What is a co-occurring condition?
A co-occurring condition is a medical, developmental, behavioral, or mental health condition that occurs alongside another condition. In autism, some individuals may experience additional conditions that can affect communication, learning, behavior, health, or daily functioning.
Some common co-occurring conditions in autism include:
ADHD– difficulties with attention, impulsivity, and hyperactivity.
Epilepsy – seizures that may occur in some autistic individuals.
Anxiety– excessive worry, fear, or distress that may affect daily activities.
Sleep difficulties – challenges with falling asleep, staying asleep, or maintaining a consistent sleep routine.
Intellectual disability – differences in cognitive functioning and adaptive skills.
Language and communication difficulties – challenges with understanding or expressing language.
Feeding and eating difficulties – restricted food preferences, sensory sensitivities, or challenges around eating.
Sensory processing differences– increased or decreased responses to sounds, textures, lights, smells, or movement.
Gastrointestinal concerns – digestive difficulties that may require medical assessment and support.
Motor difficulties – challenges with coordination, balance, fine motor, or gross motor skills.
Why does this matter?
Autism does not look the same in every individual. When co-occurring conditions are present, they can sometimes influence a person's behavior, learning, communication, and quality of life.
Understanding the whole person—not just the diagnosis—helps families and professionals provide more individualized and effective support.
Early identification, appropriate assessment, and coordinated support can make a meaningful difference.**
