BACKGROUND Data on the course of anxiety in late life are scarce. The present study sets out to investigate the course of anxiety, as measured by the HADS-A (Zigmond & Snaith, 1983) in community dwelling older persons, and to evaluate predictive factors for change over 3 years in anxiety symptoms following the vulnerability/stress model. METHOD Based on the first anxiety assessment, two cohor...

Despite dramatic advances in our understanding of genetics and neurobiology, the etiology of the anxiety disorders is still relatively unknown. To date, there remain no pathognomonic markers with which a presumptive diagnosis of an anxiety disorder may be made. This highlights the importance of the empirical epidemiologic approach to investigating the definitions and risk factors for the expres...

anxiety comprises many clinical descriptions and phenotypes. a genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-ht) transporter (5-htt) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. complete genome-wide linkage s...
