What is Autism?
Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects how the brain develops and processes information. It mainly influences social communication, interaction, behaviour patterns, and sensory responses.
Autistic individuals may experience differences in understanding social cues, communicating needs, adapting to changes, or processing sounds, lights, textures, and other sensory experiences.
The term "spectrum" reflects the wide variation in characteristics and support requirements. Some individuals may live independently with minimal support, while others may require lifelong assistance with communication, education, daily activities, and healthcare needs.
Autism is not caused by poor parenting and is not an illness that can be transmitted from one person to another. Research suggests that genetic and developmental factors contribute to the condition.
What are the Types of Autism?
Autism is currently diagnosed as autism spectrum disorder (ASD). The DSM-5 classifies autism according to the level of support an individual requires. These include:
-
Level 1 Autism Individuals with level 1 autism may struggle with social communication and adaptation to changes. These individuals may be capable of doing most tasks on their own but will require some form of assistance with social interactions, organisation, or transitions.
-
Level 2 Autism Individuals with level 2 autism may have more obvious problems with both verbal and nonverbal communication, and they need significant external support. Restricted/repetitive behaviours of these individuals may interfere more with everyday tasks and adaptation to changes.
-
Level 3 Autism Individuals with level 3 autism need very significant support because they have severe problems with social communication and considerable difficulty adapting to changes. In these people, restricted/repetitive behaviours have a considerable impact on everyday life. This classification provides information about an individual's needs for support rather than describing the overall abilities or value of the individual. Support needs may also vary depending on the context and stage of development.
How Common is Autism in India?
The prevalence of autism in India is difficult to determine accurately due to limited large-scale population-based studies and the absence of a nationally representative estimate. Nonetheless, a study reviewing the prevalence of autism in India reported that approximately 1 in 65 children aged 2–9 years in India may have autism spectrum disorder.
However, this estimate is based on available research studies and should not be considered a confirmed national prevalence rate.
What are the Symptoms of Autism?
Autism symptoms can vary considerably between people. Some characteristics may become noticeable during early childhood, while others may become clearer when social and communication demands increase. The table below presents the early warning signs and advanced symptoms of autism:
| Early Warning Symptoms | Advanced/More Noticeable Symptoms |

Note: Not everyone with autism will exhibit all of these symptoms. Symptoms and their degrees of severity may vary from one individual to another. Also, some symptoms may be more pronounced when a child joins school.
Diseases Similar to Autism?
People may often confuse autism with other diseases like ADHD and developmental language disorder, as all of these conditions cause differences in brain development. However, these conditions are distinct based on how they occur, how they affect social interaction and communication, and how they are diagnosed.
Below is a comparison to help distinguish each condition:
Autism Spectrum Disorder (ASD) vs. ADHD vs. Developmental Language Disorder
| Feature | Autism Spectrum Disorder (ASD) | ADHD | Developmental Language Disorder |
| How Does It Happen? | Differences in brain development impact social communication, interaction and behaviour | Differences in brain development impact attention, activity and impulse control | Difficulty understanding or using language persistently |
| Main Difficulty | Social communication, social interaction and restricted or repetitive behaviours | Attention, hyperactivity and impulsivity | Difficulty understanding or using language |
| Social Interaction | Difficulty understanding social cues, maintaining interactions or forming relationships | May interrupt, have trouble maintaining focus in conversation and/or difficulty with turn-taking | Social difficulties could be due to difficulty understanding or using language |
| Communication | Differences in verbal and nonverbal communication occur frequently | Could have communication difficulties, but social communication difficulties do not define the diagnosis | Difficulty understanding or using language is the core issue |
| Repetitive Behaviours | Repetitive movements, speech or actions may happen | Not a core feature | Not a defining feature |
| Diagnosis | Based on the history of development and social communication and restricted or repetitive behaviours evaluation | Based on issues, history of development and attention, hyperactivity and impulsivity evaluation | Based on language ability evaluation and the history of development |
What Causes Autism?
Autism does not have any known singular cause. Research shows that there are genetic and developmental reasons why brain development is affected. Some possible contributing causes of autism include:
-
Genetics: Genetics plays a significant role in autism. Certain genetic variations may increase the likelihood of developing autism, and the condition can also occur alongside some genetic disorders.
-
Brain Development: Differences in brain development, connectivity, and information processing may contribute to autistic characteristics.
-
Birth Complications: Certain pregnancy and birth-related factors, such as premature birth or low birth weight, have been associated with a higher likelihood of autism. However, these factors do not directly determine whether a person will develop autism.
