While each profiled cortical region showed changes, the largest changes in RNA levels were in the visual cortex and the parietal cortex, which processes information like touch, pain and temperature. The researchers said this may reflect the sensory hypersensitivity that is frequently reported in people with ASD.
Specifically, in autistic brains there is significantly more folding in the left parietal and temporal lobes as well as in the right frontal and temporal regions. “These alterations are often correlated with modifications in neuronal network connectivity,” Culotta says.
A new study led by UC Davis MIND Institute researchers confirms that brain development in people with autism differs from those with typical neurodevelopment. According to the study published in PNAS, these differences are linked to genes involved in inflammation, immunity response and neural transmissions.
Analytical Thinking: People with an autism spectrum disorder think in a logically consistent way that leads to quick decision making. These thinkers can make decisions without experiencing the framing effect that inhibits most neurotypicals from making decisions without bias.
Many autistic children develop language skills at a different rate and in a different order from typically developing children. This means they might not understand what you say to them or might have difficulty following instructions.
Autistic children are often good at learning by heart (rote memory). Many autistic children can remember large chunks of information, like conversations from movies, words to a song, number plates and so on.
A few different factors converge to explain why autistic people have an “overly full head” and disorganized thoughts, as well as why we may be scatterbrained, quick to lose oversight, and more prone to overstimulation and dysregulation. All these factors are likely caused by overconnectivity in the brain.
For people on the autism spectrum, the world is a bewildering place. With oversensitive sensory systems, they battle to process the maelstrom of information flowing into their brains. Often the result is sensory overload, leading to signature behaviours such as tantrums, anxiety and social withdrawal.
However, brain scans using MRI and other methods do indeed help to recognize targets for the treatment of autism and may even help to diagnose autism in the future.
When children with autism speak they sound different from most people. Their speech usually follows one of several characteristic patterns: Some talk in a flat, toneless voice, others in an exaggerated, hyper way that doesn't match the subject matter.
Individuals with autism exhibit impairments in left hemisphere skills such as social-communication, language, and motor-related symptoms, while appearing relatively intact in right hemisphere functions such as visuospatial skills (11).
Deviant brain growth in autism occurs at the very time when the formation of cerebral circuitry is at its most exuberant and vulnerable stage, and it may signal disruption of this process of circuit formation. The resulting aberrant connectivity and dysfunction may lead to the development of autistic behaviors.
People with autism will often analyze emotions differently and will misinterpret your emotions, which can be confusing. They will take the time to deal with challenges to better manage their understanding of others, while taking advantage of your patience to feel understood by another person.
65% of people with autism spectrum conditions are Extreme Type S. The concept of the Extreme Type E brain has been proposed; however, little research has been conducted on this brain profile.
In some ways Williams syndrome is the opposite of autism. For example, people with Williams syndrome love to talk and tell stories, whereas those with autism usually have language delay and little imagination. Many people with Williams syndrome draw disjointed pictures, some with autism draw pictures in perfect detail.
Abstract Some children with Autism Spectrum Disorders (ASDs) exhibit low mental age (Low-MA), defined here as cognitive functioning below 12 months.
However, autism symptoms can show up later in higher-functioning individuals when they're under more demand or challenge, making an adult autism diagnosis possible. In addition, some adults who were not diagnosed in childhood may be later diagnosed in adulthood.
A routine prenatal ultrasound can identify early signs of autism, study finds. Summary: A routine prenatal ultrasound in the second trimester can identify early signs of Autism Spectrum Disorder (ASD), a new study has found.
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.
Intense interests
Many autistic people have intense and highly-focused interests, often from a fairly young age. These can change over time or be lifelong. It can be art, music, gardening, animals, postcodes or numbers.
Some believe that autistic people aren't interested in romantic relationships or aren't capable of romantic love. However, this is far from the truth. In fact, autistic people can make wonderful partners.
Autistic people may act in a different way to other people
find it hard to understand how other people think or feel. find things like bright lights or loud noises overwhelming, stressful or uncomfortable. get anxious or upset about unfamiliar situations and social events. take longer to understand information.
Each person with autism spectrum disorder is a unique individual; people with ASD differ as much from one another as do all people. Children and adults with ASD may speak or interact with others. They may have good eye contact. They may be verbal or non-verbal.
