When can autism be detected?

If you want to detect autism, you must judge by some behavioral manifestations of autistic patients in life, such as frequent speech disorders, language ability decline at the age of three or four, not speaking, and always repeating stereotyped behaviors, which are all symptoms of autism.

1. Speech disorder: Most autistic children speak very little or even no words and do not respond when called. Some can make some simple sounds but are unable to complete situational communication. Some children speak in a very low or unclear voice, and only people who are familiar with them can understand them. A small number of children show normal language ability in the early stages, but their language ability declines when they are 3 or 4 years old and they stop speaking.

2. Narrow interests and stereotyped behaviors: Children with this disease can focus on one or several games or activities for a long time, and cannot adapt to changes once they occur. For example, they may be obsessed with spinning on the ground, a TV commercial or the weather forecast, and have no interest in cartoons or TV movies with plots. Some children insist on doing the same thing every day, such as: eating only one or a few dishes, having no interest in other things, insisting on going to school in the same way, and crying and making a fuss if there is any change.

3. Loneliness and isolation: Autistic children like to be alone and have no dependence on their parents. Some children show reactions in infancy, do not like to be held by others, and will cry when held by others. It also manifests itself in a lack of concern for things around him. He does whatever he wants without any scruples, as if no one is around. It seems that whatever happens around him has nothing to do with him, and it is difficult to arouse his interest and attention. He does not make eye contact with others.

4. Intellectual abnormality: About 70% of autistic children have intellectual disabilities, but they may have strong abilities in some aspects. 20% have intelligence within the normal range, and about 10% have supernormal intelligence. Most children have good memory, especially in mechanical memory.
