The more severe the symptoms are, the more affected are the speaking skills. Many people with autism do not speak at all or only repeat words they hear. The speech of a person with autism may sound more formal compared to others’ speech.
People with ASD like predictability and routine; going through the same motions repeatedly is quite a part of their lives like drawing the same picture again and again.
A person with autism is much less adaptable to changes than others; any child would not mind brushing his teeth first then taking a bath or vice versa, but a child with autism finds any change in the routine very upsetting.
Some people think that helping a child with ASD learn to be more adaptable is a good thing; however, this could negatively affect their quality of life. While a child without ASD develops in many areas harmoniously, this is not the case for a child with autism whose cognitive skills may develop at a fast rate, while his social and language skills remain behind. On the other hand, his language skills may develop fast but not his motor skills and of course his social skills.
Moreover, the learning ability of a child with autism can be unpredictable; he can learn something faster than other children like learning to read long words, but later on he forgets them completely.
Tics are not uncommon for people with autism; these tics can go for a long time and can be very complicated. Some people with autism can control them when they happen, but others cannot. Finally, it is important to understand that a person with autism cannot express his feelings in the same way others do, but this does not mean at all he does not have feelings; he can feel pain, love, sadness and happiness like everyone else.
