Autism is a developmental disorder that can affect people of all ages, but it is most commonly diagnosed in early childhood. While the exact cause of autism is still unknown, it is believed that certain genetic, environmental, and medical factors may play a role in its development.
Autism can manifest itself in different ways, depending on the individual and the severity of the disorder. Early signs of autism may include delays in language development, difficulty socializing, and repetitive behaviors. However, these signs may not be readily apparent until the child reaches the age of three or four.
In some cases, autism can be diagnosed at an even earlier age. In fact, the American Academy of Pediatrics recommends screening for autism at 18 and 24 months. During the screening, doctors will look for signs of social and communication impairments, such as lack of eye contact, limited verbal and nonverbal communication, and repetitive behaviors. If a child is found to have signs of autism, further testing may be recommended.
In addition, there are some children who may not show signs of autism until they are older, such as during the elementary school years. This is often referred to as late-onset autism. These children may have above-average language and social skills, but as they reach school age, they may start to struggle with socializing, communicating, and interacting with their peers.
Overall, autism can develop at any age. However, it is most commonly diagnosed in early childhood, and it is important to be aware of the signs and symptoms of autism so that a diagnosis can be made as soon as possible. Early intervention is key to helping children with autism reach their full potential.
