Dementia is one of the greatest challenges we face: • 800,000 people live with dementia in the UK. This is expected to rise to 1 million by 2021. • Kent, Surrey and Sussex have the greatest proportion of older people in the country. • 50,000 people are currently diagnosed with dementia in the region. This figure is expected to rise to 75,000 by 2030. • Nationally, the cost of treatment and care for dementia is estimated to be £23bn, and there are thought to be around 670,000 unpaid family carers.
