Autistic disorder:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
A primary characteristic of infantile autistic disorder is unresponsiveness to people. Infants with this disorder won’t cuddle, avoid eye contact and facial expressions, and are indifferent to affection and physical contact. Parents may report that the child becomes rigid or flaccid when held, cries when touched, and shows little or no interest in human contact.
As the infant grows older, his smiling response is delayed or absent. He doesn’t lift his arms in anticipation of being picked up or form an attachment to a specific caregiver. Furthermore, he doesn’t show the anxiety about strangers that’s typical in the 8-month-old infant.
A child who’s autistic fails to learn the usual socialization games (peek-a-boo, pat-a-cake, or bye-bye). He’s likely to relate to others only to fill a physical need and then without eye contact or speech. The end result may be mutual withdrawal between parents and child.
Severe language impairment and lack of imaginative play are characteristic. The child may be mute or may use immature speech patterns. For example, he may use a single word to express a series of activities; he may say “ground” when referring to any step in using a playground slide.
His speech commonly shows echolalia (meaningless repetition of words or phrases addressed to him) and pronoun reversal (“you go walk” when he means, “I want to go for a walk”). When answering a question, he may simply repeat the question to mean yes and remain silent to mean no.
He shows little imagination, seldom acting out adult roles or engaging in fantasy play. In fact, he may insist on lining up an exact number of toys in the same manner over and over or repetitively mimic the actions of someone else.
A child who’s autistic shows characteristically bizarre behavior patterns, such as screaming fits, rituals, rhythmic rocking, arm flapping, crying without tears, and disturbed sleeping and eating patterns. His behavior may be self-destructive (hand biting, eye gouging, hair pulling, or head banging) or self-stimulating (playing with his own saliva, feces, and urine). His bizarre responses to his environment include an extreme compulsion for sameness.
In response to sensory stimuli, he may underreact or overreact and he may ignore objects — dropping those he’s given or not looking at them — or he may become excessively absorbed in them — continually watching the objects or the movement of his own fingers over the objects. He commonly responds to stimuli by head banging, rocking, whirling, and hand flapping. He tends to avoid using sight and hearing to interact with the environment.
A child who’s autistic may exhibit additional behavioral abnormalities, such as:
❑ cognitive impairment (most have an IQ of 35 to 49)
❑ eating, drinking, and sleeping problems, for example, limiting his diet to just a few foods, excessive drinking, or repeatedly waking during the night and rocking
❑ mood disorders, including labile mood, giggling or crying without reason, lack of emotional responses, no fear of real danger but excessive fear of harmless objects, and generalized anxiety.
Autistic disorder:
Signs and symptoms
(Handbook of Diseases)
Typical features of infantile autistic disorder include unresponsiveness to people, language impairment, lack of imaginative play, bizarre behavior patterns, and abnormal reactions to sensory stimuli.
Unresponsiveness to people
Infants with this disorder avoid eye contact, have little or no facial expression, and are indifferent to affection and physical contact. Parents may report that the child becomes rigid or flaccid when held, cries when touched, and shows little or no interest in human contact.
As the infant grows older, his smiling response is delayed or absent. He doesn’t lift his arms in anticipation of being picked up or form an attachment to a specific caregiver. Nor does he show the anxiety about strangers that’s typical in the 8-month-old infant.
The autistic child fails to learn the usual socialization games (peek-a-boo, pat-a-cake, or bye-bye). He’s likely to relate to others only to fill a physical need and then without eye contact or speech. The end result may be mutual withdrawal between parents and child.
Severe language impairment
The child may be mute or may use immature speech patterns. For example, he may use a single word to express a series of activities; he may say “ground” when referring to any step in using a playground slide.
His speech commonly shows echolalia (meaningless repetition of words or phrases addressed to him) and pronoun reversal (“you go walk” when he means “I want to go for a walk”). When answering a question, he may simply repeat the question to mean yes and remain silent to mean no.
Lack of imaginative play
The child shows little imagination, seldom acting out adult roles or engaging in fantasy play. In fact, he may insist on lining up an exact number of toys in the same manner over and over or repetitively mimic the actions of someone else.
Bizarre behavior
The autistic child shows characteristically bizarre behavior patterns, such as screaming fits, rituals, rhythmic rocking, arm flapping, crying without tears, and disturbed sleeping and eating patterns. His behavior may be self-destructive (hand biting, eye gouging, hair pulling, or head banging) or self-stimulating (playing with his own saliva, stool, and urine).
His bizarre responses to his environment include an extreme compulsion for sameness.
Abnormal response
to sensory stimuli
The autistic child may underreact or overreact to sensory stimuli; he may ignore objects — dropping those he’s given or not looking at them — or he may become excessively absorbed in them — continually watching the objects or the movement of his own fingers over the objects. He commonly responds to stimuli by head banging, rocking, whirling, and hand flapping. He tends to avoid using sight and hearing to interact with the environment.
Other behavioral abnormalities
Other characteristics of an autistic child include:
