Insights

In Bangladeshi children with autism spectrum disorder (ASD), 44% showed epilepsy or abnormal electroencephalogram (EEG) findings. This suggests routine EEG screening for ASD patients, particularly those with severe symptoms.

Area of Science:

  • Neurology
  • Developmental Pediatrics
  • Clinical Neurophysiology

Background:

  • Autism spectrum disorder (ASD) is frequently comorbid with epilepsy.
  • The association between ASD, epilepsy, and electroencephalogram (EEG) abnormalities in the Bangladeshi population remains understudied.

Purpose of the Study:

  • To determine the incidence of epilepsy and/or abnormal EEG in Bangladeshi children diagnosed with ASD.
  • To explore the correlation between ASD severity and the presence of epilepsy or EEG abnormalities.

Main Methods:

  • Retrospective review of clinical history and EEG data.
  • Analysis of records from 18 children diagnosed with ASD.

Main Results:

  • 44% of children with ASD were diagnosed with epilepsy or had abnormal EEG findings.
  • Epilepsy or abnormal EEG occurred at significantly higher rates in children with more severe ASD.

Conclusions:

  • Neurological assessment, including EEG, should be considered routinely for children with ASD.
  • EEG screening is particularly recommended for children with more impaired ASD presentations to identify potential epilepsy or abnormalities.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
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...
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,...
