What Makes Autism Worse?

Understanding Autism Spectrum

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects several areas of mental development. It is characterized by a range of symptoms, including restricted/repetitive behaviors, language delay, social interaction/communication impairment, and co-occurring conditions such as motor abnormalities, gastrointestinal problems, epilepsy, intellectual disability, and sleep disorders. ASD typically manifests before the age of 3 years and is more common among boys than girls [1].

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) made changes to the diagnostic criteria for autism. It eliminated several sub-diagnostic categories and introduced the term "autism spectrum disorder" (ASD) to encompass both lower and higher functioning forms of autism. The diagnostic requirements were also simplified, with the focus on two main criteria: social communication/interaction and restricted and repetitive behaviors. Individuals must meet all the social communication/interaction criteria, including problems with reciprocating social or emotional interaction, severe difficulties maintaining relationships, and nonverbal communication problems. They must also meet two of the four restricted and repetitive behaviors criteria, including stereotyped or repetitive speech/motor movements, adherence to routines, restricted interests, and sensory reactivity.

The prevalence of ASD has been increasing over the years. The Center for Disease Control's Autism and Developmental Disabilities Monitoring Network estimated the prevalence to be 1 in 68 individuals in their latest survey. This increase is attributed to improved awareness and identification of milder forms of the disorder among clinicians. The earlier diagnosis and intervention can lead to better outcomes for individuals with ASD.

Understanding the core symptoms of autism is crucial in navigating the challenges faced by individuals with ASD and their caregivers. By recognizing and addressing these symptoms, appropriate interventions and support can be provided to enhance the quality of life for individuals on the autism spectrum.

Impact of Nutrition on Autism

Proper nutrition plays a significant role in the overall well-being of individuals with autism spectrum disorder (ASD). A healthy diet can help support their nutritional needs and potentially have a moderating effect on the progression of the disorder. However, it's important to note that there is a lack of conclusive scientific data regarding specific nutritional therapies as standard treatments for ASD. Let's explore some of the dietary challenges in autism and the effects of gluten-free and carbohydrate-restricted diets.

Dietary Challenges in Autism

Children with autism and ASD often face dietary challenges, which can have an impact on their health and well-being. They commonly exhibit picky eating behaviors and have a preference for energy-dense foods low in nutrition. This can lead to an unbalanced diet, deficiencies in essential nutrients, and potential health complications.

Furthermore, children with autism tend to reject fruits, vegetables, and whole grains, further exacerbating their unhealthy eating habits. It is crucial to address these challenges and ensure individuals with autism receive a diet that meets their nutritional requirements.

Effect of Gluten-Free and Carbohydrate-Restricted Diets

Research has shown that dietary interventions, such as a gluten-free diet and a carbohydrate-restricted diet, have demonstrated improvements in the behavior and cognitive skills of children with autism and ASD. However, it's important to note that these interventions may not be suitable or effective for every individual with autism.

A gluten-free diet involves the exclusion of gluten, a protein found in wheat, barley, and rye. Some studies suggest that eliminating gluten from the diet may lead to improvements in behavior and gastrointestinal symptoms in individuals with ASD. However, further research is needed to establish the efficacy and determine which individuals may benefit the most from this dietary approach.

A carbohydrate-restricted diet (also known as a ketogenic diet or KD) restricts the intake of carbohydrates while increasing the consumption of healthy fats. This type of diet has shown promising results in improving the behavior and cognitive skills of children with autism and ASD. However, it is important to note that the ketogenic diet should be implemented under the supervision of a healthcare professional due to its strict requirements and potential side effects.

It is crucial to approach dietary interventions for individuals with autism on an individualized basis, considering their specific needs and consulting with healthcare professionals, including dieticians. While some individuals may benefit from certain dietary modifications, there is no one-size-fits-all approach, and personalized nutritional strategies should be implemented.

By addressing the dietary challenges faced by individuals with autism and exploring potential interventions, we can strive to optimize their overall health and well-being.

