Mental disorders

Dementia, particularly Alzheimer disease, are likely to become one of the leading causes of disability in the elderly worldwide. Already an estimated 29 million people suffer from dementia, and the risk of developing the condition rises steeply with age in people over 60 years. By the year 2025, Africa, Asia and Latin America between them could have more than 80 million sufferers.

At least 400 million people suffer from other mental disorders, ranging from mood and personality disorders to neurological conditions such as epilepsy, which alone is estimated to affect 40 million people.
