Another symptom is that children with autism can become increasingly sensitive when it comes to senses such as taste, smells, or sounds. This will cause frustration for the child and could cause erratic outbursts. They will also think nothing of harming themselves as in some cases their sensitivity to physical sensations is numbed.
In recent research, it is shown that twenty percent of children with autism suffer negative changes between early child development and abilities that are totally impaired. Knowing the signs of autism will ensure that you are properly educated on the origins as well as treatments and symptoms of autism, which will ultimately prevent your child from regressing should the necessary treatment be administered.
