Just a pedantic wordsmith's note: "significant" does not only mean "extensive" - its more accurate meaning is "worthy of note". And worthy of note really only means that it is present, that it exists... I do not know how your Occupational Therapist (OT) meant it. It does not, in any case, alter the feeling of, as you say, actually seeing something in writing, which seems to confer the sense of an absolute, unalterable truth...
