"Celebrating Neurodiversity: Understanding Autism in 2025

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by challenges in social interaction, communication, and repetitive behaviors. It seems likely that understanding and supporting autistic individuals is crucial, especially on World Autism Awareness Day, which highlights the importance of neurodiversity and acceptance.

Understanding Autism: Definition and Characteristics

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by persistent challenges in social communication and interaction, alongside restricted and repetitive patterns of behavior, interests, or activities. The World Autism Awareness Day on April 1, is a poignant moment to reflect on what autism means—not just clinically, but for the individuals and families living with it every day.

This condition manifests uniquely across a spectrum, meaning no two autistic individuals are exactly alike, which is why understanding its nuances is so vital. From a quiet child fixated on spinning objects to a teenager struggling to navigate social cues, autism touches lives in diverse ways, often revealing remarkable strengths alongside its challenges. As a psychiatrist, I’ve seen how early recognition and support can transform outcomes, making awareness—especially on this global day of recognition—a powerful tool for change. Embracing neurodiversity isn’t just a concept; it’s a call to action to celebrate these differences and build a more inclusive world.

Prevalence and Challenges in India

In India, the prevalence of autism remains a subject of ongoing research, with estimates varying due to differences in diagnostic tools and awareness. Some studies suggest a prevalence of around 1 in 68 children, as noted in a 2021 study published in the Indian Journal of Pediatrics, while global figures from the WHO indicate 1 in 100 Early Detection and Diagnosis of Autism in India. This variability underscores the need for standardized research, particularly given the diverse cultural and socioeconomic landscape.

Challenges include stigma, lack of awareness, and limited access to diagnostic and therapeutic services, especially in rural areas, which can delay interventions and exacerbate outcomes.

Early Signs and Symptoms for Detection: Age-Wise Guide

Early detection is crucial for initiating timely interventions. Below is an age-wise guide for signs and symptoms, along with at-home detection tips:

• From Birth to 6 Months:

  • Signs: Reduced eye contact, lack of response to sounds or voices, limited smiling in response to social stimuli.

  • At-Home Detection: Observe if the baby makes eye contact during feeding or responds to your voice; note any unusual irritability.

• 6 to 12 Months:

  • Signs: Delayed or absent babbling, not responding to name calling, lack of gestures like waving.

  • At-Home Detection: Check if the baby babbles or coos by 9 months; use the M-CHAT-R/F screening tool available online for initial assessment.

• 12 to 18 Months:

  • Signs: Absence of pointing or showing objects, limited or no speech, repetitive behaviors like hand flapping.

  • At-Home Detection: Encourage pointing to objects and note if the child uses words or gestures; look for repetitive actions during play.

• 18 to 24 Months:

  • Signs: Not using simple phrases, difficulty with pretend play, unusual attachments to objects.

  • At-Home Detection: Observe if the child engages in imaginative play, like feeding a doll; monitor for excessive lining up of toys.

Screening tools like the M-CHAT-R/F can help identify potential concerns, but a definitive diagnosis requires professional evaluation by a pediatrician or psychiatrist.

Common Comorbidities with Autism

Autism often co-occurs with other conditions, which can complicate diagnosis and management:

• Intellectual Disability: About 30-50% of autistic individuals may have intellectual disabilities, affecting cognitive and adaptive functioning.

• Attention-Deficit/Hyperactivity Disorder (ADHD): Common, with overlapping symptoms like impulsivity and inattention, seen in around 30-40% of cases.

• Anxiety Disorders: High prevalence, with social anxiety being particularly common, affecting up to 40% of autistic individuals.

• Epilepsy: Approximately 20-30% of autistic individuals may develop seizures, especially in those with intellectual disability.

• Gastrointestinal Issues: Conditions like constipation and food sensitivities are reported in about 20-30% of cases, often linked to sensory sensitivities.

• Sleep Disorders: Insomnia and other sleep issues affect around 50-80% of autistic children, impacting daily functioning and behavior.

These comorbidities require a holistic approach to care, addressing both autism and associated conditions for better outcomes.

Treatment and Management Practices in India

In India, managing autism spectrum disorder (ASD) involves a multidisciplinary approach, combining various therapies and, when necessary, medications to address the diverse needs of autistic individuals. This holistic strategy reflects the country’s growing commitment to supporting neurodiversity, especially as awareness increases by World Autism Awareness Day 2025. Below are the common treatment practices:

• Behavior Therapy (ABA - Applied Behavior Analysis):

  • Focuses on reinforcing positive behaviors and reducing challenging ones through systematic approaches, often involving rewards and structured routines.

