This article will describe autism spectrum disorder in depth, discuss the symptoms of autism in babies and toddlers and explain the advantages of early intervention.

What is Autism Spectrum Disorder?

Autism Spectrum Disorder is a neurological condition that affects the brain and how the individual perceives the world and socializes with others.

A child with autism might depict the following difficulties in communication.

Instances when signs of autism overlap with other conditions

It is not uncommon to assume another condition with autism because of the similarities in the symptoms. In other extreme cases, some children might have a combination of ASD and other developmental conditions. For instance, you could mistake an isolated speech delay for autism. Limited facial expressions, eye contact, and disinterest in communication are common tell-tale signs of isolated speech delay in toddlers and children. Therefore, healthcare providers ought to determine whether the child is experiencing a social delay so they can rule out ASD. Specialists believe that both genetic and non-genetic factors could result in the development of autism. However, suppose you think your child’s diagnosis was due to prenatal exposure to Tylenol. In that case, you could contact a Tylenol autism lawyer to fight for your rights and help you get compensation.

Advantages of early intervention

Early intervention in infancy and toddlerhood helps the child gain more skills to navigate the life that awaits them. Not waiting too long to diagnose autism will help family members understand the condition and provide the help and care the child needs. However, it is never too late to diagnose autism and start corrective action.
