Comorbidity of parental anxiety disorders as risk for childhood-onset anxiety in inhibited children.

OBJECTIVE: Previous work suggested that children of parents with panic disorder and agoraphobia were likely to be classified as behaviorally inhibited and that behaviorally inhibited children were likely to develop anxiety disorders. However, the factors determining which inhibited children were at risk for childhood onset of anxiety disorders remained unknown. The authors of this study hypothesized that greater anxiety loading in parents would increase the risk for anxiety disorders in children with behavioral inhibition. METHOD: Using DSM-III structured interviews, the authors examined patterns of aggregation of anxiety disorders in parents of two existing cohorts of children, one cross-sectional and clinically derived (31 children, 60 parents) and the other epidemiologically derived and longitudinal (40 children, 75 parents). Within each cohort, parents were stratified into three groups based on the presence (behavioral inhibition and anxiety) or absence (behavioral inhibition only, no behavioral inhibition and no anxiety) of behavioral inhibition and two or more anxiety disorders in their child. RESULTS: Parents of children with behavioral inhibition and anxiety, from both the clinical and nonclinical cohorts, had significantly higher rates of two or more anxiety disorders than did parents of children with behavioral inhibition only and parents of children with no behavioral inhibition and no anxiety. CONCLUSIONS: These results indicate that the presence of parental loading for anxiety disorders may help to identify the subgroup of inhibited children at very high risk for developing childhood-onset anxiety disorders.

The stimulants.

Stimulants are the most commonly prescribed psychotropic medications in child psychiatry, used generally for the treatment of attention deficit hyperactivity disorder (ADHD). In this article, the authors summarize the literature on the prevalence of use, neurobiology, and pharmacology of stimulants. Likewise, recent studies on the use of stimulants are reviewed, such as their use in specific ADHD populations including those with conduct disorder, girls, preschoolers, adolescents, and adults. Clinical guidelines for the management of children and adolescents receiving stimulants are offered, and treatment strategies are delineated for ADHD subjects with comorbidity and medication-induced adverse effects.

Evidence of familial association between attention deficit disorder and major affective disorders.

With the use of family study methods and assessments by "blinded" raters, we tested hypotheses about patterns of familial association between DSM-III attention deficit disorder (ADD) and affective disorders (AFFs) among first-degree relatives of clinically referred children and adolescents with ADD (73 probands, 264 relatives) and normal controls (26 probands, 92 relatives). Among the 73 ADD probands, 24 (33%) met criteria for AFFs (major depression, n = 15 [21%]; bipolar disorder, n = 8 [11%]; and dysthymia, n = 1 [1%]). After stratification of the ADD sample into those with AFFs (ADD + AFF) and those without AFF (ADD), familial risk analyses revealed the following: (1) the relatives of each ADD proband subgroup were at significantly greater risk for ADD than were relatives of normal controls; (2) the age-corrected morbidity risk for ADD was not significantly different between relatives of ADD and ADD + AFF (27% vs 22%); however, these two risks were significantly greater than the risk to relatives of normal controls (5%); (3) the risk for any AFF (bipolar disorder, major depressive disorder, or dysthymia) was not significantly different between relatives of ADD probands and ADD + AFF probands (28% and 25%), but these two risks were significantly greater than the risk to relatives of normal controls (4%); (4) ADD and AFFs did not cosegregate within families; and (5) there was no evidence for nonrandom mating. These findings are consistent with the hypothesis that ADD and AFFs may share common familial vulnerabilities.

Further evidence of an association between behavioral inhibition and anxiety disorders: results from a family study of children from a non-clinical sample.

