Does diagnosis affect the predictive accuracy of risk assessment tools for juvenile offenders: Conduct Disorder and Attention Deficit Hyperactivity Disorder

Studies have suggested an increased risk of criminality in juveniles if they suffer from co-morbid Attention Deficit Hyperactivity Disorder (ADHD) along with Conduct Disorder. The Structured Assessment of Violence Risk in Youth (SAVRY), the Psychopathy Checklist Youth Version (PCL:YV), and Youth Level of Service/Case Management Inventory (YLS/CMI) have been shown to be good predictors of violent and non-violent re-offending. The aim was to compare the accuracy of these tools to predict violent and non-violent re-offending in young people with co-morbid ADHD and Conduct Disorder and Conduct Disorder only. The sample included 109 White-British adolescent males in secure settings. Results revealed no significant differences between the groups for re-offending. SAVRY factors had better predictive values than PCL:YV or YLS/CMI. Tools generally had better predictive values for the Conduct Disorder only group than the co-morbid group. Possible reasons for these findings have been discussed along with limitations of the study.     

Methylphenidate and Interpersonal Relationships of Children with Attention Deficit Hyperactivity Disorder

Abstract: In order to clarify the effects of methylphenidate on interpersonal relationships of children with attention deficit hyperactivity disorder (ADHD), data from sociometric tests conducted in 28 classes to which ADHD children belonged was analyzed, comparing patients who had a history of methylphenidate treatment with those who had not. It was suggested that ADHD children with a history of methylphenidate treatment had more favorable votes and fewer unfavorable ones than those without it. However, there were more isolated children among ADHD children with methylphenidate treatment than in those without it. The results are discussed in the light of previous findings in the literature and a hypothesis for methylphenidate induced isolation is proposed.     

Attention Deficit Hyperactivity Disorder and Comorbid Anxiety: Practitioner Problems in Treatment Planning

Attention Deficit Hyperactivity Disorder, combined type, and anxiety have been shown to co-occur in children but specific treatments tailored to suit this combination of diagnoses have not yet been reported. This paper addresses the problem from the perspective of clinical practice with a focus on treatment planning and evaluation. Existing work in the published literature is examined. A pilot study designed to explore the suitability of a cognitive-behavioural family-based intervention for use in a child mental health service is presented. The results of the intervention revealed high levels of parent and child satisfaction although there was no change in the level of symptoms. The implications for treatment planning and for future group interventions are discussed with regard to parent psychopathology and the difficulty in generalising research findings to day-to-day clinical practice.     

Motor Activity in Adult Patients with Attention Deficit Hyperactivity Disorder

Objective

Hyperactivity is a core symptom of attention-deficit hyperactivity disorder (ADHD), but limited information is available on analysis of activity patterns in this disorder. The aim of the study was to analyze motor activity during daily living in adult patients with ADHD.

Methods

Patients (n=76) from the private psychiatric practice of two of the authors were recruited, and were compared to patients with other psychiatric disorders and to normal controls. Actigraphs were used to record motor activity for six days, with one minute intervals, and data were analysed using linear and non-linear mathematical methods.

Results

For short recording periods (300 minutes) the activity levels of ADHD patients do not differ from normal controls, but the autocorrelation (lag 1) is lower and Fourier analysis shows higher power in the high frequency range, corresponding to the period from 2-8 min. During recordings for six days there are no significant differences between ADHD patients and the control groups. The combined and inattentive subgroups differ only in the six days recordings. The Fourier analyses show that the combined type has lower power in the high frequency range, corresponding to the period from 4-8 hours, and in the analysis of rhythms the intra-daily variability is lower, compared to the inattentive type.

Conclusion

Adult ADHD patients do not show evidence of hyperactivity, but have levels of activity similar to normal controls. However, on several measures ADHD patients display altered activity patterns, indicating that the regulation of motor activity in this disorder is different from controls.     

Prevalence Rates of Attention Deficit/Hyperactivity Disorder in a School Sample of Venezuelan Children

A total of 1,535 4–12 year-old children were screened with the Conners’ rating scales, followed by diagnostic confirmation by the diagnostic interview schedule for children-IV-parent version. The prevalence of ADHD was estimated to be 10.03%, and only 3.9% of children had received medication for the treatment of ADHD symptoms. Prevalence rates and demographic profile of Venezuelan children with ADHD are very similar to those found in samples from other countries. Authorities need to develop public health policies to correctly identify and treat affected subjects. Furthermore, clinicians must actively search for children with ADHD in order to provide the best-available treatment.     

Attention Deficit Hyperactivity Disorder Like Behavioral Problems and Parenting Stress in Pediatric Allergic Rhinitis

Objective

Previous studies have reported comorbidity of attention deficit and hyperactivity disorder (ADHD) and allergic diseases. The current study investigated ADHD like behavioral symptoms and parenting stress in pediatric allergic rhinitis.

