2. Definition
Autism spectrum disorder is a condition related to brain development that impacts how a person perceives and socializes with others, causing problems in social interaction and communication.
The disorder also includes limited and repetitive patterns of behavior.

3. What is autism? Very complex, often baffling developmental disability
First described by Leo Kanner in 1943 as early infantile autism
“Auto” – children are “locked within themselves.”
For next 30 years, considered to be an emotional disturbance

4. What is “Spectrum” in autism?
The term "spectrum" in autism spectrum disorder refers to the wide range of symptoms and severity.

5. Age of Emergence
Autism spectrum disorder begins in early childhood and eventually causes problems functioning in society.
Often children show symptoms of autism within the first year.
A small number of children appear to develop normally in the first year, and then go through a period of regression between 18 and 24 months of age when they develop autism symptoms.

6. What are the signs of Autistic Spectrum Disorder?
social communication (including verbal and non-verbal communication, such as body language)
social interaction (difficulty recognizing or understanding other people's emotions and feelings, and expressing their own)
social imagination (difficulty understanding and predicting other people's behavior)

7. Social communication and interaction
Fails to respond to his or her name or appears not to hear you at times
Resists cuddling and holding, and seems to prefer playing alone, retreating into his or her own world
Has poor eye contact and lacks facial expression
Doesn't speak or has delayed speech, or loses previous ability to say words or sentences
Can't start a conversation or keep one going, or only starts one to make requests or label items
Speaks with an abnormal tone or rhythm and may use a singsong voice or robot-like speech
Repeats words or phrases verbatim, but doesn't understand how to use them
Doesn't appear to understand simple questions or directions
Doesn't express emotions or feelings and appears unaware of others' feelings
Doesn't point at or bring objects to share interest
Inappropriately approaches a social interaction by being passive, aggressive or disruptive
Has difficulty recognizing nonverbal cues, such as interpreting other people's facial expressions, body postures or tone of voice

8. Patterns of behavior
Performs repetitive movements, such as rocking, spinning or hand flapping
Performs activities that could cause self-harm, such as biting or head-banging
Develops specific routines or rituals and becomes disturbed at the slightest change
Has problems with coordination or has odd movement patterns, such as clumsiness or walking on toes, and has odd, stiff or exaggerated body language
Is fascinated by details of an object, such as the spinning wheels of a toy car, but doesn't understand the overall purpose or function of the object
Is unusually sensitive to light, sound or touch, yet may be indifferent to pain or temperature
Doesn't engage in imitative or make-believe play
Fixates on an object or activity with abnormal intensity or focus
Has specific food preferences, such as eating only a few foods, or refusing foods with a certain texture

9. Additional Signs Many people with autism have sensory sensitivities.
They experience sensory experiences very strongly so that, for example, bright lights, loud noises, certain smells or tastes, the feel of certain fabrics may all be distressing to them.

10. Causes
Genetics
Environmental factors 

11. 5 Types of Autism Spectrum Disorders

12. Types
Autism spectrum disorder includes conditions that were previously considered separate
Autism
Asperger's syndrome
Childhood disintegrative disorder
An unspecified form of pervasive developmental disorder

13. Asperger's Syndrome
A form of autism where the language aspect is less of a disability.
  People with Asperger's Syndrome often have good language skills, though their communication with other people will still be impaired because they lack social understanding.
Autism (or ASD - Autistic Spectrum Disorder) is a lifelong condition.

14. Asperger’s Disorders Most common type of Autism .
Usually misdiagnosed as Obsessive-Compulsive Disorder (OCD) and Attention-Deficit Disorder (ADD).
Children are unskilled in communication and any type of social interaction.
Carry repetitive motions and are fixated on patterns of all types.
Often clumsy due to their under developed motor skills.
They carry a talent that they focus specifically on and are thought to be very skilled at.
It is claimed that Albert Einstein may have carried this characteristic.

