Current screening batteries for assessing neuropsychological function are not specific for Amyotrophic Lateral Sclerosis (ALS) and are considered as limited tools due to the physical disabilities associated with ALS. The Edinburgh Cognitive and Behavioural ALS screen (ECAS) was developed to detect the specific cognitive and behavioral changes that may occur among ALS patients. This study presents the ECAS developed for Arabic-speaking ALS patients (ECAS-AR) for use by healthcare professionals. ECAS was translated and modified to refined variety of Arabic language. Eighty-five ALS patients were included. Normative data were collected from 200 healthy controls (among them 97 were matched). Subjects were administered the ECAS-AR and two conventional cognitive screening batteries, Frontal Assessment Battery (FAB) and Mini-Mental State Examination (MMSE). ECAS-AR discriminated well between healthy controls and ALS patients. Significant differences were noted in language, executive functions, memory, and visuospatial domains between the two groups. The most prevalent deficit occurred in language and executive functions in ALS-specific functions. Whereas memory was more readily impaired in the lower and middle education groups concerning ALS non-specific functions. Verbal fluency tended to be preserved. Positive correlations were found between ECAS-AR and the standard cognitive tests supporting its full validity. The ECAS-AR version proposed will provide rapid, efficient and sensitive tools for healthcare professional to determine the cognitive-behavioural profile in Arabic-speaking ALS patients.
