[Waived EEG diagnosis before administration and during drug therapy with methylphenidate: dangerous or justifiable?].

OBJECTIVES: The issue of whether or not to perform an EEG before or during therapy with psychostimulants currently is a topic of controversial discussion. Only a few studies have described the types of EEG alterations that occur in patients without epilepsy who are being treated with psychostimulants. The aim of our study was to assess the types of change in the EEG that occur before and during this treatment so as to be able to formulate recommendations for EEGs in children with ADHD. METHODS: The EEGs of 124 children and adolescents with ADHD before and during treatment with methylphenidate were analyzed retrospectively. RESULTS: In summary the rate of hypersynchronous activity (HSA) during therapy with methylphenidate does not increase. Patients on antiepileptic medication did not show any increased rates of seizures or HSA. CONCLUSIONS: Whether or not methylphenidate medication influences the occurrence of epileptic seizures remains unsettled. Given the data from this study, we would conclude that an EEG during therapy with methylphenidate is not necessary. Before commencing a planned methylphenidate therapy, however, an EEG should be performed.

Clinical behavioral problems in day- and night-wetting children.

In this prospective, clinical study of 167 consecutive wetting children, the associations between specific forms of day and night wetting and clinical behavioral symptoms according to a parental questionnaire (Child Behavior Checklist; CBCL), as well as ICD-10 child psychiatric diagnoses are analyzed. For the entire group, the proportion of children with at least one ICD-10 diagnosis was 40.1% and for the CBCL total problems scale 28.2% - three times higher than in the general population. Expansive disorders (21%) were twice as common as emotional disorders (12%). A significantly higher (P<0. 05) proportion of day-wetting children had at least one diagnosis (52.6%) and emotional disorders (19.5%) compared with nocturnal enuretics (33.6% and 8.2%, respectively). Secondary nocturnal enuretics had significantly higher CBCL total problem scores (39.3% vs. 20.0%, P<0.05) as well as psychiatric ICD-10 diagnoses (75% vs. 19.5%, P<0.001) than primary enuretics. Children with primary monosymptomatic enuresis had the lowest rate of CBCL total behavioral symptoms (14.5%) and diagnoses (10%). Of the day-wetting children, those with voiding postponement had more expansive disorders (39.3% vs. 13.6%, P<0.05) and externalizing symptoms (37% vs. 19.%, NS) than those with urge incontinence. In summary, a third of wetting children showed clinically relevant behavioral problems with specific psychiatric comorbidity for the subtypes. A more-detailed differentiation into syndromes rather than into day/night and primary/secondary forms is needed.

[Incidence of psychiatric symptoms and somatic complaints in 4- to 10-year-old children in Germany as judged by parents--a comparison of norm-oriented and criteria-oriented models].

OBJECTIVES: To analyze the frequency of behavioral/emotional problems and somatic complaints of children aged four to ten as rated by their parents. METHOD: The analysis is based on the PAK-KID study on behavioural and emotional problems and psychosocial competencies of children and adolescents in Germany. In a nationally representative sample of N = 1030 children aged four to ten years the parents rated their child using the Child Behavior Checklist. RESULTS: The prevalence rates of the symptoms are presented. Additionally global prevalence rates based on three different models were calculated and compared. They range from 13.1% to 28.3%. The issues of defining cutoffs necessary for the calculation of prevalence rates are discussed.

[Forms of juvenile aggression].

Delinquent behaviour has its roots in early childhood: Hyperactivity and impulsivity are its precursors, especially if rules are not clearly set in kindergarten and school and if aggressive behaviour is tolerated. Conduct disorders are classified into several subgroups with different treatment strategies. Epidemiologically there is no evidence of an increase of aggression and delinquency in childhood and adolescence. As only a small portion of children and adolescents with aggression and conduct problems are considered to be in need of treatment by their parents, early and intensive intervention is necessary.

[The value of different sources of information in evaluating psychiatric disorders in adolescence--a comparison of parental judgment and self-assessment by adolescents].

Data from the national representative epidemiologic survey (PAK-KID-study) assessed by the German versions of Achenbach'S Child Behavior Checklist and Youth Self-Report of N = 1757 parents and their children aged 11 to 18 years are compared by using the corresponding Cross-Informant-Scales. On all problem scales adolescents report more problems than parents. For some scales the differences between girls and their parents are higher than between boys and their parents (social withdrawal, somatic complaints, anxious/depressed, attention problems, internalizing and total score). Averaged Pearson correlations of the eight subscales are in a moderate rage (r < 0.50). For all problem scales an agreement of 30% in the area of high problems (> PR95) is found. If one informant scores above PR95 the Relative Risk of the other one scoring in this range too is significantly higher than one for nearly all scales.

[Mental disturbances in children and adolescents in Germany. Results of a representative study:age,gender and rater effects].

METHOD: A study on behavioral and emotional problems and competence in children and adolescents in Germany (PAK-KID study) is described. It is the first nationwide representative survey of this kind of children and adolescents aged 4 to 18 years in Germany. For children aged 4 to 10 years the parents completed the German version of Achenbach's Child Behavior Checklist (CBCL 4-18) developed by the Arbeitsgruppe Deutsche Child Behavior Checklist. Children and adolescents aged 11 years and older filled out the German version of the Youth Self-Report that is part of Achenbach's CBCL in addition to the parents completing the German version of the CBCL. A total of 2856 parent questionnaires and 1798 self-report questionnaires completed by children and adolescents were analyzed. RESULTS: The sample was representative with respect to the main sociodemographic variables. On all problem scales children and adolescents aged 11 to 18 years reported significantly more problems than their parents did. The frequency of internalizing problems (social withdrawal, somatic complaints, anxiety/depression) and delinquent behavior of children and adolescents reported by parents increased with the children's age, whereas aggressive behavior and attention problems decreased with age. Girls reported significantly more problems than boys on all internalizing scales of the Youth Self-Report. The effect was not totally replicated in the parent reports. In the parent reports, boys had more attention problems and more aggressive and delinquent behavior than girls.
