Noisli - Types of neurodiversity

What is Neurodiversity?

Neurodiversity refers to all the different variations in the human brain and the diversity of cognitive functioning in people. Since we are all different, our brains are unique and we’re all equipped with different abilities, skill sets and needs.

The term neurodiversity was first coined by Judy Singer in 1997 and the idea of neurodiversity is to normalize and accept people whose brains function differently. Rather than seeing neurodivergence as a “problem”, neurodiversity embraces all differences and highlights the different ways in which that neurodivergence can be beneficial.

What does it mean to be neurodivergent?

If you’re neurodivergent it means that your cognitive functioning, i.e. how you think, learn and behave is different to neurotypical people.

It’s not a disability but a difference in how the brain works.

Neuro-differences are a social category just like differences in sexual orientation, gender, ethnicity or ability.

Types of Neurodiversity

No brain is wired the same so it is very difficult to put a definite number on how many types of neurodiversity exist. Consider also that people who find themselves in a certain type might still experience things differently.

Let’s have a look at the most common types of neurodiversity:

Autism (ASD)

Defines a broad set of conditions, which is often characterised by repetitive behaviors or patterns and difficulties with social communication. People often have difficulties dealing with other points of view, change or executing mandatory tasks.

Attention Deficit Hyperactivity Disorder (ADHD)

It affects a person’s attention and concentration. People with ADHD often experience difficulty in focusing, following instructions and completing tasks, impulsivity, distractedness and hyperactivity.

Highly Sensitive Person (HSP)

People that are highly sensitive have an increased sensitivity of the central nervous system and have a deeper cognitive processing to emotional, social and physical stimuli, also called Sensory processing sensitivity (SPS). A person with very high SPS has “hypersensitivity” or is defined as a highly sensitive person (HSP).

There are other parts of the autism spectrum such as Asperger’s Syndrome (AS), Attention Deficit Disorder (ADD), Sensory Processing Disorder (SPD), Pervasive Developmental Disorder and Not Otherwise Specified (PDD-NOS).


It’s a reading disorder where people experience difficulties in reading quickly, writing words, spelling, “sounding out” words in the head or pronouncing words.


It characterizes children with a premature ability to read words as well as a fascination with maps, logos, visual patterns or numbers and letters.


People with dysgraphia have their writing abilities affected. It includes difficulties when handwriting, spelling or putting one’s thoughts in writing.


It’s a learning disability in math and people experience difficulties comprehending basic concepts of math, recognizing numbers or learning to count.


Is a condition that affects how the mind processes actions such as coordination and movement.


This is most commonly called stuttering or stammering and is characterized by people involuntarily repeating sounds or syllables as well as the blocking of words, syllables or sounds.

Learning disabilities

People with learning disabilities or intellectual disabilities (ID) experience difficulties when it comes to intellectual and adaptive functioning. This includes conceptual, practical and social skills to do everyday tasks as well as difficulties in problem-solving, planning, judgement, reasoning or abstract thinking.

Tourette syndrome

People with Tourette syndrome manifest tics such as involuntary, repetitive movements and vocalizations.

Obsessive-Compulsive disorder (OCD)

People with OCD often have obsessive thoughts and compulsive behaviors. Such obsessions are urges that evoke feelings of discomfort, disgust or anxiety and persistent unwanted thoughts or mental images.


People with synesthesia experience something with two senses simultaneously. It associates objects like shapes, names or letters with smell, colour or flavour.

Please note that these names often contain words such as “disorder” or “condition” or “disease”, however, an increasing number of proponents of neurodiversity strive to change the language and fight for acknowledging new types of autonomy and giving more control whether there should be any treatment at all.
