ADHD often affects multiple generations in a family. Previous studies suggested that children with ADHD benefit less from therapy if parents are also affected, since ADHD symptoms interfere with treatment implementation. This two-group randomised controlled trial examined whether targeting maternal ADHD boosts the efficacy of parent-child training (PCT) for the child's ADHD. Here, we report follow-up results 2 years from baseline. Mothers of 144 mother-child dyads (ADHD according to DSM-IV) were examined for eligibility (T1) and randomised to 12 weeks of intensive multimodal treatment comprising pharmacotherapy and DBT-based cognitive behavioural group psychotherapy (TG, n = 77) or clinical management comprising non-specific counselling (CG, n = 67) for Step 1 (concluded by T2). Subsequently, all dyads participated in 12 weekly PCT sessions for Step 2 (concluded by T3). In Step 3, participants received maintenance treatments for 6 months (concluded by T4). At 24 months after baseline (T5), we performed follow-up assessments. The primary endpoint was child ADHD/ODD score (observer blind rating). Outcomes at T5 were evaluated using ANCOVA. Assessments from 101 children and 95 mothers were available at T5. Adjusted means (m) of ADHD/ODD symptoms (range 0-26) in children did not differ between TG and CG (mean difference = 1.0; 95% CI 1.2-3.1). The maternal advantage of TG over CG on the CAARS-O:L ADHD index (range 0-36) disappeared at T5 (mean difference = 0.2; 95% CI - 2.3 to 2.6). Sensitivity analyses controlling for medication and significant predictors of follow-up participation showed unchanged outcomes. Within-group outcomes remained improved from baseline. At the 24-month follow-up, TG and CG converged. The superiority of intensive treatment regarding maternal symptoms disappeared. In general, cross-generational treatment seems to be effective in the long term. (BMBF grant 01GV0605; registration ISRCTN73911400).

Multimodal treatment of children with ADHD often includes parent-child training (PCT). However, due to the high heritability, parents of children with ADHD are frequently also affected by the disorder, which is likely to constitute a significant barrier to successful treatment of the child. This secondary analysis of our randomized controlled multicentre AIMAC trial (ADHD in mothers and children) investigates whether children's outcomes following parent-child training in combination with maternal ADHD treatment depend on maternal symptom improvement. In a first step focusing on treatment of maternal ADHD, 144 mothers of mother-child dyads were randomized to multimodal ADHD treatment (group psychotherapy plus methylphenidate) or clinical management (mainly supportive counselling). After 12 weeks (T2), a 12-week PCT program (T2-T3) for all mother-child dyads was added to treat children's ADHD. Maternal symptomatology (CAARS-O:L; SCL-90-R) and children's externalizing symptoms (ADHD-ODD Scale, SDQ) were repeatedly assessed (T1 = baseline, T2, T3). Effects of changes in maternal symptomatology (T1-T2) on the change in children's symptom scores (T1-T3) were analysed using a general linear model, controlling for baseline scores, study centre, and maternal treatment group. 125 mother-child dyads were analysed. Mothers showed significant improvements in ADHD symptoms and overall psychopathology [CAARS-O:L ADHD index: mean - 3.54, SE 0.74 p < 0.0001; SCL-90-R Global Severity (GS): mean - 11.03, SE 3.90, p = 0.0056]. Although children's externalizing symptoms improved significantly (ADHD-ODD Scale: mean - 4.46, SE 0.58, p < 0.0001), maternal improvement had no effect on children's outcomes after Bonferroni-Holm correction for multiple testing. The findings do not support our hypothesis that children's outcomes following PCT for ADHD depend on maternal symptom improvements.Trial register CCT-ISRCTN73911400.

Atypical neuroleptics have enriched our treatment programmes, especially in childhood and adolescent schizophrenia. This article reviews the use of atypical neuroleptics in children and adolescents with schizophrenic disorder. It considers the receptor binding profile and pharmacological properties, indications, side effects, clinical applications and trials of atypical neuroleptics in comparison to the classical neuroleptic haloperidol in adolescent schizophrenia. Special emphasis is placed on the most common atypical neuroleptics clozapine, olanzapine and risperidone since most studies are carried out with these compounds, especially with clozapine. More clinically controlled trials have to be conducted since only one was performed so far. The place of the atypical neuroleptics is discussed and further studies are necessary in order to differentiate the indications tested so far and to find out if the spectrum of indications can be broadened.

The study explores the common clinical impression and previously reported finding by Hebebrand et al. (7) of reduced body weight in male children and adolescents with Asperger's disorder (AD). Body weight and height of 36 consecutively admitted male patients with AD were retrospectively assessed for the calculation of body mass indices (BMI, kg/m2). The BMIs were transformed to percentile ranks and plotted into BMI-centiles representative for the German population. In addition, comorbid psychopathology was assessed to explore a possible relationship between associated psychopathology and body weight. The mean BMI-centile of all patients was 34.7 +/- 31.8 and, thus, differed significantly from the mean centile of an age- and gender-matched psychiatric control group, which was 52.7 +/- 28.3. Thirteen patients had a BMI below the 10th centile and five even below the third. Three of the latter presented with disturbed eating behaviour. Altogether four patients showed disturbed eating behaviour. They had a significantly lower mean BMI-centile than the rest of the group. The BMI-centiles of patients with other additional psychopathology did not differ significantly from the mean percentile of the whole cohort. The results clearly show an increased risk for underweight and disturbed eating behaviour in patients with Asperger's disorder which should be evaluated in further studies.

Perceived and ideal body image were analysed in 36 inpatients with Anorexia Nervosa (AN) and 18 control patients (age 11-23 years). A computer-based image distortion technique allowed distortion of the whole body and of body parts. Subjects rated their own image. A body perception index (BPI) was calculated by dividing estimated dimension with real dimension. There was no general overestimation of body dimensions in AN patients in comparison to controls but AN patients more often under- or overestimated their body dimensions. Control patients showed a significant lower ideal BPI than AN patients, whose ideal body shape was similar to the observed body shape. Profile analyses of the body part estimation procedure revealed significant differences between groups in the ideal body shape at the body regions thigh, hip, waist and chest with control patients again showing a lower BPI.

The influence of different diagnostic approaches on familial aggregation of spelling disability was investigated in three studies. In the first study, in a sample of 32 dyslexic children and their families, we found significantly increased rates of spelling-disabled sibs and parents by applying the IQ-discrepancy criterion. There was no evidence for the assumption that IQ-discrepancy and low achievement criteria define different subgroups of spelling disorder regarding familial aggregation. In the second study, in a sample of 79 adults, it could be demonstrated that questionnaire data can be used as an appropriate method to classify adult probands as spelling disabled with a correct classification rate above 87%. In the third study, a subgroup of dyslexic boys could be characterized by a lack of the N1-component in visual evoked potentials which was most prominent in those boys whose spelling scores were more than 1.5 standard deviations below their intelligence level. This subgroup could be interesting also for genetic research.

Pattern reversal visually evoked potentials were examined in a group of 16 boys with developmental dyslexia and 17 controls matched for sex, age and intelligence. Delineation of hypothesis was done with an independent pilot study. Wave form differences between groups could be observed over the left central lead in the pilot and replication study. Only 44% of the dyslexies showed a negative component between 110 and 215 ms after stimulus onset in comparison to more than 80% of the controls. The lack of this component was most prominent in dyslexies whose spelling scores were more than 1.5 standard deviations below their intelligence score.
