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.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other.
People with the BAP have some traits common to autism spectrum disorder (ASD), but not enough to have the disorder. But it's not comedians who have drawn scientific scrutiny for having the BAP: it's the parents and siblings of people who actually have autism.
Attention Deficit Hyperactive Disorder (ADHD)
There can be overlap in the symptoms of autism and ADHD, difficulty focusing, hyperactivity and impulsivity. But while children with ADHD will resist order and repetition, these things can be comforting for a child with autism.
The principal difference between autism and what was once diagnosed as Asperger's is that the latter features milder symptoms and an absence of language delays. Most children who were previously diagnosed with Asperger's have good language skills but may have difficulty “fitting in” with their peers.
Today, Asperger's syndrome is technically no longer a diagnosis on its own. It is now part of a broader category called autism spectrum disorder (ASD). This group of related disorders shares some symptoms. Even so, lots of people still use the term Asperger's.
It describes a person who may appear to be neurotypical, but is actually autistic or neurodivergent.
Some individuals with borderline autism may be referred to as “high-functioning” autistic. This may because they live independently, function or functioned well at school and/or work, and do not have any observable behaviors such as those exhibited through language or developmental delays.
If you still hear people use some of the older terms, you'll want to know what they mean: Asperger's syndrome. This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life.
Many biological conditions can lead to social difficulties, including autism. However, not all autistic individuals will display social awkwardness (though they may struggle inwardly). Moreover, not everyone who is socially awkward is autistic. And, in fact, they don't necessarily have a diagnosable condition.
Although both OCD and ASD have similar symptoms, they are different conditions. OCD is a mental health disorder, whereas ASD is a developmental condition. ASD is a condition that a person is born with. OCD can develop during a person's lifetime.
Inheritance. ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.
Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
ADNP Syndrome (Helsmoortel-VanDerAa Syndrome/HVDAS)
ADNP is one such rare neurodevelopmental genetic disorder.
Autism as a single primary condition that exists along with numerous distinctly, separate “quasi-autistic” conditions that share some attributes with primary autism, but are not really autism. Autism that can be a primary condition or that may be secondary to some other recognized or unknown condition.
ADNP syndrome is a condition that causes a wide variety of signs and symptoms. Its hallmark features are intellectual disability and autism spectrum disorder, which is characterized by impaired communication and social interaction.
Hyperlexia is advanced and unexpected reading skills and abilities in children way beyond their chronological age. It is a fairly recently named condition (1967) although earlier descriptions of precocious reading do exist.
Low-functioning autism (LFA) is a degree of autism marked by difficulties with social communication and interaction, challenging behavior, and differences in social or emotional reciprocity. Sleep problems, aggression, stereotypical, and self-injurious behavior are also common symptoms.
Level 1 is the mildest, or “highest functioning” form of autism, which includes those who would have previously been diagnosed with Asperger's syndrome. Individuals with ASD level 1 may have difficulty understanding social cues and may struggle to form and maintain personal relationships.
Mild autism is level 1 autism spectrum disorder. It means a person does not have severe symptoms and needs a lower level of support than someone else with autism. People with mild autism still have a hard time communicating and interacting with others.
