Understanding Autism and Seizures
Autism and seizures are two interconnected conditions that often coexist. Understanding the prevalence of seizures in individuals with autism as well as the complex relationship between the two is crucial for parents of children with autism.
Prevalence of Seizures in Autism
The prevalence of seizures in individuals with autism is significantly higher than in the general population. According to estimates, the prevalence of seizures in individuals with autism spectrum disorder (ASD) ranges from 5% to 46% [1]. A study found that 32.6% of children with autism had a history of seizures, with seizures being more prevalent in males compared to females.
Complex Relationship Between Autism and Seizures
The relationship between autism and seizures is complex and not yet fully understood. However, there is evidence to suggest that there may be shared genetic and neurological factors involved. Genetic abnormalities, such as copy number variants (CNVs) and single gene disorders, have been associated with both autism and seizures. More than 100 disease genes have been described as related to ASD, including SHANK3, CNTNAP2, and NLGN4X. These genetic abnormalities interfere with normal neurodevelopment and may contribute to the comorbidity between autism and epilepsy.
The risk of epilepsy is significantly higher in individuals with ASD compared to the general population, especially in individuals with intellectual disability [2]. Autism and epilepsy frequently co-occur and have overlapping genetic causes, including gene transcription regulation, cellular growth, synaptic channel function, and maintenance of synaptic structure. The association between autism and epilepsy is likely due to various factors, including the presence of intellectual disability, language abnormalities, ASD-specific symptom severity, motor issues, and genetic abnormalities. Developmental regression also plays a small role in the association between epilepsy and ASD.
Understanding the prevalence and relationship between autism and seizures is essential for parents of children with autism. This knowledge can help parents recognize and manage seizures effectively, leading to improved overall well-being and reduced impact on daily lives.
Types of Seizures in Autism
When it comes to seizures in individuals with autism, they can manifest in various forms. Understanding the different types of seizures can help parents recognize and respond appropriately to their child's needs. The three main types of seizures commonly associated with autism are generalized tonic-clonic seizures, absence seizures, and focal seizures.
Generalized Tonic-Clonic Seizures
Generalized tonic-clonic seizures, also known as grand mal seizures, are one of the most common seizure types in individuals with autism. These seizures typically involve a loss of consciousness, stiffening of the body (tonic phase), followed by rhythmic jerking movements (clonic phase). During this type of seizure, the child may experience convulsions and may exhibit uncontrolled movements of the limbs. It is essential for parents to create a safe environment during these seizures to prevent injury.
Absence Seizures
Absence seizures, also referred to as petit mal seizures, are characterized by a brief loss of awareness or consciousness. During an absence seizure, individuals may appear to be staring into space, unaware of their surroundings. These seizures are often mistaken for daydreaming or inattentiveness. The duration of absence seizures is typically short, lasting a few seconds to half a minute. However, they can occur multiple times throughout the day, potentially impacting a child's attention and learning abilities.
Focal Seizures
Focal seizures, previously known as partial seizures, originate in a specific area of the brain. These seizures can manifest with various symptoms, depending on the part of the brain affected. Focal seizures can be further classified into focal aware seizures (previously called simple partial seizures) and focal impaired awareness seizures (previously called complex partial seizures).
Understanding the various types of seizures in autism is crucial for parents to provide appropriate support and seek medical attention when necessary. It's important to remember that each child's experience with seizures may differ, and consulting with a healthcare professional is essential for accurate diagnosis and treatment.

Research has shown that there are genetic and neurological factors that contribute to the prevalence of seizures in individuals with autism. Let's explore these factors further.
Genetic and Neurological Factors
The relationship between autism and seizures is complex and not fully understood. However, there is evidence to suggest that there may be shared genetic and neurological factors involved. Studies have found overlapping genetic causes between autism spectrum disorder (ASD) and epilepsy, including gene transcription regulation, cellular growth, synaptic channel function, and maintenance of synaptic structure.
It is important to note that not all individuals with autism will experience seizures, but the prevalence of seizures in individuals with autism is estimated to be between 5% and 46%, which is significantly higher than the general population. A study found that 32.6% of children with autism had a history of seizures, with a higher prevalence in males compared to females.
Higher Risk in Individuals with Intellectual Disability
One of the significant risk factors for developing epilepsy in individuals with autism is overall cognitive function. The odds of having epilepsy decrease by 47% for every one standard deviation increase in IQ [6]. The risk of epilepsy is significantly higher in individuals with autism spectrum disorder (ASD) compared to the general population, with a higher risk in individuals with intellectual disability. The highest rate of epilepsy (46%) was observed in individuals with an IQ below 40.
It is worth noting that the association between autism and epilepsy is not solely due to intellectual disability. Other factors, such as language abnormalities, ASD-specific symptom severity, motor issues, and developmental regression, also play a role in this association. The presence of comorbidity between autism spectrum disorders (ASD) and epilepsy increases with age, particularly in adolescents with autism, and is more prevalent in autistic individuals with low intellectual function.
By understanding the risk factors and associations between autism and seizures, parents can be better equipped to manage and support their children. It is important to work closely with healthcare professionals to ensure proper diagnosis and effective management strategies to reduce the impact of seizures on the lives of individuals with autism.