Environmental Factors and Autism

Autism, a complex neurodevelopmental disorder, is influenced by a combination of genetic and environmental factors. While genetic predisposition plays a significant role, certain environmental factors can contribute to the risk of autism. In this section, we will explore prenatal and early childhood factors as well as the influence of air pollution and pesticides.

Prenatal and Early Childhood Factors

Numerous prenatal and early childhood factors have been suggested to be associated with an increased risk of autism. Maternal smoking, maternal infections during pregnancy, exposure to air pollution, and maternal use of certain medications are among the factors that have been studied.

Advanced parental age, particularly paternal age, has also been identified as an important risk factor for autism. Studies have shown a relationship between increased risk of autism and elevated paternal age, with a nearly two-fold greater risk for fathers aged 34-39 and more than two-fold greater risk for fathers older than 40. Maternal age, on the other hand, does not seem to have a significant correlation with autism risk.

Maternal physical diseases, such as metabolic syndrome, bleeding during pregnancy, and maternal infections (such as rubella, measles, mumps, chickenpox, influenza, herpes, pneumonia), have also been associated with an increased risk of autism in the child. These conditions can lead to hypoxia (deficiency of oxygen) in utero, which affects brain development and increases the risk of autism.

Maternal mental health, including mental illnesses and mental problems during pregnancy (such as depression, anxiety, and stress), is also associated with an increased risk of autism in the child. Maternal mental health issues can have epigenetic effects on the expression of fetal stress response genes and neural development genes, thereby increasing the risk of autism.

Maternal prenatal medication use, particularly psychiatric medication use, has been linked to an increased risk of autism in the child. Antiepileptic drugs, valproic acid, paracetamol (acetaminophen), and antidepressant medications are among the medications that have been associated with an increased risk.

Postnatal risk factors, such as low birth weight, postnatal jaundice, and postnatal infections (such as meningitis, mumps, varicella, fever, and ear infections), have also been found to be significant risk factors for autism. Low birth weight is associated with a two-fold increase in the risk of autism, and postnatal jaundice and infections are correlated with a higher risk [5].

Influence of Air Pollution and Pesticides

Exposure to air pollution, particularly during pregnancy and early childhood, has been studied for its potential association with an increased risk of autism. The impact of air pollution on autism risk is an active area of research, with studies suggesting a possible link between exposure to pollutants and the development of autism [4].

Prenatal and early childhood exposure to certain pesticides has also been investigated as a potential environmental risk factor for autism. The relationship between pesticide exposure and autism risk is complex and requires further research. However, studies have shown associations between pesticide exposure and an increased likelihood of autism spectrum disorder.

Understanding the impact of environmental factors on autism is crucial for developing strategies to mitigate risk and promote better outcomes for individuals with autism. Continued research in this field will aid in identifying preventive measures and interventions to support individuals with autism and their families.

Health Risks and Medications

As individuals with autism navigate their daily lives, certain health risks and medications can have an impact on their well-being. Understanding these factors is crucial for caregivers and individuals with autism to effectively manage their symptoms and overall health.

Weight Gain from Autism Medications

Medications used in the treatment of autism and Autism Spectrum Disorders (ASDs) can sometimes contribute to unintentional weight gain, particularly in children. Certain medications, such as antipsychotics and stimulants, have been associated with weight gain in children with autism.

It is essential for caregivers to closely monitor any changes in weight and consult with healthcare professionals to address this issue. Implementing a balanced and nutritious diet, along with regular exercise, can help manage weight gain and promote overall health.

Role of Vitamins and Minerals

Vitamins and minerals play a vital role in the overall well-being of individuals, including those with autism and ASD. Research suggests that vitamin and mineral supplements can improve metabolic functioning and reduce hyperactivity and tantrums in children with autism.

Consulting with a healthcare professional or a registered dietitian can help determine the specific needs of individuals with autism in terms of vitamins and minerals. These professionals can recommend appropriate supplements or dietary modifications to ensure that individuals with autism receive the necessary nutrients to support their overall health and well-being.

By being aware of the potential health risks associated with certain medications and understanding the role of vitamins and minerals, caregivers and individuals with autism can take proactive steps to address these factors and promote better health outcomes. Regular communication with healthcare professionals is essential to ensure that medication regimens and dietary interventions are tailored to the specific needs of each individual.

