Narrator: This is Science Today. There's a tendency in medicine to take multi-disciplinary approaches to complex diseases. According to Lennart Mucke, a professor of neurology at the University of California, San Francisco, in the case of Alzheimer's Disease, it's the only way to go.
Mucke: We know that there are specific mutations. If you inherit those you do get Alzheimer's Disease, but most people get Alzheimer's Disease without having these mutations. So this goes to show that there must be other factors that can do it too. These are complicated diseases and I think they need to be tackled by many people with many different approaches and many different models.
Narrator: The problem is, multi-disciplinary resarch tends to be very costly.
Mucke: And unfortunately, even though there has been more happening in Alzheimer's Disease in the past five years, the funding hasn't grown with the enormous progress the science has made.
