Autism Spectrum Disorder: Types, Symptoms, Causes & Treatment

According to numerous research studies examining the diverse manifestations of autism spectrum disorder (ASD), several potential subtypes are present based on symptomatic presentations encountered by individuals. Although these studies indicate the existence of these subtypes, further comprehensive research will be necessary to confirm and clarify their validity.

For instance, a study postulated a potential subtype of ASD distinguished by heightened language impairment and pronounced social withdrawal. Similarly, another survey disclosed the possibility of another ASD subtype characterized by a predisposition towards repetitive behaviors and circumscribed interests. However, it remains imperative to underscore that these postulated subtypes are not mutually exclusive, as individuals with ASD might concurrently exhibit manifestations aligned with multiple subtypes.

A thorough understanding of the complexities associated with autism spectrum disorders requires consulting with medical professionals, particularly those who specialize in such conditions. By collaborating with such experts, one can better understand the specific symptoms one is experiencing. Subsequently, this knowledgeable insight can serve as a foundation for formulating a tailored treatment regimen according to the individual's distinct requirements.

Moreover, ASD can be elucidated through various lenses, including:

• Severity gradient: The ASD is categorized into three levels of severity—mild, moderate, and severe, which provides a framework to gauge the degree of support an individual necessitates in their day-to-day functioning.
• Dominant impaired domains: ASD can influence an individual's communication and social interaction and display restricted and repetitive behaviors at varying levels. Some individuals encounter more pronounced challenges in one domain compared to others.
• Concomitant features: ASD can often intersect with other conditions, such as intellectual disabilities, anxiety disorders, and attention deficit hyperactivity disorder (ADHD), highlighting the intricate interplay of neurodevelopmental factors.

The doctors usually bucket the symptoms and signs of Autism into three groups: 

Communication difficulties:

Children with ASD may struggle to communicate in various ways, including understanding language, expressing themselves verbally, and using nonverbal communication. According to a study published in "Pediatrics," children with ASD often develop speech and language skills later than those without ASD. According to another study, children with ASD have difficulty understanding and using language effectively. Children with ASD may encounter:

• Delayed speech or language development: Some children with ASD might start talking later or face issues with grammar and pronunciation.
• Understanding language: People with ASD can struggle to grasp language, even simple words.
• Expressing themselves verbally: Some children with ASD may experience challenges using words to convey their thoughts.
• Nonverbal Communication Challenges: Understanding and using nonverbal cues, like expressions, can be complex.

Challenges in social interaction:

Those with Autism might find it challenging to make friends, read social cues, and converse. According to one study published in the "Autism" journal, children with ASD struggle with social reciprocity and eye contact. Similarly, another "Developmental Psychology" study emphasized the difficulty of forming and maintaining friendships. People with ASD may find social challenges, such as:

• Difficulties with social reciprocity: Taking turns and sharing interests can be challenging.
• Difficulties with eye contact: Making eye contact may be problematic or excessive.
• Difficulties with social cues: Grasping body language and facial expressions can be difficult.
• Challenges with making friends: Building and keeping friendships can be challenging.
• Preference for solitary activities: Some children with ASD might prefer to play alone or engage in solitary activities.

Restricted and repetitive behaviors:

Children with ASD often exhibit repetitive behaviors and a need for routine. A study in the "Journal of Autism and Developmental Disorders" stated that people with ASD have a strong tendency for sameness. According to another study, children with ASD tend to have repetitive actions, restricted interests, and sensory sensitivities. They may have:

• Insistence on sameness: The person can experience a strong need for consistency and predictability in their surroundings.
• Repetitive movements: Engaging in repeated actions like hand-flapping or rocking.
• Restricted interests: Intense focus on specific topics or activities.
• Sensory sensitivities: Individuals may be sensitive to sensory stimuli like light, sound, touch, taste, or smell.

Autism Spectrum Disorder (ASD) may occur due to genetic and environmental influences. A comprehensive 2017 review published in the "Annual Review of Public Health" points out the mutual impact of these factors and underscores the need for further exploration to decipher their role in ASD's manifestation. A detailed investigation of these factors sheds light on the complexity of ASD's origins and development:

Genetic Factors:

Genetic factors play an important role in ASD's emergence, and research indicates that specific genetic variations are associated with a greater risk of developing ASD. In 2017, a study in the journal "Nature" identified these genetic mutations, finding that rare genetic variants are more prevalent in individuals with autism spectrum disorders.

