Neurological Manifestations of Dengue Infection

Background: The clinical profile of dengue fever (DF) is changing and neurological manifestations are being reported more frequently. The exact incidence of various neurological complications is uncertain. Objectives: The aim of this study was to observe the neurological manifestations in dengue infection. Materials and Methods: In this prospective study, 263 confirmed cases of dengue infection were observed for neurological complications. Detailed clinical examination and investigations were done to detect any neurological involvement in dengue infection. Result: In this study, neurological complication was seen in 8.3% (22/263) of patients. The most common neurological manifestation was seizure, seen in 54.54% (12/22) of cases, followed by encephalopathy and meningitis, each of which was seen in 18.18% (4/22) of the cases. The other manifestation was intracerebral hemorrhage, seen in 9.09% (2/22) of cases. Conclusion: The study findings could potentially be explored for a better understanding of neurological complications of dengue infection in endemic areas.
