[Long-term courses of anxiety disorders]

At present there is no comprehensive overview of the long-term development of the clinical picture, disease-associated impairments and neurobiological correlates of anxiety disorders as well as what influence certain risk factors and treatment have on the prognosis.

This article presents findings regarding disorder-specific symptoms and disorder-associated changes in the areas of functional level, quality of life, neurocognitive performance and structural brain anatomy over the lifespan. It also reports on how patient-related and environment-related aspects as well as guideline-oriented therapy influence the course of the disorder.

A literature search was conducted in PubMed on the aspects of individual components. Meta-analyses, longitudinal and cohort studies were included. To illustrate changes over time, the findings were predominantly presented separately for children and adolescents as well as for early and late adulthood.

Anxiety disorders primarily exhibit age-associated differences in the symptom profile but also in the areas of functional level and quality of life. Risk factors for an unfavorable course of the disorder were identified particularly for young and middle-aged people; however, the findings indicate that evidence-based psychotherapy or pharmacotherapy also has a lasting effect even after termination.

For long-term therapeutic success, age-dependent characteristics and limitations as well as prognostically relevant aspects in the diagnostics and treatment of anxiety disorders should be taken into consideration and treatment should be started as soon as possible.
