Introduction: Various reports have revealed a cognitive dysfunction in Behçet’s disease (BD). In this study, we aimed to assess the silent neurological manifestations, behavioral, and neuropsychiological impairments of Behçet’s disease patients with ocular involvement. 


Methods: Thirty BD patients with ocular involvement in the nonactive phase of their illness were applied detailed neurological examination and magnetic resonance imagining (MRI). Neuropsychological tests were performed. Patients’ neuropsychological performances were compared to those of healthy demographically matched twenty subjects. 


Results: Neurological manifestations of patients were headache (56.6%), pyramidal signs (13.3%), behavioral changes (3.3%) and sensory symptoms (3.3%). Four patients (13.3%) had white matter hyperintensities lesions on T2/FLAIR brain MRI. Fourteen patients (46%) had impaired cognitive performances on the following tasks: verbal memory (immediate memory, maximal learning capacity, number of repetitions, total learning capacity, recall, nonverbal memory (immediate memory, recall, logical memory (immediate memory, recall), executive (frontal) functions (clock-drawing test, Stroop test, verbal fluency tests), (p<0.05). Patients’ MMSE and clock drawing test scores were significantly lower than controls. Attention deficit was not detected. Behçet’s disease patients showed higher scores on depression scales than healthy subjects but there was no statistically significant difference between anxiety scores.


Conclusion: Neuropsychological deficits, involving mainly memory and executive functioning, subcortical MRI lesions and non-structural headache may be present in Behçet’s disease patients with ocular involvement without overt neurological manifestations.
