adolescence that reduce frontal capacity might contribute to an EOS in susceptible individuals. Additional longitudinal studies of adolescents with schizophrenia are needed to better understand the relationship between structural changes in fronto-limbic regions, stress responsivity, and cognitive and neurochemical development.

Abstract
AbstractBased on findings that, like schizophrenic children, children with complex partial seizure disorder have illogical thinking, this study examined whether or not these same epileptic subjects had other thought processing impairments found in schizophrenic children. Compared to normal children (N = 38), both the epileptic (N = 27) and schizophrenic children (N = 31) underutilized discourse (cohesive) devices that make speech coherent. The severity of the discourse deficits and formal thought disorder of the schizophrenic children was associated with age, but not with IQ scores. Age, IQ, and seizure-related, not behavioral variables, were associated, however, with the severity of the discourse deficits of the epileptic subjects. The study' findings suggest that measures of impaired thought processing and communication in schizophrenic children could be a model to study the developmental impact of complex partial seizure disorder in middle childhood. The clinical implications of the study's findings are discussed.

Abstract
This study compared thought disorder (i.e., impaired use of language to formulate and organize thoughts) in 93 children with complex partial seizures (CPSs) and 56 children with primary generalized epilepsy with absence (PGE) and its relationship to age, seizure, cognitive, and linguistic variables. By the use of psychopathology, social competence, academic achievement, and school problem measures, the functional implications of thought disorder in these two groups were compared. When demographic variables were controlled for, there were no significant differences in thought disorder scores between the CPS and PGE groups. However, the profile of age, gender, seizure, and cognitive variables related to thought disorder differed in the CPS and PGE groups. Within each group, different aspects of thought disorder were associated with different seizure variables. Thought disorder was related to psychopathology, school problems, decreased academic achievement, and poor peer interaction in the CPS group, but with school problems in the PGE group. These findings suggest that CPS and PGE affect the normal maturation of children's discourse skills, albeit through different mechanisms. The relationship of thought disorder to behavioral, academic, and social problems implies that these discourse deficits are one component of the developmental disabilities or comorbidities associated with pediatric CPS and PGE.

Abstract
PURPOSE This study examined the relation between psychiatric diagnosis and mental health services in children with epilepsy and the associated demographic, cognitive, linguistic, behavioral, and seizure-related variables. METHODS The Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS), the Child Behavior Checklist, the Test of Language Development, and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were administered to 114 children, aged 5 to 16 years, with either complex partial seizures (CPS) or primary generalized with absence (PGE, petit mal). A Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) diagnosis and information regarding mental health services were derived from the K-SADS. RESULTS Although approximately 60% of the subjects had a DSM-IV psychiatric diagnosis, >60% received no mental health treatment. Absence of mental health care was associated with younger age, less parental education, limited number of antiepileptic drugs (AEDs; i.e., one or none), and higher verbal IQ. In addition, children with PGE and a single psychiatric diagnosis were less likely to have a history of mental health treatment. CONCLUSIONS This is the first study to demonstrate unmet mental health need in a large sample of children with CPS and PGE. The study's findings suggest that parents and clinicians should be aware of the mental health needs of children with epilepsy, particularly if they have one or more of the identified risk factors.

Abstract
BACKGROUND This study examined measures of social communication that involve the use of language in formulating and organizing thoughts and its relationship with seizure-related, developmental, cognitive, and behavioral variables in 92 children with complex partial seizure disorder (CPS), 51 with primary generalized epilepsy (PGE), and 117 normal children, aged 5.1-16.9 years. METHODS Coding the children's speech samples with the Kiddie Formal Thought Disorder Rating Scale (Caplan et al., 1989) and Halliday and Hasan's (1976) analysis of cohesion demonstrated social communication deficits in both seizure disorder groups. RESULTS The CPS patients had both formal thought disorder and cohesion deficits and the PGE group had mild cohesion deficits. IQ, as well as fronto-temporal and bilateral spike and wave activity were associated with the severity of the social communication deficits of the CPS group. The social communication deficits of the PGE group, however, were related to IQ and seizure control. CONCLUSIONS Recurrent CPS and PGE and fronto-temporal localization of epileptic activity might impair the development of children's communication skills.

Abstract
This study examined if children with complex partial seizures disorder (CPS) and primary generalized epilepsy with absence (PGE) were impaired in the use of self-initiated repair during a conversation compared to normal children. Transcriptions of speech samples of 92 CPS, 51 PGE, and 65 normal children, ages 5-16 years, were coded for self-initiated repair according to Evans (1985). The WISC-R, a structured psychiatric interview, and seizure-related information were obtained for each child. We found impaired use of repair in both the CPS and PGE groups compared to the normal subjects. The CPS patients, particularly those with a temporal lobe focus, overused self-initiated corrections of referents and syntax compared to the PGE and normal subjects. The CPS and PGE patients with frontal lobe involvement underused fillers compared to the normal children. These findings provide additional evidence that both CPS and PGE impact the ongoing development of children's communication skills.

