There are five major types of autism which include Asperger's syndrome, Rett syndrome, childhood disintegrative disorder, Kanner's syndrome, and pervasive developmental disorder – not otherwise specified.
Individuals with level 3 autism exhibit marked inflexibility of behavior, with extreme difficulty coping with changes to routine. At this level, restrictive or repetitive behaviors interfere with the individual's ability to function.
Children with level 3 autism often find it challenging to develop their communication and social skills. They are likely to be non-verbal and unable to use spoken language when interacting with other people, and may even be unaware there are people around them.
When it comes to Asperger's vs. autism, Asperger's generally features less severe symptoms and more higher functioning.
“High-functioning autism” isn't an official medical term or diagnosis. It's an informal one some people use when they talk about people with autism spectrum disorder , or ASD, who can speak, read, write, and handle basic life skills like eating and getting dressed. They can live independently.
About one in three people with autism has a severe form of the condition.
In conclusion, there are many factors that can make autism worse. Sensory overload, changes in routine, social isolation, co-occurring conditions, and lack of support can all exacerbate the symptoms of autism.
Long-term research that involved following a group of individuals with autism for two decades indicates that the average life expectancy for some autistic people is about 39 years. Furthermore, this population generally succumbed to health complications about 20 years earlier than individuals who do not have autism.
The life expectancy for Level 2 ASD ranges from 50-60 years old. This is slightly lower than Level 1 and the national average. In some studies, the life expectancy is even lower. The factors that can contribute to a shorter life are injuries to self, injuries stemming from unawareness, trauma, and suicide.
Autism Prevalence
31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85). Autism affects all ethnic and socioeconomic groups.
A lot of times kids with severe autism also have problem behaviors and sometimes major problem behaviors including repetitive behaviors, aggression, self-injurious behavior, and property destruction. All of these things rolled into one presents really big challenges, especially as the child grows older.
It's not uncommon for people, particularly adults, to be misdiagnosed with a mental illness before receiving a diagnosis of Autism Spectrum Disorder(ASD). But mental illness and developmental disabilities like autism are not the same things, although many people with autism also have a mental illness.
Although the exact cause of autism is still unknown, there is evidence to suggest that genetics play a significant role. Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Autism is not an illness
It means your brain works in a different way from other people. It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life.
Autism is very distinct from ADHD, but the core symptoms of ADHD-Combined type, i.e., attention deficit, impulsivity, and hyperactivity, would appear to also be features of autism. ASD and ADHD are neurobiological disorders characterized by similar underlying neuropsychological “deficits”.
SUMMERS: Donald Triplett was the first person to be diagnosed with autism. He died last week after a long fight with cancer. He was 89 years old.
The average age at death for individuals with autism was 36 years younger than for the general population, 36 years of age compared with 72. Of the deaths in individuals with autism, 28 percent were attributed to injury, most often by suffocation, followed by asphyxiation, and drowning.
Key Autism Statistics & Facts
In 2023, the CDC reported that around 1 in 36 children in the U.S. is diagnosed with autism. Autism prevalence has increased 178% since 2000. The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France.
But years later, in 2014, a U.S. study found that almost half of the children with ASD had average or above average intelligence, that is, an IQ score above 85. Less than a third of the children with autism had intellectual disability, and 23% had IQ scores in the "borderline range" from 71 to 85.
Untreated autism causes changes in brain function that make it more difficult for the person to control impulsive behavior or think rationally about their actions before they act on them. This can lead to situations where ASD adults are unable to live alone and take care of themselves without assistance.
