(CNN)Anxiety is the most common psychological disorder affecting adults in the United States. In older people, it's associated with considerable distress as well as ill health, diminished quality of life and elevated rates of disability.
Yet when the US Preventive Services Task Force, an independent, influential panel of experts, suggested last year that adults be screened for anxiety, it left out one group — people 65 and older.
The major reason the task force cited in draft recommendations issued in September: "(T)he current evidence is insufficient to assess the balance of benefits and harms of screening for anxiety" in all older adults. (Final recommendations are expected later this year.)
The task force noted that questionnaires used to screen for anxiety may be unreliable for older adults. Screening entails evaluating people who don't have obvious symptoms of worrisome medical or psychological conditions.
