Characteristics of Autism and the Pervasive Developmental Disorders (PDD) What are the Pervasive Developmental Disorders? The Pervasive Developmental Disorders or Autism Spectrum Disorders (ASD) are a group of developmental disabilities, which according to recent estimates, affect as many as 1 out of every 68 people. The Pervasive Developmental Disorders are also known as the autism-spectrum disorders, and they include Autistic Disorder, Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), Asperger’s Disorder, Rett’s Disorder, and Childhood Disintegrative Disorder.
They affect up to 4-5 times as many boys as girls, occur in all cultures, and are present among all socioeconomic classes. What causes Pervasive Developmental Disorders? Pervasive Developmental Disorders are neurologically-based, medical disorders that are not caused by errors in parenting, a specific environmental toxin, poor prenatal care, etc.

Not to be confused with PDNOS. A pervasive developmental disorder not otherwise specified (PDD-NOS) is one of the three autism spectrum disorders (ASD)[1] and also one of the five disorders classified as a pervasive developmental disorder (PDD).[2] According to the DSM-IV, PDD-NOS is a diagnosis that is used for "severe and pervasive impairment in the development of reciprocal social interaction or verbal and nonverbal communication skills, or when stereotyped behavior, interests, and activities are present, but the criteria are not met for a specific PDD" or for several other disorders.[3] PDD-NOS is often called atypical autism,[4] because the criteria for autistic disorder are not met, for instance because of late age of onset, atypical symptomatology, or subthreshold symptomatology, or all of these.[3] Even though PDD-NOS is considered milder than typical autism, this is not always true.
While some characteristics may be milder, others may be more severe.[5] Diagnosis[edit] The areas of the brain affected by generalised anxiety disorder. Generalized anxiety disorder. Causes[edit] Genetics[edit] Generalized anxiety disorder may be hereditary with it running in families.[9] Genetics seem to play a role in this; those with genetic predisposition are more likely to develop GAD, usually in response to a life stressor.[10] Substance induced[edit] Long-term use of benzodiazepines can worsen underlying anxiety,[11][12] with evidence that reduction of benzodiazepines can lead to a lessening of anxiety symptoms.[13] Similarly, long-term alcohol use is associated with anxiety disorders,[14] with evidence that prolonged abstinence can result in a disappearance of anxiety symptoms.[15] However, it can take up to 2 years for anxiety symptoms to return to baseline in about a quarter of people recovering from alcoholism.[16] Tobacco smoking has been established as a risk factor for developing anxiety disorders.[17] Caffeine[edit] Other[edit] Mechanisms[edit] Amygdala Diagnosis[edit] DSM-IV-TR criteria[edit] D.
