The comorbidity of adult attention-deficit/hyperactivity disorder in bipolar disorder patients (original) (raw)

Bipolar disorder and comorbid attention deficit hyperactivity disorder. A distinct clinical phenotype? Clinical characteristics and temperamental traits 1

World Journal of Biological Psychiatry, 2010

Objectives. It has been suggested that bipolar disorder (BD) with comorbid ADHD represents a distinct clinical phenotype of BD. There are no data regarding potential heterogeneity between BD subjects with a diagnosis of ADHD in childhood whose ADHD remitted in adulthood (cADHD-BD) vs. BD patients with persistent ADHD diagnosis in adulthood (aADHD-BD). This heterogeneity may constitute a confounder in investigations of the nature of the co-occurrence between BD and ADHD. The aim of this paper is to compare BD patients without ADHD, to those with aADHD-BD, and those with cADHD-BD on clinical and temperamental characteristics, hypothesizing that maladaptive temperament will be increased in BD subjects with a stable diagnosis of ADHD in adulthood compared to those whose ADHD remitted. We further hypothesize that maladaptive temperament will be associated with the severity of both illnesses. Methods. A total of 100 outpatients (aged 18 -30 years) with BD in remission were included. The assessment of ADHD was made according to a procedure aimed to reduce potential recall biases. Subjects had to have a parent available and had never been treated with stimulants. Temperamental traits were assessed with the California Child Q-sort (CCQ) and the Early Adolescent Temperament Questionnaire (EATQ). Results. Rate of cooccurrence of ADHD-BD was 18% lifetime and 10% current diagnosis. Patients with ADHD-BD (aADHD-BD ϩ cADHD-BD) reported a signifi cantly earlier onset of mood disorder, higher number of previous mood episodes, and signifi cantly higher impulsivity than BD patients without ADHD. aADHD-BD showed a signifi cantly earlier BD onset, higher number of previous mood episodes, higher impulsivity, decreased Reactive Control and higher Negative Emotionality temperamental scores than cADHD patients. Conclusion. Findings suggest that patients with aADHD-BD present a clinical phenotype distinct from that of patients with BD without ADHD or with a childhood ADHD diagnosis that remitted with the age. This appealing hypothesis of a BD-distinct phenotype that can be detected early due to its associated maladaptive temperamental traits requires further investigation in larger samples, supported by neuropsychological, genetic and imaging data.

Adult ADHD and its comorbidities, with a focus on bipolar disorder

Journal of Affective Disorders, 2010

Attention deficit hyperactivity disorder (ADHD) is a syndrome that most often presents in childhood. However, the condition is also relatively common in adults, with prevalence rates reaching 5% in the general population, with more than half the children affected by ADHD retaining the condition during their adult years. While the disorder in children is most often described as a disorder involving hyperactivity and impulsiveness, ADHD presents with very different characteristics in adulthood, notably with less externalizing symptoms and with a higher rate of psychiatric comorbidities, including major depressive disorder, bipolar disorder (BD), anxiety disorders and substance abuse. This review will focus on the evidence relating to bipolar disorder BD and its potential link with ADHD, looking at epidemiological, familial and neuroimaging studies. The comorbid presentation of people suffering with ADHD and BD (ADHD/BD) is associated with a more severe disease course, more severe mood disorder symptoms, and lower functional scores. Importantly, the co-segregation of these two conditions makes ADHD diagnosis challenging because its symptoms are often mistakenly assumed to be part of BD. As a result, patients with comorbid ADHD/BD are under-diagnosed and under-treated. Optimal diagnosis, understanding and treatment of the comorbid condition are important, as ADHD/BD has been associated with significant functional impairment and suboptimal treatment responses when compared to ADHD or BD populations alone.

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

European Archives of Psychiatry and Clinical Neuroscience, 2008

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.

Comorbidity of Adult Attention Deficit and Hyperactivity Disorder in Bipolar and Unipolar Patients

Noropsikiyatri Arsivi-archives of Neuropsychiatry, 2016

Introduction: The co-occurrence of attention deficit hyperactivity disorder (ADHD) in affective disorder patients is considerably high. The aims of the present study were to search for the frequency and impact of ADHD co-occurrence on the clinical features of affective disorders and to examine the relationship between the dominant affective temperaments and ADHD. Methods: In total, 100 patients with bipolar disorder (BD), 100 patients with major depressive disorder (MDD), and 100 healthy controls (HC) were included. All diagnoses were assigned according to DSM-IV-TR criteria. The Adult Attention Deficit and Hyperactivity Self-Report Scale (ASRS); Wender Utah Rating Scale (WURS); and Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) were applied to all participants. Results: The percentage of BD patients meeting the criteria for a diagnosis of current ADHD was 48% compared with the percentage of MDD patients and HCC subjects, i.e., 25% and 12%, respectively. ADHD was significantly more frequent in bipolar adults than in not only HC but also depressive patients. In the BD group, patients with a comorbid ADHD diagnosis had significantly more suicidal history than those without ADHD. The scores of the temperament traits, namely depressive, cyclothymic, irritable, and anxious, were significantly higher in subjects with ADHD in all groups, including in HC. Conclusion: The most important findings of the present study were the observations that (1) the frequency of ADHD is considerably high among bipolar patients; (2) the frequency of suicide attempts is high in the bipolar patient group with comorbid ADHD; and (3) depressive, cyclothymic, irritable, and anxious temperaments are significantly associated with ADHD comorbidity in bipolar and depressive patients as well as in HC. The high comorbidity and chronic course of ADHD and its possible negative influence on the course of both disorders increase the importance of screening for adult ADHD.

