As the world population gets older, the number of people living with dementia is also growing.

That’s according to a new report entitled: “Dementia: a public health priority", published by the World Health Organization (WHO) and Alzheimer's Disease International.

It says that nearly 35.6 million people are living with the brain disease that leads to loss of memory.

This number is expected to double by 2030 to over 65 million and more than triple by 2050 to over 115 million.

To find out more about dementia, Derrick Mbatha spoke with Dr. Tarun Dua of WHO’s Department of Mental Health and Substance Abuse on the line from Geneva.
