How To Find All The Important Details Of Autism Spectrum Disorders That Are Also Known As Pervasive Developmental Disorders?Autism Spectrum Disorders are disturbing. Children between the age of 3 and 10 were studied in 1943 by Dr. Leo Kanner. He observed certain developmental disorders which could not be medically explained. He first coined the label Â'Early Infantile AutismÂ". Another German medic named Dr. Hans Asperger made similar observations on another group of small children. They had the same problems. It came to be known as Asperger Syndrome. They now feature in the DIAGNOSTIC & STAISTICAL MENTAL DISORDERS MANUAL as 2 of the 5 disorders that affect the Pervasive Developmental or Autism Spectrum Disorders or ASD. The signs of the disease, what are the research findings, and is a solution imminent is the issues that are being discussed here. If it is the second child in the family, its unusual behavior would immediately come to the notice of the mother. In certain cases, the infant seems indifferent and unresponsive from the very beginning. A brightly happy toddler can suddenly become withdrawn and glum. The change is so dramatic that the parents cannot ignore the signs. Other symptoms of Autism Spectrum Disorders surface gradually such as the lack of verbal as well nonverbal expressions, lack of interest in immediate surroundings, and lack of response to normal stimuli. Symptoms may also take the form of self-abuse like head-banging or non-stop hand-wash. Repetitive actions or movements like clapping for no rhyme or reason is yet another sign of Autism Spectrum Disorders. Desperate parents often try hard to find the reason. But even doctors are not sure what causes Autism Spectrum Disorders. Researchers have finally been able to identify a number of genes associated with Autism Spectrum Disorders. Irregularities in several sectors of the brain are believed to be associated with autism. Studies have confirmed that children with autism have abnormal levels of serotonin in their brain. Such abnormalities in turn suggest that Autism Spectrum Disorders could result from disruption of normal brain development at the initial stage. Some people have a genetic predisposition towards Autism Spectrum Disorders. In families with one autistic child, the chance of having the second one with the same disorder is around 1 in 20. In most cases, parents of a child with ASD display traits of mild impairments with emotional disorders like manic depression. Heartbroken parents often search of a cure, only to be told that no such thing is yet available. Autism Spectrum Disorders can hit the child hard. But what to do when someone is affected? Though there is no single best treatment for those with Autism Spectrum Disorders, combination of treatments may be tried out. |
