The term Autism is suggestive of a neural developmental disorder which is an impairment of social engagements, verbal speech and communication which happens without speaking – all happening in a repetitive and restricted behavior displayed by the person. The normal time frame for this type of behavior to appear in a person is usually on or before the person turns three years old. Autism shows up as an affected part of the body through the brain, where communications become construed. This is caused by the way the nerve cells are altered in the brain. Why this happens in Autistic people is not understood well. This is one of three types of Autism, in the ASD spectrum.
Another form of Autism is the cognitive development delay. This also affects spoken language and the third type of Autism is Pervasive Development Disorder. This PDD is given when the criteria for Asperger syndrome or the Full set of criteria for Autism is given and nothing matches.
Autism is created between rare mutations, or so scientists believe. Autism is based on genetics, but it is no clear whether ASD is a combination of common genetic variants mixed with rate mutations or if rare mutations are the sole reason Autism occurs. In less than two percent of all babies born with birth defects, autism has been found. Some say environmental problems such as metal exposure in the air or water could be to blame. Others suggest pesticides inhaled while the mother is pregnant can play a large part in the mutation of genes or still some believe childhood vaccines are responsible. While these are only ideas of some scientists, there still is not enough convincing evidence to prove these cases.
Autism is known to show up four times more often in boys than girls, based on a worldwide populace. Overall the number of people diagnosed with autism has been steadily increasing, nine more children a year have been diagnosed with autism partly due to the changes in diagnostic practices and government-subsidized financial incentives for the named diagnoses, one quest still remains unanswered, that is whether prevalence has increased is still unresolved.
When children are first developing, in their younger stages before the age of two, parents will notice signs that may lead them to believe their child is showing signs of Autism. Autistic signs do not develop quickly; they are a gradual development, with noticeable signs as the child matures. It is hard to pin point when children have Autism, because some develop more normally than others of the same age and then regress. Some signs are linked to early behavioral issues, speech or cognitive learning. Interventions early on can help autistic children gain social, and communicational skills as well as self-care.
Currently there are no known cures for Autism; however there are some reported cases where children have overcome Autism in their lives. When it comes to independence, Autistic children who reach adulthood often do not gain such independence, but some have gone on in their adult lives to be successful. An Autistic culture has begun being formed and many believe Autism is a difference not a disorder.