Methods

Eighty-seven children (6-13 years old) with allergic rhinitis and 73 age- and sex-matched children of control group were recruited. Diagnosis and severity assessments of allergic rhinitis were determined by a pediatric allergist. The Parenting Stress Index-Short Form (PSI-SF), ADHD Rating Scale (ARS), and Child Behavior Checklist (CBCL) were completed by their mothers.

Results

In the allergic rhinitis group, the total PSI-SF score (p<0.01), ARS score (p<0.01), the subscale scores of the CBCL including somatization, attentional problems and emotional instability (p=0.01; p<0.01; p<0.01) and prevalence of ADHD (p=0.03) were significantly higher than those of the control group. Among mothers of children with allergic rhinitis, those of children with comorbid ADHD demonstrated significantly higher parenting stress than those without comorbid ADHD (p<0.01). Parenting stress was correlated with severity of child''s allergic symptoms and the ARS total score (beta=0.50, p<0.01; beta=0.39, p<0.01). There was a significant correlation between allergic symptom severity and the ARS total score (B=8.4, SD=2.5, t=3.3, p<0.01).

Conclusion

This study demonstrated that ADHD symptoms were common in children with allergic rhinitis, and this factor increased parenting stress and disrupted the parent-child relationship. Routine evaluation and early management of ADHD symptoms in pediatric allergic rhinitis may benefit families of children with allergic rhinitis.     

Adult Attention Deficit Hyperactivity Disorder Identified by Neuropsychological Testing

The authors used neuropsychological tests to assess and classify adult patients with attention deficit hyperactivity disorder (ADHD) and controls. Four memory tests correctly classified 81% of subjects. The memory tests were: the auditory Consonant trigram test, the Benton Visual Retention test, the Rey Auditory Verbal Learning test, and the modified Diagnosticum für Cerebralschädigung. The patients scored lower than controls also in other tests sensitive to frontal lobe dysfunction. The results underpin the importance of neuropsychological testing in adult ADD, but also support notions of a working-memory deficit linked to a dysfunction in the prefrontal cortex in these patients.     

Comparison of Psychosocial Correlates in Primary School Age Children with Attention Deficit/ Hyperactivity Disorder- Combined Type, with and without Dysthymic Disorder

In this study, standardized assessments of maternal psychopathology, family functioning and marital adjustment were compared between 115 medication naïve, clinically referred primary school age children with Attention Deficit Hyperactivity Disorder combined type (ADHD-CT) alone and 29 children with comorbid dysthymic disorder (DD) and ADHD-CT. The mothers of children with ADHD-CT and DD reported higher rates of anxiety and depression than those of children with ADHD-CT alone. These results reinforce the need for early recognition of comorbid DD when working with children with ADHD-CT. Increased rates of maternal anxiety and depression in children with ADHD-CT and DD may contribute to the children’s symptoms, require specific psychological and/or medication treatments and careful ongoing monitoring of these specific treatments.     

Identification of children at risk of Attention Deficit/Hyperactivity Disorder

Background In many countries, the majority of children who have Attention Deficit/Hyperactivity Disorder (ADHD) are undiagnosed and there is limited recognition of child mental health problems in primary care. Teachers may be well placed to identify unrecognised children and to facilitate their referral to specialist services. Despite this, there has been limited intervention research addressing teacher identification of ADHD. This study aims to examine whether an educational intervention about ADHD for teachers improves their recognition of children at risk of ADHD. Method A before and after investigation of an educational intervention about ADHD for teachers took place in 6 primary schools (involving 96 class teachers and 2672 pupils). Teacher recognition was compared against a diagnostic algorithm for ADHD caseness that utilised both parent and teacher ratings. Changes in teacher recognition of children with probable ADHD, as well as predictors of recognition, were examined. Results Following the intervention, there was an increase in the proportion of children regarded by teachers as having probable ADHD. There was also improved agreement between teacher recognition and the diagnostic algorithm. Teacher views that a child had probable ADHD were based on both the severity of symptoms and the impact of these problems on the teacher and the class. Conclusions It is feasible to deliver an educational intervention addressing teacher identification of ADHD in routine practice. This was associated with an improvement in the ability of teachers to more accurately identify children at risk of ADHD. The provision of a brief educational intervention for teachers could assist in improving the identification of undiagnosed children with ADHD in the community.

