Stigma in attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder (ADHD) is a frequently diagnosed disorder in child- and adulthood with a high impact affecting multiple facets of social life. Therefore, patients suffering from ADHD are at high risk to be confronted with stigma, prejudices, and discrimination. A review of the empirical research in the field of ADHD with regard to stigma was performed. The findings of investigations in this field were clustered in different categories, including stigma in children with ADHD, stigma in adults with ADHD, stigma in relatives or in people close to a patient with ADHD, and the influence of stigma on authorities' attitudes toward patients with ADHD. Variables identified to contribute to stigma in ADHD are public's uncertainty concerning the reliability/validity of an ADHD diagnosis and the related diagnostic assessment, public's perceived dangerousness of individuals with ADHD, socio-demographical factors as age, gender, and ethnicity of the respondent or the target individual with ADHD, stigmatization of ADHD treatment, for example public's skepticism toward ADHD medication and disclosure of diagnostic status as well as medication status of the individual with ADHD. The contribution of stigma associated with ADHD can be conceptualized as an underestimated risk factor, affecting treatment adherence, treatment efficacy, symptom aggravation, life satisfaction, and mentally well-being of individuals affected by ADHD. Public as well as health professionals' concepts about ADHD are highly diverse, setting individuals with an ADHD diagnosis at greater risk to get stigmatized.     

ADHD and comorbid conduct problems among adolescents: associations with self-esteem and substance use

Attention-deficit/hyperactivity disorder (ADHD) is a common child and adolescent disorder that is associated with negative outcomes (e.g., emotional and behavioral problems, substance use) and is often comorbid with Conduct Problems (CP). Research findings are mixed as to whether youth with ADHD alone or comorbid ADHD/CP suffer from low self-esteem. Research has also shown links between low self-esteem and ADHD (alone and with CP) with substance use; yet, no research has examined the links between self-esteem and substance use in adolescents with ADHD and CP. The current study examined the relation between ADHD with and without comorbid CP and self-esteem, and whether self-esteem moderated the relation between ADHD and ADHD/CP with substance use among adolescents. We hypothesized that adolescents with comorbid ADHD/CP would experience lower self-esteem than adolescents with ADHD alone or with neither disorder and that self-esteem would moderate the association between ADHD, CP, and substance use. Participants were 62 adolescents who completed the laboratory-based study with a parent. Results suggested that adolescents with comorbid ADHD and CP had significantly lower self-esteem than adolescents with ADHD alone or neither disorder. Self-esteem was not significantly different for adolescents with ADHD alone versus those in the control group. There was one marginally significant interaction between ADHD and self-esteem predicting substance use, such that individuals with comorbid ADHD/CP who also had low self-esteem tended to use more substances. Results have implications for treatments that target adolescents with ADHD and comorbid CP, as these adolescents are at risk for many deleterious outcomes.     

ADHD in acute care psychiatric inpatients

Attention-deficit hyperactivity disorder (ADHD) is a neurocognitive disorder characterized by symptoms of inattention, impulsivity and motor hyperactivity. The worldwide prevalence of ADHD, in the general adult population, has been estimated to be 2.8%. Patients with ADHD have a high incidence of comorbidity with other psychiatric disorders. Those with a psychiatric disorder as well as ADHD have more psychosocial difficulties than those without ADHD. Despite knowing that ADHD is often comorbid with other psychiatric diagnoses, there are currently no studies elucidating the prevalence of ADHD in the inpatient psychiatric population, nor is there significant information about its impact. The lack of research into this topic suggests more needs to be done in the field of adult ADHD, especially in the inpatient psychiatric population and with respect to impairment in patient function. Knowing the prevalence of ADHD and its impact on quality of life in adult inpatients will help lay the groundwork for effective screening and management. The purpose of this study was to understand the prevalence rates of ADHD among psychiatric acute care inpatients. Other objectives included comparing the quality of life and functioning between patients with a primary psychiatric diagnosis and ADHD (treated or untreated) versus those with a primary psychiatric diagnosis and no ADHD. Thirty-three (N = 31) psychiatric inpatients were screened using the Adult ADHD Self-Report Scale. Those that screened positive for ADHD received a full diagnostic assessment for ADHD. All patients completed the Weiss Functional Impairment Rating Scale (WFIRS) to assess level of functioning and a Clinical Global Impression of Severity/Improvement Scale (on admission and discharge). Demographic information was also obtained. Of the 31 patients analyzed, 12 had a diagnosis of ADHD (36.4%). The participants diagnosed with ADHD scored significantly higher on the WFIRS, suggesting decreased functioning compared to patients without comorbid ADHD. Patients with ADHD also scored significantly higher in the individual domains of this rating scale, suggesting impairment in family, work and social functioning as well as decreased life-skills, poor self-concept and increased risk-taking behavior. In this sample, the prevalence of ADHD is significantly higher among acute care psychiatric inpatients than in the general population. Patients with concomitant ADHD suffer more functional impairment than those without. These findings merit further investigation into the value of routine screening and patient-specific treatment of ADHD in this patient population.     

