Do SNPs of DRD4 gene predict adult persistence of ADHD in a Chinese sample?

The dopamine D4 receptor (DRD4) gene has been frequently studied in relation to attention deficit hyperactivity disorder (ADHD) but little is known about the contribution of single nucleotide polymorphisms (SNPs) of the DRD4 gene to the development and persistence of ADHD. In the present study, we examined the association between two SNPs in DRD4 (rs1800955, rs916455) and adult ADHD persistence in a Chinese sample. Subjects (n=193) were diagnosed with ADHD in childhood and reassessed in young adulthood at an affiliated clinic of Peking University Sixth Hospital. Kaplan-Meier survival analyses and Cox proportional hazard models were used to test the association between ADHD remission and alleles of the two SNPs. DRD4 rs916455 C allele carriers were more likely to have persistent ADHD symptoms in adulthood. No significant association was found between rs1800955 allele and the course of ADHD. These newly detected associations between DRD4 polymorphisms and ADHD prognosis in adulthood may help to predict the persistence of childhood ADHD into adulthood.     

Neuropsychological weaknesses in adult ADHD; cognitive functions as core deficit and roles of them in persistence to adulthood

Prior investigations have shown that individuals with attention deficit hyperactivity disorder (ADHD) have impaired neuropsychological functions. This study had two aims, first to investigate weakened cognitive functions in adult ADHD (aADHD), and second, to investigate difference between persisters (those having persistently ongoing ADHD diagnosis in adulthood), and remitters (those having ADHD diagnosis only in childhood and not in adulthood), in terms of cognitive deficits. We evaluated performance on a comprehensive neuropsychological battery in three groups including 34 persisters, 35 remitters, and 35 healthy control group (absence of childhood and adulthood ADHD diagnosis). Our findings showed that adults with ADHD have inefficient attention, interference control and set-shifting functions, which may be revealed on neuropsychological tests that require greater cognitive demand. Given the finding that interference control deficit exists across the lifespan in people with ADHD, we suggest that interference control-associated functional weakness may be a core deficit for ADHD.

Adult Attention Deficit Disorder and Aggressive Behaviour: An Exploration of Relationships between Brown Attention-Deficit Disorder Scales and the Aggression Questionnaire

Aggressive and violent behaviour is often associated with a diagnosis of attention-deficit hyperactivity disorder (ADHD). This article investigates the relationship between adult attention deficit disorder (ADD) and aggressive cognitions. The Aggression Questionnaire and the Brown Attention-Deficit Disorder Scales were administered to two samples: a “low-risk sample” comprising university students (n = 60), and a “high-risk sample” of prison inmates (n = 117). The prevalence of “probable ADD” was found to be higher in the prison sample (33%), compared with the university sample (20%). There were moderate correlations >r = .5 (p < .01) between total ADHD and Aggression Questionnaire scores in both groups. There were also moderate to strong correlations between subscales of both measures, including cognitive processes such as attention and memory and various forms of aggression, which were particularly apparent in the prison sample. The relationship between ADHD and aggressive behaviour suggests that the treatment of adult ADHD may aid in the management of aggressive behaviour.     

A history of childhood attention‐deficit hyperactivity disorder (ADHD) impacts clinical outcome in adult bipolar patients regardless of current ADHD

Objective: The occurrence of comorbid attention‐deficit hyperactivity disorder (ADHD) might have an impact of the course of the bipolar disorder. Method: Patients with bipolar disorder (n = 159) underwent a comprehensive evaluation with respect to affective symptoms. Independent psychiatrists assessed childhood and current ADHD, and an interview with a parent was undertaken. Results: The prevalence of adult ADHD was 16%. An additional 12% met the criteria for childhood ADHD without meeting criteria for adult ADHD. Both these groups had significantly earlier onset of their first affective episode, more frequent affective episodes (except manic episodes), and more interpersonal violence than the bipolar patients without a history of ADHD. Conclusion: The fact that bipolar patients with a history of childhood ADHD have a different clinical outcome than the pure bipolar group, regardless of whether the ADHD symptoms remained in adulthood or not, suggests that it represent a distinct early‐onset phenotype of bipolar disorder.     

