Not everyone with dementia needs 24 hour care, especially in the early stages. Some people can stay fairly independent with support during the day, reminders, and safety changes at home. As the condition advances, constant supervision may become necessary to prevent wandering, falls, medication mistakes, or distress at night. The need for 24 hour care depends on safety, memory, mobility, and behaviour. A doctor or care professional can help judge when supervision needs have become too great for part-time support alone.
