If you’re referring to subtle changes that can appear when an older person is becoming frailer or medically vulnerable, four changes deserve particular attention:
-
A noticeable decline in mobility — walking more slowly, needing furniture for support, having difficulty getting out of a chair, or experiencing repeated falls.
-
Loss of appetite or unintentional weight loss — eating considerably less or becoming noticeably thinner can signal illness, medication problems, depression, or frailty.
-
Increasing confusion or changes in behavior — new memory problems, withdrawal, unusual sleepiness, or difficulty managing familiar activities shouldn’t simply be dismissed as “old age.”
-
Reduced ability to manage everyday life — difficulty bathing, dressing, preparing food, taking medicines, or maintaining the home can indicate a significant change in independence.
When to act quickly
Some changes need urgent medical assessment, particularly sudden confusion, sudden weakness, difficulty speaking, chest pain, severe breathlessness, fainting, or a sudden inability to walk.
Most importantly, look for a change from the person’s usual baseline. Gradual aging is different from a sudden or accelerating decline, and many causes of deterioration are treatable.
