Juvenile mood disorders and office psychopharmacology.

Mood disorders afflict pediatric patients, cause significant impairment, and interfere with normal development. Increasingly, pediatricians are called on to assess and collaborate with mental health practitioners in medicating children and adolescents with mood disorders. Approaching the juvenile with a primary emphasis on clarifying the diagnoses, determining environmental antecedents and sequelae, and investigating suicide risk enables the pediatrician to institute appropriate treatment. Despite limited data from controlled studies, psychotherapy often is used for mild to moderate depression. Pharmacotherapy is indicated in cases unresponsive to psychotherapy and in severe or suicidal cases. First-line pharmacotherapy for depressed adolescents is usually an SRI followed by the atypical or TCA antidepressants. Bipolar disorder typically requires an aggressive medication regimen, including anticonvulsants, lithium, or a combination, as well as environmental modifications. With severe, difficult, or refractory cases, mental health consultation is recommended to clarify diagnoses and to provide psychotherapy and medication input.

Is ADHD a risk factor for psychoactive substance use disorders? Findings from a four-year prospective follow-up study.

OBJECTIVE: To evaluate whether attention-deficit hyperactivity disorder (ADHD) is a risk factor for psychoactive substance use disorders (PSUD), attending to issues of psychiatric comorbidity, family history, and adversity. METHOD: Using assessments from multiple domains, the authors examined 140 ADHD and 120 normal control subjects at baseline and 4 years later. Drug and alcohol abuse and dependence were operationally defined. RESULTS: No differences were detected in the rates of alcohol or drug abuse or dependence or in the rates of abuse of individual substances between the groups; both ADHD and control probands had a 15% rate of PSUD. Conduct and bipolar disorders predicted PSUD, independently of ADHD status. Family history of substance dependence and antisocial disorders was associated with PSUD in controls but less clearly so in ADHD probands. Family history of ADHD was not associated with risk for PSUD. ADHD probands had a significantly shorter time period between the onsets of abuse and dependence compared with controls (1.2 years versus 3 years, p < .01). CONCLUSIONS: Adolescents with and without ADHD had a similar risk for PSUD that was mediated by conduct and bipolar disorder. Since the risk for PSUD has been shown to be elevated in adults with ADHD when compared with controls, a sharp increase in PSUD is to be expected in grown-up ADHD children during the transition from adolescence to adulthood.

Predicting desipramine levels in children and adolescents: a naturalistic clinical study.

OBJECTIVE: To determine the predictability and stability of desipramine (DMI) concentrations in a clinically treated sample of children, estimating the risk of developing potentially toxic DMI levels at a higher dose after a most recent level in a clinically acceptable range. METHOD: Subjects were 90 consecutive psychiatrically referred children and adolescents treated with DMI with at least two assays of serum DMI concentrations (462 pairs). Assay data were analyzed after log transformation and linear regression. RESULTS: Despite wide between-patient variability in serum DMI levels at the same dose, future within-subject DMI blood levels were highly predictable from knowledge of current levels, current dose, and the future dose. When the DMI serum level was 200 to 300 ng/ml, there was a 7.0% risk for subsequent levels at the same dose to exceed 300 ng/mL, but potentially toxic levels above 500 ng/mL were very infrequent (1.7%). CONCLUSIONS: Although the results of this naturalistic clinical study may not generalize to other situations, the results indicate a reasonable stability, predictability, and safety of DMI levels in individual psychiatrically treated children that result from clinically chosen dose changes.

Associations between ADHD and psychoactive substance use disorders. Findings from a longitudinal study of high-risk siblings of ADHD children.

This article investigates the relationship between attention-deficit/hyperactivity disorder (ADHD) and psychoactive substance use disorders (PSUD) in siblings of ADHD and normal-control probands and addresses issues of psychiatric comorbidity and gender. Using DSM-III-R structured diagnostic interviews and blind raters, the authors conducted a 4-year follow-up of siblings. ADHD and male gender predicted higher rates and an earlier onset of PSUD after adjusting for high-risk status, other psychiatric disorders, and age. Risk was particularly high if the siblings had ADHD plus conduct disorder. This study's findings confirms the authors' prior report high-lighting the importance of drug and alcohol prevention and cessation programs aimed at ADHD youth and their siblings, particularly those with comorbid conduct disorder.

