The gap
For most brain and memory conditions, treatment works best early, but patients are usually caught only once the decline is plain to see. Doctors can confirm what's happening now. What they're missing is when.
Scans, lab results, and memory tests describe the state a patient is in right now. Useful, but backward-looking. By the time the signs are clear, the window to act has often closed.
Aro shows how a patient is likely to do across the years ahead, clearly enough that treatment and planning can start while they still make a difference.
