What Does “Autism Co-occurring Conditions” mean?
When families first receive an diagnóstico de autismo, they often experience a mix of emotions: relief from finally having answers, uncertainty about the future, and an overwhelming desire to know how to support their child in a better way.
Many parents soon find that autism often comes with other conditions. These co-occurring conditions, also called autism comorbid conditions, are common and affect most people with autism.
Why are co-occurring conditions often overlooked in autism? This question usually comes up as families learn more about ASD, and many initially assume that behaviors related to anxiety, attention, mood, or even physical discomfort are part of autism itself.
While research continues to evolve, experts recognize that overlapping symptoms and differences in how children express distress can make other conditions harder to identify.
Understanding why this happens is just the beginning. In this article, we’ll take a closer, caring look at these details to offer clarity and hope as you navigate this complex topic.
What Are the Most Common Medical Issues Linked to Autism?
When discussing autism co-occurring conditions, the medical and psychiatric conditions we see the most fall into one of these categories: mental health, neurological differences, gastrointestinal problems, sleep disturbances, and immune-related issues.
Not every child with autism will have all or any of these conditions. Still, knowing what is common can help families notice when their loved one might need extra support.
1. Autism and ADHD
ADHD is one of the most common co-occurring psychiatric conditions in individuals with autism. Studies show that 30% to 60% of autistic people also meet the criteria for ADHD, according to recent findings in Frontiers in Psychiatry.
Children with both autism and ADHD may:
- Struggle with impulse control
- Exhibit high activity levels or distractibility
- Shift attention quickly
- Have difficulty organizing tasks
Because both autism and ADHD affect executive functioning and emotional regulation, it can be hard for families to tell them apart.
2. Autism and Anxiety
Autism and anxiety is another common pairing. A narrative review published in ResearchGate shows that anxiety disorders are high among children and adolescents with autism, often presenting as excessive fear, avoidance, and heightened distress in response to everyday situations, particularly those involving social demands or unfamiliar experiences.
Anxiety is often missed because it can look like irritability, rigidity, or withdrawal, behaviors already linked to autism.
3. Autism and Depression
Depression is also common in people with autism, especially as they grow older. Social stress, trouble making friends, or feeling alone can raise the risk of depression.
Those with autism and depression may experience:
- Changes in sleep or appetite
- Decreased interest in their preferred activities
- Feelings of hopelessness
- Increased irritability
4. Gastrointestinal (GI) Problems
GI issues such as chronic constipation, diarrhea, stomach pain, and feeding challenges affect up to 70% of children with autism, according to systematic reviews found on the National Library of Medicine.
These symptoms can cause physical discomfort and may sometimes explain changes in behavior.
5. Sleep Disorders
Sleep problems such as insomnia, waking up at night, and irregular sleep patterns are also common. Poor sleep can make daytime behavior worse, shorten attention span, and increase emotional reactions.
Why Autism Co-Occurring Conditions Are Often Overlooked
Even though they are common, the signs of co-occurring conditions in autism are not always easy to spot. Research, including extensive studies from the National Institutes of Health, shows that several factors can make these conditions harder to identify, along with autism.
1. Overlapping Symptoms
Many traits, such as difficulty focusing, emotional outbursts, or repetitive behaviors, can appear in autism as well as in conditions like ADHD, anxiety, or depression. Because these symptoms overlap, it can be challenging to determine whether a behavior is part of autism itself or a sign of another condition. It’s common to miss essential differences, especially without a specialized and careful assessment.
2. Masking or Camouflaging
Some children and adolescents with autism learn to hide their struggles, especially at school or in social environments. They may suppress anxiety, imitate peers, or push themselves to meet expectations, making their emotional distress harder to see. Because of this, parents or caregivers may not notice conditions like anxiety or depression until the child is already overwhelmed.
3. Limited Awareness Among Families and Providers
Families may not always link changes in behavior, sleep, or comfort to possible autism co-occurring conditions. Sometimes, healthcare providers focus mainly on autism traits, especially if those seem to explain a child’s behavior, a situation that can delay further checks or evaluations for other needs.
4. Early Behaviors Are Misinterpreted
People sometimes describe early signs of co-occurring conditions as personality traits. A child might seem “shy,” “hyper,” or “extra sensitive,” but these behaviors could actually be signs of anxiety, attention differences, or physical discomfort. If not noticed and addressed, these signs can become more evident over time.
If a child’s support system misses autism co-occurring conditions, the child may not get the right help for all their needs. The lack of support can affect learning, emotional health, and self-esteem. Finding these conditions early and understanding how they relate to autism can help families get more targeted, supportive care.
How ABA Therapy and Early Intervention Support Autism Co-Occurring Conditions

Although ABA therapy is not a treatment for anxiety, depression, or ADHD directly, evidence-based behavioral approaches can support children in managing many of the challenges associated with autism and co-occurring conditions.
ABA Can Help By:
- Teaching coping skills for anxiety
- Supporting emotional regulation
- Strengthening communication
- Improving daily living skills
- Reducing behaviors that interfere with learning
- Supporting routines that improve sleep or transitions
Early intervention is especially powerful; when children receive structured support early, their long-term outcomes (academic, social, and emotional) improve greatly.
Families can also benefit from guidance on how to support their child’s autism co-occurring conditions at home, from visual schedules to sensory accommodations to positive behavior strategies.
