Signs and Symptoms of Autism Spectrum Disorders

Español (Spanish)

Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. People with ASD often have problems with social communication and interaction, and restricted or repetitive behaviors or interests. People with ASD may also have different ways of learning, moving, or paying attention. It is important to note that some people without ASD might also have some of these symptoms. But for people with ASD, these characteristics can make life very challenging.

Social Communication and Interaction Skills

Social communication and interaction skills can be challenging for people with ASD.

Examples of social communication and social interaction characteristics related to ASD can include

Avoids or does not keep eye contact
Does not respond to name by 9 months of age
Does not show facial expressions like happy, sad, angry, and surprised by 9 months of age
Does not play simple interactive games like pat-a-cake by 12 months of age
Uses few or no gestures by 12 months of age (for example, does not wave goodbye)
Does not share interests with others by 15 months of age (for example, shows you an object that they like)
Does not point to show you something interesting by 18 months of age
Does not notice when others are hurt or upset by 24 months of age
Does not notice other children and join them in play by 36 months of age
Does not pretend to be something else, like a teacher or superhero, during play by 48 months of age
Does not sing, dance, or act for you by 60 months of age

Restricted or Repetitive Behaviors or Interests

People with ASD have behaviors or interests that can seem unusual. These behaviors or interests set ASD apart from conditions defined by problems with social communication and interaction only.

Examples of restricted or repetitive behaviors and interests related to ASD can include

Lines up toys or other objects and gets upset when order is changed
Repeats words or phrases over and over (called echolalia)
Plays with toys the same way every time
Is focused on parts of objects (for example, wheels)
Gets upset by minor changes
Has obsessive interests
Must follow certain routines
Flaps hands, rocks body, or spins self in circles
Has unusual reactions to the way things sound, smell, taste, look, or feel

Other Characteristics

Most people with ASD have other related characteristics. These might include

Delayed language skills
Delayed movement skills
Delayed cognitive or learning skills
Hyperactive, impulsive, and/or inattentive behavior
Epilepsy or seizure disorder
Unusual eating and sleeping habits
Gastrointestinal issues (for example, constipation)
Unusual mood or emotional reactions
Anxiety, stress, or excessive worry
Lack of fear or more fear than expected

It is important to note that children with ASD may not have all or any of the behaviors listed as examples here.

Autism spectrum disorder (ASD) can look different in different people. It’s a developmental disability that affects the way people communicate, behave, or interact with others.

What Are the Causes of Autism?

Experts don’t fully understand all of the causes of autism spectrum disorder. It seems to be genetic, but things such as parental age and prescription medications taken during pregnancy may be involved.

For instance:

A person is more likely to be on the spectrum if a brother, sister, or parent is. But it doesn’t always run in families.
About 10% of kids with ASD have a form of genetic disorder such as Down syndrome and fragile X syndrome.
A large Danish study found a link between ASD and advanced parental age of either parent.
Women prescribed opioids just before pregnancy are likelier to have a child with ASD.

Some children who are on the spectrum start showing signs as young as a few months old. Others seem to have normal development for the first few months or years of their lives and then they start showing symptoms.

But up to half of parents of children with ASD noticed issues by the time their child reached 12 months, and between 80% and 90% noticed problems by 2 years. Children with ASD will have symptoms throughout their lives, but it’s possible for them to get better as they get older.

The autism spectrum is very wide. Some people might have very noticeable issues, others might not. The common thread is differences in social skills, communication, and behavior compared with people who aren’t on the spectrum.

How Does Autism Affect a Child’s Social Skills?

A child with ASD has a hard time interacting with others. Problems with social skills are some of the most common signs. They might want to have close relationships but not know how.

If your child is on the spectrum, they might show some social symptoms by the time they're 8 to 10 months old, including:

They don't respond to their name by their first birthday.
Playing, sharing, or talking with other people don’t interest them.
They prefer to be alone.
They avoid or reject physical contact, including hugging.
They avoid eye contact.
When they’re upset, they don’t like to be comforted.
They don’t understand emotions -- their own or others’.
They may not stretch out their arms to be picked up or guided with walking.

How Does Autism Affect Communication?

About 40% of kids with autism spectrum disorders don’t talk at all, and between 25% and 30% develop some language skills during infancy but then lose them later. Some children with ASD start talking later in life.

