MCI of different etiologies differ on the Cognitive Assessment Battery

Objectives The study aims to investigate whether patients with mild cognitive impairment (MCI) who have significant vascular disease (MCI‐vas) differ from those with no significant vascular disease (MCI‐nov) in terms of cognitive profile when assessed with the cognitive assessment battery (CAB). Materials and methods Seventy patients clinically diagnosed with MCI were included in the study, 32 were classified as MCI‐vas, and 38 as MCI‐nov, together with 40 healthy controls. CAB consists of six short tests measuring speed and attention, memory, visuospatial functions, language, and executive functions. Results The healthy controls performed better than both MCI groups on CAB. MCI‐vas patients were significantly older and had fewer years of education than MCI‐nov patients. When adjusted for age and education, MCI‐vas performed significantly worse than MCI‐nov on memory, language, and executive tests. Conclusions The results suggest that CAB can differentiate between MCI patients with and without vascular disease and that their cognitive profiles differ. Furthermore, CAB classified the patients as vascular and non‐vascular MCI with good sensitivity and specificity.
