If your child was recently diagnosed with autism, you’ve likely discovered that autism rarely comes alone. Most autistic individuals, between 70 to 80%, will have at least one additional diagnosis in their lifetime. These are called co-occurring conditions, and they include ADHD, anxiety disorders, sleep disturbances, sensory processing difficulties, gastrointestinal issues, and epilepsy.
Why does this matter for therapy? Because unaddressed co-occurring conditions can sabotage progress. A child whose chronic constipation causes pain may show aggression during therapy sessions. A teen with untreated social anxiety might avoid community activities despite having the social skills to participate. A child with ADHD may seem unmotivated during speech therapy when the real issue is difficulty sustaining attention.
When co-occurring conditions go unrecognized, they mask a child’s true potential and make even the best therapy less effective.
The solution? Comprehensive autism therapy services in Alpharetta that address the whole child, not just the autism diagnosis. At Therapyland, we offer coordinated care that combines ABA behavior therapy, occupational therapy, speech therapy, pediatric physical therapy, and counseling to address multiple conditions simultaneously.
Our multidisciplinary team doesn’t just treat symptoms in isolation. We look at the complete picture: How is your child’s anxiety affecting their ability to learn new communication skills? Is sensory overload triggering behaviors that seem unrelated? Are sleep issues making it impossible to focus during morning therapy sessions? By identifying and addressing these connections, we create treatment plans that work with your child’s unique profile, not against it.
Ready to see what’s possible when every piece of your child’s puzzle gets the attention it deserves? Contact Therapyland today at 678-648-7644 to schedule a comprehensive assessment.
In this guide, you’ll learn which co-occurring conditions are most common, how different therapies work together to address them, and how to coordinate care for the best outcomes.
Let’s explore how the right support can help your child reach their full potential.

Many individuals with autism spectrum disorder have more than one diagnosis, and therapy teams commonly support children, adolescents, and adults with multiple needs at once. Understanding these categories helps parents and caregivers recognize what their child might be experiencing and why a comprehensive approach to treatment matters.
Epilepsy and seizure disorders are among the best-documented co-occurring conditions in autism. Up to 20 to 30% of autistic individuals experience seizures at some point in their lives, with risk increasing for those who also have intellectual disability. Seizures can look like brief staring spells, unusual movements, or full convulsions, and they can begin in childhood or emerge during adolescence.
Sleep disturbances are even more prevalent. Studies suggest that 50 to 80% of children with autism have significant sleep problems, including difficulty falling asleep, frequent night wakings, or restless sleep. Poor sleep affects everything from daytime attention to emotional regulation, making it harder for children to engage fully in therapy.
Anxiety disorders are extremely common, with approximately 40% of autistic youth meeting criteria for at least one anxiety diagnosis. This might show up as:
Depression occurs at higher rates in autistic individuals than in the general population, particularly in teens and adults who are aware of their social differences. Signs might include prolonged low mood, loss of interest in previously loved activities (including special interests), or negative self-talk.
Obsessive-compulsive disorder (OCD) can overlap with core autism features like repetitive behaviors, though OCD involves intrusive, distressing thoughts and anxiety-driven rituals rather than pleasurable or self-regulating routines.
ADHD commonly co-occurs with autism, affecting an estimated 30 to 60% of autistic children. Symptoms like distractibility, impulsivity, and difficulty sustaining attention compound existing communication challenges and make learning more difficult.
Learning disabilities, including difficulties with reading, writing, or math, are more prevalent in autistic populations. Executive function deficits (trouble with planning, organization, and working memory) are extremely common regardless of IQ and directly impact homework completion, following multi-step directions, and managing routines.
Between 80 to 90% of autistic children have clinically significant sensory processing differences. These can include:
Over-sensitivity (Sensory Avoidance)
Under-sensitivity (Low Registration)
Sensory Seeking
These sensory differences are often addressed through occupational therapy, including environmental modifications, sensory diets, and self-regulation strategies.
Gastrointestinal problems affect an estimated 40 to 80% of autistic children. Chronic constipation, diarrhea, reflux, and abdominal pain are common. Because many children cannot clearly express discomfort, GI issues often manifest as behavior changes, irritability, refusal to participate in activities, or sleep problems. A child who suddenly becomes aggressive during therapy or refuses to sit may actually be experiencing undiagnosed stomach pain.
Food selectivity and restricted diets, sometimes driven by sensory sensitivities to texture, smell, or appearance, can lead to nutritional deficiencies if not carefully managed. Some families also notice food intolerances, allergies, or immune sensitivities that require coordination with pediatricians, gastroenterologists, and feeding specialists.
Parents and therapists can often spot early warning signs of co-occurring conditions through day-to-day changes in mood, sleep, behavior, or learning. Recognizing these patterns early allows for timely adjustments to treatment plans and appropriate referrals.
Watch for sudden changes that go beyond your child’s typical baseline:
These shifts may signal anxiety, depression, or untreated physical pain rather than “behavior problems.” A child who suddenly becomes more aggressive during therapy sessions might be experiencing GI discomfort, dental pain, or seizure-related changes.