Erfassung des hyperkinetischen Syndroms bei Erwachsenen

The attention-deficit hyperactivity disorder (ADHD) is one of the most common disorders in childhood and adolescence with a prevalence of app. 5%. The importance of ADHD in childhood as a factor of vulnerability for psychiatric disorders in adults is becoming a focus of discussion. It was shown that there is a comorbidity in adults with substance abuse, delinquency and personality disorders. There is a growing evidence that ADHD will persist in a significant number of patients during adulthood. This is the first german study to evaluate this interdependence. We examined 164 adult inpatients and 48 healthy volunteers with the Wender Utah Rating Scale (WURS), a retrospective self-evaluation scale for the diagnosis of ADHD in childhood, and the Eysenck impulsiveness questionnaire I7. It could be shown that the WURS and the I7 are suitable instruments for the evaluation of the ADHD in adults especially concerning the aspects of attention deficits and impulsiveness.

Abstract

Background: No published systematic review has ever assessed the efficacy and safety of reboxetine for treating of patients with attention deficit hyperactivity disorder (ADHD). Aim: This systematic review aimed to review the available evidence regarding the efficacy of reboxetine for treating ADHD. Method: The databases of Pubmed/Medline, Google scholar, SCOPUS and Web of Science were searched using the Keywords: “reboxetine”, “ADHD” and “attention deficit hyperactivity disorder”. The reference lists of the included studies were screened to find any possible other relevant articles. All the non-controlled and controlled clinical trials were included. Results: The current evidence mainly consists of un-controlled studies, such as case series. Only three of 33 studies were controlled clinical trials. They are from single sites and included a sub-sample of patients with ADHD. Conclusion: Non-controlled studies and controlled trials support the promising effect of reboxetine for treating ADHD in a sub-sample of patients that are without co-morbid psychiatric disorder and mental retardation. Reboxetine is tolerated well. However, more controlled trials are needed to reach any firm conclusion.     

Comorbidity of adult attention-deficit hyperactivity disorder and bipolar disorder: prevalence and clinical correlates

The aim of this study was to determine the frequency of adult attention deficit hyperactivity disorder (ADHD) comorbidity with lifetime bipolar disorder, and the influence of this comorbidity on various demographic and clinical variables in patients. Patients (n = 159) with a previous diagnosis of bipolar disorder (79 female, 80 male) were included in this study. All patients were interviewed for the presence of current adult and childhood ADHD diagnosis and other axis I psychiatric disorder comorbidities using the structured clinical interview for DSM-IV (SCID) and the Schedule for Affective Disorders and Schizophrenia for School Age Children—Present and Lifetime Version (K-SADS-PL). The subjects also completed a Wender Utah rating scale (WURS-25) and a Current Symptoms Scale for ADHD symptoms. In particular, patients’ clinical characteristics, the age of onset of bipolar disorder, and the number of episodes were noted. Twenty-six of the 159 bipolar patients (16.3%) were diagnosed with adult ADHD, while another subgroup of patients (n = 17, 10.7%) received a diagnosis of childhood ADHD but did not fulfill criteria for adult ADHD. Both of these two subgroups (patients with adult ADHD, and patients with only childhood ADHD) had an earlier age of onset of the disease and a higher number of previous total affective or depressive episodes than those without any lifetime ADHD comorbidity. However only bipolar patients with adult ADHD comorbidity had higher lifetime comorbidity rates for axis I psychiatric disorders, such as panic disorder and alcohol abuse/dependence, compared to patients without lifetime ADHD. Bipolar patients with comorbid adult ADHD did not differ from bipolar patients with comorbid childhood ADHD in terms of any demographic or clinical variables except for adult ADHD scale scores. In conclusion, ADHD is a common comorbidity in bipolar patients, and it adversely affects the course of the disease and disrupts the social adjustment of the patients. Regular monitoring of ADHD will help to prevent problems and complications that could arise in the course of the disease, particularly in patients with early onset bipolar disorder.     