Association of ADHD with reactive and proactive violent behavior in a forensic population

ADHD is associated with social problems and aggressive behavior. As hyperactive-impulsive traits are core symptoms of ADHD, it has been hypothesized that reactive-impulsive violence is more likely related to ADHD psychopathology than proactive-instrumental violence. One hundred and twenty-seven adult violent offenders participated in the study. Diagnosis of ADHD and ratings of reactive and proactive features of the committed crimes were performed using standardized instruments. According to DSM-IV, 16.5% subjects fulfilled diagnostic criteria for ADHD, 23.6% were diagnosed as ADHD in partial remission, and 59.8% had no ADHD. Univariate analyses revealed higher reactive violence ratings in both ADHD groups when compared to subjects without ADHD, whereas the opposite was found regarding proactive violence ratings. Using multivariate analyses of variance controlled for age, gender and comorbid substance use disorders, childhood ADHD psychopathology and current ADHD significantly increased the risk of reactive violence and decreased the risk of proactive violence. Significant impact of male gender on proactive violence was found. The findings suggest that ADHD is associated with reactive but not proactive violence in aggressive offenders.     

Hypersomnia with ADHD: a possible subtype of narcolepsy type 2

Patients with attention deficit/hyperactivity disorder (ADHD) suffer from hypersomnia; indeed, we have often encountered ADHD patients that fulfill the diagnostic criteria for narcolepsy type 2 (NA 2). Because not all patients with NA 2 carry the HLA-DQB1*06:02 allele, which is closely associated with narcolepsy type 1 (NA 1), NA 2 is believed to be heterogeneous. To reveal the contribution of ADHD in hypersomnia, we studied the characteristics of hypersomnia patients with ADHD, especially those diagnosed with NA 2. Participants were 77 of 185 consecutive outpatients who were diagnosed with NA 2 or idiopathic hypersomnia. We investigated sleep variables in (a) participants with hypersomnia with/without ADHD and (b) patients with NA 2 with/without ADHD and those with/without the DQB1*06:02 allele. The proportion of those diagnosed with NA 2 was higher in hypersomnia patients with ADHD compared to those without ADHD. None of the NA 2 patients with ADHD carried the narcolepsy-specific DQB1*06:02 allele. These patients with NA 2 with ADHD exhibited short REM latencies on the MSLT (similarly to DQB1*06:02-positive patients with NA 2 without ADHD), but less REM-related phenomena than patients with NA 2 without ADHD. Hypersomnia patients with ADHD tended to show short REM latencies, and fulfilled NA 2 diagnostic criteria in the absence of the DQB1*06:02 allele, suggesting a different etiology from NA 1. These findings support the hypotheses of noradrenergic dysregulation and delayed brain maturation that have been proposed for the pathophysiology of ADHD.

     

How do children with and without ADHD talk about frustration?: Use of a novel emotion narrative recall task

Children with attention-deficit/hyperactivity disorder (ADHD) experience difficulties related to emotional reactivity and regulation. The current study examines differences in the emotional reactivity and regulation of children with and without ADHD in the context of their real-life experiences of negative emotion using a novel ecologically valid methodology. Eighty-three 8–12-year-old children (46 ADHD, 38 non-ADHD) participated in the study. Children completed the negative emotion narrative recall task, a novel task whereby children provided a narrative recall of a real-life event where they experienced negative emotion. ANCOVA indicated children with ADHD recalled significantly more overall frustration and intense frustration than children without ADHD. Children with ADHD exhibiting more negative emotional reactivity while recalling negative emotions than children without ADHD. The current study suggests that children with ADHD are uniquely impacted by negative emotional experiences and represents an important step in understanding the emotional reactivity and regulation of children with ADHD.     

