What is ASD?

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects how a person interacts, communicates, and behaves. It is a spectrum disorder, which means that individuals with ASD can experience a range of symptoms, from mild to severe. ASD is typically diagnosed in early childhood, but some individuals may not receive a diagnosis until later in life.

Although ASD varies significantly in character and severity, it occurs in all ethnic and socioeconomic groups and affects every age group. Experts estimate that six children out of every 1,000 will have an ASD. Males are four times more likely to have an ASD than females.

What are the symptoms of ASD?

Difficulty in understanding social cues and norms, difficulty in maintaining eye contact, and a lack of interest in socializing or making friends.

Difficulty in understanding and using language, delayed speech development, and a tendency to repeat words or phrases.

Engaging in repetitive movements or actions, having a strong attachment to routines and rituals, and having narrow and intense interests.

Over- or under-sensitivity to sensory stimuli, such as light, sound, touch, taste, or smell.

ASD can be associated with differences in cognitive abilities, including strengths in visual-spatial skills and attention to detail, and challenges with abstract thinking, problem-solving, and flexible thinking.

It is important to note that individuals with ASD can present with a wide range of symptoms and levels of severity, and that some individuals may have strengths in areas that are not typically associated with ASD. It is also common for individuals with ASD to have co-occurring conditions such as anxiety, ADHD, and sleep disorders

What Causes ASD ?

The exact cause of Autism Spectrum Disorder (ASD) is not yet fully understood, but research has identified both genetic and environmental factors that may contribute to the development of the condition. According to a review published in the journal Nature in 2019, some of the key findings regarding the causes of ASD include:

Research has identified hundreds of genetic mutations that are associated with an increased risk of ASD. Many of these mutations are related to the development and function of the brain and nervous system. However, it is important to note that no single gene has been found to cause ASD in all cases.

Environmental factors, such as exposure to toxins, infections, and maternal stress during pregnancy, have been identified as potential contributors to the development of ASD. However, more research is needed to better understand the role of environmental factors in ASD.

Abnormalities in brain development have been identified in individuals with ASD, including differences in the size and connectivity of certain brain regions. These differences may affect the way that individuals with ASD process information and interact with others.

Some research has suggested that immune dysfunction may play a role in the development of ASD. For example, studies have found differences in the immune system functioning of individuals with ASD compared to typically developing individuals.

It is important to note that ASD is a complex and heterogeneous condition, and there is likely no single cause that applies to all cases. Instead, it is likely that ASD results from a combination of genetic and environmental factors that interact in complex ways.

Medical problems associated

Autism Spectrum Disorder (ASD) is diagnosed based on persistent deficits in social communication and social interaction, as well as restricted and repetitive patterns of behavior, interests, or activities. These deficits can manifest in various ways, including:

 Difficulty with social-emotional reciprocity, such as a lack of interest in social interaction or difficulty initiating or responding to social cues.

 Challenges with nonverbal communicative behaviors, such as making eye contact, using gestures, or understanding facial expressions.

 Difficulty developing, maintaining, and understanding relationships with others.

 Engaging in stereotyped or repetitive behaviors, such as repetitive motor movements, using objects in a specific way, or repeating certain phrases.

 Insistence on sameness, such as needing to follow the same routine or engage in the same activities in a specific order.

 Highly restricted, fixated interests that are abnormal in intensity or focus, such as an intense interest in a particular topic or object.

 Hyper- or hypo-reactivity to sensory input, such as being overly sensitive to certain textures or sounds, or having an unusual interest in sensory aspects of the environment.

Early Interventions for ASD ?

Early intervention is crucial for individuals with Autism Spectrum Disorder (ASD), as it can significantly improve outcomes and quality of life. Here are some of the early interventions for ASD based on Stanford's research:

ABA is a structured and individualized approach that focuses on improving specific skills, such as communication and social interaction, by breaking them down into smaller, manageable steps.

Speech therapy can help individuals with ASD develop language skills and improve their ability to communicate effectively with others.

Occupational therapy focuses on helping individuals with ASD develop skills related to daily living activities, such as dressing, eating, and grooming, as well as skills related to play, social interaction, and sensory processing. Occupational therapists work with individuals with ASD to develop personalized treatment plans that address their specific needs and goals.

Social skills training can help individuals with ASD learn how to interact with others in a socially appropriate manner, including developing skills such as taking turns and sharing.

Sensory integration therapy focuses on helping individuals with ASD who are sensitive to sensory stimuli, by developing coping strategies to manage their sensory experiences.

Parent-mediated intervention involves training parents to provide targeted interventions at home to support their child's development and improve their social and communication skills.

Prenatal Screening and Diagnosis

ASD can vary in severity and symptoms, which can make it difficult to recognize, especially in mildly affected children or when it is masked by other disabilities. However, there are certain early indicators that should prompt evaluation by an expert. These include:

 No babbling or pointing by age 1

 No single words by 16 months or two-word phrases by age 2

 No response to name

 Loss of language or social skills

 Poor eye contact

 Excessive lining up of toys or objects

 No smiling or social responsiveness

 Difficulty making friends with peers

 Difficulty initiating or sustaining conversations with others

 Impairment or absence of imaginative and social play

 Stereotyped, repetitive, or unusual use of language

 Restricted patterns of interest that are abnormal in intensity or focus

 Preoccupation with certain objects or subjects

 Inflexible adherence to specific routines or rituals

It's important to note that these indicators do not necessarily indicate that a child has ASD, but rather that further evaluation by an expert is necessary. Early diagnosis and intervention can greatly improve outcomes for individuals with ASD, so it's important to seek professional evaluation if there are concerns about a child's development.

Getting Help with ASD

ASD is diagnosed through a comprehensive evaluation that requires a multidisciplinary team, including a psychologist, neurologist, psychiatrist, speech therapist, and other professionals who diagnose children with ASDs. Screening instruments are used to gather information about a child's development and behaviour, and if they indicate the possibility of an ASD, a more comprehensive evaluation is usually indicated. Children with some symptoms of an ASD but not enough to be diagnosed with classical autism are often diagnosed with PDD-NOS, while those with autistic behaviors but well-developed language skills are often diagnosed with Asperger syndrome.

At Braintree Healthcare, we provide comprehensive assessments for children suspected of having ASD, including the use of screening instruments and a multidisciplinary team approach. Our team of experienced professionals works together to evaluate each child's unique needs and provide recommendations for appropriate interventions, therapies, and support services. We also offer ongoing support and guidance for families throughout the diagnostic process and beyond.
