Reduced cerebral perfusion may have an impact on mental performance as measured by the Benton Facial Recognition Test (BFRT). We evaluated the usefulness of BFRT in identifying cognitive decline in patients with VBI by correlating test performance with total blood flow in the vertebrobasilar system and other variables such as educational level and gender. Materials and methods: Thirty-three participants without dementia (mini-mental state examination; MMSE >27) and cranial magnetic resonance imaging abnormality, but with atherosclerotic risk factors were involved in the study. Nineteen subjects had a total vertebrobasilar flow volume less than 200 ml/min (Group I), and 14 subjects had a flow volume more than 200 ml/min (Group II). Results: The groups were similar in regard to gender, age, and educational level. BFRT results were 19.53 +/- 3.12 and 22.36 +/- 2.73 for Groups I and II, respectively (p = 0.01). The educational level was the main factor affecting the BFRT score in Group I (p = 0.04). Discussion: BFRT is clearly impaired in VBI as measured by Doppler ultrasound examination. We concluded that the test appears to adequately distinguish cognitive levels between VBI and other patients. Additionally, our results suggest that education is associated with BFRT results, and for normative purposes, gender consideration is unnecessary. Further studies are needed to investigate the association between VBI and memory dysfunction in early dementia. (C) 2013 Elsevier Ltd.
