A documentary focusing on Alzheimer's research is to be screened in the US, reports say.
"Filling the Blank", created by Cable News Network will feature the research of professor Kenneth S. Kosik of the University of California, Santa Barbara.
"This type of early onset Alzheimer's disease is very poignant," said Kosik.
"People in their mid-40's have textbook memory loss. And, they lose the ability to take care of themselves. We often see a parent caring for a middle-aged son or daughter with the disease."
The film will follow scientists and they track the 20 year history of the condition in an extended family in Columbia which has the largest cluster of familial Alzheimer's disease in the world.
According to the research, family members develop the disease in their mid-40s and if they carry the gene, they will definitely get Alzheimer's.
Meanwhile, Rebecca Wood, chief executive of the Alzheimer's Research Trust has said that more research should be done into understanding the cause of dementia.
