Professor Brian Cox and our expert panel explore the science of Alzheimer’s, Parkinson’s and other conditions that cause dementia.

More than 55 million people around the world are living with dementia, with the number set to rise in ageing populations. How close are we to effective, affordable treatments?  What are the genetic risks? Can we prevent it developing?

The panel takes a deep dive into dementia research and where it’s headed, from early detection to the latest drug trials and whether diet, exercise or even doing puzzles like Sudoku really make a difference.