Attention deficit hyperactivity disorder and the behavior of “Che” Guevara

Attention deficit hyperactivity disorder (ADHD) is a childhood onset neuropsychiatric disorder characterized by inattention, hyperactivity and impulsivity. ADHD is related to several co-morbidities, such as opposition defiant disorder, conduct disorder, mood and anxiety disturbances, as well as tics and Tourette’s syndrome. The objective of this report is to shed an alternative light on the personality of Ernesto “Che” Guevara, discussing whether he might have had ADHD. Several published biographies of Che Guevara were reviewed. Established ADHD criteria (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition), were used as a framework to evaluate Che’s behaviour. In addition, we compared the main features of Che’s reported behaviour to the set of abnormalities leading to the diagnosis of ADHD in adults proposed by Wender and colleagues and known as the UTAH ADHD criteria. Analysis of the most renowned biographies of Ernesto “Che” Guevara suggests that he may have had ADHD.     

Attention deficit hyperactivity disorder in adults

Abstract

Objective. To examine available literature regarding attention deficit hyperactivity disorder (ADHD) in adults. Methods. An electronic literature search of peer-reviewed English language articles using MEDLINE (without time limits) was undertaken. Results. Symptoms of ADHD in adults exert a substantial negative impact on daily life, including work, social life and relationships. Co-morbidities are common, further impairing quality of life. Diagnosis of adult ADHD can be difficult, as current criteria require evidence of symptom onset before the age of 7 years and impact on activities typically undertaken by children. Drug therapy is the first-line treatment for adult ADHD, particularly stimulant medication. However, methylphenidate (MPH) immediate-release tablets require three or more times daily dosing, which can impact on compliance, while demonstrating a loss of symptomatic benefit later in the day. Extended-release preparations of MPH, mixed amphetamine salts and dexamphetamine can provide symptom control for 6–12 h and the non-stimulant atomoxetine has demonstrated benefit in reducing ADHD symptoms. These therapies are generally well tolerated, but may be associated with adverse effects on the cardiovascular system, which need to be further assessed in controlled clinical trials. Psychological therapy may be beneficial in adults who continue to experience clinically significant symptoms while receiving pharmacotherapy. Conclusion. Further research in all areas of adult ADHD is urgently needed.     

A review of fronto-striatal and fronto-cortical brain abnormalities in children and adults with Attention Deficit Hyperactivity Disorder (ADHD) and new evidence for dysfunction in adults with ADHD during motivation and attention

Attention Deficit Hyperactivity Disorder (ADHD) has long been associated with abnormalities in frontal brain regions. In this paper we review the current structural and functional imaging evidence for abnormalities in children and adults with ADHD in fronto-striatal, fronto-parieto-temporal, fronto-cerebellar and fronto-limbic regions and networks. While the imaging studies in children with ADHD are more numerous and consistent, an increasing number of studies suggests that these structural and functional abnormalities in fronto-cortical and fronto-subcortical networks persist into adulthood, despite a relative symptomatic improvement in the adult form of the disorder.We furthermore present new data that support the notion of a persistence of neurofunctional deficits in adults with ADHD during attention and motivation functions. We show that a group of medication-naïve young adults with ADHD behaviours who were followed up 20 years from a childhood ADHD diagnosis show dysfunctions in lateral fronto-striato-parietal regions relative to controls during sustained attention, as well as in ventromedial orbitofrontal regions during reward, suggesting dysfunctions in cognitive-attentional as well as motivational neural networks. The lateral fronto-striatal deficit findings, furthermore, were strikingly similar to those we have previously observed in children with ADHD during the same task, reinforcing the notion of persistence of fronto-striatal dysfunctions in adult ADHD. The ventromedial orbitofrontal deficits, however, were associated with comorbid conduct disorder (CD), highlighting the potential confound of comorbid antisocial conditions on paralimbic brain deficits in ADHD.Our review supported by the new data therefore suggest that both adult and childhood ADHD are associated with brain abnormalities in fronto-cortical and fronto-subcortical systems that mediate the control of cognition and motivation. The brain deficits in ADHD therefore appear to be multi-systemic and to persist throughout the lifespan.     

