Norm (2008)

Norm is a love story pure and simple. But there is nothing simple about it. A loving sister decides to take her older brother with Down syndrome into her home to provide the care and the sense of family she feels he has been denied since childhood. Like many aging adults living with Down syndrome, he begins to experience the symptoms of Alzheimer's disease. Her greatest fears have become a reality, "What if she can't keep him at home forever?"