A prospective 4-year follow-up study of attention-deficit hyperactivity and related disorders.

BACKGROUND: Previous cross-sectional data showed that children and adolescents with attention-deficit hyperactivity disorder (ADHD) are at increased risk of comorbid conduct, mood, and anxiety disorders as well as impairments in cognitive, social, family, and school functioning. However, longitudinal data were needed to confirm these initial impressions. METHODS: Using DSM-III-R structured diagnostic interviews and raters blinded as to diagnosis, we reexamined psychiatric diagnoses at 1- and 4-year follow-ups in children with ADHD and controls. In addition, subjects were evaluated for cognitive, achievement, social, school and family functioning. RESULTS: Analyses of follow-up findings revealed significant differences between children with ADHD and controls in rates of behavioral, mood, and anxiety disorders, with these disorders increasing markedly from baseline to follow-up assessments. In addition, children with ADHD had significantly more impaired cognitive, family, school, and psychosocial functioning than did controls. Baseline diagnosis of conduct disorder predicted major depression and bipolar disorder at follow-up, and anxiety disorders at baseline predicted anxiety disorders at follow-up. CONCLUSION: These results confirm and extend previous retrospective results indicating that children with ADHD are at high risk of developing a wide range of impairments affecting multiple domains of psychopathology such as cognition, interpersonal, school, and family functioning. These findings provide further support for the value of considering psychiatric comorbidity in both clinical assessment and research protocols involving children with ADHD.

Pharmacotherapy of attention-deficit hyperactivity disorder across the life cycle.

OBJECTIVE: To evaluate the scope of the available therapeutic armamentarium in attention-deficit hyperactivity disorder (ADHD). METHOD: The literature of medication trials in ADHD was systematically reviewed, with attention to issues of psychiatric comorbidity, age, gender, and ethnic background. RESULTS: One hundred fifty-five controlled studies of 5,768 children, adolescents, and adults have documented the efficacy of stimulants in an estimated 70% of subjects. The literature clearly documents that stimulants not only improve abnormal behaviors of ADHD, but also self-esteem, cognition, and social and family function. However, response varied in different age groups and with certain comorbid conditions. In addition, there is an impressive body of literature documenting the efficacy of tricyclic antidepressants on ADHD in more than 1,000 subjects. Studies of alternative antidepressants, antipsychotics, antihypertensives, and other compounds were also reviewed. CONCLUSIONS: The available literature indicates the important role of psychopharmacological agents in the reduction of the core symptoms of ADHD and associated impairments. More research is needed on alternative pharmacological treatments and to further evaluate established therapeutics beyond school-age Caucasian boys. In addition, more research is needed on the efficacy of treatment for comorbid ADHD, use of combined medications, and the combination of medication and psychosocial treatment.

A double-blind, crossover comparison of methylphenidate and placebo in adults with childhood-onset attention-deficit hyperactivity disorder.

BACKGROUND: There are few controlled studies of methylphenidate hydrochloride in adults with attention-deficit hyperactivity disorder (ADHD), and their results have been equivocal. The discrepancies among these studies may be related to low doses, diagnostic uncertainties, and lack of attention to comorbid disorders. METHODS: We conducted a randomized, 7-week, placebo-controlled, crossover study of methylphenidate in 23 adult patients with DSM-III-R ADHD using standardized instruments for diagnosis, separate assessments of ADHD and depressive and anxiety symptoms, and a robust daily dose of methylphenidate hydrochloride, 1.0 mg/kg per day. RESULTS: We found a marked therapeutic response for methylphenidate treatment of ADHD symptoms that exceeded the placebo response (78% vs 4%, P < .0001). Response to methylphenidate was independent of gender, psychiatric comorbidity with anxiety or moderate depression, or family history of psychiatric disorders. CONCLUSION: Robust doses of methylphenidate are effective in the treatment of adult ADHD.