Familial patterns in disorders of attention and impulse control

Attention deficit hyperactivity disorder (ADHD) persists into adulthood in about 30 to 50% of cases. Symptoms of ADHD in parents might affect effective therapeutic approaches in children. The objective of this study was to investigate (1) the retrospective rate of ADHD in biological parents of children with a diagnosis of ADHD, (2) the relation between retrospective ADHD symptomatology and current attention problems and impulsivity in parents, (3) whether the degree of ADHD severity and comorbidty in ADHD children depends on parental ADHD symptoms. The Wender-Utah-Rating Scale for the retrospective assessment of childhood attention deficit hyperactivity disorder was administered to the biological parents of n = 68 ADHD patients and detected high rates of ADHD in fathers (31%) and mothers (25%) of patients with ADHD. Retrospectively assessed symptoms in parents correlated significantly with current symptoms of attention problems (ADD-Brown scales) and impulsivity (17). In children, the highest degree of ADHD symptoms and comorbidty was found in children with both parents suffering from ADHD in childhood compared to those with only one or none affected parent.     

Childhood attention deficit hyperactivity disorder features in adult mood disorders

A significant overlap between childhood mood disorders and many aspects of attention deficit hyperactivity disorder (ADHD) has been established. High rates of co-occurrence, familial aggregation, and more severe clinical manifestations of the illnesses when they are comorbid suggest that common genetic and environmental factors may contribute to the development of both disorders. Research on the co-occurrence of childhood ADHD and mood disorders in childhood has been conducted. We retrospectively investigated childhood ADHD features in adults with mood disorders. Childhood ADHD features were measured with the Korean version of the Wender Utah Rating Scale (WURS). The sample consisted of 1305 subjects: 108 subjects were diagnosed with bipolar disorder type I, 41 with bipolar disorder type II, 101 with major depressive disorder, and 1055 served as normal controls. We compared total WURS scores as well as scores on 3 factors (impulsivity, inattention, and mood instability and anxiety) among the 4 different diagnostic groups. The 4 groups differed significantly from one another on all scores. The group with bipolar disorder type II obtained the highest total scores on the WURS. The impulsivity and inattention associated with childhood ADHD were more significantly related to bipolar disorder type II than with bipolar disorder type I. The mood instability and anxiety associated with childhood ADHD seem to be significantly related to major depressive disorder in adulthood. In conclusion, multifactorial childhood ADHD features were associated with mood disorders of adulthood.     

Childhood and adult attention deficit hyperactivity disorder symptoms in fibromyalgia: associations with depression,anxiety and disease impact

Abstract

Objective: The first aim of this study was to determine the prevalence of childhood and current attention deficit hyperactivity disorder (ADHD) symptoms in patients with fibromyalgia. The second aim is to assess the role of depression and anxiety on the relationship between childhood and adult ADHD symptoms with disease impact in this population.

Methods: Sixty-four patients with fibromyalgia were compared to matched 58 healthy controls. All participants completed the Wender Utah Rating Scale (WURS), Adult ADHD Self-Report Scale (ASRS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Fibromyalgia Impact Questionnaire (FIQ).

