Insights

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is increasingly recognized in children. Prompt treatment with intravenous immunoglobulin is crucial for patients presenting with subtle neurological symptoms.

Area of Science:

  • Neurology
  • Immunology
  • Pediatrics

Background:

  • Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis diagnosis has expanded with antibody identification.
  • The condition is increasingly recognized in pediatric populations.

Observation:

  • Younger patients with anti-NMDAR encephalitis are less likely to present with tumors.
  • Common early symptoms include behavioral changes, speech problems, seizures, and abnormal movements.
  • A case presented with subtle, non-specific symptoms.

Findings:

  • The presented case demonstrated a prompt response to intravenous immunoglobulin therapy.
  • This highlights the effectiveness of immunotherapy in specific neurological conditions.

Implications:

  • Considering anti-NMDAR encephalitis is important for unexplained neurological conditions in children.
  • Early diagnosis and treatment can lead to better patient outcomes.
  • This expands the understanding of the clinical spectrum of anti-NMDAR encephalitis.

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 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...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