These causes contribute to the chances of having autism, but they do not determine autism occurrence.
What are the Risk Factors for Autism?
The following risk factors have been found to be related to an increased probability of developing autism:
-
Family History: Individuals who have siblings or immediate family members with autism are more likely to develop the condition.
-
Genetic Disorders: Autism is linked to some genetic or chromosomal disorders.
-
Advanced Parental Age: The risk of having an autistic child increases when parents are relatively older than average during the child's birth.
-
Premature Birth: Premature babies are more prone to developing autism, along with other developmental problems.
-
Low Birth Weight: Babies who have low birth weight are more likely to have autism.
-
Birth Complications: Maternal diabetes is one of the crucial risk factors related to autism.
What are the Complications Associated With Autism?
Some autistic individuals have accompanying medical conditions that may cause functional problems. The most common accompanying problems with autism are as follows:
-
Epilepsy: There is a higher occurrence of seizures among autistic individuals compared to the general population.
-
Sleep Disorders: Problems with sleep and insomnia are common.
-
Anxiety: Some autistic individuals suffer from anxiety disorders due to communication problems and sensory or social situations.
-
Depression: Depression affects autistic adolescents and adults, especially if they do not have enough support.
-
Feeding Problems: Children who are autistic tend to have feeding problems since they may eat only certain foods.
-
Sensory Problems: Sensitivity to sounds, lights, textures, and other sensations could cause difficulties with activities.
-
Communication Problems: Communication problems prevent some individuals from being able to communicate their illnesses.
When Should You See a Healthcare Provider?
You should consider having an autism assessment if a child displays any ongoing worries regarding communication, socialisation or behaviour. Consider seeking medical support as soon as possible if the child:
-
Does not respond consistently to his/her name.
-
Has limited or no language according to his/her developmental level.
-
Displays regression in language or social ability.
-
Demonstrates very poor social interaction.
-
Performs repetitive actions.
-
Gets extremely distressed from usual changes in routines.
-
Shows unusual responses to sights, sounds, or any sensory experience.
A loss of previously acquired language or social skills deserves prompt assessment.
How is Autism Diagnosed?
No blood test, brain scan, or any other single test can diagnose autism. It requires development and behavioural observations. The assessment process for autism may consist of:
-
Developmental History The doctor asks questions regarding the child's development, behaviour, speech, and play.
-
Interview With Parents/Caregivers The doctor may seek information from parents/caregivers regarding the child's behaviours in different situations.
-
Behavioural Observation A trained professional observes the child's behaviours related to communication, interaction, playing, and repetitive behaviours.
-
Developmental Testing Developmental testing includes investigating the areas of communication, cognitive learning, adaptive functioning, and others.
-
Hearing Screening It includes testing hearing problems where there are problems involving speech and responses to sound.
-
Testing for Associated Disorders The doctor may investigate whether associated disorders like ADHD, epilepsy, intellectual disabilities, and anxiety problems are present or not.
-
Genetic testing Genetic counselling or testing is done in selective cases based on clinical history.

How is Autism Treated and Managed?
There is currently no treatment that cures autism. Management of the condition focuses on helping autistic individuals develop communication, social, learning, behavioural, and daily living skills according to their individual needs.
Treatment plans are personalised based on:
-
Age
-
Communication ability
-
Developmental level
-
Learning needs
-
Associated health conditions
The treatment options for autism are as follows:
-
Behavioural Therapy Behavioural interventions can help individuals develop skills, manage challenging behaviours, and improve independence.
-
Speech and Language Therapy Speech therapy helps improve communication abilities, including verbal communication, understanding language, and alternative communication methods.
-
Occupational Therapy Occupational therapy supports daily activities, motor skills, sensory processing, and independence.
-
Educational Support Individualised education programmes help children learn according to their abilities and developmental needs.
-
Psychological Support Counselling and psychological interventions may help manage anxiety, emotional challenges, and behavioural concerns.
-
Family Support Parents and caregivers may benefit from guidance on communication strategies, routines, and long-term support planning.
Medications Used to Treat Autism
Medicines cannot address the primary issues with autism. They are used for treating particular symptoms or related conditions when needed. The common medicines prescribed by doctors for autistic people are as follows:
-
Anti-psychotic Drugs: Drugs such as risperidone and aripiprazole can be used to control severe irritability and aggression and self-injurious behaviour related to autism.
