Difference Between Autism And Down Syndrome
Neurodevelopmental : Disorders like AS & DS that cause Intellectual Disability differ in etiology, signs & symptoms & Neurobehavioral profiles including motor, language, cognitive & social/ adaptive skills. The genetic accident that causes DS gives a fetus 3 copies of Chromosome 21; a fetus with AS may lack a maternal UBE3A gene, have 2 copies of the gene from dad, or only dad's gene is active at Chr.15 q11.2-q13. ...Read more
ASD are a spectrum of disorders of varying degrees that are characterized by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. Autism statistics from the U.S. Centers for Disease Control and Prevention (CDC) identify around 1 in 68 American children as ...Read more
Symptom presentation: This distinction, introduced in the early 1990's, arose because some individuals had major delays in social interactions and language, along with odd behaviors (autism), while others had good language but problems with the other two areas (asperger's). Subsequent research has shown that, controling for intelligence, the main difference is language--a circular process. It may be going away soon. ...Read moreSee 3 more doctor answers
Both are caused by : genetic accidents. Down Syndrome occurs in a fetus with a full or partial extra copy of Chromosome 21, with characteristic features, congenital anomalies, hypotonia & Intellectual Disability. Turner Syndrome occurs in a female fetus with an incomplete or missing X Chromosome, with characteristic features, Non-Verbal Learning Disabilities, short stature & infertility. See each disorder's website ...Read more
Angelman Syndrome = : intellectual disability,puppet-like, jerky movements, hand-flapping, laughter outbursts, sociability, & severe language deficits from lack of maternal genes, 2 sets of paternal genes or only active paternal genes on Chromosome 15q11.2-q13. A few kids with AS lack social communication & reciprocity + their stereotypical movements, warranting additional diagnosis of Autistic Spectrum Disorder. ...Read more
Spectrum disorder: Autism is a spectrum disorder. With the diagnosis of autism being made when symptoms are severe and severely impairing, and asperger's disorder being diagnosed when symptoms are less severe, yet still a cause for significant impairment and/or distress. Symptoms "in-between" mild and severe are sometimes diagnosed as pdd, nos. Isolated, mild autistic symptoms also occur in the "normal" population. ...Read moreSee 1 more doctor answer
None. "Mongoloid" is: considered an ethnically pejorative term & is no longer used to describe the facial features of flat mid-face, flat nasal bridge, epicanthic folds, skin folds of the inner corners of the eyes & up-slanting palpebral fissures or eye openings that are characteristic facial features of people with Down Syndrome but also are seen in many perfectly neurotypical individuals of Asian descent. ...Read moreSee 1 more doctor answer

Mostly language: The major difference between ausitm ANS asperger's is early language development--relatively normal in the latter. So-called high-functioning autism typically means average or above iq, which usually implies fairly good language. Even so, language measures typically most distinguish the two. That's why new criteria being considered will lump everything under autism spectrum disorder. ...Read moreSee 1 more doctor answer
Different chromosome: Fragile x is a condition created when an abnormality in a faulty x chromosome is allowed to interfere with the cells in the body. In females, their other x prevents most problems while males with a y cannot block the abnormality. Down syndrome has a whole or extra piece of a 21 chromosome in every cell which interferes with normal cell function. ...Read more
Descriptors: The diagnosis for all who have lack of theory of mind, qualitative impairments in social communication & reciprocal interaction, & narrow, restricted areas of interest or stereotypical movements is autistic disorder in the dsm-v. Pdd-nos is the dsm-iv term for having some, but not all, symptoms of autism. Broader autism phenotype, not a diagnosis, is having even fewer. Vaccines don't cause autism. ...Read moreSee 1 more doctor answer
Williams/Angelman: Williams show distinct facial features, Cardiovascular abnormalities, Hypercalcemia & Hyperactivity. Angelman show severe intellectual impairments, Seizures, Ataxia, Speech impairment. Both are rare genetic diseases involving Chromosomal abnormalities (Chromosome 15 in Angelman, 7 in Williams). ...Read more
Not much: "autistic disorder"will include as, pdd-nos & autism. Kids with as may sound like " little professors, "talk about favorite topics without conversational give-and-take( pragmatics) and without typical use of tempo, pitch & loudness (prosody). Kids with hfa struggle with language, but may quickly figure out how to make something work by seeing & handling it. Both have "normal" full-scale iq, >70. ...Read moreSee 1 more doctor answer
Type of impairment: This all wil change in 5/13. For the past 14-15 years, asperger's disorder has described people with longstanding poor social skills and odd or unusually intense preoccupations but relatively normal language, wherease autism has notable language impairment as well. Studies have failed to find marked differences other than in language, so new term will be austim spectrum disorder. ...Read moreSee 2 more doctor answers
Stature and heart: Marfans people are tall, skinny, with valve problems, joint instability, but also have aortic problems. Ehlers danlos has hypermobility, subluxations, but also certain types of eds have tissue fragility, spontaneous pneumothorax, joint subluxation, and has difficulty healing. ...Read more
Depends: Some say very little difference, but technically ppl with autism have some history of speech/language delay while ppl with asperger's disorder have no history of such a delay. Typically ppl with autism struggle more with verbal tasks, but may excel with nonverbal/visual tasks. Often ppl w/ aspergers struggle more with visual tasks but have strong verbal skills. This is not always the case though. ...Read moreSee 1 more doctor answer
Variation on a theme: Parkinson's disease (pd) is a neurodegenerative disorder of as yet unknown cause, which has typical symptoms including tremor, stiffness, lack of spontaneous movement (and many others). Parkinsonism is a condition in which some of the factors of true pd are present but atypical factors are also present. Commonest form is drug-induced parkinson-like movement disorder. ...Read more
A neurodevelopmental disorder affecting three areas: abnormal socialization, communication, and restricted interests with repetitive patterns of behavior. It is usually detected in the first two years of life. Cause is unknown but strong evidence points to an interplay between ...Read more
