An older adult presenting with undernutrition, slowed motor performance, and loss of muscle mass is most consistent with which condition?

• A. frailty
• B. depression
• C. Parkinson's disease
• D. Alzheimer's disease

Answer: (A)

Frailty syndrome in older adults is suggested by a combination of unintended weight loss, slowed physical performance, and loss of muscle mass. These features reflect reduced physiological reserve and increased vulnerability to stressors. Unintentional weight loss points to undernutrition, slowed motor performance corresponds to decreased gait speed or overall slowness, and loss of muscle mass (sarcopenia) is a core component. While depression, Parkinson’s disease, or Alzheimer’s disease can have overlapping features, their hallmark signs differ—mood changes for depression, tremor/rigidity and bradykinesia for Parkinson’s, and progressive cognitive decline for Alzheimer’s. The pattern described aligns best with frailty.
