The Cog-Log is a ten-item scale designed for serial bedside measurement of cognitive functions in individuals completing inpatient rehabilitation. The scale includes items assessing orientation, immediate and delayed verbal recall, concentration, executive function, response inhibition, and praxis. All responses are scored according to the following criteria: 3 points = spontaneously correct response, no errors; 2 points = correct on logical cueing (e.g., “That was yesterday, so today is?”) or in the presence of 1 error; 1 point = correct on multiple-choice cueing or in the presence of 2 errors; and 0 points = incorrect despite cueing, more than 2 errors, unable to complete. Points for time estimation are calculated as follows: 3 points = correct within ±5 s; 2 points = correct within ±10 s; and 1 point = correct within ±15 s. Incorrect/absent responses are followed by cueing at the next level for the orientation and delayed memory items....