The relationship between tic disorders and Tourette's syndrome revisited.

OBJECTIVE: The relationship between Tourette's syndrome (TS) and chronic tic disorder is of great clinical and scientific importance because of uncertainties in both prognosis and pharmacotherapeutic strategies. One approach to evaluating the relationship between TS and chronic tics is to examine whether they share similar neuropsychological and psychiatric correlates. METHOD: Children with TS (n = 32) and children with chronic tics (n = 39) were ascertained from an unselected sample of the children referred for psychopharmacological treatment and examined using standardized diagnostic assessments and testing procedures. RESULTS: Children with TS and those with chronic tics were similar to each other and different from controls in clinical correlates that included psychiatric comorbidity, as well as school, neuropsychological, and psychosocial impairments. Patients with TS also had higher rates of obsessive-compulsive disorder, oppositional defiant disorder, and simple phobia than did patients with chronic tic disorder. CONCLUSIONS: These findings indicate that TS and chronic tic disorder are part of the same disease entity, with TS being a more severe form of tic disorder.

ADHD and thyroid abnormalities: a research note.

Contradictory findings have been reported on associations between ADHD and thyroid abnormalities including the syndrome of generalized resistance to thyroid hormone. We systematically reviewed thyroid function in a large group of children and adolescents with ADHD (N = 132). We failed to find evidence of generalized resistance to thyroid hormone. Although mild laboratory abnormalities in thyroid function were observed in a minority of ADHD subjects, they were not different than rates reported in the literature for normal children.

Psychoactive substance use disorders in adults with attention deficit hyperactivity disorder (ADHD): effects of ADHD and psychiatric comorbidity.

OBJECTIVE: The authors evaluated the association between attention deficit hyperactivity disorder (ADHD) and psychoactive substance use disorders in adults with ADHD, attending to comorbidity with mood, anxiety, and antisocial disorders. It was hypothesized that psychiatric comorbidity would be a risk factor for psychoactive substance use disorders. METHOD: Findings for 120 referred adults with a clinical diagnosis of childhood-onset ADHD were compared with those for non-ADHD adult comparison subjects (N = 268). All childhood and adult diagnoses were obtained by structured psychiatric interviews for DSM-III-R. RESULTS: There was a significantly higher lifetime risk for psychoactive substance use disorders in the ADHD adults than in the comparison subjects (52% versus 27%). Although the two groups did not differ in the rate of alcohol use disorders, the ADHD adults had significantly higher rates of drug and drug plus alcohol use disorders than the comparison subjects. ADHD significantly increased the risk for substance use disorders independently of psychiatric comorbidity. Antisocial disorders significantly increased the risk for substance use disorders independently of ADHD status. Mood and anxiety disorders increased the risk for substance use disorders in both the ADHD and comparison subjects, but more demonstrably in the comparison subjects. CONCLUSIONS: Although psychiatric comorbidity increased the risk for psychoactive substance use disorders in adults with ADHD, by itself ADHD was a significant risk factor for substance use disorders. More information is needed to further delineate risk and protective factors mediating the development of substance use disorders in persons with ADHD.

High risk for attention deficit hyperactivity disorder among children of parents with childhood onset of the disorder: a pilot study.

OBJECTIVE: Although well-documented in clinical and epidemiological studies of attention deficit hyperactivity disorder (ADHD) in children, the familial nature of the adult syndrome has not been well investigated. One approach to evaluate the familial nature of adult ADHD is through a high-risk design aimed at estimating the risk for the disorder in children of parents with child-hood-onset ADHD. METHOD: Children at risk for ADHD were ascertained from the study group of 84 referred adults with clinical diagnoses of childhood onset of the disorder, confirmed by structured interviews. Diagnostic information on the disorder was derived from the ADHD module of the Schedule for Affective Disorders and Schizophrenia for School Age Children--Epidemiologic Version, supplemented with information regarding treatment for ADHD for the affected child and school history including repeated grades, placement in special classes, and tutoring. RESULTS: Of the 84 children at risk, 48 (57%) met criteria for ADHD. The rate of the disorder in children of adults with the disorder was significantly higher than the previously reported rate of ADHD among siblings of children with the disorder. Of the 48 ADHD children of parents with the disorder, 36 (75%) were treated for it. The rates of school failure were almost identical to those previously reported in a group of referred children and adolescents with ADHD. CONCLUSIONS: These results support the validity of the adult diagnosis of ADHD and suggest that the adult form of this disorder may have stronger familial etiological risk factors than its pediatric form. If these results are confirmed, families selected through adult probands with ADHD might be especially useful for testing genetic hypotheses about the disorder.

