|Short Description of Instrument||
The Edinburgh Cognitive and Behavioral ALS Screen (ECAS) (Abrahams, et al., 2014) is a brief (15–20 minute) assessment of specific cognitive and behavioral changes that is designed to identify people living with ALS from those living with other Motor Neuron Diseases (MND). The ECAS is useful in that it can measure changes in thinking, language, memory, and behavior in people with ALS while also measuring for these changes in other neurological diseases.
Niven et al. (2015) validated the ECAS ALS Specific domains (fluency, executive function and social cognition, language), and ECAS ALS Non-specific domains (memory, visuospatial function) against five domains of the gold standard of extensive neuropsychological assessments (verbal fluency, executive function, language, memory and visuospatial function) and showed "that the ECAS is a screening tool with high sensitivity and specificity to impairment characteristics of ALS." (Niven et al., 2015).
A stopwatch and calculator are recommended to complete this test.
ALS Specific functions consist of the total score (range: 0– 100) of Executive Function (score range: 0–48); Language (score range: 0–28); and Verbal Fluency (score range: 0–24). ALS Non-Specific functions consist of a total score (range: 0–36) of Memory (score range: 0–24) and Visuospatial Functions (score range: 0–12). The ECAS total score is the combined score of ALS Specific and ALS Non- Specific scores. The cut-off score is based on 2 SD from the mean. A score that is at or below this value indicates impairment (Abrahams et al., 2014).
