Anxiety Disorders

Anxiety is the most common co-occurring condition in autism, affecting 40 to 70 percent of autistic individuals. Social anxiety, generalized anxiety, and OCD all occur at elevated rates. Unpredictable social situations, sensory overload, and difficulty reading cues contribute. Anxiety may present as increased rigidity, avoidance, or meltdowns rather than typical worry.

Depression

Depression affects 20 to 40 percent of autistic adults. Social isolation, chronic masking stress, employment difficulties, and awareness of being different contribute. Depression may be harder to recognize because symptoms overlap with autism traits like social withdrawal. Suicidal ideation occurs at elevated rates in autistic adults.

ADHD

ADHD co-occurs with autism in 30 to 60 percent of cases. Since 2013, the DSM-5 allows dual diagnosis. Shared symptoms like executive function challenges and sensory seeking complicate diagnosis. Treatment combines behavioral strategies, environmental modifications, and sometimes medication.

Sleep Disorders

Sleep problems affect 50 to 80 percent of autistic children. Difficulties include falling asleep, staying asleep, and achieving restorative sleep. Melatonin dysregulation, sensory sensitivities, and anxiety contribute. Poor sleep worsens daytime behavior and learning.

Integrated Treatment

Effective treatment addresses autism and co-occurring conditions simultaneously. ABA therapy can incorporate anxiety and depression strategies. Medication may help certain conditions when prescribed by a knowledgeable psychiatrist. Treetop ABA Therapy works with each family’s medical team to ensure comprehensive support.
