Module 4 Lesson 4. Personal care Modifying the environment to make personal care easier There are different reasons for not being able to perform personal care. One reason is that people with dementia may not find the things that they need for personal care. For example, when you cannot find your toothbrush and toothpaste due to memory loss, it will be difficult to brush your teeth. However, you can modify the environment to make it easier for them to find things that are needed for personal care.
