Objective: This case reported highlighted psychotic disorder due to dengue fever
is rare. Hence we describe a case which clearly presented with psychotic
symptoms during the illness.
Methods: We reported a case of psychotic disorder
due to dengue fever who presented with psychotic symptoms of auditory and
visual hallucination, and persecutory delusion, which had significant temporal
correlation with dengue fever symptoms. There were no neurological deficits
noted, no altered sensorium and cognitive impairment during the episode. He
has no past and family history of mental illness and there was no evidence of
encephalitis and metabolic disturbances.
Results: Our case suggests that
prominent psychotic symptoms can occur during an episode of dengue fever,
which remitted when one recovering from dengue fever.
Conclusion: We
demonstrated that patients who presented with the acute onset of psychosis
accompanied by symptoms of viral fever should be screened for dengue fever,
particularly if the person lived in or visited the area where dengue fever is
endemic.
