When the evening plan suddenly stops working

You know her usual evening pattern. She may ask for home, gather her purse or check the front door. You have learned what helps: a snack, a familiar task, a brighter room or your steady company.

Then one evening, none of it works.

Mom is far more restless than usual. She cannot settle in the chair she always chooses. She keeps standing, pulling at her clothes or returning to the door. The change matters because dementia may make it hard for her to explain pain, thirst, fear or another need. A sudden change should not automatically be treated as another difficult evening. The National Institute on Aging advises families to pay attention when behavior changes suddenly or becomes much worse. See the cited guidance on the Sources page.

First, compare tonight with her usual evening

Ask yourself one clear question: Is this familiar, or is it different?

Look for a change in when the restlessness began, how strong it is and what Mom is doing. Perhaps she normally circles the hallway but now cannot sit at all. Perhaps she usually accepts supper but now pushes it away. Perhaps she asks for home every evening but tonight does not seem to know you.

Write down what you see in ordinary words. Include when it began and what happened just before it. A short note such as "stood up repeatedly after supper, would not drink, held right side" will be more useful than "bad night." The National Institute on Aging recommends watching for signs of illness and reporting what you observe because a person with dementia may not be able to say what is wrong. See Sources.

Check the simple needs Mom may not be able to name

Move through the room slowly and check one thing at a time:

Does she need the bathroom? Has she eaten? Is water within reach? Is she too warm or cold? Are her shoes, waistband or hearing aids bothering her? Does she wince, guard one part of her body, keep changing position or refuse food? Is the television loud? Are several people talking at once? Has furniture been moved, or is a dark window reflecting the room back at her?

Pain, tiredness, hunger, thirst, too much noise and changes in a familiar routine can all show up as restlessness or distress. The National Institute on Aging and the Alzheimer's Association both advise looking for a reason behind a behavior and reducing noise and confusion when possible. See Sources.

Offer help without turning the check into an interrogation. Try one quiet invitation: "Come sit with me while I get you some water." If she refuses, pause. Change the setting or the activity, then try again. Being pressed to answer questions or complete a task she can no longer make sense of may add to her distress. Source guidance is listed on the Sources page.

Look for what changed before the evening changed

Think back over the day. Was there a new medicine, a missed dose or a different time for a usual medicine? Was sleep poor? Did she eat or drink less? Did she fall, bump into something or spend time somewhere unfamiliar? Is a regular companion away? Was the house unusually busy?

Do not change or stop a medicine on your own. Write down the medicine name, what was different and when the new behavior began. The National Institute on Aging advises contacting the person who prescribed a medicine about unusual changes and keeping an accurate medicine list. See Sources.

Know when tonight needs a call

Call Mom's doctor or the after-hours number when the change is sudden, much stronger than her familiar evening pattern or paired with signs that she may be unwell. Say exactly what is new. Mention changes in eating, drinking, sleep, bathroom use, walking, speech, breathing, balance and medicine. Ask, "Does she need to be checked tonight, or what should I watch for until morning?"

Call 911 if Mom is in immediate danger, has collapsed, cannot breathe normally, has a sudden new problem speaking or moving, or you cannot keep her or anyone else safe. Tell the dispatcher that she has dementia and that this behavior is not usual for her.

The National Institute on Aging says sudden or rapidly changing behavior can be connected with illness, discomfort, dehydration or medicine changes and should be brought promptly to a doctor's attention. Its emergency guidance also tells families to describe the events leading up to the change. See Sources.

Keep the doorway covered while you work out what is wrong

A new problem does not cancel the leaving risk. If Mom is moving toward the door, have one person stay with her while another makes calls, checks the medicine list or looks for the after-hours number. Put car keys out of sight. Check every outside door before attention shifts to the phone.

If you are alone, keep Mom with you. Sit near the exit if that is where she wants to be. You do not have to win an argument about where she lives before you ask for help.

The Alzheimer's Association recommends watching for changes such as increased pacing, repeated movements, difficulty finding familiar rooms and attempts to meet old obligations. It also advises planning around the time of day when leaving is most likely and using door alerts as one part of the home plan. See Sources.

Make tomorrow easier to read

Keep a small evening record for several days. Note the first sign, what Mom had eaten and drunk, bathroom use, sleep, medicines, visitors, noise, changes to the room and what helped. You are looking for a repeatable pattern, not a perfect explanation.

Share the record with everyone who covers dusk. Agree on the line that means someone calls for help, such as a sudden change from Mom's usual behavior or a new sign that she may be hurting. Put the doctor, after-hours contact and emergency information where the evening helper can find them.

If tonight looks like Mom's familiar late-day pattern rather than a sudden change, continue with Start Here: Dusk to Morning, in Order. If your family needs another person to help think through the next step, use Lifelines: Dementia Help in St. Louis.

The useful early warning is not simply that Mom is restless. It is that she is different from herself. Notice that difference, protect the doorway and describe what you see. You do not have to solve the cause before you ask for help.