Sensory Sensitivities in Autism

Sensory sensitivities are a common experience for many individuals with autism. These sensitivities can have a significant impact on daily life and can vary from person to person. It's important to understand the impact of sensory sensitivities and explore coping mechanisms to support individuals on the autism spectrum.

Impact on Daily Life

Sensory sensitivities in autistic individuals can have a profound impact on their daily lives. Not all individuals with autism have sensory sensitivities, but for those who do, these sensitivities can manifest in various ways, with differing levels of sensitivity.

Autistic children and teenagers may experience oversensitivities or undersensitivities to sensory input. Oversensitivities may lead to aversion or distress when exposed to certain sensory experiences. This could result in behaviors such as seeking to avoid sensory input, crying, covering their ears or eyes, or displaying signs of restlessness and irritability.

On the other hand, undersensitivities may lead to seeking out sensory experiences, such as touching, tasting, or exploring different textures. Autistic individuals with undersensitivities might engage in repetitive behaviors (stimming) or exhibit a preference for intense sensory input.

These sensory sensitivities can impact an individual's daily routine, social interactions, and even their participation in various activities. It may necessitate accommodations and modifications to the environment, routines, and interactions to help individuals feel more comfortable and supported [6].

Coping Mechanisms for Sensory Challenges

Managing sensory sensitivities can be challenging for individuals with autism. However, over time, many individuals learn to develop coping mechanisms to better handle sensory challenges. These coping mechanisms can vary depending on the individual and their specific sensory sensitivities. Here are a few strategies that individuals with autism may find helpful:

It's important to understand that each individual with autism is unique, and what works for one person may not work for another. It may require patience, observation, and collaboration with professionals to discover effective coping mechanisms and strategies for managing sensory sensitivities.

By acknowledging and addressing sensory sensitivities, individuals with autism can lead more comfortable and fulfilling lives. Supporting them with appropriate coping mechanisms and accommodations can help minimize the impact of sensory challenges and create an environment that promotes their overall well-being and development.

Early Intervention for Autism

Early intervention plays a vital role in the management and development of individuals with autism spectrum disorder (ASD). It is widely recognized that early diagnosis and intervention can significantly improve behavior, skills, and language development, setting the foundation for a better quality of life [7]. While intervention can be beneficial at any age, starting early provides the opportunity for maximum impact.

Importance of Early Diagnosis

Obtaining an early diagnosis of autism is crucial for several reasons. Firstly, it allows for early access to appropriate support services and therapies that can address the specific needs of individuals with autism. Early diagnosis also enables families to better understand and navigate the challenges associated with autism, fostering a supportive environment at home and in the community.

Moreover, early diagnosis allows healthcare professionals to identify and monitor any co-occurring medical conditions that may be present in individuals with autism. This can help in the management of these conditions and ensure necessary interventions are implemented promptly.

Benefits of Behavioral Therapies

Behavioral therapies, such as Applied Behavior Analysis (ABA), have shown significant benefits in early intervention for autism. ABA is a treatment approach based on theories of learning and operant conditioning. It focuses on specific intervention targets and utilizes positive reinforcement, such as verbal praise, tokens, or edible rewards, to encourage desired behaviors [2].

One example of an early intensive ABA therapy model is the Early Start Denver Model. In a randomized, controlled trial involving 48 preschool-aged children with autism, this model demonstrated significant cognitive and adaptive behavior gains over a two-year period. The intervention provided by ABA therapists, coupled with positive reinforcement and repetition of learning trials, contributed to the positive outcomes observed.

The benefits of behavioral therapies extend beyond cognitive and adaptive behavior gains. They can also aid in enhancing social skills, communication abilities, and reducing challenging behaviors. These therapies are tailored to meet the unique needs of each individual, focusing on their strengths while addressing areas of difficulty.

By providing early intervention through behavioral therapies, individuals with autism can develop essential skills and abilities that will positively impact their daily lives and future prospects. It is important for parents, caregivers, and healthcare professionals to work together to identify and implement appropriate intervention strategies as early as possible.