Behavioral inhibition to the unfamiliar, identifiable in early childhood and reflecting the tendency to exhibit withdrawal and excessive autonomic arousal to challenge or novelty, has been found to be prevalent in young offspring of parents with panic disorder and agoraphobia and associated with risk for anxiety disorders in these children. Using family study methodology, we now examine psychopathology in first degree relatives of children from a non-clinical longitudinal cohort identified at 21 months of age as inhibited (N = 22) or uninhibited (N = 19) and followed through the age of seven years for a study of preservation of temperamental characteristics in normal children. These assessments were compared with evaluations of the first degree relatives of 20 normal comparison children. Psychiatric assessments of parents (N = 110) and siblings (N = 72) were based on structured interviews conducted blindly to the temperamental classification of the index child. Parents of inhibited children, compared with parents of uninhibited and normal controls, had significantly higher risks for multiple (greater than or equal to 2) anxiety disorders, continuing anxiety disorders (both a childhood and adulthood anxiety disorder in the same parent), social phobia, and childhood avoidant and overanxious disorders. These findings provide additional support for the hypothesis linking behavioral inhibition with risk for anxiety disorder.

A high risk study of young children of parents with panic disorder and agoraphobia with and without comorbid major depression.

Using family study methodology and psychiatric assessments by blind raters, this study tested hypotheses about patterns of familial association between anxiety and depressive disorders among high risk children of clinically referred parents. The study design contrasted five groups of children defined by the presence or absence in a parent of (1) panic disorder and agoraphobia (PDAG) without comorbid major depressive disorder (MDD) (n = 14); (2) comorbid PDAG plus MDD (PDAG + MDD) (n = 25); (3) MDD without comorbid PDAG (n = 12); (4) other psychiatric disorders (n = 23); and (5) normal comparisons (n = 47). While the PDAG and PDAG + MDD groups had similarly elevated rates of anxiety disorders and MDD, offspring of MDD parents had an elevated rate of MDD but not of anxiety disorders. Among children of parents with PDAG + MDD, the presence of an anxiety disorder did not significantly increase the risk for MDD in the same child. Thus, anxiety and MDD did not cosegregate among children of PDAG parents. These findings indicate that parental PDAG, either alone or comorbidly with MDD, increases the risk for both anxiety and depressive disorders in offspring. In the absence of PDAG, however, parental MDD does not appear to place children at risk for anxiety disorders. These findings are most consistent with the hypothesis that PDAG and PDAG + MDD share common familial etiologic factors while MDD alone is an independent disorder. More studies are needed to confirm these preliminary findings as well as to identify mediating factors that influence the transition from childhood to adult anxiety disorders.

Separation of DSM-III attention deficit disorder and conduct disorder: evidence from a family-genetic study of American child psychiatric patients.

Using family study methodology and assessments by blind raters, this study tested hypotheses about patterns of familial association between DSM-III attention deficit disorder (ADD) and antisocial disorders (childhood conduct (CD) and oppositional disorder (OPD) and adult antisocial personality disorder) among 457 first-degree relatives of clinically referred children and adolescents with ADD (73 probands, 264 relatives), psychiatric (26 probands, 101 relatives) and normal controls (26 probands, 92 relatives). Among the 73 ADD probands, 33 (45%) met criteria for OPD, 24 (33%) met criteria for CD, and 16 (22%) had no antisocial diagnosis. After stratifying the ADD sample into those with CD (ADD + CD), those with OPD (ADD + OPD) and those with neither (ADD) familial risk analysis revealed the following: (1) relatives of each ADD proband subgroup were at significantly greater risk for ADD than relatives of both psychiatric and normal controls: (2) the morbidity risk for ADD was highest among relatives of ADD + CD probands (38%), moderate among relatives of ADD + OPD (17%) and ADD probands (24%) and lowest among relatives of psychiatric and normal controls (5% for both); (3) the risk for any antisocial disorder was highest among relatives of ADD + CD (34%) and ADD + OPD (24%) which were significantly greater than the risk to relatives of ADD probands (11%), psychiatric (7%) and normal controls (4%); and (4) both ADD and antisocial disorders occurred in the same relatives more often than expected by chance alone. Although these findings suggest that ADD with and without antisocial disorders may be aetiologically distinct disorders, they are also consistent with a multifactorial hypothesis in which ADD, ADD + OPD and ADD + CD fall along a continuum of increasing levels of familial aetiological factors and, correspondingly, severity of illness.

A family-genetic study of girls with DSM-III attention deficit disorder.

