141,000 people in New Zealand have dementia, and that number is set to double over the next 20 years as a result of an aging population. The most common form of dementia is Alzheimer's Disease, typified by memory loss, a growing inability to care for oneself, and ultimately death. But people with dementia say stereotypical image of a helpless, frail pensioner works against them, causing stigma and alienation. In the first programme of a two-part series on dementia, Sue Ingram talks to those affected by the disease and finds out from them and their carers how life and relationships have changed.
