Screening with ECAS takes about 25-45 minutes, depending on the motor impairments of the patients. The ECAS can be performed both inĀ spoken and written form. Regarding the verbal fluency, different scoring tables are available for the written and spoken version. It can be performed by neuropsychologists, medical doctors, nurses or other instructed clinical staff. A stopwatch and a pencil are needed (a calculator can be helpful for later evaluation).
