Autism is only one of the five PDDs the Pervasive Developmental Disorders. Others are the Rett syndrome, caused by certain gene mutations and found only in girls; childhood disintegrative disorder or Heller s syndrome, the next on the same spectrum of ills, lacks any known cause or cure; while Asperger syndrome and pervasive developmental disorder not otherwise specified, PDD-NOS, are the other two. If you think your child is acting strange, you want to have a doctor check for these disorders before you rule them out.
Perhaps every child born is shy at some point in their lives, and sometimes when they are around strangers, they withdraw and stick only to someone familiar but we all grow out of this; eventually we come of age and we realize that mixing and socializing is inevitable. What makes autism most difficult to bear is that there is no known cure to the syndrome, only treatments and medications. But they help.
Obviously there is something that goes wrong during brain development in an infant to cause the child to have autism. Unfortunately, what it is continues to be an enigma. Researchers know enough to understand that there are genetics involved, and the fact that fewer girls suffer the condition points to something about gender and hormones. It is believed that with more research the answer will pop up someday. And we all wait impatiently
It is not very common to see people with autism show a lot of activity in their daily lives, whether young or old. If you were a specialist or professional, you will observe it in the mirror neuron system of their brain. The neuron system is believed to have the effect of allowing the human brain to understand and learn from mere observation. When there is limited activity there, it follows that there should be limited understanding, all part of the autism spectrum of symptoms.
