Neurologic disease of<unk>  disease is classified into parenchymal or non-parenchymal. Parenchymal disease is due to lesions in the corticospinal tract, brainstem, periventricular white matter, spinal cord, and basal ganglia. Focal parenchymal lesions and complications of vascular thrombosis are the most common abnormalities. Progressive personality change, psychiatric disorders, and dementia may develop. Parenchymal disease may be divided into acute and chronic progressive neuro-Behçet syndrome. Central nervous system lesions are detectable with MRI. In the chronic phase, lesions may be smaller or resolve, atrophy may be present, nonspecific white matter lesions may be present, and lesions usually do not enhance. Cerebrospinal fluid (CSF) may show increased protein and increased cells, and neutrophils may predominate. Non-parenchymal disease of<unk>  disease include cerebral venous thrombosis, intracranial hypertension syndrome (pseudotumor cerebri), acute meningeal syndrome, and uncommonly stroke due to arterial thrombosis, dissection, or aneurysm. On average, a period of approximately five to six years elapsed between the onset of the earliest non-neurologic symptoms of<unk>  syndrome and the appearance of neurologic symptoms or findings.
