A Case Report of Primary Derealization Disorder: Diagnostic and Treatment Challenges in a Pakistani Healthcare Setting.

Depersonalization and derealization symptoms are often transient. Recurrent and persistent symptoms can result in a diagnosis of depersonalization/derealization disorder (DDD). Here, we reported a case of a 24-year-old adult male whose presentation was consistent with primary derealization disorder only. He was referred with his consent by an ophthalmologist and neurologist for psychiatric opinion for the complaints of blackish discoloration of his vision for the last two years and feeling of unreality towards his surroundings for the last one and a half years in the absence of any comorbid physical illness and mental disorder. The patient was treated with fluoxetine, Lamotrigine, and psychotherapy, but there was only some improvement reported in his distress; however, primary complaints remained unchanged.