Gender differences in a sample of adults with attention deficit hyperactivity disorder.

Although originally conceptualized as a childhood disorder, attention deficit hyperactivity disorder (ADHD) may also be an adult disorder. However, despite increasing media attention to adult ADHD, its validity has only recently been studied in a systematic fashion. The overrepresentation of females in adult samples in comparison to pediatric samples of ADHD raises additional questions about the validity of this disorder in adults. The goal of this article is to explore whether ADHD is a valid clinical entity in female subjects and whether it is expressed differently in male and female adults. To this end, we examined the clinical, cognitive, and functional characteristics of 128 referred adult ADHD cases of both sexes. Each subject had a clinical diagnosis of childhood-onset ADHD confirmed by structured interview. The male and female ADHD adults were similar to one another but more disturbed and impaired than non-ADHD adult control subjects. Compared with normal control females, ADHD women had higher rates of major depression, anxiety disorders, and conduct disorder; and more evidence of school failure and cognitive impairment. The consistency of these findings in both genders further supports the validity of the diagnosis of ADHD in adults. Our results stress the viability and importance of identification of female subjects with ADHD. The underidentification and undertreatment of females with ADHD may have substantial mental health and educational implications, suggesting that research is needed to develop a better understanding of clinical indicators of ADHD in females.

Nortriptyline treatment of children with attention-deficit hyperactivity disorder and tic disorder or Tourette's syndrome.

Although as many as 50% of patients with Tourette's syndrome (TS) also meet diagnostic criteria for Attention-deficit Hyperactivity Disorder (ADHD), until recently little attention has been paid to ADHD symptoms in the assessment of therapeutic outcome of TS or patients with chronic motor tics (CMT). Because antipsychotics are of limited value in controlling the symptoms of ADHD and stimulants can exacerbate tics, alternative treatments for patients with chronic tic disorder (CTD) (TS or CMT) plus ADHD (CTD+ADHD) patients are direly needed. We examined the efficacy of the tricyclic antidepressant nortriptyline in the treatment of pediatric patients with CTD+ADHD ascertained from systematic chart reviews of all subjects with this diagnosis treated with nortriptyline. Of the 12 identified patients, 67% had significant improvement in CTD symptomatology and 92% significantly improved ADHD symptoms without major adverse effects over an average follow-up period of 19 months. Although the conclusions from this retrospective report can be only seen as preliminary until replicated in a controlled investigation, the magnitude and persistence of the response is encouraging and suggest a therapeutic role for nortriptyline in the treatment of CTD+ADHD patients.

Bupropion exacerbates tics in children with attention-deficit hyperactivity disorder and Tourette's syndrome.

Concerns have been raised regarding the development of tics in some children with attention-deficit hyperactivity disorder (ADHD) receiving stimulants. Because in many patients with Tourette's syndrome (TS) the ADHD symptoms are the major source of disability, alternative nonstimulant treatments are needed. Initial reports on bupropion have suggested that it may be an effective alternative in children and adults with ADHD. The value of bupropion as an alternative treatment for patients with comorbid TS and ADHD is determined by the question of association with exacerbation of tics. The purpose of this study was to examine an apparent association with exacerbation of tics in patients with comorbid TS and ADHD. A careful retrospective analysis was conducted of clinic cases of patients who all had comorbid TS and ADHD treated with bupropion. We present four cases of children with ADHD and comorbid TS treated with bupropion in whom tics were exacerbated by this medicine. This series suggests that bupropion may not be an appropriate alternative to stimulants in the treatment of ADHD in TS.

