Early Signs of Autism Spectrum Disorder

By Dr. Daniel Robinson, Coastal Pediatrics

Autism is a spectrum of closely related disorders that can cause significant social, communication, and behavioral challenges.

Autism Spectrum Disorder (ASD) appears in infancy and early childhood and the effects can range from special gifts to severe challenges. The signs and symptoms of ASD vary greatly, as do its effects.

Catching autism early – before your child reaches 18 months – can make a huge difference. Early intervention can reduce the disorder’s effects and help a child learn, grow, and thrive.

The American Academy of Pediatrics (AAP) recommends all children be screened for ASD at 18 months and 24 months of age during regular well-child visits.

Monitor your child’s development and look for these early warning signs of autism. If you have any concerns, share them with your pediatrician.

  • Resists cuddling or holding.
