Aim: Several tests are available for aphasia screening following stroke. However, some of them have shortcomings such as need of specialist knowledge, low sensitivity and/or specificity and lengthy administration time. Our study aims at evaluating the language component of the Addenbrooke’s Cognitive Examination – Revised (ACE-R) as a screening tool for aphasia in stroke patients.
Methods: The language component of ACE-R was administered to consecutive patients admitted to a post-acute stroke unit. Patients who are medically unstable, having significant history of sensory impairment or mental health issues were excluded. The test was administered by two junior doctors with basic training in ACE-R administration. Patients recruited were also assessed by an experienced speech and language therapist (SLT). The results of the two assessments were documented by a different member of the team and The SLT results were used as the benchmark to calculate the ACE-R language component sensitivity and specificity.
Results: Fifty-nine participants were recruited and 27 of them were female. The mean age was 72 (SD 11.9). Thirty-four participants had left and 11 right hemisphere stroke. Fourteen had bilateral affection. Six participants were left handed. A cut-off value of 22/26 of ACE-R language component showed 100% specificity and 83.1% sensitivity. While a cut-off value of 16/26 had 88.2% specificity and 100% sensitivity.
Conclusion: Our results suggest that the language component of ACE-R has a satisfactory sensitivity and specificity compared with other screening tests used in strokes. It is easy to administer and free to use.
