Glossary

Welcome to the Glossary! Here you can find the common words used in the Neurodiversity Movement. You can also find their definitions and origins. This entire section is in Plain Language. The words are in alphabetical order. 

A

ABA

ABA stands for Applied Behavior Analysis. It is a common method of therapy for autistic people.

ABA originated in the 20th century. It was based on B.F. Skinner's radical behaviorism. 

Example: Mark was diagnosed with autism at 3 years old. The people who diagnosed him recommended ABA. His parents enrolled him in a program that is informed by ABA. He attended it 40 hours a week. He learned some important skills liked how to tie his shoes. He also was discouraged from acting autistic. They used skittles as a reward for good behavior. They wouldn't give him skittles if he didn't do what they wanted. He wasn't allowed to eat skittles outside of ABA sessions. Mark used to like skittles. Now he doesn't. Mark doesn't feel in control of his own decisions. He feels like he has to please everyone else before he can please himself. This is because he was in ABA. 

AC

AC stands for "Autistics and Cousins".  This includes autistic people. It also includes people with similar disabilities. The term originated from Autism Network International. Xenia Grant came up with it in 1993.  She did so after meeting someone with hydrocephalus. He was not autistic. however, he was able to relate to autistic people because of his hydrocephalus. He was still accepted in autistic spaces because of this. Online, it evolved to ACs.

Example: Steve has Cerebral Palsy. He is not autistic. His experience of Cerebral Palsy is similar to how many autistic people experience the world. Steve met a group of autistic people. They were able to relate on many things. Because of this, Steve was deemed a cousin. When referring to "ACs", this includes Steve. 

ADHD

ADHD is short for Attention-Deficit Hyperactivity Disorder. There is also Attention Deficit Disorder (ADD). ADHD is a learning disability. It is based in the brain. It is caused by how someone's brain is wired. This makes it a neurotype. Someone with ADHD may have trouble focusing on a single task. Their mind may be occupied with several thoughts at once. ADHD is like autism in many ways. Many people with ADHD are also autistic. Some people with ADHD are not. 

Example: Dwayne has ADHD. This means he has several thoughts at once. This can be hard to keep track of. It can make it easy to forget something. He was talking to a friend about a new movie. Then he suddenly started talking about deep space. He realized he went off topic. He forgot he was originally talking about the movie. Dwayne is currently interested in deep space. He does a lot of research on it and knows a lot about it. The previous month, he was very interested in Dungeons and Dragons. He likes both, but is more interested in deep space this month. It is hard for him to focus on a single task because of his ADHD but he is still very smart. 

Allism

Allism is a term used to describe people who are not autistic. It comes from the prefix of "allo", which means other. It was first used online in 2003. Ettina Shee popularized it. Someone can still have a brain based disability and be allistic. Some like using allistic. Others are critical of its use. Mel Baggs had many criticisms. 

Example: Eva has ADHD but is not autistic. This makes them allistic. 

Tony is neurotypical. This also makes Tony allistic. 

Anti-Vaxxer

An anti-vaxxer is someone who is against the use of vaccines. 

Anti-vaxxers have existed as long as vaccines have. People were unsure of how effective they were. 

Example: Becky has an autistic daughter named Kayleigh. Kayleigh started showing signs of autism when she was 3. This was after Kayleigh had her vaccines. Becky read online that this is why her Kayleigh is autistic. Becky now refuses to give her daughter more vaccines. Kayleigh was autistic before she had her vaccines. Becky no longer trusts the scientists who call vaccines safe. Becky is an anti-vaxxer. 

Terry heard that vaccines cause autism in young children. She decided to wait until her twins, Tony and Trina, were five to give them vaccines. Tony and Trina are not autistic. She is worried about the side effects of the COVID-19 vaccine. Because of this, she is not taking the COVID vaccine and is not giving them to Tony or Trina. Terry takes some vaccines, but refuses others. She also does it on a different schedule than what is recommended. This is based on believing misinformation. Terry is an anti-vaxxer. 

Asperger's

Asperger's Syndrome was a diagnosis like autism. It was on the autism spectrum. It was a different diagnosis than autism. Professionals thought people  with Asperger's were too different to be autistic. The people diagnosing them used the Diagnostic Statistic Manual.  It is also known as the DSM. The newest edition of the DSM no longer includes Asperger's. Asperger's was not different enough from autism to deserve its own diagnosis. So now it is all Autism Spectrum Disorder. 


