Persons with dementia may not understand instructions on how to do something, not recognize objects or know how to handle them, or get frustrated when they struggle with something. It is, therefore, important to stay calm and supportive while you are assisting them. 

To help the loved one with dementia with ADLs, plan the activity, and break the tasks into smaller steps the person can understand. Keep your explanation of what needs to be done simple and brief. Avoid giving many choices or asking too many questions. Help the person start the task and show appreciation when they complete the task.
