Insights

This case report highlights a rare instance of West syndrome in an infant with lissencephaly. Corpus callosotomy effectively reduced intractable seizures and improved developmental trajectory.

Area of Science:

  • Pediatric Neurology
  • Epileptology
  • Neuroscience

Background:

  • West syndrome, a severe infant epilepsy, is often associated with underlying brain abnormalities.
  • Lissencephaly, a malformation of cortical development, presents significant neurological challenges.
  • Intractable seizures in infants necessitate exploration of advanced therapeutic options.

Observation:

  • An 11-month-old infant with lissencephaly presented with medically intractable West syndrome and generalized tonic seizures.
  • Electroencephalography (EEG) revealed hypsarrhythmia and focal epileptiform discharges.
  • Magnetic Resonance Imaging (MRI) confirmed severe bilateral lissencephaly.

Findings:

  • Total callosotomy was performed at 11 months of age.
  • Postoperatively, there was a prominent decrease in seizure frequency.
  • The infant demonstrated resumed developmental progression after the surgical intervention.

Implications:

  • This case suggests the corpus callosum's significant role in certain forms of symptomatic West syndrome.
  • Corpus callosotomy emerges as a viable surgical consideration for carefully selected cases of symptomatic West syndrome.
  • Timing of surgical intervention is a critical factor in managing intractable infant epilepsies associated with brain malformations.

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,...
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:

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 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...
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...

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
