Beyond the Usual Features-Expanded Dengue Syndrome in Association With Possible Pre-existing Neurological Disease: A Case Report.

Dengue virus infection is a significant public health concern, particularly in endemic areas. This case report highlights the difficulties in diagnosing expanded dengue syndrome (EDS) in a dengue-endemic region. This case report emphasizes keeping high suspicion of index for (EDS) among patients presenting with fever and neurological manifestations particularly in regions where dengue is endemic. The atypical neurological symptoms and inconclusive initial investigations underscore the diagnostic challenges associated with (EDS). Prompt recognition and appropriate laboratory testing, such as detecting dengue NS1 antigen, can aid in accurate diagnosis and subsequent management of patients with this condition. Increased awareness among healthcare providers in endemic regions is crucial for timely identification and intervention in case of dengue-associated neurological complications. Therefore, a multidisciplinary approach is required for time-effective management.
