Autism: 5 Signs, Causes, Treatment, Coping Tips And FAQs

Autism, also known as Autism Spectrum Disorder (ASD), is a neurodevelopmental condition that affects how a person perceives the world and interacts with others. It is characterized by:

Challenges in social communication and interaction, such as difficulty understanding social cues, making eye contact, or forming relationships.
Restricted and repetitive behaviors, like hand-flapping, repeating words or phrases, or following specific routines rigidly.
Unique strengths and differences, including strong memory, attention to detail, or special interests in specific subjects.

ASD is called a “spectrum” because it presents differently in each individual, ranging from highly independent to needing significant support in daily life. Symptoms usually appear in early childhood, and while there is no cure, early intervention and supportive therapies can greatly improve outcomes.

What Is Autism Spectrum Disorder?

Autism is known as autism spectrum disorder (ASD), as it is a complex and multifaceted disorder that can impact individuals differently and to varying degrees. It stands recognized ¹ in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

Autism can occur in both children and adults, albeit with different sets of symptoms that mandate different diagnosis and treatment.

Some individuals with ASD may have relatively mild symptoms and be able to live independently, while others may have more severe symptoms and require significant support and assistance throughout their lives. This complexity and variability can make it challenging to address the long-term impact of autism.

Prevalence of autism

Autism can be detected as early as 6-18 months of age ². An experienced professional can make a reliable diagnosis of the early signs of autism by age 2. However, many children are not diagnosed until much later in life.

Research, nonetheless, estimates that, worldwide, 1 in 100 children has autism ³. Around 2.22% of adults, worldwide ⁴, also suffer from autism. The prevalence of autism has increased over the past few decades, which is partially attributed to changes in diagnostic criteria and increased awareness of the disorder.

Case Example

James, a 10-year-old boy, has been facing notable challenges in communication and social interaction over the past six months. He struggles to understand verbal and non-verbal cues, such as tone of voice and facial expressions, and often fails to interpret others’ intentions or messages accurately. In addition, James displays heightened sensitivity to sensory input—becoming overwhelmed by sounds, lights, textures, or touch—which frequently leads to intense emotional outbursts in overstimulating environments.

His parents have observed several atypical behaviors, including avoidance of eye contact, lack of response to greetings, and minimal interest in engaging with peers or family members. James also shows a preference for routine and sameness. He persistently plays with the same toy—even when it is broken—and insists on wearing the same color clothing daily, regardless of cleanliness. At school, he finds it difficult to follow instructions, struggles with classroom transitions, and is unable to form friendships with his classmates.

Case Analysis

James presents with core features characteristic of Autism Spectrum Disorder (ASD). These include marked difficulties in reciprocal communication and social interaction, heightened sensitivity to sensory stimuli, restricted and repetitive patterns of behavior, and emotional regulation challenges. His rigidity in interests, insistence on sameness, and limited ability to form social connections further support the presence of significant symptoms aligned with ASD. Early diagnosis and appropriate interventions will be crucial in supporting James’s development and enhancing his quality of life.

Autism Symptoms

Spectrum Disorder (ASD)

The symptoms of autism in adults and children differ. However, certain symptoms ⁵ are central to the disorder, such as:

Difficulties with social interaction and communication, such as difficulty with eye contact, facial expressions, and body language
Repetitive behaviors or interests, such as lining up toys, repeating words or phrases, or having a strong attachment to certain objects
Difficulty with changes in routine or environment
Sensory sensitivities, such as being overly sensitive or under-sensitive to certain sounds, textures, or smells
Difficulty with motor skills, such as delays in crawling, walking, or running

Symptoms Of Autism In Children vs Adults

Types Of Autism Spectrum Disorder (ASD)

The different types ⁶ of ASD are classified based on their symptoms and characteristics. These include:

1. Autistic disorder (Classic autism)

This is the most well-known and severe form of ASD. It is characterized by significant impairments in communication, social interaction, and behavior, as well as the presence of stereotyped or repetitive behaviors.

2. Asperger’s syndrome (AS)

However, people with AS are said to have “high-functioning autism”, because of which they do not have the severe language or cognitive impairments that characterize people with autism.

