Dengue is an important vector-borne tropical illness with prominent neurological involvement.The aim of this study is to evaluate the incidence,clinical and neuroimaging characteristics of neurological spectrum in dengue.A hospital-based prospective study was carried out in a tertiary-care hospital from December 2021 to August 2023, which included laboratory confirmed dengue positive cases with neurological involvement.We estimated DE incidence and analyzed clinical,laboratory and neuroimaging data.Out of 238 dengue patients,24 patients were finally enrolled with a mean age of 26.14±10.97 years and a male preponderance (58.33 %).The clinical spectrum included 7 cases of encephalopathy (29.17 %),5 encephalitis (20.83 %),4 myelitis (16.67 %),3 stroke (12.5 %),two Guillain-Barre syndrome(GBS) and Bell's palsy each (8.33 %) and one acute disseminated encephalomyelitis and hypokalemic paralysis each (4.17 %) with mortality in 1 patient (4.17%). Abnormal neuroimaging occurred in 14 cases (58.33 %) with double-doughnut sign (5 cases) and longitudinally extensive transverse myelitis (3 cases). In this study, neurological complications due to dengue were seen in 10.08%.Encephalopathy,encephalitis and myelitis were the commonest manifestations,followed by stroke and GBS.The entire neuro-axis can be affected by dengue infection.