Most have some problems with communication, including:

Delayed speech and language skills
Flat, robotic speaking voice, or singsong voice
Echolalia (repeating the same phrase over and over)
Problems with pronouns (saying “you” instead of “I,” for example)
Not using or rarely using common gestures (pointing or waving), and not responding to them
Inability to stay on topic when talking or answering questions
Not recognizing sarcasm or joking
Trouble expressing needs and emotions
Not getting signals from body language, tone of voice, and expressions

What Are Patterns of Behavior With Autism?

Children with ASD also act in ways that seem unusual or have interests that aren’t typical, including:

Repetitive behaviors like hand-flapping, rocking, jumping, or twirling
Constant moving (pacing) and “hyper” behavior
Fixations on certain activities or objects
Specific routines or rituals (and getting upset when a routine is changed, even slightly)
Extreme sensitivity to touch, light, and sound
Not taking part in “make-believe” play or imitating others’ behaviors
Fussy eating habits
Lack of coordination, clumsiness
Impulsiveness (acting without thinking)
Aggressive behavior, both with self and others
Short attention span

How Can I Spot Signs of Autism?

The earlier treatment for autism spectrum disorder begins, the more likely it is to be effective. That’s why knowing how to identify the signs and symptoms is so important.

Make an appointment with your child’s pediatrician if they don’t meet these specific developmental milestones, or if they meet but lose them later on:

Smiles by 6 months
Imitates facial expressions or sounds by 9 months
Coos or babbles by 12 months
Gestures (points or waves) by 14 months
Speaks with single words by 16 months and uses phrases of two words or more by 24 months
Plays pretend or “make-believe” by 18 months

"Children of the rain". What you need to know about autism

11 April 2019 12:01

Behind the poetic expression "children of the rain" lies the daily feat of people who are faced with a diagnosis of autism. Children who will never be able to perceive themselves as part of the world around them, and parents for whom every day is a series of battles and victories. First, fighting with yourself, accepting and realizing that their child will never be cured, and then fighting the disease for every gesture, every smile, every look and word of the child - small, but such important victories. nine0003

Scientists have not been able to reliably establish the causes of the disease. It is known about the genetic predisposition: signs of autism are more often manifested in people whose family already has an autistic person. Pregnancy in mothers of such children proceeds normally, and the children themselves are often very attractive in appearance - autism, as a rule, does not affect the physical development of the child. However, the development of autism is still in some cases associated with the manifestation of other diseases:

cerebral palsy;
tuberous sclerosis;
impaired fat metabolism (the risk of having a baby with autism is greater in obese women).

All of these conditions can have a bad effect on the brain and, as a result, provoke symptoms of autism. However, what autism is, and what are the causes of its manifestation, is still not completely clear.

Early diagnosis plays an important role in the further development of an autistic child. Autism in children is manifested by certain signs. Early childhood autism is a condition that can manifest itself in children at a very early age - both at 1 year old and at 2 years old. What is autism in a child, and whether this disease occurs, is determined by a specialist. But you can independently figure out what kind of illness a child has and suspect him, based on information about the signs of such a condition. nine0003

Early signs of autism in a child

This syndrome is characterized by 4 main signs. In children with this disease, they can be determined to varying degrees.

Signs of autism in children are as follows:

impaired social interaction;
broken communication;
stereotyped behaviour;
early symptoms of childhood autism in children under 3 years of age.

The first signs of autistic children can be expressed as early as the age of 2 years. Symptoms may be mild when eye-to-eye contact is impaired, or more severe when it is completely absent. As a rule, autism manifests itself very early - even before the age of 1, parents can recognize it. In the first months, such children are less mobile, react inadequately to stimuli from the outside, they have poor facial expressions. nine0003

The child cannot perceive a holistic image of a person who is trying to communicate with him. Even in the photo and video, you can recognize that such a baby's facial expressions do not correspond to the current situation. He does not smile when someone tries to amuse him, but he can laugh when the reason for this is not clear to anyone close to him. The face of such a baby is mask-like, grimaces periodically appear on it.

Baby uses gestures only to indicate needs. As a rule, even in children under one year old, interest is sharply shown if they see an interesting object - the baby laughs, points with a finger, and demonstrates joyful behavior. The first signs in children under 1 year old can be suspected if the child does not behave like this. Symptoms of autism in children under one year old are manifested by the fact that they use a certain gesture, wanting to get something, but do not seek to capture the attention of their parents by including them in their game. nine0003

An autistic person cannot understand other people's emotions. How this symptom manifests itself in a child can be traced already at an early age. If ordinary children have a brain designed in such a way that they can easily determine when they look at other people, they are upset, cheerful or scared, then an autistic person is not capable of this.