Example: Carlos has an Asperger's diagnosis. He is autistic. He likes Sonic the Hedgehog. He knows more about Sonic than most people. Carlos also has trouble relating to most people. Carlos is very talkative. He is a full time college student with decent grades. Many people are surprised when he tells them he's autistic.  Carlos struggles with certain subjects. He has a hard time following map directions. There is a lot of food he can't eat. If Carlos got his evaluation today, he would be diagnosed with autism. His diagnosis would be Autism Spectrum Disorder. He got diagnosed with Asperger's because his autistic traits were not obvious. It makes more sense just to call him autistic. This is what he prefers. 

Aspie Supremacy

Autistic people have a range of strengths and weaknesses. Autism is not exactly the same for any two autistic people. 

Mel Baggs coined Aspie Supremacy. Mel also coined autistic supremacy. That is when autistic people consider themselves better than non-autistic people. You can read more from Mel about Aspie Supremacy here and here. 

Example: Dean is autistic. He considers himself an aspie. He got an Asperger's diagnosis. Dean runs a forum for autistic people. He only allows in people he thinks are high functioning. This is Aspie Supremacy. 

Siobhan is autistic. They do not like using aspie. They tell people to listen to nonspeaking autistic people. Someone who is nonspeaking tells Siobhan they did something wrong. Siobhan said something wrong about functioning labels. Siobhan gets mad at this person and blocks them. Siobhan is an aspie supremacist. 

Autism

Autism is a developmental disability. This means it is a disability someone has as soon as they are born. 

Example: 

Both Troy and Sally are autistic. They both have things they really like. Their autism makes them more passionate about their interests. They have different ways of communicating. They have different sensory experiences. Both of them are this way because they are autistic. 

B-D

BCBA

BCBA is short for Board Certified Behavior Analyst. 

Example: Claire is a BCBA. She works at an autism center. Claire writes the plans for kids enrolled at the center.  Her practice is ABA-informed. She believes that behavior is shaped by someone's environment. This means she thinks someone has to encourage or discourage behavior. This is how she thinks people should learn. Claire doesn't think someone's thoughts and feelings are separate from behavior.

Curebie

Curebie is a word for someone who supports curing autism. It applies to non-autistic people and autistic people who want a cure. Curebie was first used in autistic spaces in the early 2000s. People used curebie as early as 2002. 

Example: James thinks autism is a disease. He supports the mission of organizations that want to cure autism. This makes him a curebie.

Double Empathy Problem

The Double Empathy Problem is a term Damian Milton coined in 2011. 

Example: Fred and Latisha are autistic. Latisha notices Fred pacing. Fred does this while thinking. Gary is non-autistic. He thinks Fred is pacing because he is upset. Latisha tells Gary that Fred is fine. Latisha knows this because she also does this. Both Fred and Latisha pace because they are autistic. 

Dyslexia

Dyslexia is a learning disability. It is related to difficulty with reading and writing. 

Example: Asa is Dyslexic. They have a hard time reading. When they read, words appear out of order at first. They are better at listening than reading. Asa prefers audiobooks because of this. 

Dyscalculia

Dyscalculia is a learning disability. It is related to difficulty with reading and writing. It is mainly related to math. Someone with dyscalculia can be good at reading letters but not numbers. They may need more time to complete a math problem than someone without it. 

Example: Matilda has dyscalculia. Numbers appear tilted to her on paper. Matilda can do math problems. She needs more time to finish them. She gets extended time on math tests.

E-H

ECT

ECT is short for electroconvulsive therapy. It is a form of therapy that uses electric shock.

Today, there is a center called the Judge Rotenberg Center. They use shock devices to control behavior. Their devices are called Graduated Electronic Decelerators (GEDs).

Executive Functioning

Someone's executive functioning is how well they can complete daily tasks.

Example: Adam is autistic. Adam decides to spend his day on his favorite Discord server. If he is too focused on using Discord, he may forget to eat dinner. He may also forget to shower. This is because of how his executive functioning works. To make sure this doesn't happen, Adam sets alarms on his phone. Because of this, he knows what time he needs to eat and shower. 

