neurodiversity
The word neurodiversity is used to describe a diverse group of individuals with different neurotypes. It includes all humans, though colloquially it is often used for a group of neurodivergent people.

neurospicy
An informal and tongue-in-cheek term for neurodivergence, often used in a funny way.
neurotransmitter
Neurotransmitters are chemicals that help brain cells “talk” to each other, controlling thoughts and feelings. Dopamine, serotonin and norepinephrine are all neurotransmitters.
neurotypical
A neurotypical person is someone without neurodivergent conditions. A neurotypical solution is one made for neurotypical people.
norepinephrine
Also known as noradrenaline – a neurotransmitter involved in alertness, attention, and response to stress.
object constancy
Object constancy is the notion that you remain connected and aware of items or people even when they are not visible or physically around. Difficulties in object constancy lead to the "out of sight, out of mind" experience, which is very common with ADHD folk. Not to be confused with object permanence, which is a developmental stage in babies, and relates to them believing things genuinely stop existing when not in sight.
palilalia
Palilalia is a form of verbal expression where someone involuntarily repeats their own words or phrases, often with decreasing volume. This natural pattern can help with language processing and self-regulation, particularly during times of stress or when processing complex information.
penguin pebbling
Penguin pebbling is a term derived from the behaviour of Adélie penguins who meticulously collect and arrange pebbles to build their nests.
In a neurodivergent context, the expression is used to describe a common neurodivergent behaviour of people collecting and giving loved items to others - "this made me think of you, I think you'll like this, I thought this was pretty and I want you to have it".
PMDD
PMDD is Premenstrual Disphoric Disorder, and refers to a severe, disabling form of PMS.
restriction
Restriction means being prevented from moving freely or being confined against your will. It can include being held down, trapped, or having your movement controlled by others. This is particularly important for neurodivergent people, who have historically faced harmful practices where restriction was used to stop stimming, force compliance, or 'manage' sensory overload.
rumination
Ruminations are thought loops that you seemingly can’t get out of. Examples: thinking about what you should’ve said 5 years ago, feeling anxious if they misunderstood you, or worrying about whether you should’ve behaved differently, did they judge you, whether you were in the wrong, etc. Can be present in both OCD or ADHD.
scripting
Scripting is a communication pattern where individuals use memorized or prepared phrases in their interactions. Common in autism, it serves as a valuable tool for managing social situations, expressing needs, and conserving energy while communicating. Scripting can be prepared ahead of time or drawn from previously heard phrases, and helps many autistic people communicate more effectively and authentically.
sensory avoiding
Sensory avoiding, also known as sensory under responsivity, refers to a pattern of behaviour where individuals actively try to avoid or minimize exposure to sensory stimuli. These individuals may have a heightened sensitivity to sensory input and may find certain sensations overwhelming or discomforting. As a result, they may engage in behaviours such as avoiding …
sensory overwhelm
A feeling of immense distress, a sensory overwhelm / autistic overwhelm is a strong reaction caused by the compounded effects of stress, exhaustion, lack of safety, a sense of danger, unmet needs, too much information, noise, sights or sounds, smells or touch.
Sensory Processing Disorder (SPD)
Sensory Processing Disorder (SPD) is a neurological condition that affects the way an individual's brain processes and responds to sensory information from their environment.
sensory-seeking
Sensory-seeking refers to a behavioural pattern or tendency in individuals where they actively seek out and engage in sensory experiences or stimuli. Individuals may have a heightened desire for sensory input and actively seek activities or environments that provide intense or stimulating sensations.
serotonin
Serotonin is a neurotransmitter that helps regulate mood, sleep, and appetite, keeping us balanced.
Specific Learning Difficulties
Having a learning difficulty means a person has a harder time learning and acquiring skills. Learning difficulties are not related to levels of intelligence, the related conditions are neurological.
spiritual bypassing
Spiritual bypassing is a dismissive behaviour, meaning the use of spiritual explanations to dismiss, diminish or avoid dealing with complicated emotions, uncomfortable experiences or facing the complex and often harsh realities of life. It's part magical thinking and part toxic positivity.
SSRIs
SSRIs are a type of antidepressant, the name stands for Selective serotonin reuptake inhibitor. They are often successfully used to treat OCD, PMDD, anxiety, PTSD and depression.
stimming
Stimming (also known as self-stimulating) is a common sensory-seeking neurodivergent behaviour. It means stimulating yourself in a repetitive manner to self-soothe, regulate, or express excitement. Stimming is common both in ADHD and autism.
Stimming movements, however, are common in all human beings. Everybody stims, whether it's chewing the end of a pencil while you think, swaying back and forth to the rhythm of the music while you're standing in line, or swinging your legs when they can't touch the ground.
stimulus
A stimulus (plural: stimuli) refers to any physical or sensory input from the environment that elicits a response or reaction from someone. It can be any sensory information, such as sound, light, touch, taste, or smell, that triggers a biological or behavioural response. Stimuli can range from simple to complex and can have varying degrees …
time blindness
Time blindness is when it's tough to grasp the passing of time. It usually means you under- or overestimate the time a project will take. It makes it tricky to manage schedules, deadlines, and planning. It can lead to procrastination, forgetfulness, and feeling overwhelmed or rushed.
titration
Titration is when together with your medical professional you trial different types of medications and the doctor then adjusts the dose based on your experience.
transitions
Transitioning, in the context of neurodiversity, refers to the process of moving from one state, activity, or place to another. It involves a shift in attention, focus, and cognitive resources.
For neurodivergent individuals, it may require additional time, support, and strategies to manage effectively.
Transitioning can encompass a wide range of changes, from minor daily shifts like moving from one task to another, to major life changes such as transitioning from school to work or from living at home to independent living.
trauma-informed
A trauma-informed approach is looking out for the needs of the individual with the effect of trauma taken into consideration.
Trauma can have a profound physical, biological, psychological and social effect on a person, and this effect cannot be discounted.
unmasking
Unmasking is when you slowly learn to allow your neurodivergence to present itself and you don't try to hide yourself. However, to unmask is a privilege, as you need a safe space to do it.
verbal shutdown
Verbal shutdown is a temporary inability to produce speech despite having intact language and thoughts - an involuntary neurological response to overwhelm. It's when words exist in one's mind but cannot be physically spoken due to sensory, emotional, or cognitive overload.
Casually and incorrectly it is sometimes also referred to as 'going non-verbal', but this term is not preferred by the non-speaking autistic community.
waiting mode
Waiting mode is a psychological state characterized by heightened anticipation or anxiety while awaiting a specific outcome or event.
In the neurodivergent, especially ADHD community it usually means the period before an event that needs focus or attention spent in a sort of paralysing waiting mode, not being able to do little else until the event is over.
working memory
Working memory is one of the executive functions. It is our mental scratchpad, where we temporarily hold and play with info to help with tasks like problem-solving and learning. It’s key for everyday stuff but has limited space, so juggling too much can be tough, especially for people with ADHD, who have an even more …
