Aging adults, particularly those living alone, are at risk due to potential changes in their physical, mental and sensory capabilities. How can you tell if your loved one's needs have changed? Here are some clear warning signs that a specialized geriatric assessment may be in order:

1. Mail and bills are piling up. A once-conscientious older adult now finds the task of opening and sorting mail or managing a checking account too much to handle.
2. Decline in housekeeping. A formerly well-kept house now appears cluttered and dirty.
3. No food in the refrigerator: food is uneaten or spoiled. Shopping, cooking and eating sometimes become too difficult. The older adult might eat just enough to get by — often sweets or nutritionally poor foods. Weight loss is another warning sign.
4. Scorched pots and pans. Older adults with short-term memory loss may forget about pans on the stove and create a fire hazard that threatens their safety as well as the entire neighborhood.
5. Personal hygiene lapses. The person may wear the same clothing over and over again. Bathing and laundry become physically challenging. There may be a fear of falling in the tub or tripping on the stairs if the washing machine is in the basement.
6. Missed doctor appointments. This may be due to memory loss, lack of transportation or an inability to access ride options.
7. Repeated phone calls at unusual hours. This may be a cry for help and a sign of depression and isolation.
8. Forgetting to take medication or medication errors. This isn't just a quality of life problem — it's a dangerous situation that can have life-threatening results.
9. Inappropriate behavior, clothing or speech. You may hear about these episodes from a concerned neighbor or friend.
10. Symptoms of depression, a common disorder in older adults. Signs include feelings of hopelessness and despair, crying spells, marked changes in behavior and routine, lack of interest in once pleasurable activities, changes in sleep patterns and changes in appetite.
