pervasive developmental disorder symptoms ? pervasive developmental disorder symptom, developmental disorder nos pervasive symptom without. t can be difficult to know at first if a child has a pervasive developmental disorder (PDD). PDDs are a wide spectrum of social and communication disorders, including autism, that can be complicated to diagnose. However, there are acknowledged criteria for determining if a child has a PDD and there are ways to help children with these disorders at an early age. Typically, the symptoms should be recognizable before a child is 3 years old. Although a toddler's behaviors might seem to fit the criteria, they also might just be part of a youngster's developing personality. What Are PDDs? Say a 3-year-old likes to play with the same toy over and over. Pervasive developmental disorder symptoms And maybe he doesn't look at people pervasive developmental disorder symptoms when they talk with him. At preschool, he's just not mixing in with the others. If a child's behaviors seem to interfere with the establishment pervasive developmental disorder symptoms of relationships and communication with others, the child should be evaluated for a language disorder or for possible PDD. PDDs refer to a broader group pervasive developmental disorder symptoms of neurobiological conditions, known as autistic spectrum disorders, that are pervasive developmental disorder symptoms characterized by delayed development of communication and social skills. Perhaps the most pervasive developmental disorder symptoms noticeable feature of a PDD is a problem with communication, including using and understanding language. Children with these disorders can also have trouble relating to others. They may also exhibit unusual play with toys and other objects, including flicking or shaking toys in nontraditional manners, repetitively spinning toys pervasive developmental disorder symptoms or parts of toys, and lining up toys instead of playing with them. Children with a PDD tend to lack curiosity about their environments and have difficulty with changes in routines. It's important to note pervasive developmental disorder symptoms that all children can exhibit unusual behaviors occasionally, pervasive developmental disorder symptoms or they can seem pervasive developmental disorder symptoms shy around others sometimes - without having a PDD. What sets children with PDDs apart is the consistency of their pervasive developmental disorder symptoms unusual behaviors. Symptoms of the disorder have to be present in all settings - not just at home or at school - and over considerable periods of time. With PDD, there's a lack of social interaction, an impairment in nonverbal behaviors, and a failure to develop normal peer relations. A child with a PDD may also ignore facial expressions or may not look at others. Autism is the most well-known PDD. First identified about 50 years ago, autism is estimated to occur in one or two out of every 1,000 people. Approximately 400,000 people in the United States have pervasive developmental disorder symptoms autistic spectrum disorders. Although normal in appearance, children with autism are withdrawn into their own worlds and are unable to relate normally to others. Pervasive developmental disorder symptoms And although most kids with PDD can be drawn out enough to be communicative, children with autism often cannot. Included in the autistic spectrum are Asperger syndrome, which is a high-functioning form of autism in children who generally have high IQs, and childhood disintegrative disorder, in which a child may develop fairly normally until 18 to 36 months and then begin to regress, especially in speech and social interaction. Other PDDs include Rett syndrome and a disorder called PDD-not otherwise specified, or PDD-NOS. All of these conditions, to varying degrees, affect communication skills as well as a child's cognitive skills and behavior.What is known is that PDDs are not caused by what used to be known as "the cold mother" in psychological studies pervasive developmental disorder symptoms (earlier notions that these disorders developed because of the emotional detachment of a child's parents have been debunked). Diagnosing PDDs More recent research suggests that a PDD's onset can be recognized in a child before the age of 3 years. If a child has difficulty with social interaction and communication and exhibits repetitive behavior, often a doctor or specialist will refer to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV), which contains criteria for diagnosing pervasive developmental disorder symptoms PDDs.