Signs that may indicate ADHD, learning disabilities, or even undetected seizures include:
These patterns are sometimes dismissed as “just autism,” which can delay effective treatment and support.
Autistic individuals may express emotional distress through behavior rather than words:
When a child’s meltdowns increase in frequency or intensity, especially with visible worry or panic, an anxiety disorder may be present.
Physical signs that warrant attention include:
Therapists often coordinate with medical providers when these signs appear, ensuring that physical health concerns are addressed alongside behavioral and developmental goals.
Co-occurring conditions are not caused by parenting or a child’s choices. They arise from complex neurological, genetic, and environmental factors that interact in ways researchers are still working to understand.
ASD is highly heritable, with twin studies estimating heritability above 70 to 80%. Many genes associated with autism affect brain development, synaptic function, and the balance of brain signals. Disruptions in these pathways can simultaneously increase vulnerability to epilepsy, intellectual disability, ADHD, and mood disorders.
Certain genetic syndromes that cause autism also carry elevated risks for other conditions, including tuberous sclerosis complex, fragile X syndrome, and specific chromosomal variations. Families with multiple members who have neurodevelopmental or mood disorders often share genetic variations.
Environmental factors during pregnancy and early development may interact with genetic vulnerabilities. Risk-modifying factors include:
Early life stressors such as chronic medical illness, repeated hospitalizations, or adverse experiences like bullying can also influence which co-occurring conditions emerge and their severity.
Core autism features can make everyday environments more stressful, which intensifies co-occurring conditions:
Understanding these causes helps families and clinicians focus on proactive supports and accommodations rather than blame.
At Therapyland, we take a team-based approach to address autism and co-occurring conditions together. Rather than treating each diagnosis in isolation, our multidisciplinary team works collaboratively to create cohesive treatment plans that address your child’s complete profile.
This integrated model means families don’t have to navigate each condition separately or coordinate between disconnected providers. Instead, our ABA therapists, occupational therapists, speech-language pathologists, and mental health professionals work together under one roof, sharing insights and adjusting strategies in real time.
Our ABA therapy programs customize behavior plans when a child also has ADHD, anxiety, or OCD-like behaviors.
Our behavior analysts adjust session length, pace, and environmental setup when sleep or seizure issues are present. We emphasize consistency and routine, principles that are essential for children with autism who also have attention or learning challenges.
Social skills training is another core component of our ABA programming. We teach skills like initiating interaction, turn-taking, managing conflict, and reading social cues. For clients with co-occurring anxiety, our social skills groups incorporate coping strategies and role-playing scenarios to build confidence in a supportive environment.
Our occupational therapists target sensory processing differences, fine motor skills, and daily living tasks. We design individualized sensory diets and regulation plans for children who are over-responsive or under-responsive to sensory input, using strategies like:
Our OT interventions reduce meltdowns caused by sensory overload, helping children participate more successfully in community activities and family routines.
Our speech-language pathologists support clients whose communication is further impacted by anxiety, ADHD, or learning disabilities. We use tools and strategies, including:
Enhancing functional communication is critical when monitoring for co-occurring conditions. When a child can express pain, emotions, discomfort, or preferences, caregivers and therapists can respond before behaviors escalate. A child who learns to say “my stomach hurts” or point to a pain chart is far less likely to show aggression or withdrawal.
What sets Therapyland apart is our commitment to true collaboration. Our coordinated care plans include:
When autism therapy effectively addresses co-occurring conditions, children often make faster and more consistent progress across home and community settings. While timelines vary, many families begin noticing meaningful improvements within the first few months of coordinated care.
Targeted therapy can help children build practical, day-to-day skills, including:
As these skills develop, daily life becomes more manageable for both the child and their family.
Therapy that addresses anxiety, ADHD, or sensory challenges can reduce the frequency and intensity of meltdowns while improving frustration tolerance. Children learn to recognize emotional triggers and apply coping strategies, helping them navigate playgrounds and social outings more successfully.
Stronger emotional regulation supports healthier peer interactions and builds the confidence needed to form friendships.
Managing concerns such as sleep difficulties, anxiety, or chronic discomfort often leads to lower stress levels throughout the household. Parents frequently report that improved sleep and behavior positively affect sibling relationships and make daily routines, errands, and family events easier to plan and enjoy.
Addressing co-occurring conditions early and consistently is associated with:
Every child’s path is different, but comprehensive, integrated therapy can create lasting benefits that extend well beyond early intervention.

Evaluations can begin as early as 18 to 24 months if there are developmental concerns. Many pediatricians screen toddlers for autism, ADHD red flags, and developmental delays during well-child visits. More detailed assessments are often conducted during preschool and early school years, but evaluations can happen at any age when new concerns arise.
Yes. Some conditions, like anxiety, depression, and certain learning disabilities, may become more obvious as academic and social demands increase. Ongoing monitoring by therapists and parents is important so that emerging conditions can be identified and addressed promptly.