OBJECTIVE: The authors evaluated family-genetic risk factors in girls with attention deficit disorder and compared these results to findings in the authors' previous study of boys with attention deficit disorder. METHOD: Twenty-one girls with attention deficit disorder and 20 normal comparison girls were consecutively ascertained from a pool of existing and new referrals from a pediatric psychopharmacology unit and a medical pediatric unit of the same urban hospital. First-degree relatives of the attention deficit disordered girls (N = 69) and of the normal girls (N = 71) were also assessed. Both groups of girls and their relatives were evaluated on the basis of structured diagnostic interviews conducted by raters who were blind to the clinical status of the probands. RESULTS: The relatives of the girls with attention deficit disorder had higher risks for attention deficit disorder, antisocial disorders, major depression, and anxiety disorders. The higher risk for attention deficit disorder could not be accounted for by gender or generation of relative, age of proband, social class, or family intactness. These findings are highly consistent with the findings in the authors' previous study of boys with attention deficit disorder, which was conducted with identical methods. CONCLUSIONS: This study provides further support for the validity of the diagnosis of attention deficit disorder in girls and suggests that the genders share a common biological substrate.

Familial association between attention deficit disorder and anxiety disorders.

BACKGROUND AND METHOD: This study tested hypotheses about patterns of familial association between attention deficit disorder (ADD) and anxiety disorders among 356 first-degree relatives of 73 clinically referred children with ADD and 26 normal comparison children. Through structured diagnostic interviews with trained raters, relatives were assessed for adult and childhood psychopathology. After stratifying the sample of ADD probands into those with anxiety disorders and those without, the authors examined patterns of aggregation of ADD and anxiety disorders in the relatives of these probands as well as in the relatives of the normal comparison subjects. RESULTS: Familial risk analyses revealed that 1) familial risk for anxiety disorders was higher among all ADD probands than among the normal subjects; 2) familial risk for ADD was similar in the relatives of the ADD probands and of the probands with ADD and anxiety disorder; 3) the relatives of the ADD probands with and without anxiety disorders were at greater risk for ADD than the relatives of the normal subjects; 4) the risk for anxiety disorders was two times higher in the relatives of the probands who had ADD with anxiety disorder than in those of the ADD probands without anxiety disorders; and 5) there was a tendency for ADD probands' relatives who themselves had ADD to have a higher risk for anxiety disorders than ADD probands' relatives who did not have ADD (cosegregation). CONCLUSIONS: The results were most consistent with the hypotheses indicating that ADD and anxiety disorders segregate independently in families.

Comorbidity of attention deficit hyperactivity disorder with conduct, depressive, anxiety, and other disorders.

OBJECTIVE: Attention deficit hyperactivity disorder is a heterogeneous disorder of unknown etiology. Little is known about the comorbidity of this disorder with disorders other than conduct. Therefore, the authors made a systematic search of the psychiatric and psychological literature for empirical studies dealing with the comorbidity of attention deficit hyperactivity disorder with other disorders. DATA COLLECTION: The search terms included hyperactivity, hyperkinesis, attention deficit disorder, and attention deficit hyperactivity disorder, cross-referenced with antisocial disorder (aggression, conduct disorder, antisocial disorder), depression (depression, mania, depressive disorder, bipolar), anxiety (anxiety disorder, anxiety), learning problems (learning, learning disability, academic achievement), substance abuse (alcoholism, drug abuse), mental retardation, and Tourette's disorder. FINDINGS: The literature supports considerable comorbidity of attention deficit hyperactivity disorder with conduct disorder, oppositional defiant disorder, mood disorders, anxiety disorders, learning disabilities, and other disorders, such as mental retardation, Tourette's syndrome, and borderline personality disorder. CONCLUSIONS: Subgroups of children with attention deficit hyperactivity disorder might be delineated on the basis of the disorder's comorbidity with other disorders. These subgroups may have differing risk factors, clinical courses, and pharmacological responses. Thus, their proper identification may lead to refinements in preventive and treatment strategies. Investigation of these issues should help to clarify the etiology, course, and outcome of attention deficit hyperactivity disorder.