15. Kanner’s Syndrome Known as the “Classic Autistic Disorder.”
Named after Dr. Leo Kanner who described and studied it in the 1930s – 40s.
Carry very limited emotional connection with anyone.
Very routine-based – wants everything to be the same including: clothing, food, music, and TV shows.
Deeply affected by noise, bright lights and smells.
Generally considered to be low-functioning, but how well their mind works is unknown due to their poor social and communication skills.

16. Used to describe children who have most of the same symptoms as classic autism.
They require the same interventions and treatments.
Differences between PDD-NOS and autism are minor. Only doctors and researchers are able to differentiate.

17. Rett’s Syndrome
Rare type of autism and appears to only happen to girls.
First discovered by Dr. Rett.
Patients often have muscle atrophy and carry repetitive hand motions.
Very low-functioning and will require care for most of their lives.
This type of autism has been diagnosed since the 60s, but in the 1990s, the gene that was said to have caused this condition was found.

18. Childhood Disintegrative Disorder
Very rare and strikes children who appear to have normal development from birth.
Changes usually take place between 2-4 years of age.
Do not potty train, will lose the ability to interact with other children and will lose interest in play.
They will regress and eventually lose the motor skills they had once mastered.
Communication skills will disappear and will even stop talking at one point.

19. Risk factors Child's sex Family history Other disorders
Extremely preterm babies 
Parents' ages

20. Child’s Sex
Boys are about four times more likely to develop autism spectrum disorder than girls are.

21. Family history
Families who have one child with autism spectrum disorder have an increased risk of having another child with the disorder. It's also not uncommon for parents or relatives of a child with autism spectrum disorder to have minor problems with social or communication skills themselves or to engage in certain behaviors typical of the disorder.

22. Other disorders
Children with certain medical conditions have a higher than normal risk of autism spectrum disorder or autism-like symptoms.
Examples include fragile X syndrome, an inherited disorder that causes intellectual problems; tuberous sclerosis, a condition in which benign tumors develop in the brain; and Rett syndrome, a genetic condition occurring almost exclusively in girls, which causes slowing of head growth, intellectual disability and loss of purposeful hand use.

23. Extremely preterm babies
Babies born before 26 weeks of gestation may have a greater risk of autism spectrum disorder.

24. Parents' ages
There may be a connection between children born to older parents and autism spectrum disorder, but more research is necessary to establish this link.

25. What might we notice in a child with autism?
They may not speak.
They may not understand what other people say.
They may copy what other people say.
They may only talk about their favourite subject.
They may be very interested in one thing and know a lot about it.
They may not want to take part in games or activities with other people.
They may find group situations, such as assembly, dinner time or playtime, very difficult.
They may prefer to be on their own, at home or at school.
This is a difficult area to describe as many of the signs of autism are also common in non-autistic children.
Many of the signs listed below may also not be seen in an autistic child.
None of these signs alone indicates autism, but if many of them are present in a child we may start to wonder about ASD.
The major sign we see in school is usually that the child frequently becomes distressed or angry in situations where most children react less strongly or cope better.

26. Cont..
They may like to play the same game or do the same thing every day.
They may get upset, angry or withdrawn if routines change or something different happens (such as their teacher being away or coming to school by a different route).
Their reactions to things may be unusual.
They may not understand implicit social rules, such as not standing too close to someone.
They may not have much sense of danger.
They may be very fussy about what they eat and how it is presented.

27. When to see a doctor
Doesn't respond with a smile or happy expression by 6 months
Doesn't mimic sounds or facial expressions by 9 months
Doesn't babble or coo by 12 months
Doesn't gesture — such as point or wave — by 14 months
Doesn't say single words by 16 months
Doesn't play "make-believe" or pretend by 18 months
Doesn't say two-word phrases by 24 months
Loses language skills or social skills at any age

28. Complications
Problems with social interactions, communication and behavior can lead to:
Problems in school and with successful learning
Employment problems
Inability to live independently
Social isolation
Stress within the family
Victimization and being bullied
