What it is
The ACTIVE trial randomly assigned 2,802 people aged 65 and over to memory, reasoning or speed training, or none, and followed them through Medicare records. Two decades on, 40 percent of those who had speed training plus a few top-up sessions had a dementia diagnosis, against 49 percent with no training. The other kinds of training made no measurable difference.
Where it stands
One result among more than 20 comparisons, so it needs a trial built to test it. A later version of the task is sold commercially.