Screening for dysfunction in the children of outpatients at a psychopharmacology clinic.

OBJECTIVE: The goals of this study were 1) to determine whether the use of the Pediatric Symptom Checklist in an adult-oriented psychiatric practice was feasible, 2) to determine if scores indicative of dysfunction on the Pediatric Symptom Checklist were associated with parental or background factors, 3) to determine whether children flagged by their scores on the Pediatric Symptom Checklist were receiving psychiatric services, and 4) to compare the psychosocial dysfunction in this group of children with that found in children screened as part of routine pediatric visits. METHOD: Adult outpatients in a hospital's clinical psychopharmacology unit were asked to complete the Pediatric Symptom Checklist regarding their children. These patients were the parents of 100 school-aged children. Factors such as the parents' diagnoses and demographic variables were also examined. RESULTS: The Pediatric Symptom Checklist was readily accepted by parents and fit easily into the routine of general psychiatric practice. Significantly more of the children of these outpatients than of children in comparable pediatric offices had scores indicative of psychiatric dysfunction (scores above the cutoff). Children of parents who were single, of low socioeconomic status, or with a diagnosis of personality (especially borderline) or mood disorder were more likely to have scores above the cutoff. More than a third of the children who had scores above the cutoff on the Pediatric Symptom Checklist were not currently receiving psychiatric services. CONCLUSIONS: The Pediatric Symptom Checklist provided a rapid and simple method for general psychiatrists to identify psychosocial dysfunction in their patients' children.

Behavioral inhibition in children: a possible precursor to panic disorder or social phobia.

A biological-environmental interaction currently provides the best explanation of an anxiety disorder's evolution. In this sense, anxiety disorders are like other medical disorders for which a person may have a predisposition. Our knowledge of the evolution of anxiety disorders would be enhanced by the ability to identify those persons predisposed to anxiety and to identify such "proneness" before an anxiety disorder emerges in adulthood. We discuss the developmental aspects of panic disorder and social phobia, in particular findings suggesting that behavioral inhibition in children may be a precursor to phobic disorders in adults. Only longitudinal studies will resolve whether childhood response patterns are specifically linked to the risk of developing anxiety disorders or other psychopathology across the life cycle. In the interim, we suggest some guidelines for parents and clinicians to meet the unique needs of the inhibited child.

Comorbidity in the interpretation of dexamethasone suppression test results in children: a review and report.

The dexamethasone suppression test (DST) was administered as part of the initial clinical assessment to 83 children and adolescents who were consecutively referred for outpatient evaluation. All diagnoses were made clinically by a child psychiatrist according to DSM-III criteria. A weight-corrected dose of dexamethasone of 17 micrograms/kg was used. DSM-III diagnoses were made independent of DST results. Patients were stratified into four main diagnostic groups: major depressive disorder (MDD) (N = 27); attention deficit disorder with hyperactivity (ADDH) (N = 22); major depressive disorder plus attention deficit disorder with hyperactivity (MDD + ADDH) (N = 29); and psychiatric controls (PC) (N = 5). Rates of dexamethasone nonsuppression were found to be similarly elevated in children with MDD (29.6%), ADDH (22.7%), and MDD + ADDH (37.9%). All 5 psychiatric control patients had a normal postdexamethasone suppression (0%). A similar pattern of results emerged in a reexamination of the literature on available studies of DST in juveniles which revealed that children with major affective disorders, attention deficit disorder (ADDH), and anxiety disorders had comparable DST results that were significantly higher than the 5.6% rate found in normal controls. These findings provide further support for similarities in DST results between ADDH and MDD in outpatients. Although these results suggest a lack of specificity of the DST as a laboratory aid for the diagnosis of juvenile affective disorders, they are also consistent with findings indicating that the DST may be an index of clinical severity and other findings suggesting a possible association between ADDH and MDD. Despite its limitations, the DST may provide potentially useful clinical and research information regarding the pathophysiology of psychiatric disorders and in alerting clinicians to the presence of serious psychiatric disorders. The findings also stress the relevance of assessing comorbidity in interpreting DST results.