Association between sensory modulation and sleep difficulties in children with Attention Deficit Hyperactivity Disorder (ADHD)

BackgroundSleep difficulties have been reported in up to 85% of children with Attention Deficit hyperactivity disorder (ADHD). Children with ADHD exhibit commonly sensory modulation difficulties (SMD) and experience more significant functional difficulties. Sleep difficulties have also been associated with SMD. The aim of this study was to evaluate whether SMD are associated with sleep difficulties in children with ADHD.MethodsWe assessed sleep difficulties using the Children's Sleep Habits Questionnaire, and SMD using the Short Sensory Profile (SSP) questionnaire. A total of 25 children with ADHD and atypical sensory profiles, 13 children with ADHD and typical sensory profiles and 38 children used as controls (all children aged 8–11 years) were included.ResultsSleep difficulties were detected in 86.4% of children with ADHD and atypical SSPs, as compared to 30.8% of children with ADHD and typical SSPs, and 16.7% of controls. A multivariate logistic regression revealed that children with ADHD and atypical SSPs had significantly increased odds for sleep difficulties as compared to controls (OR = 32.4; 95% CI 4.0–260.1, p = 0.001), while children with ADHD and typical SSPs were indistinguishable from controls. Suspected confounders (gender, age, mother's education, and stimulant therapy) did not contribute to sleep difficulties.ConclusionIn this pilot study, SMD were associated with sleep difficulties in children with ADHD.     

Attention Deficit Hyperactivity Disorder: New Ways of Working in Primary Care

Children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) and prescribed pharmacotherapy require ongoing regular follow-up for many years. Recent literature outlining the role of primary care in the ongoing medication monitoring of children and young people with ADHD is reviewed. We propose that a General Practitioner with a Specialist Interest (GPwSI) model could be developed in relation to ADHD to ensure that shared care arrangements between CAMHS and primary care for children with ADHD are in place. Clinical materials to support GPs in this new role are described.     

Memory Tests in Subgroups of Adult Attention Deficit Hyperactivity Disorder Reveals Simultaneous Capacity Deficit

Neuropsychological tests were used to evaluate different memory systems in the three subgroups of adult Attention Deficit Hyperactivity Disorder (ADHD) (n = 105) using analysis of means, factor analysis, and GLM analysis with covariance of gender, estimated IQ, and level of anxiety and depression measured with the Hospital anxiety and depression scale. A higher IQ level was found in the neuropsychological background tests for the predominantly inattentive subtype (ADD). In the memory tests the dual-task memory/simultaneous capacity tests “Brown-Peterson” Consonant Trigram and Benton Visual Retention Test (BVRT) were the most sensitive and were severely reduced in all three subgroups, but only the BVRT revealed a difference between the three ADHD groups. In learning and delayed recall measured with Rey Auditory Verbal learning test and modified Diagnosticum für Cerebralschädigung (mDCS), the Attention Deficit Disorder subgroup had the best learning and delayed capacity of the three groups. A good agreement was found between the interviewed DSM-IV-TR criteria, Conners CAARS S:S scale, and Wender WURS 25-item scales. Despite the difference in number of ADHD criteria for the three ADHD subgroups, the results in the neuropsychological memory tests indicate a severe reduction in all three subgroups of adult ADHD in simultaneous capacity.     

Association of SNAP-25 Gene Ddel and Mnll Polymorphisms with Adult Attention Deficit Hyperactivity Disorder

Objective

The synaptosomal-associated protein of 25 kDa (SNAP-25) gene is a presynaptic plasma membrane protein and an integral component of the vesicle docking and fusion machinery mediating secretion of neurotransmitters. Previously, several studies reported association between SNAP-25 and attention deficit hyperactivity disorder (ADHD). We investigated whether these SNAP-25 polymorphisms (MnlI T/G and DdelI T/C) were also associated with ADHD in the Turkish population.

Methods

Our study comprised unrelated 139 subjects who met DSM-IV criteria for ADHD and 73 controls and all were of Turkish origin. Genetic analyses were performed and patients were evaluated with Wender-Utah Rating Scale and Adult ADD/ADHD DSM IV-Based Diagnostic Screening and Rating Scale.

Results

SNAP-25 DdelI polymorphism was not associated with ADHD but there was a statistically significant difference between ADHD patients and controls for SNAP-25 MnlI polymorphism. For SNAP-25 MnlI polymorphism patients with G/G genotype of the SNAP-25 gene MnlI polymorphism had higher Wender-Utah scores and higher scores in the 1st and 3rd parts of adult ADD/ADHD Scale.

Conclusion

We detected a significant association of the MnlI polymorphism in our ADHD sample which was similar to previous findings. Our study also revealed that SNAP-25 MnlI polymorphism was also associated with symptom severity of ADHD. This study is also, the first report on the association of SNAP-25 with ADHD in the Turkish population.     

