Attention is a mental control system that lets you adjust how hard you think about something.
Because brain damage weakens attention, a good recovery depends on deliberately thinking a bit harder about many things. There is a special need to pay more attention to tasks as they get harder. Mental effort is also a self-therapy tool that can reduce or neutralize cognitive deficits. So “powering up” into maximum alertness and attention is the first step toward getting your deficits under control. When you power up, you can keep your mind focused on one topic at length, think deeply about it, and come up with your best plans and ideas. Making maximum effort sometimes offsets deficits completely, allowing survivors to function at full effectiveness.” – Larry Schutz, PhD
