Autism is a common developmental disorder today, affecting communication skills, social interaction, and behavioral development in children and adults. In this article, we provide detailed information about autism, including its symptoms, causes, and effective treatment methods, shared from the experience of Dr. Nguyen Hoang Yen, a Specialist Level II and one of the leading experts in psychiatry in Vietnam.

We hope that with this knowledge, you will gain a deeper understanding and know how to best support individuals with autism.

What is autism?

What is autism?

Autism (also known as Autism Spectrum Disorder) is a group of developmental disorders that affect a person’s ability to interact socially, communicate, and exhibit behaviors. Common manifestations include difficulty understanding and responding to others’ emotions, limited participation in social activities, and frequent repetitive behaviors or routines.

Typical symptoms of autism

Individuals with autism often show clear signs in behavior, emotions, and communication. Symptoms can appear early and vary across different developmental stages.

Impaired communication and social interaction

Impaired communication and social interaction

Children often have difficulty maintaining eye contact, smile less in response, or rarely initiate conversation. Many children have delayed speech or do not use language to communicate, instead relying on repetitive gestures. When playing with peers, they can become isolated because they do not know how to share or engage in two-way interactions.

Behavioral and interest disturbances

Behavioral and interest disturbances

Individuals with autism often exhibit repetitive behaviors, special interests, or fixations on specific topics. For example, some children enjoy arranging objects in a certain order or are strongly attracted to numbers. They may react strongly to changes in environment or routines: only taking one route, eating one specific food, or sitting in the same place. They may have unusual, narrow, and specialized interests (e.g., memorizing license plates, fascinated by train history…). This can hinder their ability to adapt in educational and social settings.

Sensory and emotional disturbances

Some individuals with autism overreact or are under-sensitive to sounds, light, or tastes. Additionally, poor emotional regulation can lead to anger outbursts or anxiety when facing stressful situations.

Causes of autism

To date, no single study fully explains the development of autism. However, it is believed that multiple factors combined can contribute to the disorder.

Genetic factors

One of the most common causes of autism is genetics. Changes in one or more gene segments affecting nervous system development can increase the risk of autism spectrum disorder (ASD) in children. Autism shows a strong hereditary pattern.

  • If one child in a family has autism, the risk of a second child having it may increase by approximately 10–20 times compared to the general population.

  • In identical twins, the likelihood that both have ASD can reach 70–90%, indicating a strong genetic role.

  • Hundreds of different genes have been associated with ASD, including those regulating synapse development, neurotransmission, and neural network formation, such as SHANK3, NRXN1, NLGN3/4, CHD8…

  • De novo gene mutations (appearing for the first time in the child, not inherited from parents) may also contribute to the disorder.

Internal factors

Some abnormalities in the development of the nervous system have also been observed in individuals with autism. These factors include brain structure, neural connectivity, and the balance of neurotransmitters.

Abnormalities in brain structures such as the amygdala, cerebellum, or prefrontal cortex can alter the ability to regulate emotions and behavior.

Imbalances in neurotransmitters such as serotonin, dopamine, and GABA are also commonly found in people with autism.

Certain maternal immune disorders during pregnancy may affect the fetal nervous system development.

External factors

In addition to genetics and biology, the living environment can also influence the risk of autism. These influences may occur during the prenatal period or at birth.

  • Children are at higher risk if the mother is exposed to toxic substances (lead, mercury, pesticides) during pregnancy.

  • Pregnancy complications such as infections, preeclampsia, premature birth, or low birth weight.

  • Viral infections like rubella or birth complications (asphyxia, oxygen deprivation to the brain) are also considered risk factors.

  • Parental age, especially older fathers, is associated with an increased risk of autism spectrum disorder in children.

Autism treatment

Although autism cannot be completely cured, there are many treatment and intervention methods that can help improve symptoms and the quality of life for individuals with this disorder.

Purpose of treatment

Purpose of treatment

The goal of autism treatment is not to “completely cure” the disorder, but to help patients:

  • Improve communication, behavior, and social skills

  • Increase independence in learning and daily activities

  • Minimize harmful behaviors or associated disorders

  • Support families with knowledge and tools to provide long-term guidance

Behavioral intervention

Behavioral intervention, also known as Applied Behavior Analysis (ABA), is one of the most common treatment methods for autism.

ABA uses the principle of positive reinforcement, teaching children from small skills such as making eye contact or greeting others, to more complex skills like teamwork.

Other therapies, such as TEACCH (Treatment and Education of Autistic and Communication related handicapped Children), emphasize creating a clearly structured learning environment to facilitate the child’s learning.

Early behavioral therapy, like the Early Start Denver Model, is particularly effective for children under 5 years old.

Language and communication intervention

Language and communication intervention

Language is the biggest barrier for individuals with autism. Therefore, language and communication intervention is considered a highly effective treatment method.

Speech therapy focuses on improving pronunciation, expanding vocabulary, and developing body language skills.

Children are guided to use systems like the Picture Exchange Communication System (PECS) or technology-assisted communication tools.

Experts emphasize collaboration between parents and therapists so that language practice occurs daily, not just in the clinic.

Medical treatment

In some cases, doctors may prescribe medication to manage certain issues in patients with autism. Medication does not cure autism but may be necessary to control specific symptoms.

  • Anti-anxiety and antidepressant medications help reduce stress and obsessive behaviors.

  • Antipsychotic drugs, such as risperidone, may be used to control aggressive or agitated behaviors.

  • Medications for attention deficit hyperactivity disorder (ADHD) are applied if the child also has hyperactivity issues.

Medication use must be closely supervised by a specialist in psychiatry and should never be self-administered.

Educational methods and family support

Educational methods and family support

The timing of detecting autism signs and the effectiveness of treatment largely depend on the attitude and role of the family. Families play a key role in the treatment process, helping patients recover more quickly and reintegrate into the community.

Children with autism should participate in inclusive classes with personalized curricula.

Parents need to be trained to understand and support their child, allowing close collaboration with schools and specialists.

Community support groups and intervention centers are valuable resources, helping families reduce stress and learn from the experiences of others in similar situations.
