Why dementia should be viewed as a disability?

People who have dementia are not aware of requirements for living. They can forget to do the essential things that are vital. Taking medicines, hygiene and even eating are often forgotten. They can get lost or hurt and not understand what is necessary to correct a situation. Turning on the stove or water and forgeting to turn it off, locking doors, crossing streets etc. can be dangerous even deadly. In the same way you would not think as an infant incapable of self care a person with dementia can not be either. Consdering the facts that they cannot act in the manner of a responsible adult makes them disabled.
