Popis: The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is used to screen for dementia in many Wisconsin Alzheimer Institute memory care clinics. After observing a pattern of lower scores for immediate memory than for delayed memory (immediate memorydelayed memory) that seemed to predict obstructive sleep apnea in patients seen in our memory care clinic, we aimed to confirm the validity of this finding.We retrospectively identified all patients seen in our memory care clinic from December 2011 through December 2014 who completed the RBANS. The frequency of obstructive sleep apnea was determined among those with the pattern of interest (immediate memorydelayed memory).Among 191 patients who met the inclusion criteria, 81 (42%) displayed the immediate memorydelayed memory pattern. Of these, 54 patients had been or were subsequently tested for obstructive sleep apnea; 35 (65%) were positive. In the positive group, the mean age was 74 years; 60% were women.Obstructive sleep apnea is a known risk factor for cognitive dysfunction. It is a potentially treatable cause of memory loss that can be clinically silent. This study shows that a unique pattern (immediate memorydelayed memory) on the RBANS commonly used at memory care clinics can identify a group of patients who can be evaluated and treated for this common and remediable condition.
