I think this is a reason the name. Although cast steel is also produced by pig iron, but cast steel has lower content of carbon element. So, scientifically speaking, if the carbon content is upper 2%, then it should be called as cast iron, but if lower than 2%, then it should be called as cast steel.
Depending on the type of dementia, the person's behavior may eventually become out of control. The person may become angry, agitated, and combative or clingy and childlike. He or she may wander and become lost. These problems can make it difficult for family members or others to continue providing care at home.
Knowing how long a person with dementia might survive is important for caregivers and health policymakers. People with Alzheimerâs and other forms of dementia have markedly decreased life expectancies. They are two to four times more likely to die than someone of the same age who does not have dementia.