HFA

HFA is short for High Functioning Autistic. Some autistic people call themselves this. Some get called this by other people. People considered high-functioning can speak to communicate. They can pass as non-autistic. It is actually more complicated than this. If someone is considered high-functioning, people may ignore their support needs. Someone may assume they aren't actually needed. 

Example: Imani is autistic. She has a job and pays her own bills. Imani has a Bachelor's Degree. Many people are surprised when they learn she is autistic. They think she is high-functioning. They don't think Imani needs more help than others. Imani can't drive. She uses public transit to get to work. She gets tired quicker than most people. She immediately goes to sleep when she gets home from work. Imani needs a three-day weekend. Her manager won't let her do this. Her manager doesn't think she needs a three-day weekend. This would help Imani. It would make her a better employee. 

Hyperfixation

A hyperfixation is something a person spends a lot of time engaging with. This could be a movie, a game, a book, or even a single person. It is unique for people with cognitive disabilities. If someone has a hyperfixation, they may not talk about much else. Someone can have one or many hyperfixations at once. It can be brief or lifelong. 

The idea of a hyperfixation goes back to the DSM. ADHD and autism have "narrow interests" as a criteria. Autistics and Cousins started to meet each other. They discovered they had a lot of common hyperfixations. They came up with several words to describe them. They all mean the same thing. Many people involved with Autism Network International liked llamas. It was a hyperfixation for them. 

Similar terms: Special interest, hobby, perservation 

Example: Mackenize has ADHD. They have a hyperfixation on Baldur's Gate 3. This is recent. They bought the game last month. They spend a lot of their freetime playing the game. They also like looking at fanart and reading fanfiction for Baldur's Gate 3. They had a hyperfixation on Spider-Man a few months ago. Mackenzie still likes Spider-Man. They are focused on Baldur's Gate right now.

Javonté is autistic. He really likes Mario Kart. He started playing when he was five. This is a long time hyperfixation. He also likes Demon Slayer. This is also a hyperfixation. He started watching Demon Slayer last month. He now owns a Demon Slayer shirt. Javonté wants to buy more Demon Slayer merchandise. He still likes Mario Kart. He plays it once a week. Both of these are hyperfixations.

Hyperlexia

Hyperlexia is when someone can read something very quickly. They may be able to find spelling and grammar mistakes better than most people. Someone who is hyperlexic may start reading at a very young age. If someone is hyperlexic, they may be very interested in letters and numbers.

Example: June is hyperlexic. Xe could read an entire novel at age 4. June reads a lot of books. June can read a whole book in a few hours. Xe may forget to brush xyr teeth because of this. June is happy to be hyperlexic. It can make other parts of life challenging, but it makes other parts easier. 

I-M

Identity-First Language

Identity-First Language is a way of identifying yourself. It is IFL for short. People who prefer IFL call themselves "disabled" instead of "a person with a disability".  

IFL originated in Deaf and Blind communities. They saw their disability as a central part of themselves. In the 1990s, IFL became popular in autistic spaces. Many autistic people see autism as part of who they are. They don't think it is separate. Some may not agree with this. They should respect a person's language preference.

Example: Vincent is autistic. He wants to be called autistic. Vincent does not want to be called a person with autism. 

Hannah is Deaf. She wants people to say she is Deaf. Hannah does not like it when she is called hearing impaired.

Independent Living

Independent Living is the name of a disability sub-movement. It also is an idea. Independent living is different from living in an institution. 

Independent living can mean a lot of things. Those same things may not really be independent. It applies to adults. Kids cannot live independently.

The Independent Living Movement advocates for everyone to live with the ability to make their own choices. 

In the 90s and 2000s, Martijn Dekker had an email list called InLv. This was short for Independent Living on the Autism Spectrum. It was a place autistics and cousins could discuss their lives and get help. The name was comes from the Independent Living Movement. 

Inertia

Inertia comes from physics. It's the idea that an object that is in motion will stay in motion. It is also true for the opposite. If someone is sitting, they will probably keep sitting. It takes more energy to stand up than to keep sitting. Autistic people experience inertia differently from non-autistic people. Inertia is a common topic in autistic spaces. Anna Sullivan did a workshop on it at Autreat 2002. She called it "Inertia: From Theory to Praxis".  

