No, it is not possible to detect autism in a person at the age of one. Autism spectrum disorder (ASD) is a neurological and developmental disorder that typically manifests during early childhood, typically between the ages of two to three. The early signs of autism can be quite subtle, and can be easily mistaken for normal developmental delays. Additionally, the specific symptoms of autism vary greatly from person to person, which can make it difficult to diagnose in young children.
In the past, it was believed that autism could be detected in babies as young as six months old, however, this is not currently accepted by the medical community. Most autism specialists agree that reliable diagnosis is not possible until a child is at least two years old.
To help diagnose autism in young children, doctors may look for signs of language delay, difficulty with social interactions, and repetitive behaviors. For children under the age of two, doctors may also look for signs of sensory sensitivity, such as an aversion to touch, loud noises, or certain textures. Other things that doctors may look for include a lack of eye contact, difficulty following directions, and difficulty making friends.
If a child displays any of these signs, it does not necessarily mean that they have autism. However, if a parent is concerned, it is important to speak to a doctor about the possibility of a diagnosis. Early diagnosis and treatment can make a huge difference in the lives of children with autism, so it is important to be aware of the signs and take action as soon as possible.
