ADHD and autism share various symptomatic similarities that make it difficult to diagnose. Clinically, ADHD affects one’s attention, activity level, or impulsivity. Subsequently, ASD affects social interactions, communication, sensory processing, and behavioral patterns. In many instances, both conditions can co-exist, mediated by overlapping neurological and genetic factors. In fact, the global data reflect that 21% of children affected with ADHD are autistic, while 28% of autistic children meet ADHD criteria [1]. Despite the similarities, both ADHD and Autism are distinct conditions. Both require unique diagnosis and support to improve the quality of life of the affected individuals. Recognizing the difference is essential in developing personalized interventions.
Understand the Basics: ADHD and Autism?
What is ADHD?
ADHD is characterized by impulsive behaviour, inattention, or hyperactivity. The condition mostly occurs during early years and persists as a lifelong condition. Individuals affected with ADHD find difficulty in sitting still, concentrating, or thinking before reacting. Three major subtypes of ADHD include:
- Hyperactive-impulsive
- Inattentive
- A combination of both
What is Autism Spectrum Disorder (ASD)?
A diverse group of neurological, behavioral, and social conditions characterizes ASD. Its characteristics appear at an early age, yet can be diagnosed much later. Children affected with ASD display difficulty in social interaction, communication, sensory alteration, or difficulty with focus. The symptoms vary among individuals. For example, some children show higher levels of intelligence but find difficulties in social interaction, while others might require holistic support to lead their lives. Some common symptoms of ASD include:
- The child does not respond to their name
- Shows repetitive behaviour
- Get agitated with a change in patterns or routine
- Avoids eye contact, speaks in monotone
Why Are ADHD and Autism Confused?
ADHD and autism share several behavioral traits, along with hereditary and genetic overlap. Some common traits include:
- Hyperfocus
- Sensory problems, insomnia
- Social challenges like communication interactions
- Difficulty or distinct behavior while making eye contact
- Difficulty in interoception, e.g., notice thirst or hunger
In clinical settings, the overlap of ADHD and autism is common. Infact, their co-existence is termed as ADHD by many. The child with both conditions experiences internal struggles due to contradicting traits. For instance, the child can experience heightened versions of ASD or ADHD, like intense focus on certain hobbies or interests.
What are the Overlapping Signs Between ADHD and ASD?
ADHD and autism share certain similar signs and symptoms, which mask each other. These include:
Attention
- Child appears disengaged or disinterested
- Finds it challenging to focus on a task or a conversation
Social Interaction
- The child struggles to understand the social cues
- Finds difficulty in making friends and maintaining friendships
Emotional Regulation
- Common emotional traits include getting frustrated, sudden meltdowns, or emotional outbursts
- The presence of sensory overload (loud music or too much light) or other environmental triggers makes them agitated
Communication
- Finds difficulty in communicating their wants and feelings
- Experience challenges in reciprocal communication
- Delayed or atypical communication patterns
Executive Function Challenges
- Difficulty in planning or executing plans
- Problem with time management or timely completion of tasks
What are the Key Differences?
Understanding the key differences is crucial for adequate diagnosis.
Social Interaction
- A child with ADHD desires social engagement but finds difficulty in maintaining attention
- An autistic child finds difficulty in social communication and interaction style
Focus & Interests
- ADHD children find difficulty in maintaining attention; they might seem to obsess over certain things, but lose focus easily
- An autistic child can show a limited scope of interest, show an obsession with things of their interest, and ignore what does not interest them
Behavioral Patterns
- Children with ADHD show impulsivity and spontaneity
- An autistic child prefers following distinct routines and predictable patterns
Communication
- More distinct among autistic children. They find difficulty in expressing feelings, emotions, thoughts, etc. Find difficulty in developing both verbal and non-verbal communication
- Some ADHD children show communication irregularities such as continuous talk, disinterested in noticing how their words affect other individuals, or lose focus in mid-conversation
Routine
- ADHD children quickly become bored with routine, and seem disengaged in the classroom
- Autistic children demonstrate more insistence on sameness, want to adhere to the routine or ritualized patterns
How are ADHD and Autism Clinically Distinguished?
