Meconium is a substance that accumulates in the bowel of the developing fetus and is discharged shortly after birth. Some evidence suggests that the use of medications during pregnancy may be related to the development of autistic symptoms. Expert Lift IQ As newborns, children with autistic behaviors show a higher rate of respiratory illness and anemia than healthy children.Some professionals believe that autistic disorders may be caused by allergies to particular fungi, viral infections, and various foods. No controlled studies have supported these beliefs, but some parents and professionals report improvement when allergens and/or certain foods are eliminated from the diet.Viral infections of the mother, such as rubella, or of the young child, frequently in boys than girls. Several surveys have shown that between two and four percent of siblings of autistic children also have autistic disorder. This rate is 50 times greater than in the general population. Among pairs of identical twins in which one child has autism, in 36% of the pairs, the other twin has autism as well.Among fraternal twins, there is no similar correlation. Some studies indicate that even among family members who are not diagnosed as autistic, there tends to be a higher-than-average rate of language and other cognitive problems. As many as 25% of autistic children develop epileptic seizures later in life, usually during adolescence. This symptom appears mostly in those who are also mentally retarded.Recently, professionals have reported observing increasing numbers of children with autistic disorders. While no studies confirm this observation, there are three possible reasons why it appears so. First, the definition of "autism" and "autistic disorders" has widened considerably since the first case reports by Leo Kanner in 1943. The DSM-IV-TR definition currently in use includes a far greater concerned parents of infants under two years that their children are "normal," or will "grow out of" a disturbing behavior, because many children do. At the time that speech and language usually develop, parents are more likely to observe that their autistic child is not at the same level as other children his age. Once the child is old enough to play with other children, it becomes more apparent that the autistic child either isn't interested in doing so, or does so in strange, unusual ways that differ from most children of the same age. Motor development may also appear unusual, with repetitive motions such as spinning, self-injurious behaviors such as headbanging, and rocking back and forth, giving the parents strong clues that their child behaves differently from others.The child who continues to display unusual behaviors at about the age of two years would most likely receive a referral from the pediatrician to a child psychiatrist or to an early intervention program with a multidisciplinary staff including such as encephalitis, mumps, and measles, occasionally appear to cause autistic disorders. The common childhood immunization series known as MMR (measles, mumps, rubella) has recently come under scrutiny as a possible cause of some autistic conditions.DSM-IV-TR specifies three diagnostic categories, each with four components, that are used to make a diagnosis of autistic disorder. These diagnostic categories include impairments in social interaction, communication, and particular patterns of behavior. More information about the individual diagnostic categories and components follows.
