Behcet’s Disease (BD) is chronic, multisystem inflammatory disorder with vasculitis as the
underlying process and most commonly affects the brain stem with a patchy involvement of
upper parts in the nervous system. Although predominant mental symptoms are the main forms
of nervous system involvement, mental changes and psychiatric problems are seen at later stages
of BD. We report a case with Behcet’s disease initially presented with depression and dementia.
The most prominent findings were depression and cognitive impairement with gait ataxia. This
case was treated with steroids, serotonin selective reuptake inhibitors and memantin. The initial
presentation of memory problems and depression in neurological involvements of BD have not
yet been reported in literature. Therefore, our case who had an onset with psychiatric complaints
and memory problems is an interesting one.
