57 million people live with dementia today. By 2050, more than twice as many will.
Behind them are hundreds of millions of adults in midlife who carry modifiable dementia risk – and almost none of them are given anything to act on. In the United States, more than four in ten people over 55 will develop dementia in their lifetime.

In the quiet years.
Long before anything is felt or measured, the changes that lead to dementia start to build. That is the stretch Tolion is made for – daily, personal guidance on the risk factors a person can change, each one pushing the curve later.