Psychiatric correlates of behavioral inhibition in young children of parents with and without psychiatric disorders.

Behavioral inhibition is a laboratory-based temperamental category by the tendency to constrict behavior in unfamiliar situations and assumed to reflect low thresholds of limbic arousal. We previously found behavioral inhibition prevalent in the offspring of parents with panic disorder and agoraphobia. In this report, we examined the psychiatric correlates of behavioral inhibition by evaluating the sample of offspring of parents with panic disorder and agoraphobia, previously dichotomized as inhibited and not inhibited, and an existing epidemiologically derived sample of children, followed by Kagan and colleagues and originally identified at 21 months of age as inhibited or uninhibited. A third group of healthy children was added for comparison. Our findings indicate that inhibited children had increased risk for multiple anxiety, overanxious, and phobic disorders. It is suggested that behavioral inhibition may be associated with risk for anxiety disorders in children.

Family-genetic and psychosocial risk factors in DSM-III attention deficit disorder.

Using family study methodology and assessments made by blind raters, this study evaluated family-genetic and psychosocial risk factors for DSM-III attention deficit disorder (ADD) among the 457 first-degree relatives of clinically referred children and adolescents with ADD (N = 73), compared with psychiatric (N = 26) and normal controls (N = 26). Relatives of ADD probands had a higher morbidity risk for ADD (25.1% versus 5.3% versus 4.6%, ps less than 0.00001), antisocial disorders (25.3% versus 6.9% versus 4.2%, ps less than 0.00001), and mood disorders (27.1% versus 13.9%, p = 0.038 and 27.1% versus 3.6%, p = 0.00001) than did relatives of psychiatric and normal controls. The increased risk for ADD could not be accounted for by gender or generation of relative, the age of proband, social class, or the intactness of the family. These results confirm and extend previous findings indicating important family-genetic risk factors in ADD.

Parent-based diagnosis of attention deficit disorder predicts a diagnosis based on teacher report.

The literature evaluating agreement between parent and teacher reports on symptoms of attention deficit disorder (ADD) has repeatedly shown only modest correlations between these two sources of information. A more relevant statistic to this clinical issue, however, is the positive predictive power, the conditional probability that diagnostic criteria will be met by teacher's report if that diagnosis has been made based on parental report. In a population of 43 children (ages 4 to 17) satisfying clinical criteria for DSM-III ADD, parents and teachers independently completed them module on ADD derived from the Diagnostic Interview for Children and Adolescents. Although correlations for individual symptoms were low to moderate, there was a 90% probability that the teacher report would result in a positive diagnosis given a positive parent diagnosis, indicating a very high probability that, in clinically referred children, a clinical diagnosis of ADD based on parent report will be corroborated by a teacher report.

The diagnosis and treatment of adolescent anxiety disorders.

In adolescents, anxiety disorders may be manifested as juvenile anxiety syndromes, adult anxiety syndromes, or an adjustment disorder with anxious mood. In addition, depressive illnesses and attention-deficit hyperactivity disorder often exist comorbidly with the primary anxiety disorder. The treatment of anxiety in adolescents should be multimodal, including psychotherapeutic and psychosocial interventions along with pharmacotherapy. Tricyclic antidepressants and monoamine oxidase inhibitors have been successful in most anxiety disorders, although both classes of drug are associated with significant adverse effects and require careful monitoring. Benzodiazepines are effective in juvenile anxiety disorders. Clonazepam's long duration of action and relatively benign side-effects profile make it an attractive agent in adolescent populations.

Fluoxetine-induced sexual dysfunction.

Of the first 60 patients treated at our clinic with the antidepressant fluoxetine, 5 (8.3%) developed treatment-emergent sexual dysfunction (anorgasmia and/or delayed orgasm). Three of those 5 patients had a history of treatment-emergent sexual dysfunction while receiving other antidepressant agents. Clinicians should be aware of this side effect of fluoxetine.