Environmental factors:

In addition to genetic susceptibility, environmental inputs, such as prenatal exposures and early-life encounters, also contribute to ASD. According to a study published in "Environmental Health Perspectives," prenatal air pollution exposure is associated with autism spectrum disorders. The research also unveiled a connection between specific air pollutants during pregnancy and an elevated risk of ASD diagnosis in children.

Brain development and connectivity:

Children with ASD may have noteworthy deviations in brain development and connectivity. These variations can influence the behavioral and cognitive characteristics of ASD in brain structure and neural connections. According to a 2014 study published in "JAMA Psychiatry," used neuroimaging to contrast brain connectivity patterns between individuals with and without autism spectrum disorder. It revealed distinct patterns of brain connectivity related to social communication and cognitive functions.

Maternal factors:

Pregnancy-related maternal elements, encompassing immune responses and nutritional status, are subjects of inquiry for their potential ASD influence. A 2016 "Molecular Psychiatry" study scrutinized maternal immune responses and their correlation with ASD risk. It revealed a link between maternal immune activation during pregnancy and heightened ASD risk in offspring.

There is no definitive way to prevent autism spectrum disorder (ASD) development in children. But, there are a few things that parents can do to reduce their child's risk of developing ASD, such as:

1. Early intervention and treatment: Timely identification and intervention can significantly impact the lives of individuals with ASD. Recognizing developmental delays or signs of ASD early on allows for implementing appropriate therapies that address communication, social interaction, and behavior challenges.

2. Prenatal care: To ensure the mother and her developing fetus are in the best health during pregnancy, comprehensive prenatal care, regular medical check-ups, managing stress, maintaining proper nutrition, and avoiding harmful substances are essential.

3. Avoiding harmful substances: Pregnant women are advised to refrain from smoking, alcohol consumption, and using recreational drugs. These substances can affect fetal development. So, seeking medical guidance is essential for maintaining a healthy lifestyle during pregnancy.

4. Healthy pregnancy diet: A balanced and nutritious diet during pregnancy supports optimal fetal development. Therefore, include essential nutrients like folic acid and omega-3 fatty acids to promote the fetus's brain and cognitive growth.

5. Minimizing environmental toxins: While the precise relationship between environmental toxins and ASD risk is not fully understood, minimizing exposure to pollutants, pesticides, and chemicals during pregnancy is a preventive approach to fostering a healthy environment for both the mother and the fetus.

6. Genetic counseling: If you have a family history of ASD or related conditions, seeking genetic counseling can provide valuable insights about hereditary. However, it is crucial to understand that the genetic basis of ASD is complicated, and its predictability is also limited.

7. Nurturing parental well-being: Supporting and empowering parents, especially those concerned about developmental issues, can significantly improve a child's well-being. Improving the home environment, reducing stress, and creating a nurturing environment can substantially assist in the development of children.

How to diagnose Autism in children?

The diagnosis of autism spectrum disorder is a multistep procedure involving:

1. Clinical observation: The diagnostic process for Autism involves meticulous clinical observation by healthcare professionals specializing in neurodevelopmental disorders. They keenly assess behaviors, communication patterns, and social interactions to identify potential indicators of Autism.
2. Developmental history assessment: Gaining insights into a person's developmental history is a crucial step in evaluation. To establish a comprehensive understanding, healthcare providers inquire about the child's significant milestones, language acquisition, social engagement, and early behavioral traits.
3. Standardized screening tools: Utilizing standardized screening tools is crucial. These include structured questionnaires and checklists that caregivers, teachers, and parents complete to provide additional information for assessment.
4. Multidisciplinary collaboration: Diagnosis necessitates a collaborative effort among diverse specialists such as pediatricians, clinical psychologists, speech therapists, and occupational therapists. Their collective approach ensures a holistic evaluation of the individual's characteristics.
5. Application of diagnostic criteria: The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) outlines the requirements for diagnosing Autism. Healthcare professionals evaluate the individual against these established criteria to interpret the condition.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides criteria for diagnosing mental disorders. The DSM-5 criteria for diagnosing autism spectrum disorder (ASD) are as follows:

• Persistent deficits in social communication and social interaction across multiple contexts: This includes difficulties in social-emotional reciprocity, nonverbal communication, developing and maintaining relationships, and understanding and responding to others' emotions.
• Restricted, repetitive patterns of behavior, interests, or activities include stereotyped or repetitive motor movements, abnormal goods in intensity or focus, and inflexible adherence to routines or rituals.
• Symptoms must be present in the early developmental period (but may not fully manifest until social demands exceed limited capacities). It means signs must be present before three years old, although they may only be fully apparent later.
• Symptoms cause clinically significant impairment in social, occupational, or other important areas of functioning. It means that symptoms must cause significant problems in a person's life.

