The goal of the current work is to provide a comprehensive review and interpretation of the literature on the human and economic burden of generalized anxiety disorder (GAD) and how it compares with that of other mental disorders. The term "human burden" is used to describe quantified impairments in role functioning and quality of life (QOL). "Economic burden" describes costs related to health care resource utilization and lost work. A review of 34 studies reporting original quantitative data on associations between GAD and role functioning, QOL, and/or economic costs was undertaken. GAD was defined by DMS-III-R, DSM-IV, or ICD-10 DCR. Persons with GAD (both with and without a comorbid mental disorder) described significant impairments due to both physical and emotional problems. Studies typically showed that role and QOL impairments of GAD were at least comparable in magnitude to those of other anxiety disorders, somatoform disorders, and physical conditions, and greater than those of substance use disorders. Large representative studies showed that role impairments of pure GAD were similar in magnitude to those of pure MDD. Studies of DSM-IV disorders showed that QOL impairments of GAD were at least comparable in magnitude to those of MDD; studies of DSM-III-R disorders showed the opposite pattern. GAD was associated with considerable economic costs owing to lost work productivity and high medical resource use. Quality of care initiatives that have been implemented to increase recognition and improve treatment outcomes for persons with MDD should be extended to the effective management of GAD.
Anxiety disorder (ANX) is characterized by heightened arousal, psychosocial and academic difficulties, and comorbidity with other disorders, in particular, attention-deficit/hyperactivity disorder (ADHD). The heightened arousal contributes to cognitive impairment by adversely affecting executive control of cognition. The nature of the effect on executive control is poorly understood. Research in this area could inform intervention, diagnostic, and etiological research. Our objective was to characterize children with ANX on measures of executive functioning, while controlling for comorbid ADHD. We compared children ages 6-14 with ANX (N=21), ADHD (N=78), ANX+ADHD (N=38), and normal controls (NC; N=40) on the stop task, a measure of performance monitoring and response inhibition. No difference was observed between NC and ANX groups in performance monitoring. Compared to the NC group, the three clinical groups showed inhibition deficits, and both ADHD and ANX+ADHD groups monitored less after responses. ANX was not associated with performance monitoring or inhibition deficits once comorbid ADHD was considered. This emphasizes the importance of controlling for comorbid ADHD in studies of cognition and anxiety.