The child is not interested in peers. Already at the age of 2, ordinary children strive for company - to play, to get acquainted with their peers. Signs of autism in children of 2 years old are expressed by the fact that such a baby does not participate in games, but plunges into his own world. Those who want to know how to recognize a child 2 years old and older should simply look at the company of children: an autist is always alone and does not pay attention to others or perceives them as inanimate objects. nine0003

It is difficult for a child to play with imagination and social roles. Children 3 years old and even younger play, fantasizing and inventing role-playing games. In autistics, symptoms at 3 years old may be expressed by the fact that they do not understand what a social role in the game is, and do not perceive toys as integral objects. For example, signs of autism in a child of 3 years old can be expressed by the fact that the baby spins the wheel of a car for hours or repeats other actions.

Child does not respond to emotions and communication from parents. Previously, it was believed that such children are not emotionally attached to their parents at all. But now scientists have proven that when a mother leaves, such a child at 4 years old and even earlier shows anxiety. If family members are around, he looks less obsessed. However, in autism, signs in children of 4 years old are expressed by a lack of reaction to the fact that parents are absent. The autist shows anxiety, but he does not try to return his parents. nine0003

In children under 5 years of age and later, there is a delay in speech or its complete absence (mutism). The speech is incoherent, the child repeats the same phrases, devoid of meaning, speaks of himself in the third person. He does not respond to other people's speech either. When the “age of questions” comes, parents will not hear them from the baby, and if they do, then these questions will be monotonous and without practical significance.

Stereotyped behavior includes obsession with one activity, repetition of daily rituals, development of fears and obsessions. At the same time, if the sequence of the ritual is violated, the child becomes hysterical or may show aggression or self-aggression. nine0003

Can autism be cured and is it curable at all? Unfortunately, there is no cure. How you can help your child depends on each individual case. Drug treatment is prescribed only in case of destructive behavior of a small patient. But, despite the fact that the disease is not curable, it is possible to correct the situation. The best "treatment" in this case is regular practice every day and the creation of the most favorable environment for the autistic. Classes are held in stages:

To form the skills that are needed for training. If the child does not make contact, gradually establish it, not forgetting who it is - autistics. Gradually it is necessary to develop at least the rudiments of speech. nine0010
Eliminate forms of behavior that are non-constructive: aggression, self-aggression, fears, withdrawing into oneself, etc.
Learn to observe, imitate.
Teaching social games and roles.
Learn to make emotional contact.

The most common treatment for autism is practiced according to the principles of behaviorism (behavioral psychology). One of the subtypes of such therapy is ABA therapy. The basis of this treatment is to observe what the reactions and behavior of the baby look like. After all the features are studied, incentives are selected for a particular autist. Speech therapy practice is obligatory: if the kid regularly works with a speech therapist, his intonation and pronunciation are getting better. At home, parents help the child develop self-service and socialization skills. Since autists have no motivation to play, they get used to the daily routine, everyday affairs, cards are created where the order of performing this or that action is written or drawn. nine0003

Why is early diagnosis important? There are conditions that mimic autism that can be confused with its symptoms. But other methods are used to correct them.

ZPRR with autistic features

The symptoms of this disease are associated with a delay in psychoverbal development. They are in many ways similar to the signs of autism. Starting from a very early age, the baby does not develop in terms of speech in the way that existing norms suggest. In the first months of life, he does not babble, then he does not learn to speak simple words. At 2-3 years old, his vocabulary is very poor. Such children are often poorly developed physically, sometimes hyperactive. The final diagnosis is made by the doctor. It is important to visit a psychiatrist, speech therapist with the child. nine0003

Attention deficit hyperactivity disorder

This condition is also often mistaken for autism. With a lack of attention, children are restless, it is difficult for them to study at school. There are problems with concentration, such children are very mobile. Even in adulthood, echoes of this state remain, because it is difficult for such people to remember information and make decisions. You should try to diagnose this condition as early as possible, practice treatment with psychostimulants and sedative drugs, and visit a psychologist. nine0003

Hearing loss

These are various hearing impairments, both congenital and acquired. Hearing-impaired children also have speech delays. Therefore, such children do not respond well to the name, fulfill requests and may seem naughty. At the same time, parents may suspect autism in children. But a professional psychiatrist will definitely send the baby for an examination of auditory function.