Comorbidity and continuity of attention deficit hyperactivity disorder (ADHD) from childhood to adolescence in Turkey

The aim of this study was to examine clinical outcomes, psychiatric comorbidity and neuropsychological characteristics in Turkish adolescents with an attention deficit hyperactivity disorder (ADHD) diagnosis in childhood. A total of 45 children with ADHD diagnosis and 28 children with a psychiatric diagnosis other than ADHD in a 1-year cohort of 7–10-year-olds were reevaluated 6 years later using Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version and Wechsler Intelligence Scale for Children-Revised and Stroop Test TBAG version. This study shows that the clinical outcomes and the comorbidity patterns for ADHD from childhood to adolescence in Turkey are similar to reported rates in the Western countries. In the ADHD group, 75.6 % still has impairing ADHD symptoms and 46.6 % has comorbid psychiatric disorders. The main difference is anxiety disorders being the most common comorbid disorders (37.8 %) in Turkish ADHD youth. These findings stress the high comorbidity associated with ADHD and support the importance of assessment and treatment for ADHD and comorbidities during adolescence.     

Parental efficacy and child behavior in a community sample of children with and without attention-deficit hyperactivity disorder (ADHD)

Most studies of attention-deficit hyperactivity disorder (ADHD) youth have obtained data from the perspective of either children or parents, but not both simultaneously. The purpose of this study was to examine child and parent perspectives on parenting in a large community-based sample of children with and without ADHD. We identified children in grades 4?C6 and their parents through surveys administered to a random sample of public schools. We used multivariable logistic regression to determine independent associations between child and parent characteristics and the presence of ADHD while controlling for covariates and clustering by school. Sufficient data were achieved for 2,509 child/parent dyads. Ten percent of youths (n?=?240) had been diagnosed with ADHD. Compared with those without ADHD, those with ADHD were more commonly male (67.9 vs. 48.0?%, p?<?.001) and age 12 or over (16.3 vs. 10.3?%). After adjusting for covariates and clustering, compared to children without ADHD, children with ADHD were significantly more likely to report lower self-regulation (OR?=?0.68, 95?% CI?=?0.53, 0.88) and higher levels of rebelliousness (OR?=?2.00, 95?% CI?=?1.52, 2.69). Compared with parents whose children did not have ADHD, parents of children with ADHD rated their overall parental efficacy substantially lower (OR?=?0.23, 95?% CI?=?0.15, 0.33). However, child assessment of parenting style was similar by ADHD. Despite the internal challenges community-based youth with ADHD face, many parents of ADHD youth exhibit valuable parental skills from the perspective of their children. Feedback of this information to parents may improve parental self-efficacy, which is known to be positively associated with improved ADHD outcomes.     

A prospective look at substance use and criminal behavior in urban ADHD youth: what is the role of maltreatment history on outcome?

Children with attention-deficit/hyperactivity disorder (ADHD) are at heightened risk of antisocial behavior during adolescence/early adulthood. Here, we characterize the antisocial outcomes of a sample of urban, lower-socioeconomic-status, ethnically diverse ADHD youth and investigate the impact of maltreatment history on criminal and substance use disorder (SUD) outcomes. Ninety-eight participants diagnosed with ADHD in childhood were re-assessed 10 years later and compared with controls. Regression analyses investigated the effect of maltreatment on antisocial outcomes among four groups based on ADHD and maltreatment status. ADHD subjects and controls did not differ in rates of arrest, conviction, incarceration, or recidivism. ADHD youth were younger at their first arrest with higher rates of SUDs when compared to controls. Controls and ADHD subjects with maltreatment had significantly higher rates of SUDs compared to the no-ADHD/no-maltreatment group. Only ADHD youth with maltreatment had significantly higher rates of arrest than the reference group. In contrast to prior studies, ADHD youth did not differ from controls on most measures of antisocial behavior. Maltreatment increased the rate of arrest only among ADHD youth, though increased the rate of SUD for ADHD youth and controls. This suggests that ADHD youth, in the absence of maltreatment, are at no greater risk of SUDs or arrest than controls without maltreatment.     