3. Pervasive developmental disorder – not otherwise specified (PDD-NOS)

This type of ASD is used to describe individuals who have significant impairments in social interaction and communication, but who do not meet the full criteria for classic autism or Asperger’s syndrome.

4. Rett syndrome

This is a rare genetic disorder that affects females. It is characterized by a loss of cognitive and social skills, as well as the presence of stereotyped hand movements.

5. Childhood disintegrative disorder (CDD)

This is a rare type of ASD in which children appear to develop normally for the first few years of life, but then experience a significant loss of skills and abilities in multiple areas, including social interaction, communication, and behavior.

Autism And Mental Health

Autism and mental health are intricately connected ⁷, with one often influencing the other. Individuals with ASD can experience a range of mental health challenges, including anxiety, depression, and ADHD. Conversely, the symptoms and impairments associated with ASD can also impact mental health and well-being.

The symptoms and impairments associated with ASD can also impact mental health and well-being, including social isolation, sensory overload, difficulty with emotional regulation, and difficulty with transitions.

Individuals with ASD are at a higher risk for developing co-occurring mental health conditions ⁸ than the general population. These mental health disorders include:

Depression [Read more]
Attention Deficit Hyperactivity Disorder (ADHD) [Read more]
Obsessive-Compulsive Disorder (OCD) [Read more]

What Causes Autism?

Research ⁹ attributes the common causes of autism to the following factors:

1. Genetics

Autism is believed to have a strong genetic component ¹⁰, with research indicating that the condition may be inherited from family members who have a similar condition. Changes in gene expression can also be a prominent risk factor for ASD.

2. Brain development

Autism may be linked to differences or disruptions in the development of the brain, specifically in the areas of communication, social interaction, and sensory processing (like amygdala and insula).

3. Environmental factors

Certain environmental factors, such as exposure to toxins during pregnancy or complications during childbirth, may increase the risk of developing autism spectrum disorder. Specifically, prenatal and perinatal factors ¹¹ (such as maternal stress and addiction to substances or complications during childbirth) constitute predominant risk factors in its development.

4. Neurological differences

Individuals with autism may have neurological differences (linked to brain volume and symmetry) in the way their brains process information. This can affect their social and communication skills.

5. Other medical conditions

ASD has been linked to other medical conditions, such as epilepsy, gastrointestinal disorders, and immune system disorders. While these conditions are not direct causes, they may contribute to the development or severity of symptoms.

How Is Autism Diagnosed?

Early diagnosis ¹² and intervention are crucial for improving treatment outcomes for individuals with ASD. The diagnosis of autism spectrum disorder (ASD) involves a comprehensive evaluation by a healthcare professional specializing in autism treatment.

It includes screening for developmental delays, evaluation of communication skills, social interaction, and behavior. Diagnostic criteria for ASD ¹³ are outlined in DSM-5 and an individual must meet specific criteria related to social communication and interaction and restricted, repetitive patterns of behavior.

There are also various diagnostic tools available for ASD ¹⁴, including the Autism Diagnostic Interview-Revised (ADI-R), the Autism Diagnostic Observation Schedule (ADOS), and the Childhood Autism Rating Scale (CARS).

These tools can help to provide a more standardized and objective assessment of an individual’s symptoms and behaviors and can assist in making an accurate diagnosis of ASD.

Autism Treatment

Autism treatment methods typically involve a combination of therapies and interventions ¹⁵ tailored to the individual’s specific needs. These include:

1. Behavioral therapies

Behavioral therapies, such as Applied Behavior Analysis (ABA), can help individuals with ASD improve their communication, social interaction, and behavior.

2. Speech and language therapy

Speech and language therapy can help individuals with ASD improve their communication skills and ability to express themselves.

3. Occupational therapy

Occupational therapy can help individuals with ASD develop the skills needed for daily living, such as dressing, eating, and grooming.

4. Sensory integration therapy

Sensory integration therapy can help individuals with ASD improve their ability to process and respond to sensory input.

5. Medication

Medication ¹⁶ may be used to treat co-occurring conditions, such as anxiety or ADHD, that can often accompany ASD.