Based on ICD-10, ADHD and autism are distinct neurodevelopmental conditions and possess distinguished diagnostic criteria.
Table: ADHD and Autism: Differences Based on ICD-10
| Features | ADHD ICD-10 | Autism spectrum disorder ICD-10 |
| Category | Hyperkinetic disorder (HD) | Pervasive developmental disorder (PDD) |
| Code | F90.0: Disturbed activity and attention
F91.0: Marks HD F90.8: Other HD F90.9: HD, unspecified |
F84.0: Childhood autism
F84.1: Atypical autism F84.5: Asperger syndrome F84.9: PDD, unspecified |
| Characteristics | Inattention, hyperactivity, impulsivity | Deficient in social interaction, communication, repetitive behaviour |
| Age onset | Evident before 7 years | Symptoms appear in early childhood, often before 3 years |
*NOTE: In case of ADHD and autism co-existence, clinicians performing dual diagnosis
What are Treatment or Support Strategies?
While talking about ADHD and autism, treatment strategies are distinct, as ‘one size does not fit all’. The effective support depends on the child’s symptoms, severity of the condition, and co-existing challenges. Therapy for Autism Spectrum Disorder and ADHD involves:
- Behavioral Therapy: Clinicians undertake evidence-based approaches for developing personalized treatment plans. The focus remains on the indifferent behaviour of the child. The therapist aids in developing essential skills of the child, emotional regulation, and managing sensory distress.
- Occupational Therapy: A therapist supports children in developing daily life routines. It enables children to improve focus, learn motor skills, and improve their motor function.
- Speech Therapy: Language and communication development is a common problem with autistic children. Treatment for Autism in India involves speech therapy that enables children to learn both verbal and nonverbal communication. Children start to express their feelings and state discomfort. In a social setting, a child does not feel tense and learns to interact eventually.
- Medication: Clinicians prescribe medication for both ADHD and autistic children for managing co-existing health conditions. This includes managing psychological conditions like anxiety, depression, stress, hyperactivity, etc. Sometimes children experience conditions like gastrointestinal disorders, immune dysregulation, joint hypermobility, or insomnia.
- Support for Caregivers: effective ADHD and ASD management requires a holistic approach. The parent or primary caregiver of the child is the first point of interaction. Seeing a child’s indifferent behaviour can be overwhelming. Facilitating adequate support to parents enables them to learn and guide their child efficiently.
What are Emerging Treatment Options?
Growing interest in specialized and regenerative care has transformed the Treatment for Autism in India. Regenerative medicine, including stem cell therapy, has shown advanced potential in combating neurodegenerative diseases, including ADHD and autism. The key advantages of stem cell therapy involve:
- Regeneration and Repair: Mesenchymal stem cells (MSCs) are widely explored as they can differentiate into distinct cell types. MSCs release regenerative signals that support the de-differentiation of neural cells and replace damaged ones. They also stimulate repair mechanisms and create a supportive environment for the surrounding cells/tissue
- Anti-Inflammation and Immunomodulation: Stem cells modulate immune response; they release various anti-inflammatory molecules that neutralize pro-inflammatory signals in the brain.
- Neuroprotection: Stem cells release various neurotrophic factors and growth factors that facilitate neural protection [2]
*NOTE: Currently, the implications of stem cell therapy for neurodegenerative diseases are yet to be investigated. It is crucial to consider superior quality stem cells and determine a child’s suitability to opt for the treatment. Clinicians combine regenerative medicine as a supportive effort with traditional therapies for improved outcomes. Advancells, India, is a leading stem cell manufacturing laboratory that supplies superior quality stem cells for various chronic conditions, including neurodegenerative disease. The cells undergo stringent quality checks and are maintained at optimal conditions before dispatch.
Conclusion
ADHD and autism might appear similar in terms of certain symptoms, yet understanding their distinct features is crucial for accurate diagnosis and development of individualized care. However, there is no definite cure for either neurological condition. Growing research with regenerative medicine holds new hope for better improvement of the child’s condition.
