Would you want to know if Alzheimer's was likely?

Dr Doug Brown, the Alzheimer's Society director of research and development, said people "must be given a choice about whether they would want to know, and fully understand the implications" of a test that could predict the onset of the disease.

  • Mechelle Thomson: "Only to prepare my family so they would know what to expect. A little education could go a long way."
  • Michael King: "How depressing knowing that you're going to get it in advance and being able to do little about it. I'd rather not know."
