Charateristics Autism
|
may lack speech altogether or may be delayed in their acquisition and use of language
may repeat words (echolalia) in place of normal verbal communication may recite entire lines of text from books, movies or computer games out of context for no apparent reason may never develop gestures may be no response when the person's name is called. lack of response to verbal requests /impaired comprehension Characteristics of autism often confuse pronouns. unable to interpret facial expressions or emotions. fleeting eye contact, if any at all. difficulty transitioning from one activity to another. lack of interest in socially interactions aloof or indifferent to other people. lack of imaginative play preference to engage in repetitive activities for extended periods of time such as rewinding videos, stacking blocks, or lining up toys May find it difficult or impossible to hold a conversation or may compulsively steer the conversation to one subject. |
|
Autism impairments
|
Autism Spectrum Disorders impair three main areas of human development: speech, communication, and social interaction. These impairments may range from mild to severe.
|
|
down syndrome
|
The most common chromosomal cause of intellectual disability-trisomy 21. Extra chromosome in each cell of the body (47 instead of 46)
Nondisjunction, translocation, mosaicism 1 in 600-800 births (all races affected) Possible Features: mental retardation, heart disease, hypotonia, slant to eyes, short. |
|
down syndrome language
|
*make fewer nonverbal requests before spoken language starts
*spoken language well below CA expectations, often more delayed than other developmental areas *semantics: smaller no. of different words *syntax: few syntactic devices, not able to use mental representations to coordinate ideas with the necessary syntax to express them *likelihood of learning to read is low. Word recognition better than phonological awareness |
|
Nondisjunction DS
|
pair of chromosome one of which did not divide 95%

chromosome 25 replace 15 4%
|
|
Mosaicism

|
abused/neglected brain
|
Poorly integrated cerebral hemisphere-smaller corpus callosum emotion regulation, integrated functioning, and social development Toxic effects of stress hormones (neuroendocrine) on the developing brain-permanent damage to hippocampus (critical for memory)
