Mania and Antimanic Drugs: Overview

Mania and Antimanic Drugs: Overview

Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a...

Arboviral Encephalitis

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Viral Meningitis

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Summary

Dengue fever, a significant health issue in Southeast Asia and India, can rarely cause acute psychosis or mania. This case report details a 21-year-old male who developed mania following a Dengue infection.

Neurology
Infectious Diseases
Psychiatry

Background:

Dengue fever is a major public health concern in Southeast Asia, with increasing outbreaks in India.
Neurological complications of Dengue, such as encephalitis and encephalopathy, are increasingly reported.
A link between Dengue fever and acute psychosis or mania has not been previously documented in medical literature.

Purpose of the Study:

To report a rare case of acute mania following Dengue infection.
To highlight the potential for Dengue fever to cause psychiatric manifestations.

Main Methods:

Case report of a 21-year-old male presenting with symptoms of mania after Dengue infection.
Clinical evaluation and diagnosis of Dengue fever and subsequent manic episode.

Main Results:

The patient developed classical mania after recovering from Dengue fever.
This represents a novel association between Dengue infection and acute manic episode.

Conclusions:

Dengue fever may be an underrecognized cause of acute psychosis and mania.
Further research is warranted to explore the neurobiological mechanisms linking Dengue virus infection and psychiatric disturbances.
