Autism is a complex neurodevelopmental disorder that is characterized by difficulty with social communication, restrictive and repetitive behaviors, and sensory processing difficulties. While the exact cause of autism is unknown, research points to a combination of genetic and environmental factors.
The question of whether autism is something that a person is born with or if it can develop later in life is one that has been debated for years. While researchers have not identified a single cause of autism, it is generally accepted that it is likely caused by a combination of genetic and environmental factors.
Recent studies have suggested that some cases of autism may be due to genetic mutations or irregularities that are present at birth. For example, some forms of autism are linked to genetic mutations on certain chromosomes, such as chromosome 15. In addition, certain medical conditions, such as fragile X syndrome, can cause autism-like symptoms.
However, it is also possible for autism to develop later in life in response to environmental factors. Exposure to certain toxins or medications during pregnancy, for example, has been linked to an increased risk of autism in children. Furthermore, some research suggests that certain infections, such as the measles-mumps-rubella (MMR) vaccine, may increase the risk of developing autism.
Ultimately, while it is likely that some cases of autism are present at birth due to genetic mutations or irregularities, it is also possible for autism to develop later in life in response to environmental factors. Therefore, it is important to consider both genetic and environmental factors when evaluating a person's risk of developing autism.