Hearing aid helps solve problems.

Schizophrenia

Autism was previously considered one of the manifestations of schizophrenia in children. However, it is now clear that these are two completely different diseases. Schizophrenia in children begins later - at 5-7 years. The symptoms of this disease appear gradually. Such children have obsessive fears, talk to themselves, later delusions and hallucinations appear. This condition is treated with medication. nine0003

It is important to understand that autism is not a death sentence. Indeed, with proper care, the earliest correction of autism and support from specialists and parents, such a baby can fully live, learn and find happiness, becoming an adult.

Early Childhood Autism Exclusion

July 30, 2018

Voronin Nikolai

Neuropsychologist, Ph. D.

Autism is manifested by the lack of ability to interact with the outside world, communication disorders. nine0003

Most often, childhood autism manifests itself at 2.5-3 years. It is during this period that speech disorders and isolation in children are more pronounced.

However, the first signs of autistic behavior are often seen at an early age, before 1 year of age. It can be difficult for parents to independently distinguish the signs of autism, so it is no coincidence that children at the age of one year are recommended to consult a psychiatrist.

Do not be afraid to consult a psychiatrist! When parents of adolescents with behavioral problems come to us, we most often reveal that in childhood they could have had a developmental distortion of the autistic type, and with timely treatment, difficulties could have been avoided. nine0003

What should parents pay attention to? Symptoms of autism in children.

1. Violations of social contacts and interaction with others

The child practically does not ask to be held, it is more comfortable for him to lie in the crib.
The child does not assume a physiological position when breastfeeding.
The child is inactive, not as lively as peers. nine0003
The child does not respond to new toys, sounds, can stare at one point for a long time.
The child does not respond to his name (usually the first thing parents go to is an audiologist to check their hearing; if everything is fine with hearing, a psychiatrist should be consulted).
When adults or other children try to make contact with the child, he either removes his hands or moves to the side, or reacts aggressively, may throw something, cry. nine0003
The child throws the toy instead of handing it to avoid contact.
As the child grows older, he can go deeper into his inner world; he does not know how and does not want to communicate with family members, rarely seeks help, starts trying to serve himself early, does not use the word “give”, it is easier for him to take it himself or achieve his scandal.
Often children do not respond to discomfort, such as a full diaper; don't cry or draw attention to themselves. nine0003
There is no eye contact, the child does not fix his gaze on objects, toys.

2. Limited interests and features of the game

The child chooses one toy and plays only with it for a long time. Can choose as a toy something that is not intended for the game - ropes, rags.
The stereotypical nature of the game: placing toys in the same order, playing with a certain number of toys, and if one is lost, a scandal can occur. nine0003
Another example - a girl can not play with dolls, like the rest - not to change clothes, not to put her to bed, but simply carry her with her, maximum - iron her.
Games that require fantasy and imagination rarely captivate autistic children.
Children often prefer quieter games (eg puzzles, building blocks).

3. Tendency to repeat actions, the so-called stereotypy

Rocking the whole body from foot to foot, stereotypical head turn, stereotypical shoulder clamping.
Stereotypes observed in speech are called echolalia. It can be manipulations with sounds, words, phrases. At the same time, children constantly repeat words, cliches, cliché phrases that they heard from adults or on TV without realizing their meaning.
Stereotypical games - turning on / off the light, pouring water from glass to glass, pouring sand, cereals. It is difficult for a child to switch from this activity. nine0003
The child gets acquainted with the outside world not through interaction with others, but independently. He can lick, sniff objects.
Clothes: the child chooses certain things and wears only them, the sequence of dressing and undressing may be important for him.
Eating behavior: the child is selective in food, chooses only a certain range of products. In the most severe cases, this may be a complete refusal to eat. In mild cases - rituals: eats food in a certain order, at certain hours. He chooses dishes not by taste, but by shape, by color. Often, for example, a child only eats a certain shape of pasta. nine0003

4. Intellectual disorders

The main feature of the disease is selective intelligence. Autistic people may excel in math, art, and music, but lag far behind in other subjects. Savantism is a phenomenon where an autistic person is very pronouncedly gifted in one specific area. Some autistic people are able to play a tune accurately after hearing it only once, or to calculate the most complex examples in their minds. nine0003

5. Violation of the instinct of self-preservation

Autoaggression occurs in 1/3 of children with autism. Aggression is one of the main forms of response to what is happening, and since children are not inclined to communicate with others, they show this aggression towards themselves (they can beat themselves, bite, bang their heads against the crib).
Very often these children lack a "sense of edge". This can be observed even in early childhood, when the child hangs from the side of the crib, tries to get out of the stroller - the child has no fear. nine0003
Can run far from parents without looking back. If parents specifically hide in order to test the reaction, this reaction is often not.
Can climb a slide on a playground that is too old for him.
What is especially dangerous, children can run out onto the roadway, climb onto the windowsill with the window open.

