An older adult presenting with signs of undernourishment, slowed motor performance, and loss of muscle mass or weakness suggests:

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

Answer: (B)

Frailty is the pattern here. It describes a state of reduced physiologic reserve in older adults, leading to greater vulnerability to stressors. The combination of undernutrition, slowed motor performance (slower gait or movement), and loss of muscle mass fits the typical frailty picture, often with sarcopenia contributing to weakness. This constellation signals a systemic, mobility-related vulnerability rather than a primary mood disorder, cognitive disorder, or a parkinsonian syndrome. Depression can cause appetite changes and psychomotor slowing but doesn’t usually include clear, objective muscle mass loss; Parkinson’s disease features tremor, rigidity, and postural issues; Alzheimer’s disease centers on cognitive decline. Frailty, however, explains the physical weakness and slowed function seen in these signs and carries implications for risks like falls and disability.
