Which disease has the latest explicitly documented upper age bound (70 years)?

• A. Abdominal aortic aneurysm
• B. Paget's disease
• C. Spinal stenosis
• D. Rheumatoid arthritis

Answer: (A)

Screening guidelines sometimes set an explicit upper age bound to balance the potential benefit of detecting disease against the risks and competing mortality in older patients. Abdominal aortic aneurysm screening has the clearest upper-age guidance in the literature. Many guidelines recommend ultrasound screening for men up to around 70–75 years old, with 70 often cited as the latest explicitly documented upper bound in some sources. Beyond that age, the net benefit of screening declines due to shorter remaining life expectancy and higher procedural risks, so routine screening is not typically recommended. The other conditions listed do not have a universally stated upper age limit for screening or routine evaluation. They can present across a wide age range, and guidelines do not specify a fixed maximum age for assessment.
