Autism Spectrum Disorder (ASD) is typically diagnosed between 18 months and 3 years of age. However, signs can appear as early as 12 months, and a reliable diagnosis is often possible by age 2. Early detection is critical, as early intervention, especially through therapies like ABA, can significantly improve long-term outcomes.
Doctors monitor developmental milestones during routine checkups. Speech delays, limited eye contact, repetitive behaviors, or lack of interest in social interaction are red flags. If concerns arise, a formal evaluation by a developmental specialist is recommended.
While some children are diagnosed in toddlerhood, others—especially those with milder symptoms—may not receive a diagnosis until they start school, when social and communication challenges become more noticeable.
If you suspect autism in your child, don’t wait. Early screening leads to earlier support.
At True Progress Therapy, we offer early intervention ABA services tailored to your child’s developmental needs and milestones.
