This course from University College London provides an eye-opening breakdown of a few of the less-often discussed forms of dementia, the challenges of caring for someone with the disease, and the progress that has been made in treatment.

Dementia is not a single condition, but an umbrella term for a group of diseases like Alzheimer's that target the brain in different ways.

And as the global population ages, dementia has become one of the most feared and least understood conditions affecting us today.

In this course, experts from University College London provide insight into current dementia studies from clinical and personal perspectives.

Chris Hardy is a postdoctoral research fellow at the Dementia Research Centre, while Claire Waddington is a research assistant and support worker at Rare Dementia Support.

The Many Faces of Dementia follows the stories of four people with lesser-known forms of dementia.

While there is still no cure for dementia, prognosis and treatments vary for each type, and research continues to advance.