Example: Mikayla found a new series on Netflix. She started watching it. She is now focused on the Netflix show. She has a hard time telling herself to do other things. Mikayla stayed up until 2 am last night. She didn't eat dinner or take a shower.  This is an example of autistic inertia. She was too focused on Netflix to do anything else. If she had someone to remind her eat and shower, it would be helpful. 

Institutions

An institution is a place where lots of people with disabilities live.  

Institutions became a common place to put people with disabilities in the 1800s. 

Intellectual Disability

An intellectual disability is a type of disability someone can have. 

Example: Sasha has an intellectual disability. She needs help getting ready in the morning and for bed at night. She needs help cooking food. She also needs help counting money. Sasha has support people who help her do these things. She decides who her support people are. If Sasha wants to try doing anything on her own, she should be able to. If there is something Sasha does not want to do on her own, she should be able to continue getting help for it. Sasha needs a lot of help with daily living. She still deserves to make decisions about her own life. Everyone should.

LFA

LFA is short for low-functioning autism. It is something people call certain autistic people. Some autistic people identify as this. Most do not. Many people use LFA as a label for something they aren't. People labeled LFA have their talents underestimated. Many people labeled LFA are non-speaking. They may speak a little bit. They use alternative communication most often. They may not be able to pass as non-autistic. People labeled LFA may have intellectual disability. LFA is not a real diagnosis. Functioning labels ignore how complex people are. 

Example: Greg is autistic. They use AAC to communicate. They can sometimes speak. They need some help with daily living skills. They are an excellent writer. They also make great films. They get called LFA because they use AAC. Some autistic people use Greg as an example of someone that they're not like. This ignores the things Greg can do well. Some people online call Greg high-functioning for being able to use the internet. They don't know what Greg needs help with. They don't know what they're good at. They just know what they can see of Greg. 

Monotropism

Monotropism is a theory about how autistic people function. It comes from Dinah Murray and Wenn Lawson. It says that it is easier for autistic people to focus on a single interest at one time rather than several things. 

Example: Tracy's favorite movies are Lord of the Rings and Star Wars. Xe likes other movies. It's hard for xem to give other movies as much focus as LOTR and Star Wars. Tracy participates in online forums for LOTR and Star Wars. Xe cosplays characters from them. Xyr bedroom has stuff from those series. Tracy watched the new Dungeons and Dragons movie. Xe liked it. Xe doesn't get into the same in-depth conversations about it as xe does with Star Wars and LOTR. This is an example of monotropism.

N

Neurodivergent

Neurodivergent is a way to describe how someone is different from other people. Any kind of brain wiring that is different from normal counts as neurodivergent. It includes cognitive disabilities but not only them. It also includes giftedness. Kassiane Asasumasu coined the term in the late 1990s. She meant for it to be all-inclusive. A few other people like Mel Baggs also came up with the word around the same time. Kassiane did the most to define what neurodivergent means. 

Example: Akari is neurodivergent. They are autistic, epileptic, and twice exceptional. Some of those are disabilities, some of them are not. 

Trey has a traumatic brain injury.  He was not born neurodivergent. He acquired it after his brain injury. 

Neurodiverse

Neurodiverse refers to a group of people who all have different types of brains. It is often used instead of neurodivergent. It does not mean the same thing. Neurodiverse was first used in the late 90s in autistic spaces. Neurodivergent came after. People like Mel and Kassiane thought it made more sense.

Example: Bob is neurotypical. Akari is autistic. Trey has a traumatic brain injury. They are a neurodiverse group of people. 

Neurodiversity

Neurodiversity is the diversity of human brains in society. It is short for neurological diversity. 

Example: Pat is pro-neurodiversity. This means she thinks people with cognitive disabilities should have their rights respected. She doesn't think someone is better for not having cognitive disabilities. She thinks everyone deserves equal rights and access to society. Pat doesn't think someone can be too disabled for this. 

Neuroexpansive

Neuroexpansive is a newer term. It is like neurdivergent. 

Example: Brianna is autistic. She calls herself neuroexpansive. It feels more fitting than neurodivergent. 

Neurospicy

Neurospicy is another word for neurodivergent. Its origins are unknown. It likely comes from Tik Tok. 

Example: Ben has ADHD and OCD. He calls himself neurospicy.

O-S

OCD

OCD is short for Obsessive Compulsive Disorder. 