Steroid sulfatase is a potential modifier of cognition in attention deficit hyperactivity disorder

Deletions encompassing the X-linked STS gene (encoding steroid sulfatase) have been observed in subjects with neurodevelopmental disorders, including attention deficit hyperactivity disorder (ADHD). Recently, two single nucleotide polymorphisms (SNPs) within STS (rs12861247 and rs17268988) have been reported to be associated with ADHD risk and inattentive symptoms in ADHD, respectively. Using a UK sample of ADHD subjects (aged 5-18 years), we tested the hypothesis that rs12861247 is associated with ADHD risk using a case-control approach (comparing 327 ADHD cases with 358 male controls from the Wellcome Trust Case Control Consortium). Using a subset of males from the ADHD sample, we also examined whether variation within STS is associated with symptomatology/cognitive function in ADHD. We then tested whether SNPs associated with cognitive function in ADHD were also associated with cognitive function in healthy male subjects using a German sample (n = 143, aged 18-30 years), and whether STS was expressed in brain regions pertinent to ADHD pathology during development. We did not replicate the previously identified association with rs12861247. However, in ADHD males, variation at rs17268988 was associated with inattentive symptoms, while variation within STS was significantly associated with performance on three cognitive measures. Three SNPs associated with cognitive function in ADHD males were not associated with cognitive function in healthy males. STS was highly expressed in the developing cerebellar neuroepithelium, basal ganglia, thalamus, pituitary gland, hypothalamus and choroid plexus. These data suggest that genetic variants affecting STS expression and/or activity could influence the function of brain regions perturbed in ADHD.     

A systematic review of circadian function,chronotype and chronotherapy in attention deficit hyperactivity disorder

Reports of sleep disturbances in attention deficit hyperactivity disorder (ADHD) are common in both children and adults; however, the aetiology of such disturbances is poorly understood. One potentially important mechanism which may be implicated in disrupted sleep in ADHD is the circadian clock, a known key regulator of the sleep/wake cycle. In this systematic review, we analyse the evidence for circadian rhythm changes associated with ADHD, as well as assessing evidence for therapeutic approaches involving the circadian clock in ADHD. We identify 62 relevant studies involving a total of 4462 ADHD patients. We find consistent evidence indicating that ADHD is associated with more eveningness/later chronotype and with phase delay of circadian phase markers such as dim light melatonin onset and delayed sleep onset. We find that there is evidence that melatonin treatment may be efficacious in addressing ADHD-related sleep problems, although there are few studies to date addressing other chronotherapeutic approaches in ADHD. There are only a small number of genetic association studies which report linkages between polymorphisms in circadian clock genes and ADHD symptoms. In conclusion, we find that there is consistent evidence for circadian rhythm disruption in ADHD and that such disruption may present a therapeutic target that future ADHD research might concentrate explicitly on.     

Hair trace element concentrations in autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD)

BackgroundThe existing data demonstrate that alteration of trace element and mineral status in children with neurodevelopmental disorders including ASD and ADHD. However, comparative analysis of the specific patterns of trace element and mineral metabolism in children with ASD and ADHD was not performed. Therefore, the primary objective of the present study was to assess hair trace element and mineral levels in boys with ADHD, ASD, as well as ADHD with ASD.MethodsBoys with ADHD (n = 52), ASD (n = 53), both ADHD and ASD (n = 52), as well as neurotypical controls (n = 52) were examined. Hair analysis was performed using inductively-coupled plasma mass-spectrometry.ResultsThe obtained data demonstrate that hair Co, Mg, Mn, and V levels were significantly reduced in children with ADHD and ASD, and especially in boys with ADHD + ASD. Hair Zn was found to be reduced by 20% (p = 0.009) only in children with ADHD + ASD as compared to healthy controls. Factor analysis demonstrated that ASD was associated with significant alteration of hair Co, Fe, Mg, Mn, and V levels, whereas impaired hair Mg, Mn, and Zn content was also significantly associated with ADHD. In regression models hair Zn and Mg were negatively associated with severity of neurodevelopmental disorders. The revealed similarity of trace element and mineral disturbances in ASD and ADHD may be indicative of certain similar pathogenetic features.ConclusionThe obtained data support the hypothesis that trace elements and minerals, namely Mg, Mn, and Zn, may play a significant role in development of both ADHD and ASD. Improvement of Mg, Mn, and Zn status in children with ASD and ADHD may be considered as a nutritional strategy for improvement of neurodevelopmental disturbances, although clinical trials and experimental studies are highly required to support this hypothesis.     