Results: Patients with fibromyalgia had significantly higher mean scores of depression (BDI), anxiety (BAI), childhood ADHD symptoms (WURS) and adult ADHD symptoms (ASRS total, ASRS hyperactivity/impulsivity subscale and ASRS attention deficit subscale) than the control group. Fibromyalgia impact (FIQ) was significantly correlated with depression (BDI; r?=?0.57, p < .001), anxiety (BAI; r?=?0.56, p < .001) and childhood ADHD symptoms (WURS; r?=?0.41, p < .001) in fibromyalgia group. There was no significant correlation between fibromyalgia impact (FIQ) and adult ADHD symptoms (ASRS total or sub-scale scores). Hierarchical multiple regression indicated that childhood ADHD symptoms (WURS), anxiety (BAI) and depression (BDI) predicted fibromyalgia impact. Both anxiety (BAI) and depression (BDI) mediated the relationship between childhood ADHD symptoms (WURS) and fibromyalgia impact (FIQ).

Conclusion: Childhood ADHD symptoms may be a contributory factor to poorer functioning in the patients with fibromyalgia. The relationship was more pronounced in the presence of depression and anxiety symptoms. Evaluation of childhood and adult ADHD symptoms in patients with fibromyalgia is important for recognition and treatment of ADHD comorbidity and also for attenuating the severity of the disease.     

Comparison of QEEG Reference Databases in Basic Signal Analysis and in the Evaluation of Adult ADHD

SUMMARY

Introduction. Despite the relatively widespread investigation of potential quantitative electroencephalographic (QEEG) characteristics of childhood attention deficit hyperactivity disorder (ADHD), relatively little is known about the possible QEEG characteristics of adult ADHD. In addition to general magnitude or power measures, or ratios of these measures, the additional analyses and comparisons provided by QEEG reference databases may prove useful in providing unique markers for adult ADHD.

Method. This investigation reports the findings of evaluations using three QEEG reference databases for a sample of ten adults previously diagnosed with ADHD. The packages used in the current investigation included the NeuroRep QEEG Analysis and Report System, the SKIL Topometric QEEG software package, and the NovaTech EEG EureKa3! QEEG analysis package.

Results. As compared with the respective databases, adults with ADHD appear to demonstrate higher levels of 8–10 Hz activity during both eyes-closed and eyes-open resting baselines. They also appear to demonstrate frontal involvement as evidenced by hypercoherence and hypercomodulation in frontal areas.

Conclusions. Each of the three QEEG reference databases appears to offer unique markers for adult ADHD. However, other apparent differences were found to be attributable to specific analysis packages rather than the clinical group itself. An investigation of basic signal analyses also revealed differences between the three packages. Results of the respective analyses and possible implications are discussed.     

Impaired reward processing in the human prefrontal cortex distinguishes between persistent and remittent attention deficit hyperactivity disorder

Symptoms of attention deficit hyperactivity disorder (ADHD) in children often persist into adulthood and can lead to severe antisocial behavior. However, to‐date it remains unclear whether neuro‐functional abnormalities cause ADHD, which in turn can then provide a marker of persistent ADHD. Using event‐related functional magnetic resonance imaging (fMRI), we measured blood oxygenation level dependent (BOLD) signal changes in subjects during a reversal learning task in which choice of the correct stimulus led to a probabilistically determined ‘monetary’ reward or punishment. Participants were diagnosed with ADHD during their childhood (N = 32) and were paired with age, gender, and education matched healthy controls (N = 32). Reassessment of the ADHD group as adults resulted in a split between either persistent (persisters, N = 17) or remitted ADHDs (remitters, N = 15). All three groups showed significantly decreased activation in the medial prefrontal cortex (PFC) and the left striatum during punished correct responses, however only remitters and controls presented significant psycho‐physiological interaction between these fronto‐striatal reward and outcome valence networks. Comparing persisters to remitters and controls showed significantly inverted responses to punishment (P < 0.05, family‐wise error corrected) in left PFC region. Interestingly, the decreased activation shown after punishment was located in different areas of the PFC for remitters compared with controls, suggesting that remitters might have learned compensation strategies to overcome their ADHD symptoms. Thus, fMRI helps understanding the neuro‐functional basis of ADHD related behavior differences and differentiates between persistent and remittent ADHD.