6. ADHD

More often than other children, autistic children have hyperactive behavior. They are disinhibited and disorganized. Such children are in constant motion, they can hardly stay in one place, they do not respond to requests during classes, there are difficulties in controlling movements (“like on hinges”).

7. Verbal communication disorders

Speech disorders occur in all forms of autism. Speech may develop with a delay or not develop at all. Also, at the initial stages of development, speech may appear earlier than among peers, but at 1.5-2 years there is a regression - the child stops talking to others, but at the same time can fully speak to himself. nine0003
A peculiar intonation with a predominance of high tones at the end of a sentence, or the so-called "bird speech" or its own language, when the child talks to himself "under his breath."
Often children do not talk to others, but speech is present in the game. The reason is the unwillingness to interact with the outside world.

With delayed speech development, you can contact a speech pathologist. If a defectologist suspects autistic disorders, he refers to a psychiatrist. The main thing is to contact a specialist, and not be alone with this problem and not wait for everything to normalize by the age of three. It is better to immediately exclude the disease. nine0003

What to pay attention to in kindergarten? (symptoms of early autism in children after 1 year)

Aggression towards others, especially when the child's personal space is violated.
The child plays away from the others.
Children and caregivers complain about the child because he cannot interact with others, his play is destructive, he can interfere with other children's play. nine0003
Compulsive behavior - the intentional performance of actions according to certain rules, even if they go against the generally accepted ones.

Modern methods of diagnosing autism in children

Psychiatric consultation . This is a conversation with parents and observation of the child in free play. The doctor watches how the baby behaves, how it interacts with parents, whether it looks into the eyes, whether it puts objects in its hands, whether it throws it on the floor. If the child speaks, pay attention to speech, intonation, construction of phrases. The doctor carefully collects the history of the life and development of the child, the history of the mother's pregnancy. It is important when he began to utter the first sounds, when he stood up, crawled, began to walk, what was his gait. nine0003
Speech therapist consultation to rule out autistic speech. The doctor determines whether speech delay is related to autism or other disorders. Children with autism have a peculiar development of sound pronunciation, and an experienced speech therapist will immediately distinguish it.
Neuropsychological consultation to identify developmental milestones that the child may have missed.
nine0002 Screening with tests (Autism Diagnosis Scales) :

D. Wexler intelligence test

Tests (cards, tasks for children) aimed at assessing general awareness, stock of knowledge and ideas about the world around them, the ability to assimilate and process information, and cognitive abilities.

Kaufman intelligence test

Tests to determine the strengths and weaknesses of information processing processes: visual and auditory memory, assimilation of instructions, planning a sequence of actions. nine0003

Raven Progressive Matrices

Allows you to determine the level of intellectual development of the child. Each series of tables contains tasks of increasing difficulty. Raven's progressive matrices are designed to determine the level of mental development in primary school children with any level of speech development.

Questionnaires for parents :

Sensorimotor Development Scales (ages 0-5)

To be completed during the conversation with the parents and observation of the child. They allow you to evaluate various aspects of motor and psychological development in accordance with age standards.

Vanderbilt ADHD symptom questionnaire

Allows you to assess the severity of symptoms of hyperactivity, inattention and impulsivity in various areas of the child's life.

nine0008

CARS Autism Rating Scale

One of the most widely used tests for autism symptoms. The scale includes 15 categories.

Tests by defectologist and psychologist :

ADOS

The gold standard for diagnosing autism. Allows in a playful way to determine deviations in the communication skills of the child. The child is offered "communicative provocations" in which an ordinary child behaves in a "normal" way, a child with autism behaves differently. After the observation, a calculation is made of which behavior was more common or "autistic". According to the results of the calculation, a diagnosis is established. nine0003

ADI-r

A detailed survey that provides all the information needed to establish a diagnosis of autism and assess related mental disorders.

PEP scale

Identification of the child's individual characteristics, characteristics of his communication capabilities, cognitive activity, emotional-volitional sphere, working capacity, etc.