Methylphenidate-induced improvements of various measures of attention in adults with Attention Deficit Hyperactivity Disorder

Summary. The present study examined the effect of the stimulant medication methylphenidate (MPH) on attentional functioning of adults with ADHD. Sixteen adults with a diagnosed ADHD without comorbidity were assessed twice, at baseline off MPH and following MPH treatment. The assessment battery consisted of reaction time tasks of low complexity, including measures of alertness – subdivided into tonic and phasic alertness, vigilance, divided attention, flexibility and such aspects of selective attention as including focused attention, inhibition and integration of sensory information. In addition, 16 healthy participants who were matched to adults with ADHD according to sex, age, education level and intellectual functions were also assessed twice using the same test battery. The results of the present study suggest that adults with ADHD off stimulant medication are seriously impaired in various components of attention including vigilance, divided attention, selective attention and flexibility. These impairments of attention were observed primarily in regard to reaction time and its variability. Treatment of adults with ADHD using individually tailored doses of MPH has a positive effect on measures of alertness, vigilance, selective attention, divided attention and flexibility. However, even on MPH adults with ADHD displayed considerable deficits in vigilance and integration of sensory information. The present findings indicate that adults with ADHD are not differentially impaired in attentional processes but may suffer from a more global deficit of attention. Although MPH treatment has been found to be effective in the treatment of the attention deficit of adults with ADHD, additional treatment appears to be necessary.     

Oppositional Defiant and Conduct Disorder Behaviors in Boys With Autism Spectrum Disorder With and Without Attention-Deficit Hyperactivity Disorder Versus Several Comparison Samples

We compared disruptive behaviors in boys with either autism spectrum disorder (ASD) plus ADHD (n = 74), chronic multiple tic disorder plus ADHD (n = 47), ADHD Only (n = 59), or ASD Only (n = 107). Children were evaluated with parent and teacher versions of the Child Symptom Inventory-4 including parent- (n = 168) and teacher-rated (n = 173) community controls. Parents rated children in the three ADHD groups comparably for each symptom of oppositional defiant disorder (ODD) and conduct disorder. Teacher ratings indicated that the ASD + ADHD group evidenced a unique pattern of ODD symptom severity, differentiating them from the other ADHD groups, and from the ASD Only group. The clinical features of ASD appear to influence co-morbid, DSM-IV-defined ODD, with implications for nosology.     

Attention Deficit Hyperactivity Disorder (ADHD) and the Criminal Law1

Attention Deficit Hyperactivity Disorder (ADHD) has been identified as significantly over-represented in the prison population and being a likely precipitant to engagement in criminal conduct. There should be little surprise in this fact, as impulsivity, inattentiveness to instructions, inability to retain information and limitations in the ability to think rationally through the likely consequences of actions have long been recognised as criminogenic factors. This article adds to the literature on ADHD and the criminal law. It reviews the history of ADHD diagnosis and treatment and scrutinises important English, Australian, New Zealand and Canadian judgments, in particular at appellate level, in which the relevance of ADHD to criminal offending has been evaluated. It notes the vulnerability of persons with ADHD in the context of being interviewed by police on suspicion of having committed criminal offences, it raises issues related to the fitness to stand trial of accused persons with ADHD and it identifies a need for forensic psychiatrists and psychologists to give particular attention in their reports and evidence to an assessment of the extent and nature of an offender’s ADHD symptomatology and whether it played a causative or influential role in the person’s engagement in criminal conduct, as well as to whether symptomatology is likely to be worsened by imprisonment or to render the offender especially vulnerable in a custodial environment.     

Adherence with Electronic Monitoring and Symptoms in Children with Attention Deficit Hyperactivity Disorder

Objective

The primary aim of this study was to compare electronic monitoring with other measures of adherence to Osmotic-controlled Release Oral delivery System methylphenidate in children with attention-deficit hyperactivity disorder (ADHD). The secondary aim was to analyze the relationships between adherence and clinical factors, including ADHD symptoms.

Methods

Thirty-nine children diagnosed with ADHD were monitored for adherence to medication over the course of eight weeks. Medication adherence was assessed using the Medication Event Monitoring System (MEMS), which is a bottle cap with a microprocessor that records all instances and times that the bottle is opened; patient self-report; clinician rating; and pill count. Information, including demographic and clinical characteristics, symptom rating scale, and psychological test results, were also collected. The relationships between adherence and clinical factors, including ADHD rating scores of baseline and of the changes, were assessed.

Results

The rate of non-adherence measured by the MEMS was found to be 46.2%, which was considerably higher than those of the patient self-report (17.9%), clinician rating (31.7%), and pill count (12.8%) of non-adherence. The rate of adherence measured by the MEMS was not significantly associated with baseline symptom severity or symptom changes over the eight weeks, although non-adherent group showed more severe baseline symptoms and inferior improvement.

Conclusion

Adherence as measured by the MEMS showed a discrepancy with other measures of adherence in patients with ADHD. The symptom severity and level of improvement were not related to adherence with MEMS. Further studies are needed to evaluate the variables that may impact medication adherence in children with ADHD.