Diagnostic controversies in adult attention deficit hyperactivity disorder

OBJECTIVE: While it is increasingly recognized that attention deficit hyperactivity disorder (ADHD) persists into adulthood, there is no consensus on diagnostic criteria for adult ADHD. In this article the authors describe and contrast competing approaches for diagnosis of adult ADHD used in clinical and research practice. METHOD: The authors review the Wender Utah criteria, DSM criteria, and laboratory assessment strategies for adult ADHD. Advantages and disadvantages of each approach are described, and recommendations are made as a basis for clinical assessment and future research. RESULTS: Both the Wender Utah criteria and DSM-based approaches identify significantly impaired ADHD adults with neurocognitive, biological, and treatment response patterns similar to pediatric ADHD patients. The Wender Utah criteria established the need for retrospective childhood diagnosis and recognize developmental differences in adult symptom expression. The Wender Utah criteria fail to identify patients with predominantly inattentive symptoms, exclude some patients with significant comorbid psychopathology, and diverge significantly from the DSM conception of ADHD. The DSM criteria have never been validated in adults, do not include developmentally appropriate symptoms and thresholds for adults, and fail to identify some significantly impaired adults who are likely to benefit from treatment. There are insufficient scientific data to justify use of laboratory assessment measures, including neuropsychological tests and brain imaging, in diagnosing adult ADHD. CONCLUSIONS: Adult ADHD remains a clinical diagnosis. Clinicians should be flexible in application of the current ADHD criteria to adults. Additional research is required to validate adult diagnostic criteria.     

Psychopathological,temperamental, and characteristic factors in adults with remaining childhood attention-deficit hyperactivity symptoms

Objectives: To investigate differences in psychopathological, temperamental and characteristic factors between young adults with and without persistent Attention-Deficit Hyperactivity disorder (ADHD) symptoms.

Methods: A total of 429 university students were divided into three groups: persistent adult ADHD (n?=?53), only childhood ADHD (n?=?56) and healthy controls (n?=?320). The Korean Adult ADHD Scale, Korean Wender-Utah Rating Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Barratt Impulsiveness Scale, Korean Young Internet Addiction Scale, and Temperament Character Inventory-Revised (TCI-R; based on Cloninger’s seven factor model of temperament and character) were used to evaluate psychopathological factors.

Results: Participants with persistent adult ADHD symptoms had significantly higher levels of childhood ADHD, depression, anxiety and the Internet addiction symptoms than did the only-childhood ADHD and control groups. The adult ADHD group also had significantly higher tendencies toward novelty seeking, harm avoidance, and self-transcendence, as well as low self-directedness and cooperativeness.

Conclusions: Results suggest that persistent ADHD is associated with several unfavourable psychopathological, temperamental and characteristic factors. Therefore, thorough evaluation of these factors for childhood ADHD could help predict prognoses and provide treatment plans for preventing persistent ADHD into adulthood.     

Comorbid attention-deficit/hyperactivity disorder in adult psychiatric outpatients with depressive or anxiety disorders

