Memory problems may be part of the reason for incontinence.
Here is some advice on how to help your loved one:
Follow a toileting schedule, so the person never has an urgent need.
Try a sign on the door: “BATHROOM”.
At night, illuminate the pathway to the bathroom with lights or tape that glows in the dark.
Paint bathroom walls a contrasting color to the toilet so that it stands out.
Make sure complicated belt buckles and tight clothing aren’t slowing the person down.
Minimize evening color, coffee, and tea.
If persistent accidents are a problem, get medical advice.