  • ABA is rooted in breaking down complex skills—like sharing or waiting—into small, teachable steps, using positive reinforcement (e.g., praise or small treats) to encourage progress.

  • Sessions are typically intensive, ranging from 20-40 hours per week, and tailored to the child’s specific needs, making it highly individualized.

  • In India, trained ABA therapists work in urban centers like Delhi, Mumbai, and Bangalore, though availability in rural areas remains limited, pushing families to seek online resources.

  • Evidence suggests ABA can significantly improve social and adaptive skills, especially when started early, making it a cornerstone of autism intervention.

• Speech Therapy:

  • Aims to improve communication skills, both verbal and non-verbal, helping individuals express needs and engage socially.

  • Therapists use techniques like picture exchange communication systems (PECS) for non-verbal children, teaching them to use images to request items or express feelings.

  • For verbal children, therapy focuses on articulation, vocabulary expansion, and conversational turn-taking, addressing common delays seen in autism.

  • Speech therapists collaborate with families to practice skills at home, such as using gestures or simple words during daily routines like mealtime.

  • This therapy is vital for reducing frustration and fostering independence, with progress often visible within months of consistent sessions.

• Occupational Therapy (OT):

  • Helps develop skills for daily living, such as dressing, eating, and writing, while also addressing sensory processing issues common in autism.

  • OT includes activities like brushing techniques or swinging to regulate sensory input, helping children who may be overwhelmed by textures or sounds.

  • Therapists assess fine motor skills (e.g., holding a spoon) and gross motor skills (e.g., walking), designing exercises to build coordination and strength.

  • OT is widely available in rehabilitation centers and schools, with therapists often training parents to reinforce skills at home.

  • The goal is to enhance independence and quality of life, enabling autistic individuals to navigate everyday tasks with greater ease.

• Sensory Integration Therapy:

  • Assists in managing sensory sensitivities, like reactions to loud noises or bright lights, through controlled exposure and desensitization.

  • Activities might include playing with textured materials (e.g., sand, water) or using weighted blankets to calm an overstimulated nervous system.

  • Therapists create “sensory diets”—customized plans of sensory input—to help children self-regulate, reducing meltdowns triggered by sensory overload.

  • This therapy is gaining traction in urban clinics, though access remains a challenge in smaller towns, prompting some families to improvise with home-based sensory play.

  • Over time, it can improve tolerance to everyday environments, like crowded markets or noisy classrooms, making social integration smoother.

• Medications:

  • Used to manage associated symptoms like anxiety (e.g., selective serotonin reuptake inhibitors - SSRIs (Sertraline, Fluoxetine, Escitalopram), hyperactivity (e.g., methylphenidate), or aggression (e.g., risperidone), under strict medical supervision.

  • Risperidone, approved for irritability in autism, helps reduce aggressive outbursts or self-injury, but requires monitoring for side effects like weight gain.

  • Methylphenidate, often used for ADHD symptoms in autistic children, improves focus and reduces impulsivity, though it’s not effective for all.

  • SSRIs like fluoxetine may ease anxiety or repetitive behaviors, but dosages are carefully adjusted to avoid overstimulation, a risk in some autistic individuals.

  • Psychiatrists prescribe these judiciously, often as a last resort after behavioral therapies, ensuring families understand benefits versus risks.

• Availability and Emphasis on Early Intervention:

  • India has several centers and institutions—like Action for Autism in Delhi and the Dr. A M Reddy Autism Center in Hyderabad—offering these services, with a growing network in tier-1 and tier-2 cities.

  • Early intervention, ideally before age 5, is emphasized as it leverages neuroplasticity, leading to better long-term outcomes in communication and behavior.

  • Rural access remains limited, but teletherapy and government initiatives are slowly bridging the gap, supported by NGOs and awareness campaigns.

  • Costs can be a barrier, though subsidized programs and government schemes (e.g., National Trust initiatives) help families afford care.

• Alternative Therapies Under Exploration:

  • Alternative approaches like stem cell therapy are under research in India, with trials exploring their potential to improve neural connectivity, though evidence is preliminary.

  • Ayurvedic treatments, such as Shirodhara (oil dripping on the forehead), are used by some families, claiming benefits for relaxation, but lack robust scientific backing.

  • These options are not yet mainstream, and experts caution against relying on them without consulting a multidisciplinary team.