Comparison of clonidine response in the treatment of attention-deficit hyperactivity disorder with and without comorbid tic disorders.

OBJECTIVE: Clonidine has been suggested as an alternative pharmacotherapy for patients with attention-deficit hyperactivity disorder (ADHD) and comorbid tic disorders. To examine the efficacy of clonidine in this population of children, the use of clonidine in the treatment of children with ADHD with and without comorbid tic disorders was examined in a retrospective chart review of 54 children over a 4-year period. METHOD: Treatment was administered openly to these patients in a Pediatric Psychopharmacology Clinic, and response was assessed using clinical global improvement measures. RESULTS: Clonidine treatment resulted in improvement in both the ADHD (39/54; 72%) and tic symptoms (18/24; 75%) groups. The findings suggested that the children with ADHD with comorbid tic disorders (23/24; 96%) have a more frequent positive behavioral response to clonidine than children with ADHD without comorbid tic disorders (16/30; 53%). CONCLUSIONS: This report provides further support of a role for clonidine in the treatment of children with ADHD, particularly for those with comorbid tic disorders.

Desipramine treatment of children with attention-deficit hyperactivity disorder and tic disorder or Tourette's syndrome.

OBJECTIVE: As many as 50% of patients with Tourette's syndrome (TS) also meet diagnostic criteria for attention-deficit hyperactivity disorder (ADHD). Since antipsychotics are of limited value in controlling the symptoms of ADHD and stimulants can exacerbate tics, alternative treatments are directly needed. The purpose of this study was the examination of the efficacy of desipramine (DMI) in the treatment of pediatric patients with chronic tic disorder (CTD; TS or chronic motor tics) + attention-deficit hyperactivity disorder (ADHD). METHOD: All pediatric patients with the diagnosis of CTD that were treated with DMI were ascertained from retrospective systematic chart reviews of a psychopharmacology clinic and a neurology service specialized in movement disorders. RESULTS: Of the 33 identified patients, 30 had comorbid CTD + ADHD and three had CTD alone. In all, 82% had significant improvement in CTD symptomatology and 80% significantly improved ADHD symptoms without major adverse effects over an average follow-up period of 16 months. CONCLUSIONS: Although the conclusions from this retrospective report can be seen as preliminary only until replicated in a controlled investigation, the magnitude and persistence of the response is encouraging and suggest a therapeutic role for DMI in the treatment of CTD + ADHD patients.

Patterns of psychiatric comorbidity, cognition, and psychosocial functioning in adults with attention deficit hyperactivity disorder.

OBJECTIVE: Although attention deficit hyperactivity disorder is a common disorder of childhood, its status as a disorder in adults is not clear. The authors reasoned that if the adult diagnosis of the disorder is a valid clinical entity, it should be similar to the childhood disorder with regard to patterns of psychiatric and cognitive findings. METHODS: Eighty-four adults with a clinical diagnosis of childhood-onset attention deficit hyperactivity disorder confirmed by structured interview who were referred for treatment were studied. Findings were compared with those from a preexisting study group of referred children with attention deficit hyperactivity disorder, nonreferred adult relatives of those children who also had attention deficit hyperactivity disorder, and adults without the disorder who were relatives of normal children. Subjects were evaluated with a comprehensive battery of psychiatric, cognitive, and psychosocial assessments. RESULTS: The referred and nonreferred adults with attention deficit hyperactivity disorder were similar to one another but more disturbed and impaired than the comparison subjects without the disorder. The pattern of psychopathology, cognition, and functioning among the adults with attention deficit hyperactivity disorder approximated the findings for children with the disorder. CONCLUSIONS: These results show that referred and nonreferred adults with attention deficit hyperactivity disorder have a pattern of demographic, psychosocial, psychiatric, and cognitive features that mirrors well-documented findings among children with the disorder. These findings further support the validity of the diagnosis for adults.
