Timing of Autism Regression: Key Factors to Know
Understanding Autism Regression
Autism regression, also known as late-onset autism, refers to a period of typical development followed by a loss of previously acquired skills or a noticeable decline in social and communication abilities. This regression can occur at different stages of a child's life, with early-onset regression and late regression being two distinct patterns.
Early-Onset Regression
Early-onset regression typically occurs between the ages of 15 and 30 months, with an average diagnosis age of around 19 months. During this period, a child who has been developing typically may suddenly experience a loss of language and social skills, as well as a decline in cognitive abilities. This regression can be sudden or gradual and may be accompanied by behavioral changes.
It is estimated that up to 50 percent of all autism diagnoses are considered to be of the regressive type, where a child seems to develop normally but then suddenly loses some of their acquired skills. Early-onset regression can be a challenging and distressing experience for both the child and their parents.
Late Regression
Late regression, on the other hand, occurs later in a child's life, typically around adolescence. According to 2021 research, the mean onset of late regression is around 13 years old. Late regression is less common than early-onset regression but can still have a significant impact on the individual and their family.
The exact causes of autism regression are still not fully understood. However, research suggests that both genetic and environmental factors play a role in the development of regression. Immune dysfunction and changes in the brain are also believed to contribute to the regression process. Further study is needed to gain a deeper understanding of the underlying mechanisms.
Recognizing the signs of regression is crucial for early intervention and appropriate support. Parents should be vigilant for subtle symptoms before regression, such as a loss of interest in social interactions or speech regression. Behavioral changes, such as increased irritability or repetitive behaviors, may also indicate regression [3].
Understanding the different patterns of autism regression, such as early-onset and late regression, can help parents and caregivers navigate the challenges associated with these developmental changes. Early intervention strategies and therapies, such as speech therapy and behavioral interventions, can play a vital role in supporting individuals with regressive autism.

Duration and Impact of Regression
When it comes to autism regression, understanding the duration and impact is essential for parents of children with autism. Regression refers to the loss of previously acquired skills, such as language, social interaction, or play abilities. In this section, we will explore both the lifelong effects and short-term regression commonly observed in individuals with autism.
Lifelong Effects
Some instances of developmental regression, particularly those seen in early onset autism spectrum disorder (ASD), can last a lifetime. Children who experience regression at a young age may struggle to regain the lost skills, even with intervention and therapy. It is important to provide ongoing support and interventions to help individuals with lifelong regression in order to maximize their potential and quality of life.
Short-Term Regression
In other cases, regression may be temporary, lasting for days or weeks. The duration of short-term regression can vary depending on the individual and the specific skills affected. While the regression may be temporary, it is still important to address and support the child during this challenging period.
It is worth noting that language regression is one of the most frequently reported aspects of regression in children with autism, often accompanied by a loss of nonverbal communication skills and social interaction abilities. According to studies, around one-third of young children with ASD experience a loss of skills during the preschool period, with language being the most commonly affected area. The average age of regression is reported to be around 20 months, with slight delays in development often preceding the loss of skills.
Recognizing the signs of regression and seeking early intervention and therapy are essential in supporting individuals with autism. While the impact of regression can be challenging, with appropriate interventions and support, individuals with autism can continue to learn and develop new skills. The focus should be on individualized strategies and therapies that target the specific needs of each child.

Patterns of Regression
When it comes to autism regression, there are certain patterns that can help parents understand and recognize the signs. Two key aspects of regression are the loss of established skills and the variability in regression duration.
Loss of Established Skills
Regressive autism, also known as late-onset autism, involves a period of typical development followed by a loss of previously acquired skills or a noticeable decline in social and communication abilities. This regression usually occurs between 15 and 30 months of age and can be sudden or gradual.
Language loss is one of the most commonly reported aspects of regression by parents. Children who were talkative and then stopped talking may also experience a loss in nonverbal communication skills, such as imitation, direct eye contact, and responding to their name. It is important to note that not all children with autism experience regression, as autism can manifest in various ways.
Variability in Regression Duration
The timing of regression in Autism Spectrum Disorder Regression (ASD-R) can vary significantly. It typically occurs within the second and third years of life, with the average reported age of regression being around 20 months. However, regression can happen as early as 15 months or as late as 81 months.
The duration of regression can also vary from child to child. Some children may experience a temporary regression, while others may have a long-lasting impact. Understanding that regression can have different durations is essential for parents seeking to support their child's development and intervention strategies.
By being aware of the patterns of regression, parents can be more prepared to recognize the signs and seek appropriate intervention and therapy. If you suspect that your child may be experiencing regression, it is important to consult with healthcare professionals and specialists who can provide guidance and support.
Factors Influencing Regression
Regression in autism is a complex phenomenon, and several factors can play a role in its occurrence. Understanding these factors can provide valuable insights into the development of autistic behavior in children.