Comorbidity of Adult Attention Deficit and Hyperactivity Disorder in Bipolar Patients: Prevalence, Sociodemographic and Clinical Correlates

Introduction: The aims of this study were to determine the frequency of adult attention deficit and hyperactivity disorder (ADHD) comorbidity in bipolar patients and to investigate the influence of this comorbidity on the clinical characteristics of bipolar disorder (BD). Method: A total of 135 patients with BD type I and II and BD not otherwise specified were included in this study. First, the Adult ADD/ADHD DSM-IV-Based Diagnostic Screening and Rating Scale (ADHD scale) was administered to all patients, and all of the patients were also interviewed for the diagnosis. Patients who were diagnosed as having ADHD comorbidity (n=23) on the basis of DSM-IV and those who were not diagnosed to have ADHD comorbidity (n=32) were compared in terms of sociodemographic and clinical correlates. Results: Twenty-three of 135 patients (17%) were found to have ADHD comorbidity. In the ADHD comorbidity group, the level of education and the number of suicide attempts were higher (p=0.011 and 0.043, respectively). Although not significant, sub-threshold depressive symptoms in interepisodic periods, the lifetime history of antidepressant use and the total number of lifetime depressive episodes tended to be more frequent in bipolar disorder with ADHD comorbidity group than in the control group. Conclu sion: Bipolar disorder has a frequent comorbidity with ADHD, and contrary to expectations, it might be related to the depressive aspect, rather than the manic aspect, of bipolar disorder. Early diagnosis of ADHD comorbidity in bipolar patients might help to prevent serious risk factors. (Archives of Neuropsychiatry 2014; 51: 97-102)

Clinical and Diagnostic Implications of Lifetime Attention-Deficit/Hyperactivity Disorder Comorbidity in Adults with Bipolar Disorder: Data from the First 1000 STEP-BD Participants

Biological Psychiatry, 2005

Background: Systematic studies of children and adolescents with a diagnosis of bipolar disorder show that rates of attention-deficit/ hyperactivity disorder (ADHD) range from 60% to 90%, but the prevalence and implications of ADHD in adults with bipolar disorder are less clear. Methods: The first consecutive 1000 adults with bipolar disorder enrolled in the National Institute of Mental Health's Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) were assessed for lifetime ADHD. The retrospective course of bipolar disorder, current mood state, and prevalence of other comorbid psychiatric diagnoses were compared for the groups with and without lifetime comorbid ADHD. Results: The overall lifetime prevalence of comorbid ADHD in this large cohort of bipolar patients was 9.5% (95% confidence interval 7.6%-11.4%); 14.7% of male patients and 5.8% of female patients with bipolar disorder had lifetime ADHD. Patients with bipolar disorder and ADHD had the onset of their mood disorder approximately 5 years earlier. After adjusting for age of onset, those with ADHD comorbidity had shorter periods of wellness and were more frequently depressed. We found that patients with bipolar disorder comorbid with ADHD had a greater number of other comorbid psychiatric diagnoses compared with those without comorbid ADHD, with substantially higher rates of several anxiety disorders and alcohol and substance abuse and dependence. Conclusions: Lifetime ADHD is a frequent comorbid condition in adults with bipolar disorder, associated with a worse course of bipolar disorder and greater burden of other psychiatric comorbid conditions. Studies are needed that focus on the efficacy and safety of treating ADHD comorbid with bipolar disorder.

Adult attention-deficit hyperactivity disorder in patients with bipolar I disorder in remission: Preliminary study

Psychiatry and Clinical Neurosciences, 2006

Abstract Attention-deficit hyperactivity disorder (ADHD), a syndrome that typically first appears in early childhood, can occur in individuals of all ages. Prospective studies have demonstrated that at least half of children diagnosed as having ADHD continue to suffer the symptoms of this disorder in their adult life with significant impacts on their social status, achievement level and sense of well-being. The purpose of this preliminary study was to determine the rate of ADHD in patients with bipolar disorder (BD) and to examine the effects of comorbid ADHD on several clinical and sociodemographic variables of bipolar patients. Forty-four BD-I patients followed up in psychiatric outpatient clinics in two university hospitals, were assessed for the presence of adult ADHD according to DSM-IV. All patients also completed the Wender Utah Rating Scale for objective evaluation of ADHD. Of 44 patients with BD-I, only seven (15.9%) fulfilled criteria for a diagnosis of adult ADHD. Bipolar disorder-I patients with comorbid ADHD were more likely to be female, and have more affective episodes (especially depressive episodes) than bipolar patients without comorbid ADHD. Age at onset of affective illness was not significantly different between the two groups. In line with results of several previous reports, the present study also showed higher prevalence of ADHD in patients with BD-I than in normal population. A higher number of affective episode in patients with comorbid ADHD may suggest a more severe clinical course of BD in these patients. A larger group of samples is required to clarify the exact association and interaction between these two clinical entities.

j Abstract 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.
