Insights

Acute Infantile Encephalopathy Predominantly Affecting the Frontal Lobes (AIEF) can cause severe cognitive decline. This study presents two pediatric cases of AIEF, highlighting its frontal lobe impact and association with Influenza B.

Area of Science:

  • Neurology
  • Pediatrics
  • Infectious Diseases

Background:

  • Acute Infantile Encephalopathy Predominantly Affecting the Frontal Lobes (AIEF) is an emerging neurological condition.
  • Understanding AIEF is crucial for early diagnosis and intervention in affected children.

Observation:

  • Two pediatric cases of AIEF with bifrontal involvement during acute febrile encephalopathy are detailed.
  • Case 1: A 1-year-old boy with hyperpyrexia, seizures, and Influenza B infection showed bilateral frontal lobe involvement and subsequent cognitive decline.
  • Case 2: A 6-year-old boy presented with frontal lobe dysfunction after status epilepticus, with imaging revealing superior frontal lesions.

Findings:

  • Both cases demonstrate significant bilateral frontal lobe pathology in acute encephalopathy.
  • Influenza B infection was identified as a potential trigger in one of the presented AIEF cases.
  • Neuroimaging confirmed bifrontal involvement, including gyral swelling in one patient.

Implications:

  • These findings contribute to the limited literature on AIEF, emphasizing its distinct frontal lobe predilection.
  • Early recognition of AIEF is vital for managing cognitive and behavioral sequelae in children.
  • Further research into AIEF pathogenesis and long-term outcomes is warranted.

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Arboviral Encephalitis01:25

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
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...