Background. There are very few studies reporting on the prevalence and the contribution of not previously diagnosed ADHD in the clinical picture of other psychiatric disorders. The aim of our study is to determine the prevalence and clinical correlates of comorbid attention deficit/hyperactivity disorder (ADHD) in adult psychiatric outpatients with depressive or anxiety disorders. Methods. During a 6-month period, 114 outpatients with depressive or anxiety disorders were evaluated for ADHD diagnosis. Assessment included interviews with both patient and relatives/friends and the use of a daily diary. Moreover, the patients completed the self-report scales Beck Depression Inventory (BDI), Spielberger's Anxiety Inventory (STAI), and the Symptom Checklist-90-R Rating Scale (SCL-90-R). Results. A total of 22 out of 114 patients (19.3%) received an ADHD diagnosis for the first time in their life. Comorbid ADHD compared to non ADHD patients scored significantly higher (p < 0.05) for depression (BDI), state and trait anxiety (STAI) and in the following SCL-90-R factors: Positive Symptoms Distressing Index, Positive Symptoms Index, Somatization, Obsessive Compulsive, Depression, Anxiety, and Hostility. Conclusions. ADHD might go unrecognized among psychiatric outpatients. Patients with depressive or anxiety disorder reporting more severe symptomatology should be carefully screened for possible comorbid adult ADHD.     

Clinical assessment and treatment of attention deficit hyperactivity disorder in adults

Attention deficit hyperactivity disorder (ADHD) is a common childhood disorder that frequently persists into adulthood, with significant levels of inattentive, hyperactive and impulsive behavior. Impairments associated with adult ADHD include distress from the symptoms, impaired ability to function in work and academic settings, and problems sustaining stable relationships. The disorder is commonly associated with volatile moods, antisocial behavior, and drug and alcohol misuse. There is an increased risk of developing comorbid anxiety, depression, personality disorders, and drug and alcohol dependence. Despite the proven effectiveness of drugs such as methylphenidate, dexamphetamine and atomoxetine, few cases of ADHD are recognized and treated in the UK. The reasons for this are unclear, since most psychiatrists working with children and adolescents are aware that ADHD commonly persists into adult life and they also see the disorder affecting parents of children with ADHD. Issues of transition from the care of child to adult psychiatry and the need to refer adult relatives of children with ADHD to suitable psychiatric services are a major concern. Furthermore, many cases of adult ADHD go unrecognized or are seen by mental health teams that are not familiar with the subtleties of the adult presentation. As a result, misdiagnosis and treatment for conditions such as atypical depression, mixed affective disorder, cyclothymia, and borderline and unstable emotional personality disorders is not uncommon. There is therefore a requirement for further training in this area. This review will describe the common clinical presentation and provide guidelines for the diagnosis and treatment of ADHD in adults. Any psychiatrically trained physician using standard psychiatric assessment procedures can perform clinical evaluations for adult ADHD. As with other psychiatric disorders in adulthood, ADHD has its own characteristic onset, course and psychopathology. Symptoms of ADHD are trait-like, being stable characteristics from early childhood, and commonly co-occur with affective instability. Stimulants are the mainstay of treatment and are effective in around 70% of cases. Psychotherapeutic interventions also have an important role. These guidelines will assist psychiatrists and other adult mental health workers in identifying and treating individuals with adult ADHD.     

Adult ADHD: A new disease?

Objectives: Until recently, it was believed that attention deficit and hyperactivity disorder (ADHD) are outgrown by the end of adolescence and the beginning of adulthood. The purpose of this review is to describe the characteristics of the disease in adults, depict comorbidities that accompany it, and expand the scope over methods of diagnosis and treatment of these ages. Methods: A search was conducted in the PubMed/MEDLINE database for relevant key words ‘ADHD’, ‘attention deficit’, ‘hyperactivity’ and ‘adult’. Secondary search parameters were ‘comorbid’, ‘prevalence’, ‘epidemiology’, ‘therapy’ and ‘drug therapy’. Search was limited to ‘English’ and ‘Humans’. Results: Over the years, the persistent nature of the disorder has been clarified, elucidating prevalence rate, gender differences and subtype shifts among adult ADHD population. Nevertheless, even today, there is only limited awareness of the existence of the disorder across one's lifespan, its consequences and the appropriate treatment. Conclusions: Our results emphasise the growing awareness of adult psychosocial impairments due to ADHD symptoms and comorbidities, as well as the need for further collaboration among practitioners and mental health-care professionals to better identify the condition and allow for effective treatment.
