- Objectives: To compare two methods for brief assessment of cognitive functions in a neurorehabilitation setting. The Mini Mental State Examination (MMSE) is a well-known instrument for a brief, structured assessment of cognitive function. A more recent instrument, the Barrow Neurological Institute Screen for Higher Cerebral Functions was constructed to cover a broad range of cognitive functions including aspects of affect and awareness. Materials&Methods: 52 patients with neurological diagnosis (stroke, traumatic brain injury, anoxic brain injury, Parkinson´s disease) were assessed with the MMSE and the BNIS. Concordance of the scales was assessed with Goodman-Kruskal´s gamma and scale structure (parallel reliability) was explored with Rank Transformable Pattern of Agreement (RTPA). A linking to the ICF at item-level was performed. Results: 36 men and 16 women (median age 52 years) were recruited. Median number of days between admittance to hospital and screening was 47 (MMSE) and 51 (BNIS). Concordance between the two instruments was good with a gamma coefficient of 0.724 (p=0.0005). RTPA identified different width of the scale steps showing that BNIS discriminated between the subjects that reached the high end of the MMSE scale and MMSE discriminated somewhat better between individuals with lower scores. The MMSE covered 12 ICF categories on Body function and 14 on Activities and Participation. BNIS covered 18 categories on Body functions and 16 on Activities and Participation. Conclusion: The concordance between MMSE and BNIS was good but the scales are not completely interchangeable. The BNIS differentiated those who reached the ceiling on MMSE. More ICF categories on Body function were assessed with the BNIS which might explain this.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To determine whether the Barrow Neurological Institute Screen for Higher Cerebral Functions (BNIS) can differentiate brain-dysfunctional patients from controls. DESIGN: A case-control study. SUBJECTS: A total of 92 controls and 120 patients from a neuro-rehabilitation clinic with a diagnosis of: right and left hemisphere stroke, traumatic brain injury, Parkinson's disease or anoxic brain damage. METHODS: The BNIS has a maximum total score of 50 points, < 47 indicates cognitive dysfunction. Group comparisons and exploration of variables influencing the BNIS total score were made. RESULTS: A significant difference was found between the control group and the total patient group for the BNIS total score and for the subscales (p < 0.0005). Sensitivity was 88% and specificity 78%. Presence of disease and educational level had the greatest influence on the results of the BNIS. Patients with Parkinson's disease were shown to be the least cognitively affected and those with anoxic brain damage the most affected. CONCLUSION: The BNIS has potential value as a screening instrument for cognitive functions and is sufficiently sensitive to differentiate brain-dysfunctional patients from a control population. It appears to be applicable in a neurological rehabilitation setting, and can be used early in the process, giving a baseline cognitive functional level.
