ADHD Glossary

The ND Hive Glossary

ADHD in real language.

Clinical terms, common phrases, slang the ADHD community actually uses. Translated into language that makes sense, instead of language that makes you feel broken.

A

Activation (Task Initiation)

Clinical

The ability to start a task. When this is impaired, you’re not avoiding. Your brain literally won’t engage the ignition.

ADHD

Clinical

Attention-Deficit/Hyperactivity Disorder. A neurodevelopmental condition involving differences in dopamine regulation, executive function, and attention control. It’s not a focus problem. It’s a regulation problem.

ADHD Paralysis

Common

That frozen, stuck-on-the-couch state where you want to move but can’t. It’s not laziness. It’s a nervous system shutdown plus overload combo.

B

Body Doubling

Community

Working alongside another person, virtually or physically, to help your brain start and stay on task. External presence equals borrowed regulation.

ADHD Burnout

Clinical

Chronic exhaustion caused by prolonged masking, overcompensating, or pushing past capacity. Feels like your brain just stops cooperating.

C

Cognitive Load

Clinical

The total amount of mental effort being used at one time. ADHD brains hit overload faster because everything requires more effort.

Comorbidity

Clinical

When ADHD exists alongside other conditions like anxiety, depression, or autism. Very common, not the exception.

D

Dopamine

Clinical

A neurotransmitter tied to motivation, reward, and interest. ADHD brains don’t produce or use it efficiently, which is why boring tasks feel physically painful.

Dopamine Seeking

Common

Gravitating toward stimulation (scrolling, snacks, new ideas) to regulate brain chemistry. Not lack of discipline. It’s self-medication.

Decision Fatigue

Clinical

Mental exhaustion from making too many decisions. ADHD brains burn through decision energy faster.

E

Emotional Dysregulation

Clinical

Difficulty managing emotional responses. Fast spikes, intense feelings, slow return to baseline.

Executive Dysfunction

Clinical

Impairment in the brain’s management system (planning, starting, organizing, remembering). This is the core of ADHD, not attention.

F

Focus (Inconsistent Attention)

Clinical

ADHD doesn’t mean no focus. It means inconsistent focus. You can focus deeply, just not when you need to.

H

Hyperfocus

Clinical

Intense, sustained focus on something interesting or stimulating. Time disappears. Basic needs get ignored.

Hypersensitivity

Clinical

Heightened response to stimuli (noise, rejection, stress). Your nervous system is louder.

I

Impulsivity

Clinical

Acting before thinking. Can show up as spending, interrupting, quitting, or reacting emotionally.

Interest-Based Nervous System

Community

ADHD brains run on interest, urgency, novelty, or challenge. Not importance.

M

Masking

Clinical

Hiding ADHD traits to appear “normal.” Costs a ton of energy and often leads to burnout.

Motivation Deficit (Misconception)

Common

What people think ADHD is. Reality: it’s not lack of motivation. It’s lack of access to it.

O

Object Permanence Issues

Community

If it’s out of sight, it’s out of mind. Applies to tasks, people, responsibilities.

Overwhelm

Clinical

Too many inputs, decisions, or demands leading to system shutdown.

P

Procrastination (ADHD Version)

Clinical

Not delay by choice. Delay due to inability to activate.

Processing Speed Variability

Clinical

Sometimes fast, sometimes slow. Not consistent, which confuses everyone including you.

R

Rejection Sensitivity Dysphoria (RSD)

Clinical

Extreme emotional pain from perceived rejection or criticism. Feels immediate, intense, and personal.

S

Sensory Overload

Clinical

Too much sensory input (noise, light, touch) leading to shutdown or irritability.

Stimming

Clinical

Repetitive movements or behaviors that help regulate the nervous system.

T

Time Blindness

Clinical

Difficulty perceiving time accurately. “5 minutes” and “2 hours” feel the same.

Task Switching Difficulty

Clinical

Struggling to move from one task to another. Your brain gets stuck in whatever it’s doing.

W

Working Memory

Clinical

Holding information in your mind short-term. ADHD means things disappear mid-task.
