Multiple theories of Attention-Deficit/Hyper- activity Disorder (ADHD) have been proposed, but one that has stood the test
of time is the dopamine deficit theory. We review the narrow literature from recent brain imaging and molecular genetic studies
that has improved our understanding of the role of dopamine in manifestation of symptoms of ADHD, performance deficits on
neuropsychological tasks, and response to stimulant medication that constitutes the most common treatment of this disorder.
First, we consider evidence of the presence of dopamine deficits based on the recent literature that (1) confirms abnormalities in dopamine-modulated frontal-striatal circuits, reflected
by size (smaller-than-average components) and function (hypoactivation); (2) clarifies the agonist effects of stimulant medication
on dopaminergic mechanisms at the synaptic and circuit level of analysis; and (3) challenges the most-widely accepted ADHD-related
neural abnormality in the dopamine system (higher-than-normal dopamine transporter [DAT] density). Second, we discuss possible
genetic etiologies of dopamine deficits based on recent molecular genetic literature, including (1) multiple replications that confirm the association of ADHD with
candidate genes related to the dopamine receptor D4 (DRD4) and the DAT; (2) replication of differences in performance of neuropsychological
tasks as a function of the DRD4 genotype; and (3) multiple genome-wide linkage scans that demonstrate the limitations of this
method when applied to complex disorders but implicate additional genes that may contribute to the genetic basis of ADHD.
Third, we review possible environmental etiologies of dopamine deficits based on recent studies of (1) toxic substances that may affect the dopamine system in early development and contribute substantially
to the etiology of ADHD; (2) fetal adaptations in dopamine systems in response to stress that may alter early development
with lasting effects, as proposed by the developmental origins of health and disease hypothesis; and (3) gene-environment
interactions that may moderate selective damage or adaptation of dopamine neurons. Based on these reviews, we identify critical
issues about etiologic subtypes of ADHD that may involve dopamine, discuss methods that could be used to address these issues,
and review old and new theories that may direct research in this area in the future. 相似文献

Neuropsychological methods and techniques have much to offer in the evaluation of the individual suspected as having Attention-Deficit/Hyperactivity
Disorder (ADHD). After a review of the historical evolution of the ADHD concept, incidence and prevalence, and DSM-IV criteria
for diagnosis, especially as regards omission related to gender differences, and other associated cultural, familial, socioenvironmental,
and subject influences, this paper describes a number of dilemmas and obstacles encountered in clinical practice. Included
are the confounds associated with the wide range of possible comorbidities, the insufficiency of current DSM-IV criteria,
the emergence of subtype differentiation and its impact on diagnosis and treatment. The complex relationship between neuropsychological
constructs and ADHD, and obstacles to valid assessment are also addressed. The complexities associated with a thorough ADHD
evaluation are viewed within an impressive and expansive existing scientific framework and recommendations are made for future
directions. 相似文献

The original Maudsley Obsessional Compulsive Inventory (MOCI) has been widely used and is considered to be one of the best available self-report instruments for measuring observable obsessive-compulsive problems such as washing and checking. However, it has several limitations and requires updating. Our revision of the MOCI, the Vancouver Obsessional Compulsive Inventory (VOCI), was designed to provide assessment of a range of obsessions, compulsions, avoidance behaviour, and personality characteristics of known or theoretical importance in obsessive-compulsive disorder (OCD). The development of the VOCI is described, and we provide evidence of its reliability and validity. Our findings in samples of people with OCD, people with other anxiety disorders or depression, community adults, and undergraduate students suggest that the VOCI is a promising new measure. We anticipate that, like its predecessor, the VOCI will have widespread use in both research and clinical settings. 相似文献

Although psychological and pharmacological treatment approaches for Body Dysmorphic Disorder have been evaluated, the relative effectiveness of these two types of interventions has not been examined. We conducted a meta-analysis of randomized clinical trials and case series studies involving psychological (i.e., behavioural, cognitive-behavioural, cognitive) or medication therapies. Our findings support the effectiveness of both types of therapy, but suggest that cognitive-behavioural treatment may be the most useful. These findings require cross-validation through large-scale clinical trials. 相似文献

We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who
outperformed patients with the Combined subtype. These results replicated findings of greater executive deficits in the Combined
than in the Inattentive type of ADHD. Double-blind administration of methylphenidate improved task performance only for patients
with the Inattentive subtype. In a drug-free Baseline session, children with both subtypes of ADHD made more private verbalizations
than controls, particularly when failing puzzles. In later sessions, regardless of drug condition, the inattentive sample
exhibited a smaller increase in self-regulatory utterances under failure. In contrast, the combined sample decreased self-regulatory
verbalizations under failure only under methylphenidate. The results support some differences between the two subtypes of
ADHD in executive functioning and in their response to stimulant therapy.
Portions of these results were submitted as part of H. Theresa Chang's PhD dissertation (Chang, 2000) and Helena Kopecky's
unpublished master's research, both conducted at the University of Rochester and supervised by Rafael Klorman. 相似文献

According to the norms and collective efficacy model, the levels of social connectedness within a local community are a function of neighborhood structural characteristics, such as socioeconomic status and ethnic composition. The current work aims to determine whether neighborhood structural and institutional features (neighborhood wealth, percentage of immigrants, population density, opportunities for activities and meeting places) have an impact on different components of neighborhood social connectedness (intergenerational closure, trust and reciprocity, neighborhood-based friendship and personal relationships with neighbors). The study involved a representative sample of 389 early and middle adolescents aged 11–15 years old, coming from 31 Italian neighborhoods. Using hierarchical linear modeling, our findings showed that high population density, ethnic diversity, and physical and social disorder might represent obstacles for the creation of social ties within the neighborhood. On the contrary, the presence of opportunities for activities and meeting places in the neighborhood was associated with higher levels of social connectedness among residents. 相似文献

Mothers of twenty-four noncompliant, clinic-referred, preschool children were trained to use either a warned or unwarned time-out procedure in a clinic analog setting to suppress child noncompliance to commands. Warnings respecified the command to be followed and labeled the time-out procedures were equally effective at increasing child compliance. However, warned time-out procedures were associated with fewer actual time-outs than unwarned time-out procedures. The potential benefits of warned time-out procedures are discussed and future research needs are indicated. 相似文献

The aim of this study was to investigate whether there was a difference in skin conductance response between 2 groups of military personnel when exposed to emotionally neutral and charged stimuli. The 2 groups were a combat experience group (n?=?10) with prior experience of emotionally charged war situations and a comparison group (n?=?10) with no such experience. Results showed that the comparison group reacted more strongly to exposure to both charged and neutral pictures than did the combat experience group, regardless of exposure time. The results are discussed in terms of emotional numbing and differences in anxiety state between the 2 groups. 相似文献

This study explored the feasibility of using Internet social networking media in an online program for Major Depressive Disorder (MDD) screening and psychoeducation targeting college students. A Facebook advertisement targeted students at five colleges in the United States to complete a mental health research survey that screened for MDD using the Patient Health Questionnaire-9 (PHQ-9). Students who screened positive for MDD were offered an eightweek follow-up survey. Of the 259 students who consented to participate in the study, 26.7% screened positive for MDD, while only 14.2% were receiving treatment. The use of Facebook to advertise for online screening for MDD required very little start-up time, and the average cost was $11.45 per subject recruited. It is feasible to use online, commercially available social networking media such as Facebook for online screening for MDD among college students. However, conducting online screening and offering treatment resources alone did not increase treatment rate in this population. 相似文献
