Autism spectrum disorders, or ASD, are also called pervasive developmental disorders (PDD) because they involve delay in many areas of development. PDD or ASD is a category that includes five different disorders of development, each with differing severities and patterns: Autistic Disorder.

What is PDD-NOS? PDD-NOS stands for Pervasive Developmental Disorder-Not Otherwise Specified. PDD-NOS was one of several previously separate subtypes of autism that were folded into the single diagnosis of autism spectrum disorder (ASD) with the publication of the DSM-5 diagnostic manual in 2013.

We know that when parents have one child with ASD, their risk of having a second child with ASD is 3-10% (depending on the sex of the child). However, PGD is currently not available to screen for ASD unless the specific genetic cause is known, as may be the case in Fragile X syndrome or chromosomal microdeletions.

Deletions or duplications (eg, 15q duplication) are the most common genetic abnormality associated with PDD/ASD. (See Etiology.) ASD is commonly comorbid with intellectual disability. Fragile X syndrome is the most common genetic cause of intellectual disability.

Fragile X syndrome causes a range of functioning across domains. It is a specific, identifiable condition with a known genetic cause. Autism spectrum disorder is identified by a cluster of symptoms rather than a specific condition, and is believed to have many causes, most of them unknown.

You'll see it referred to as NVLD or NLD. It isn't an official diagnosis like ADHD and autism—in fact many kids who have non-verbal learning challenges have those diagnoses. But experts say focusing on NLD explains what's happening with kids—and how to help them learn—better than those diagnoses.

Asperger's Disorder was added to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) in 1994 as a separate disorder from autism. However, there are still many professionals who consider Asperger's Disorder a less severe form of autism.

Pervasive Developmental Disorder (Not Otherwise Specified) is a form of autism. It is also known as PDD(NOS) or atypical autism. PDD(NOS) is used to describe people who don't fit neatly into one of the specific kinds of autism, such as autistic disorder, Asperger syndrome or childhood disintegrative disorder.

Children with Autism Spectrum Disorder are often restricted, rigid, and even obsessive in their behaviors, activities, and interests. Symptoms may include: Repetitive body movements (hand flapping, rocking, spinning); moving constantly. Obsessive attachment to unusual objects (rubber bands, keys, light switches)

“On the spectrum” usually refers to the specific set of behavioral and developmental problems and the challenges associated with autism spectrum disorder. A diagnosis of ASD means that your child's communication, social, and play skills are affected in some way.

Autism is one of the five pervasive developmental disorders (PDD), which are characterized by widespread abnormalities of social interactions and communication, and severely restricted interests and highly repetitive behavior. These symptoms do not imply sickness, fragility, or emotional disturbance.

EDUCATION & AUTISM SPECTRUM DISORDERS. Sensory processing. Children on the autism spectrum may have trouble understanding or communicating their needs to teachers and fellow students. They can have difficulty understanding some classroom directions and instruction, along with subtle vocal and facial cues of teachers.

There is no question that APD and ADHD can, and often do, co-exist. That is not always the case and audiologists who are involved in the assessment of individuals with APD work to see when they can differentiate between the two disorders.

In the DSM-5, Autistic Disorder, Asperger's Disorder and PDD-NOS are replaced by the diagnosis of Autism Spectrum Disorder.

Brain Wiring Differences between SPD and Autism. Most people know that sensory issues are related to autism spectrum disorders. However, a new study suggests that sensory processing disorder (SPD) is a standalone disorder, separate from autism.

In particular, persistent crying in infants (i.e. excessive crying with late onset and long duration) may be an early symptom of ASD. Key words autism spectrum disorder, gastrointestinal, infant colic.

Restricted behavior and play Children with Autism Spectrum Disorder are often restricted, rigid, and even obsessive in their behaviors, activities, and interests. Symptoms may include: Repetitive body movements (hand flapping, rocking, spinning); moving constantly.