Genetic and Environmental Factors
Studies suggest that a regressive structure caused by a combination of genetic and environmental factors can contribute to the development of autistic behavior in children. Research indicates that certain genes may predispose individuals to a higher risk of experiencing regression [4]. However, the exact genetic mechanisms involved in regression are still being investigated.
Environmental factors, such as prenatal and early-life exposures, can also contribute to the onset of regression in autism. For example, a study led by Betty Diamond suggested that autism may be caused by anti-brain antibodies penetrating the immature blood-brain barrier of a developing fetus in the womb, leading to brain damage and resulting in autism or developmental delays at birth.
Immune Dysfunction and Brain Changes
Researchers have found evidence linking autism regression with immune dysfunction and brain changes. A study led by Dr. Paul Ashwood of the University of California, Davis, revealed a potential association between regression and elevated levels of immune cells called dendritic cells in autistic children. This immune dysfunction, along with brain changes, gastrointestinal distress, and severe repetitive behaviors, may contribute to the manifestation of regressive autism.
The interplay between immune dysfunction and brain changes in regression requires further investigation to fully understand their role in the development of autistic behavior. Ongoing research aims to uncover the underlying mechanisms and potential therapeutic interventions.
By considering the genetic and environmental factors, as well as immune dysfunction and brain changes, researchers and clinicians can gain a deeper understanding of the factors influencing regression in autism. This knowledge contributes to the development of effective intervention strategies and therapies for individuals with regressive autism.
Recognizing Regression Signs
Recognizing the signs of autism regression is important for early intervention and support. Regression refers to the loss of previously acquired skills or a decline in developmental progress. In the case of autism, regression typically involves a loss of social and communication skills. Understanding the subtle symptoms that may precede regression and being aware of behavioral changes can help parents identify and address potential concerns.
Subtle Symptoms Before Regression
Recent research suggests that children who are diagnosed with regressive autism may have subtle symptoms even before the regression takes place. Studies have shown that between the ages of 1 and 2, many children who later receive an autism diagnosis experience declines or changes in their developmental progress, with some of these declines being subtle [3].
For example, a study conducted at the University of California Davis found that children who would later be diagnosed with autism showed a decline in early social skills between 6 and 12 months of age, such as gazing at faces, smiling, and making eye contact. These subtle early symptoms may serve as potential indicators of future regression and warrant further evaluation by healthcare professionals.
Behavioral Changes
One of the hallmark signs of autism regression is a noticeable change in behavior. Children who experience regression may exhibit a loss of previously acquired skills, particularly in the areas of language and communication. Around 77 percent of children who lost language skills also experienced a decline in communication skills.
Some children who were previously talkative may stop talking altogether, while others may demonstrate a pattern of developing and then losing nonverbal communication skills, such as imitation, direct eye contact, and responding to their name. These behavioral changes are often observed between the ages of 15 and 30 months, with many children showing slight developmental delays before experiencing a loss of words [4].
It is crucial for parents to pay attention to any significant behavioral changes in their child's development and seek professional advice if they suspect regression or other signs of autism. Early recognition and intervention can make a significant difference in the long-term outcomes for individuals with autism.
Intervention and Therapy
When it comes to addressing autism regression, early intervention and therapy play a crucial role in supporting children with autism. Two key approaches that have shown promise in helping individuals with regressive autism are steroid therapy and early intervention strategies.
Steroid Therapy Benefits
Steroid therapy, which may involve medications like prednisolone, has shown improvements in receptive and expressive language skills in children with regressive autism. Research suggests that these medications can assist in the development of communication skills. However, it is important to consult with physicians before considering steroid therapy due to potential side effects.
Early Intervention Strategies
In many cases, children diagnosed with regressive autism who receive early and intensive therapy can acquire the necessary tools to improve their skills and function independently. Early intervention strategies are tailored to meet the unique needs of children with autism and typically involve a combination of therapies such as Applied Behavior Analysis (ABA), speech therapy, occupational therapy, and social skills training.
The goal of early intervention is to address developmental delays and challenges associated with autism as early as possible. The earlier therapeutic interventions begin, the greater the potential for positive outcomes. Through consistent and structured therapy, children with regressive autism can work on various areas, including communication, social interaction, cognitive skills, and adaptive behaviors. These interventions are designed to promote individualized growth and help children reach their full potential [1].
By utilizing a combination of therapies and interventions, children with regressive autism can make significant progress in their development. It is important to note that the progress and outcomes may vary depending on the severity of the condition and individual factors. Regular evaluations and adjustments to the therapy plan are essential to ensure that the child's specific needs are being met.
Early recognition and intervention are key in supporting individuals with autism. The sooner autism regression is identified and appropriate interventions are implemented, the better the chances for improved outcomes and quality of life. Ongoing research continues to shed light on the underlying causes of regressive autism, such as immune dysfunction and brain changes, and this knowledge informs the development of effective intervention strategies.
Remember, each child with autism is unique, and an individualized approach to therapy and intervention is essential. With appropriate support and therapeutic interventions, children with regressive autism can make progress and achieve their full potential.
