Evaluación función cerebral de pacientes con EM

Dres. S. Vanotti, A. Alonso y equipo

Dado que no hay consenso con respecto a la evaluación del sistema funcional de la función cerebral (FS) de la Escala de estado de discapacidad expandida (EDSS) en pacientes con Esclerosis Múltiple (EM) el estudio intenta describir los criterios de evaluación de FS de la función cerebral utilizados por los neurólogos argentinos y, en base a los resultados, proponer criterios redefinidos de FS de la función cerebral.
Los resultados mostraron la importancia de unificar los criterios de puntuación FS de la función cerebral al calcular la puntuación EDSS.

Background:

There is no consensus regarding assessment of the brain function functional system (FS) of the Expanded Disability Status Scale (EDSS) in patients with multiple sclerosis (MS). We sought to describe brain function FS assessment criteria used by Argentinian neurologists and, based on the results, propose redefined brain function FS criteria.

Methods:

A structured survey was conducted of 113 Argentinian neurologists. Considering the survey results, we decided to redefine the brain function FS scoring using the Brief International Cognitive Assessment for MS (BICAMS) battery. For 120 adult patients with MS we calculated the EDSS score without brain function FS (basal EDSS) and compared it with the EDSS score after adding the modified brain function FS (modified EDSS).

Results: Of the 93 neurologists analyzed, 14% reported that they did not assess brain function FS, 35% reported that they assessed it through a nonstructured interview, and the remainder used other tools. Significant differences were found in EDSS scores before and after the inclusion of BICAMS (P< .001). Redefining the brain function FS, 15% of patients modified their basal EDSS score, as did 20% of those with a score of 4.0 or less.

Conclusions:

The survey results show the importance of unifying the brain function FS scoring criteria in calculating the EDSS score. While allowing more consistent brain function FS scoring, including the modified brain function FS led to a change in EDSS score in many patients, particularly in the lower range of EDSS scores. Considering the relevance of the EDSS for monitoring patients with MS and for decision making, it is imperative to further validate the modified brain function FS scoring. I