6. Differential diagnosis: The diagnostic process also involves differentiating Autism from other conditions with similar traits. It requires a thorough assessment to rule out conditions that mimic autistic manifestations.

7. Longitudinal assessment: Autism diagnosis remains an ongoing process, adapting to changes as the individual grows and develops. Regular inspections ensure the accuracy and relevance of the diagnosis over time.

Autism Spectrum Disorder (ASD) can have three distinct severity levels, including:

Level 1: Requiring support

Individuals at Level 1 exhibit challenges primarily within social communication and interaction. It is challenging for them to initiate and sustain conversations, comprehend social cues, and establish relationships despite possessing verbal communication skills. Exceptionally, repetitive behaviors and routines may be noticeable, albeit to a lesser extent. This group requires assistance to facilitate their social interactions and navigate daily routines.

Level 2: Requiring substantial support

Level 2 corresponds to individuals with notably amplified social communication and interaction challenges. Expressing themselves through talking becomes limited, and participation in social interactions may prove challenging. Heightened repetitive behaviors and restricted interests manifest, accompanied by a pronounced resistance to changes in routines or environments. This group requires substantial support in managing their daily routines and facilitating engagement in social contexts.

Level 3: Requiring very substantial support 

Level 3 characterizes individuals necessitating a high degree of support. Their difficulties are markedly severe in the realm of social communication and interaction. Verbal communication may be minimal. Profound repetitive behaviors and intense preoccupations are evident, accompanied by a distinct preference for routines and aversion to changes. This group demands comprehensive and physical support to enable the execution of daily tasks and the negotiation of various life aspects.

While there is no cure available for autism spectrum disorder (ASD), various medical interventions can significantly improve the quality of life for people with ASD. The optimal treatment approach depends on each person's physical and psychological condition. ASD treatment generally encompasses a combination of strategies, including:

1. Applied Behavior Analysis (ABA): ABA is a therapy that employs positive reinforcement to modify behavior. It aids individuals in acquiring new skills, enhancing social interactions, and reducing problematic behaviors. According to one research, there were notable improvements in social and communication skills among children with ASD undergoing ABA therapy.

2. Speech and language therapy: These therapies focus on improving communication skills, encompassing speaking, comprehension, and interaction. Studies in the "Journal of the American Academy of Child and Adolescent Psychiatry" evidenced substantial advancements in language abilities among children with ASD who received speech and language therapy.

3. Occupational therapy: Occupational therapy hones fine and gross motor skills and daily life skills such as dressing and eating independently. "Occupational Therapy Journal of Research" findings revealed significant enhancements in motor skills among children with ASD undergoing occupational therapy.

4. Sensory integration therapy: The goal of this intervention is to help people with Autism Spectrum Disorders cope with sensory overload caused by loud noises, bright lights, and other sources of sensory stimulation.

5. Medication: Certain medications can help reduce specific ASD symptoms, such as anxiety, depression, and aggression. However, it's essential to understand that medicine does not offer a cure for ASD. Other treatments should complement its use.

The prognosis of Autism Spectrum Disorder (ASD) unfolds uniquely for each individual, resembling a tapestry woven with diverse threads of factors. Like a journey through uncharted terrain, various elements can influence the course of ASD and the shape of an individual's trajectory.

• Early intervention's impact: Initiating interventions early in life can profoundly influence the trajectory. Early diagnosis and tailored therapies like applied behavior analysis (ABA), speech therapy, and occupational therapy can improve communication skills, social interactions, and overall progress.
• Tailoring the approach: Just as a painter crafts a canvas, the doctor fine-tunes the treatment plan to match an individual's distinct qualities. Responses to treatment are as diverse as the colors on an artist's palette, requiring customization to meet specific strengths and challenges.
• Power of Supportive Surroundings: An environment brimming with understanding and support acts as a beacon of hope. The nurturing environment of home, school, and community can majorly contribute to an individual's growth and development, revealing opportunities to move forward.
• Addressing co-occurring aspects: The mosaic of ASD often includes co-occurring conditions like anxiety, ADHD, or intellectual disabilities. Attending these conditions can amplify overall functioning and enrich the individual's quality of life.
• Lifelong learning: ASD, akin to an ongoing odyssey, is marked by continuous learning and skill refinement. As individuals navigate challenges and harness strengths, they journey toward increased autonomy and self-mastery.
• Navigating the passage to adulthood: Transition from adolescence to adulthood is transformative. This course requires meticulous planning and access to support services, guiding individuals toward increased independence and self-reliance.