Atomoxetine response in the inattentive and combined subtypes of attention deficit hyperactivity disorder: a retrospective chart review

The DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders, 1994, American Psychiatric Association) describes attention deficit hyperactivity disorder (ADHD) as a heterogeneous disorder; providing diagnostic criteria for three subtypes: hyperactive/impulsive (ADHD/HI), inattentive (ADHD/I), and combined type (ADHD/C). Differences among the subtypes are well defined, but there may be also differences in terms of treatment responses. The aim of this study is to assess the responses of ADHD/I and ADHD/C to atomoxetine treatment. The medical records of the January–June 2012 term, first time referrals to outpatient clinic, were reviewed, and 37 ADHD diagnosed primary school age children (18 ADHD/I, 19 ADHD/C) that were treated with atomoxetine were determined. Thirty-five of them who completed 8 weeks of treatment duration were recruited for the study. The children with an ADHD medication use history in 2 months time prior to onset of treatment and/or the children receiving additional psychopharmacologic treatment to atomoxetine were excluded. Baseline and eighth week assessment, records were evaluated. Efficacy assessments included Turgay DSM-IV ADHD Screening and Rating Scale parent and teacher forms (T-DSM-IV) and Clinical Global Impression Scale-Severity and Improvement subscales. Safety assessments included laboratory and body weight assessments, ECG, heart rate, and blood pressure evaluations (baseline and eighth week) along a scale filled by the parents at the eighth week to review side effects. Atomoxetine was found to be effective in both ADHD/I and ADHD/C groups. Atomoxetine also decreased the opposition defiance subscale scores of T-DSM-IV (both parent and teacher forms), whereas it was not found to make statistically significant difference in the conduct disorder subscale scores. Mean difference in 8-week time in T-DSM-IV hyperactivity subscale and total scores of parent and teacher forms; inattention subscale scores of only parent forms and the CGI- severity subscale scores; differed significantly among the ADHD/I and ADHD/C groups; that ADHD/C types responded better to medication. Results of this study revealed that atomoxetine is effective both in ADHD/I and ADHD/C subtypes. ADHD/C types may be responding better to atomoxetine treatment than the ADHD/I subtypes.     

Protopathic stimulant use among children with symptoms of ADHD

The purpose of the current study was to examine protopathic stimulant use among children with the symptoms of ADHD but do not have a diagnosis of ADHD. Protopathic or prodromal stimulant use refers to the use of stimulants by children with the symptoms of ADHD prior to a diagnosis of ADHD. In the current study, we examined children with the symptoms of ADHD who received stimulant treatment across time and with respect to several background variables. Our results indicate that these children who receive stimulant treatment without a diagnosis of ADHD are significantly more like to be eventually diagnosed with ADHD than not. Results also indicate that these children who receive stimulant treatment but do not yet have a diagnosis of ADHD are significantly more likely to have insurance that does not pay for diagnostic procedures. These results are discussed in view of treatment.     

ADHD symptoms in healthy adults are associated with stressful life events and negative memory bias

Stressful life events, especially Childhood Trauma, predict ADHD symptoms. Childhood Trauma and negatively biased memory are risk factors for affective disorders. The association of life events and bias with ADHD symptoms may inform about the etiology of ADHD. Memory bias was tested using a computer task in N = 675 healthy adults. Life events and ADHD symptoms were assessed using questionnaires. The mediation of the association between life events and ADHD symptoms by memory bias was examined. We explored the roles of different types of life events and of ADHD symptom clusters. Life events and memory bias were associated with overall ADHD symptoms as well as inattention and hyperactivity/impulsivity symptom clusters. Memory bias mediated the association of Lifetime Life Events, specifically Childhood Trauma, with ADHD symptoms. Negatively biased memory may be a cognitive marker of the effects of Childhood Trauma on the development and/or persistence of ADHD symptoms.     

Childhood and persistent ADHD symptoms associated with educational failure and long-term occupational disability in adult ADHD

Few studies have examined the impact of childhood attention deficit hyperactivity disorder (ADHD) symptoms on adult ADHD functional outcomes. To address this issue dimensionally, ADHD symptoms in childhood and adulthood and their relation to educational deficits and work disability are studied in a clinical sample of adult patients with previously untreated ADHD. About 250 adults diagnosed systematically with ADHD according to DSM-IV were prospectively recruited. Primary outcomes were high school dropout and being out of the work last year. Childhood ADHD symptoms, sex differences, comorbidities of other mental disorders, and adult ADHD symptoms were examined by historical data, clinician interviews, and questionnaires. High levels of ADHD symptom severity in childhood were related to dropping out of high school [odds ratio (OR) = 3.0], as were higher numbers of hyperactive–impulsive symptoms in childhood. Significantly, more women than men were long-term work disabled (OR = 2.0). After adjusting for age and gender, persisting high levels of ADHD inattention symptoms in adulthood (OR = 2.5), number of comorbid disorders, and particularly anxiety disorders were significantly related to long-term work disability. Childhood hyperactive–impulsive symptoms and overall severity of childhood ADHD symptoms were associated with high school dropout rates; however, persisting ADHD inattention symptoms and comorbid mental disorders in adulthood were more correlated to occupational impairment. These findings underline proposals for studies on early recognition and interventions for ADHD and psychiatric comorbidity. They further suggest that inattentive symptoms be a focus of adult ADHD treatment and that workplace interventions be considered to prevent long-term work disability.     

