Insights

This case report details a 3-year-old girl with epileptic encephalopathy and bilateral continuous spike-waves during slow wave sleep (BCSWS). This rare presentation occurred in a patient with megalencephalic leukoencephalopathy with subcortical cysts (MLC).

Area of Science:

  • Pediatric Neurology
  • Neuroscience
  • Genetics

Background:

  • Epileptic encephalopathies are severe neurological disorders characterized by frequent seizures and cognitive decline.
  • Bilateral continuous spike-waves during slow wave sleep (BCSWS) is an EEG pattern associated with specific epilepsy syndromes.
  • Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare inherited white matter disorder.

Observation:

  • A 3-year-old girl presented with focal motor seizures during sleep, progressing to myoclonic, atonic, and clonic seizures.
  • The patient subsequently developed bilateral continuous spike-waves during slow wave sleep (BCSWS).
  • Clinical, neuroimaging, and MRI findings were consistent with megalencephalic leukoencephalopathy with subcortical cysts (MLC).

Findings:

  • This is the first reported case of BCSWS in a patient diagnosed with leukodystrophy, specifically MLC.
  • The development of BCSWS suggests a potential link between MLC and specific epileptic encephalopathy phenotypes.

Implications:

  • Epileptic encephalopathy with BCSWS may contribute to neurological and neuropsychological deterioration in patients with MLC.
  • This case highlights the importance of considering diverse epilepsy presentations in white matter disorders.
  • Further research is warranted to understand the pathophysiology linking MLC and BCSWS.

Epilepsy ll: Types01:22

Epilepsy ll: Types

Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
Seizures: Classification01:13

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Seizures l: Introduction01:20

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,...
Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
Seizures ll: Types01:19

Seizures ll: Types

Seizures are sudden bursts of abnormal electrical discharge in the brain that interfere with normal function. They are commonly divided into three groups: focal seizures, generalized seizures, and other types that do not fit neatly into either category.Focal SeizuresFocal seizures begin in a single brain region. When awareness is preserved, they are called focal aware seizures and may cause sensations such as tingling, unusual smells, or flashing lights. When awareness is impaired, they are...
Encephalitis l: Introduction01:19

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...