Abstract
Structured psychiatric interviews were administered to 60 children with complex partial seizure disorder (CPS), 40 children with primary generalized epilepsy with absences (PGE), and 48 control children, aged 5 to 16 years. Significantly more patients with epilepsy had psychiatric diagnoses compared with the control children. There were no statistically significant differences, however, in the number of patients with CPS and PGE with psychiatric diagnoses. Other than a schizophrenia-like psychosis found only in the patients with CPS, the two groups of patients had similar psychiatric diagnoses. The presence of psychopathology was related to significantly lower IQ scores and socioeconomic status, but not to seizure-related factors. These findings suggest that the psychopathology of children with CPS and PGE reflects different subtle neuropsychological deficits.

Abstract
OBJECTIVE To examine whether formal thought disorder and psychopathology occurred in children with complex partial seizures (CPS) rather than children with primary generalized epilepsy with absences (PGE) or nonepileptic children. METHOD Formal thought disorder was coded in 30 children with CPS, 24 children with PGE, and 61 nonepileptic children, and structured interview-based psychiatric diagnoses were obtained for the epileptic subjects. RESULTS The CPS subjects had significantly more illogical thinking than the PGE and nonepileptic children. The severity of their illogical thinking was related to global cognitive dysfunction and a schizophrenia-like psychosis. Age of onset and seizure control, however, were significantly associated with the severity of illogical thinking in the PGE group. One or more psychiatric diagnoses were found in 63% of the CPS and 54% of the PGE patients, particularly if they had global cognitive deficits. CONCLUSION Illogical thinking, associated with cognitive dysfunction or schizophrenia-like symptoms, might be a feature of pediatric CPS. Psychopathology might be related to global cognitive dysfunction in pediatric CPS and PGE.

Abstract
The nature of the thinking disturbances found in adolescent-onset psychotic conditions is not as well-characterized as the thought disorders found in adult psychotic patients. We used the Thought Disorder Index to examine whether schizophrenic patients in whom psychotic symptoms appear in adolescence show the same characteristic features of thought disorder as do adult schizophrenics. Quantitative and qualitative features of thought disorder were assessed in psychiatric inpatients with adolescent-onset schizophrenia, psychotic depression, and nonpsychotic conditions compared with normal control adolescents. Elevated thought disorder occurred in all groups of adolescents hospitalized for an acute episode of psychiatric illness. The magnitude of the elevation and the frequency of occurrence of disordered thinking were greatest in the psychotic adolescents. The qualitative features of the thought disturbances found in the schizophrenic adolescents were distinct from those observed in adolescents with psychotic depression. The thinking of the schizophrenic adolescents resembled that of adult schizophrenics. In both conditions thought disorder is characterized by idiosyncratic word usage, illogical reasoning, perceptual confusion, loss of realistic attunement to the task, and loosely related ideas.

Abstract
OBJECTIVE This paper delineates the evolution of the concept of thought disorder and presents a developmental/neurobehavioral theory of the main components of formal thought disorder in childhood-onset schizophrenia. METHOD A review of past and recent clinical, cognitive, and linguistic studies of thought disorder in childhood-onset schizophrenia presents the main features and changes in the thought disorder concept. RESULTS The review emphasizes that, in the past, this term was used to describe a variety of clinical manifestations in a heterogenous group of children because of the lack of distinction between childhood schizophrenia and infantile autism. The studies that have been conducted during the past 15 years, however, have demonstrated well-defined clinical components of thought disorder and their cognitive/information processing, linguistic/pragmatic, and biological correlates. CONCLUSIONS A functional conceptualization of formal thought disorder in childhood-onset schizophrenia is presented in light of the theoretical and clinical implications of the reviewed studies.

Abstract
OBJECTIVE To examine formal thought disorder and discourse (cohesive) devices that make speech coherent prospectively in seven children, aged 5.7 to 16.7 years, before and after temporal lobectomy for intractable cut points determined from sensitivity and specificity analyses of formal thought disorder and discourse measures in 22 children with complex partial seizure disorder and 45 normal children. RESULTS Before surgery, the mean illogical thinking and discourse scores of the surgical candidates were in the pathological range. After a mean postoperative follow-up period of 15.1 months, their illogical thinking (but not their discourse scores) decreased significantly to the normal range. CONCLUSIONS These preliminary findings are discussed in terms of the possible role of postsurgical changes in seizure control, behavior, antiepileptic drugs, cognition, and prefrontal function.
