Insights

Transient mild reduction of consciousness in children during febrile illness is a distinct clinical group. This study found no significant differences in clinical, MRI, or EEG findings between children with or without delirious behavior.

Area of Science:

  • Pediatrics
  • Neurology

Background:

  • Febrile illness in children can cause transient, mild reductions in consciousness.
  • Understanding the characteristics of this condition is crucial for accurate diagnosis and management.

Purpose of the Study:

  • To investigate the clinical and neuroimaging features of children experiencing transient, mild consciousness reduction during febrile illness.
  • To compare patients with and without delirious behavior.

Main Methods:

  • Retrospective evaluation of 58 children admitted with mild consciousness reduction during febrile illness.
  • Comparison of clinical, brain MRI, and EEG findings between groups with and without delirious behavior.

Main Results:

  • 91% of patients exhibited delirious behavior; 9% did not.
  • No statistically significant differences in clinical, MRI, or EEG findings were observed between the groups.
  • Reversible white matter lesions were noted on MRI in some patients.
  • Transient EEG abnormalities were observed in both groups.

Conclusions:

  • Transient, mild consciousness reduction during febrile illness represents a unique clinical entity.
  • This condition includes children with and without delirious behavior.
  • Further research may elucidate specific underlying mechanisms.

Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Methods of reducing fever01:22

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Patterns of Fever

Before understanding the types and patterns of fever, it is essential to know its phases.
Types of Fever01:25

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:
Viral Meningitis01:18

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...

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