Example: Rebecca has OCD. When she sees the number 4, she has to write to the number 22 in the air. She uses a shortcut by changing 12 to 22 when she gets to 12. If she doesn't do this, she worries she will start acting like she is in the 4th grade again. Rebecca takes medication for OCD. This helps with the compulsions, but it doesn't completely get rid of them.

Ty has OCD. He has to rub his hand against his chin five times. He does this when he has a bad thought. If he doesn't do this, he worries he will have a bad day.

PDD-NOS

PDD-NOS is short for Pervasive Developmental Delay (Not Otherwise Specified). It used to be in the DSM. 

Example: Carl has intense interests. He has a hard time making friends. He flaps his hands. Carl went to see a specialist. The specialist only saw these traits in Carl. The specialist decided he didn't show enough signs of autism to be autistic. She diagnosed Carl with PDD-NOS. Carl is autistic. He didn't get an autism diagnosis for several years. 

Person-First Language

Person-First Language is a way of identifying yourself. It is PFL for short. People who prefer PFL call themselves "a person with a disability" instead of "disabled". 

PFL comes from the Self-Advocacy Movement. The Self-Advocacy Movement started in the 1970s. People with intellectual and developmental disabilities lead the Self-Advocacy movement. Many people with intellectual and developmental disabilities lived in institutions. They didn't like this. Some people with I/DD who left institutions organized to close them. They didn't like people reminding them of their disability. They wanted people to see them as more than their disability. They would often say they were "people first".  People First was the name of their first organization. 

Some people may think their disability is an important part of who they are. They may prefer to call themself disabled. This is fine. Some may not agree with this. They should respect a person's language preference. One person could prefer PFL for one disability and IFL for another. That is also fine.

Example: Maria has an intellectual disability. She wants people to know her as Maria first. She wants people to call her a person with an intellectual disability. She does not want others to call her intellectually disabled. 

Rett Syndrome

Rett Syndrome is a developmental disability. 

Example: Gabrielle has Rett Syndrome. She uses a wheelchair to move. Gabrielle can't speak. She has a hard time moving her hands how she would like to. She uses a tablet to communicate her thoughts. She uses eye gazing technology to select letters. She deserves the same fair treatment everyone else does.

Self-Advocacy

Self-Advocacy is when someone communicates what they want and what they don't want for themself. 

Special Interest

A special interest is something a person is very passionate about. It is similar to a hyperfixation. Special interests can be lifelong. A special interest can be as wide as an entire series or as narrow as a specific character. Someone can have on interest. They can also have many. 

Example: Tyree's special interest is Batman. He's seen all the movies and played all the video games. He collects Batman comics and action figures. He started liking Batman as a kid. He still loves it as an adult. He wants to like Batman for the rest of his life. It is a lifelong special interest. 

Tyree also likes Giraffes. This is more recent. He went to the zoo and saw giraffes. Now he's interested in everything relate to giraffes. He may not have a lifelong interest in giraffes like with Batman. He still loves giraffes.

Spoon Theory

Spoon theory is a common term used in disability communities. It refers to how much energy someone has to give. It measures a person's energy level with spoons. One activity may cost three spoons. Another may cost five. Once someone is out of spoons, that means they drained all their energy. 

Christine Miserando used it in 2003 in an essay called "The Spoon Theory".  It recounts a dinner she had with a friend in college. She asked what it was like to have lupus. Christine got some spoons and used it to describe her experience.  It became popular after she wrote about it in her blog "But You Don't Look Sick". 

Example: Lindsay is autistic and has EDS. It takes more energy for her to do daily tasks than it does for most people. It takes a lot of spoons for her to go to work for a whole day. It takes less spoons for her to work from home. It also takes less spoons for her to watch TV. One day, Lindsay went to work and then to a friend's house after work. Once she came home, she was out of spoons for the day. She watched a few episodes of Breaking Bad and then went straight to sleep.

T-Z

Tourettes

Tourettes is a brain-based disability. 

Example: Vivienne has Tourettes. Their body sometimes twitches. This is hard to control. Many don't notice when it happens. 

Quentin has Tourettes. He sometimes yells "gravy!". This is hard to control. Many notice when it happens. He takes medication for it. He still sometimes yells "gravy!".   

Both Vivienne and Quentin have Tourettes. It is not the same for them. There is a lot they can relate to about it.