Features of the power spectra of the main EEG rhythms in children with different types of attention deficit hyperactivity disorder

As a result of the examination of a group of 9- to 12-year-old children with the combined type of attention deficit hyperactivity disorder (ADHD), two variants of the clinical picture of ADHD were identified: the residual organic variant (ADHD RO) and the idiopathic variant (ADHD IP). The EEG power spectra in the main frequency ranges were studied with the eyes closed and open. The greatest intergroup differences in the power spectra were observed in the θ-band in the forntocentral and occipital derivations. In the frontocentral divisions of the cortex, the maximal values were observed in the group of ADHD RO children, whereas the highest spectral power values were observed in ADHD IP children in the occipital derivations. No statistically significant differences in the α-band spectral power between healthy subjects and ADHD schoolchildren from either group were obtained. Thus, the studies showed that these two ADHD variants have certain neurophysiological differences, which should be considered when therapeutic modalities are to be selected.     

Attention Deficit Hyperactivity Disorder in Australian Adults: Prevalence,Persistence, Conduct Problems and Disadvantage

Background

The Prevalence and persistence of ADHD have not been described in young Australian adults and few studies have examined how conduct problems (CP) are associated with ADHD for this age group. We estimate lifetime and adult prevalence and persistence rates for three categories of ADHD for 3795 Australian adults, and indicate how career, health and childhood risk factors differ for people with ADHD symptoms and ADHD symptoms plus CP.

Methodology

Trained interviewers collected participant experience of ADHD, CP, education, employment, childhood experience, relationship and health variables. Three diagnostic definitions of ADHD used were (i) full DSM-IV criteria; (ii) excluding the age 7 onset criterion (no age criterion); (iii) participant experienced difficulties due to ADHD symptoms (problem symptoms).

Results

Prevalence rates in adulthood were 1.1%, 2.3% and 2.7% for each categorization respectively. Persistence of ADHD from childhood averaged across gender was 55.3% for full criteria, 50.3% with no age criterion and 40.2% for problem symptoms. ADHD symptoms were associated with parental conflict, poor health, being sexually assaulted during childhood, lower education, income loss and higher unemployment. The lifetime prevalence of conduct problems for adults with ADHD was 57.8% and 6.9% for adults without ADHD. The greatest disadvantage was experienced by participants with ADHD plus CP.

Conclusion

The persistence of ADHD into adulthood was greatest for participants meeting full diagnostic criteria and inattention was associated with the greatest loss of income and disadvantage. The disadvantage associated with conduct problems differed in severity and was relevant for a high proportion of adults with ADHD. Women but not men with ADHD reported more childhood adversity, possibly indicating varied etiology and treatment needs. The impact and treatment needs of adults with ADHD and CP and the report of sexual assault during childhood by women and men with ADHD also deserve further study.     

Obsessive–compulsive adults with and without childhood ADHD symptoms

Obsessive–compulsive disorder (OCD) and attention-deficit and hyperactivity disorder (ADHD) frequently coexist. To understand whether childhood ADHD can increase the risk of OCD in adulthood and whether it influences the phenomenology of OCD, we investigated the symptoms of ADHD during childhood in obsessive–compulsive adults who had never been diagnosed as ADHD. Adults with OCD (n = 83) were given the Wender Utah Rating Scale (WURS), Yale–Brown Obsessive Compulsive Scale (Y-BOCS), Barratt Impulsiveness Scale-11 (BIS-11), Hamilton Depression Rating Scale-17 (HDRS-17) and Beck Anxiety Inventory (BAI). The prevalence of childhood ADHD symptoms was 40.9 % (n = 34) and that of adult ADHD was 16.9 % (n = 14). Patients with childhood ADHD symptoms had an earlier onset of OCD, higher scores of the BAI and BIS-11. The scores of the Y-BOCS and HDRS-17 did not differ between those having and not having childhood ADHD symptoms. Childhood history of ADHD symptoms is common in adult OCD patients who have never been diagnosed as ADHD. Childhood ADHD symptoms are associated with an earlier age of OCD, more severe anxiety and higher impulsiveness. Even remitted ADHD may be a risk factor for OCD in later life.