-
Other Drugs: Based on the symptoms exhibited by the individual, medication may be given to control related conditions like anxiety, insomnia, ADHD symptoms, or epilepsy.
Note: The medicines for autism depend on the individual's symptoms, overall health, and stage of the condition. As treatment needs can vary, medicines should always be taken under the guidance and supervision of a qualified healthcare professional.
Living with Autism: Daily Challenges, Caregiving and Expenses
Autism may impact communication, social skills, education, employment, and daily functioning. The extent to which support is needed depends on individual symptoms. Some crucial difficulties that should be considered include:
-
Challenges
- Challenges in Daily Activities: Communication, social skills, sensory processing, and behaviour differences may make some activities hard to do.
- Communication Difficulties: Some individuals may have problems expressing their needs, understanding social cues, or communicating in certain situations.
- Educational and Work Difficulties: Individuals may struggle to participate in school and the workplace due to communication, sensory sensitivities, and difficulty adapting to change.
- Change and Routine: Any change in familiar routine or environment may lead to stress and difficulty carrying out daily activities.
- Sensory Challenges: Difficulty with sounds, lights, textures, smells, or touch may affect daily activities and social interactions.
-
Caregiving and Patient Safety
- Daily Support: Daily assistance may involve communication and routine assistance or even assistance with daily activities like personal care, based on the requirements of the individual.
- Communication Support: The caregiver may assist the autistic individual in communicating in a way that suits their needs.
- Routine Support: Assistance in following a regular routine may be helpful for the autistic individual, along with preparation for any change that is anticipated.
- Safety Assistance: Caregivers should determine safety issues for the individual and provide assistance accordingly.
- Follow-Up Needs: Follow-up assistance may be needed in monitoring the developmental needs of the individual, along with behavioural and educational assistance.
-
Expenses
- Medical and Other Costs: Costs may include medical consultations, diagnosis, medicine for related symptoms, and other such services.
- Therapy and Educational Costs: Families may spend money on speech and language therapy, occupational therapy, behaviour modification, special education, and other such services.
- Long-Term Financial Planning: Autism may require ongoing support, and understanding therapy, educational, and medical costs will be helpful in financial planning in the long term.
What is the Prognosis for Autism?
Autism is a lifelong neurodevelopmental disorder. The symptoms and the level of support an autistic person needs can vary with age. While some autistic individuals acquire effective communication, academic and self-help skills, others require extensive support in all aspects of their lives throughout their lifespans.
Early diagnosis can help to access developmental and educational interventions. However, there is no standard outcome for every autistic individual.
How Can I Prevent Autism?
Currently, there is no proven way to prevent autism. Autism has a strong developmental and genetic component, and several associated factors contributing to its development cannot be controlled.
However, parents can support healthy development through routine healthcare, appropriate nutrition, regular developmental monitoring, and timely assessment of developmental concerns.
Autism Treatment Cost in India
The costs of autism-related care vary greatly, as it can consist of frequent visits for therapy sessions and is not a one-off treatment. The cost would depend on the kind of therapy needed and how frequently it is required. The cost also varies across different cities in India.
The approximate costs of autism-related care are presented in the table below:
| Treatment Component | Approximate Cost |
| Occupational therapy | ₹800 to ₹2500 per session |
| Speech therapy | ₹500 to ₹2500 per session |
| ABA-based behavioural therapy | ₹500 to ₹3000 per hour |
| Special education | ₹30 to ₹2000 per hour |
| Autism therapy and intervention | ₹3 lakh to ₹5 lakh per year |
Note: The above costs are estimates. Actual prices may vary depending on the hospital, city, and the number and type of therapy sessions required.
Does Health Insurance Cover Autism in India?
Yes, health insurance plans cover medical expenses incurred on the treatment of autism spectrum disorder. Some insurers also offer specialised plans for autistic children that cover hospitalisation expenses, day care procedures, OPD expenses, and modern treatments . However, the level of coverage would depend on the policy terms and conditions.
Waiting periods may apply before a claim for autism can be raised. While the initial waiting period will be of 30 days, the PED waiting period can be up to 3 years. It is always advisable to check the policy document before making a purchase or a claim.
How Much Health Insurance Coverage is Needed for Autism?
The required health insurance cover for an autistic individual depends on factors like age, pre-existing illnesses, and the types of therapies and healthcare services availed by them.
A medical coverage of ₹10 lakh could be adequate to cover all eligible medical expenses for autism-related care. A higher coverage of ₹10 lakh can provide better coverage for those who develop complications and require extensive hospitalisation.
