Psychiatric symptoms in patients with asthma causality, comorbidity, or shared genetic etiology.
Despite the range of diverse studies that attempt to understand the comorbidity of asthma and psychiatric diagnoses, it is still not possible to provide a reliable quantitative estimate of the increased risk for anxiety and mood disorders in children with asthma. A new hypothesis for this comorbidity has evolved, however. It is likely that the stress of having a chronic illness increases the likelihood of the development of anxiety and depressive symptoms. If this were a sufficient etiologic explanation, however, increased comorbidities of psychiatric illnesses would be found in all chronic pediatric illnesses. More precise prevalence estimates of these comorbidities require the completion of large studies that use a longitudinal design and reliable and well-validated assessment instruments. The most promising direction for future research is the definition of underlying genetic vulnerabilities that reflect autonomic regulation, may contribute to the onset of some forms of asthma, and are associated with increased risk for anxiety and mood disorders.
