There are three levels of autism. Level 1 is considered more high functioning and independent, level 3 is the most debilitating form of the disorder, and level 2 is somewhere in between. Some symptoms of autism are common to all levels, while others are typically only present in people with severe autism.
ASD Level 3 – On the most severe end of the spectrum is Level 3 which requires very substantial support. Signs associated with both Level 1 and Level 2 are still present but are far more severe and accompanied by other complications as well.
The Three Levels of Autism
They are usually able to gain some independence. Individuals diagnosed with Level 2 autism have verbal, social, and behavioral deficits. Even with supports in place, they might struggle with these behaviors. Level 3 autism is the most severe and lowest functioning category.
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.
In fact, research has shown that autism symptoms tend to peak around the ages of 2-3 years old. During this time, children with autism may struggle with language development, social interaction, and behavior. They may have difficulty communicating their needs and understanding the needs of others.
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.
Sensory Issues
Many people with autism experience sensory processing disorder. This is more commonly known as sensory overload. Noise, crowds, bright lights, strong tastes, smells, and being touched can feel unbearable to someone with HFA. This makes going to restaurants, movies, and shopping malls difficult.
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.
The change was made in part because these diagnoses were not consistently applied across the board, according to the APA. Doctors approached each of these diagnoses differently. Rolling the diagnoses into a single category offered a more cohesive approach to treating autism.
Children with autism also tend to be very attached to routines. Unexpected events or sudden changes in plan may cause a lot of stress, leading to a shutdown.
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 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. Around 4 times as many boys have autism as girls. The rate of autism in the U.S. went from 1 in 150 in 2000 to 1 in 100 in 2022.
Savant syndrome is a rare, but extraordinary, condition in which persons with serious mental disabilities, including autistic disorder, have some 'island of genius' which stands in marked, incongruous contrast to overall handicap.
Level 3 ASD, formerly known as low-functioning autism, is the most severe form of autims. People with level 3 autism require very substantial support.
When it comes to Asperger's vs. autism, Asperger's generally features less severe symptoms and more higher functioning.
However, the fitness tests showed that aerobic fitness, flexibility and body mass index of children with autism spectrum disorders was similar to the children without autism. The strength test was the only one that children with autism spectrum disorders did not perform as well in, the study said.
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.
If someone in your family has autism spectrum disorder (ASD), you may be more likely to have a child with ASD. ASD can look very different from person to person, so taking a careful family health history can be important for early diagnosis.
Based on the operationalisation of a previous study, we examined 'slower', 'average', and 'faster' agers (Belsky et al. 2017). More than twice as many people in the high autistic trait group (31.6%) were faster agers, compared to 13.3% of the low trait group (see Supplementary Material, Supplementary Figure 1).
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”.
