Abstract: Neuro-Behcet's disease (NBD) presents cognitive and behavioral symptoms possibly explained by secondary dysfunction of frontal and temporal cortices due to subcortical damage, as NBD commonly involves the brainstem and basal ganglia. Nonetheless, there are reports of cognitive impairment in patients without neurological manifestations.Objective: To evaluate cognitive function in Behcet's disease (BD) patients with and without neurological manifestations and to analyze clinical variables associated with cognitive deficits.Methods: This is a cross-sectional study that compared healthy controls, BD patients without neurological manifestations and NBD patients. Each group comprised 24 participants. All participants underwent neuropsychological evaluation, Hamilton Anxiety Rating Scale (HAM-A), Beck Depression Inventory (BDI) application and brain MRI. Cumulative prednisone dose, years of education, and presence of white-matter lesions in brain MRI were recorded.Results: 41.6% of BD and 41.6% of NBD patients showed impaired language and executive function, whereas visual memory was impaired only in NBD patients. Multiple logistic regression revealed that anxiety (OR 1.09 95% CI 1.03-1.16, p = 0.003) and lower educational level (OR 0.62 95% CI 0.48-0.80, p<0.0001) were independently associated with cognitive impairment.Conclusion: Cognitive impairment occurs frequently in patients with BD independently of neurological manifestation. Low educational level and anxiety are risk factors for cognitive impairment in BD. (c) 2013 Elsevier B.V. All rights reserved.
