Is autism present with symptoms at birth?

Autism symptoms may not necessarily manifest at birth since autism is not a genetic or congenital disease. Most cases are caused by acquired factors, so symptoms may not appear immediately after birth. Autism typically develops in infancy and usually manifests before age 3. If not treated promptly, it may lead to lifelong symptoms. Autism is a mental disorder characterized primarily by social interaction difficulties, language development impairment, repetitive and stereotyped behaviors, and narrow interests. It is often caused by genetic factors, environmental factors, immune system abnormalities, etc., and is not a congenital disease.

As autism is not a genetic disease, it generally does not cause genetic mutations during onset and is not transmitted to offspring. Even if parents have autism, it will not be passed down to their children. However, if patients with autism do not receive proper treatment or psychotherapy during their developmental period, their condition may worsen, manifesting as social difficulties, language development impairment, repetitive behaviors, and even self-injurious, aggressive, or destructive behaviors.

Patients with autism require psychological assessment scales, as well as brain MRI, EEG, and evoked potential tests. Under the guidance of a doctor, they may be prescribed medications such as risperidone, aripiprazole, and sertraline hydrochloride. Rehabilitation training, including language training, social skills training, and motor training, is also essential to improve language development and promote recovery.
