Specific association of worry with amyloid- β but not tau in cognitively unimpaired older adults

Anxiety disorders are the most common class of psychiatric disorders across the lifespan, with a prevalence of 15% among older US adults (1). Anxiety symptoms at subsyndromal levels are even more common than anxiety disorders in late life and comprise somatic (e.g. tension), emotional (e.g., upset), cognitive (e.g. worry) and behavioral (e.g. avoidance) symptoms (2,3). Worry may be a particularly salient symptom of anxiety in late life, as excessive worry, defined by structured psychiatric evaluation, was reported by 37% of over 2,000 older adult participants in an urban, community sample (4).
