It should be remembered that autism is known to be a condition. It is not a disease that can be passed on from one person to another. Over the past years, more and more children are being diagnosed to have different spectrums of autism. Some can be diagnosed even when they are just two years of age.
Usually, some signs of autism will show through the behavior of people and their mannerisms. Some may have some problems with language comprehension. Those who are able to speak may convey their words in a monotonous manner. Poor eye contact is another sign of autism.
