The gut-brain axis is the two-way communication system between your digestive tract and your brain. It runs on nerves, neurotransmitters, immune signals, and microbial chemistry, and it's a large part of the reason why so many neurodivergent people have persistent stomach problems which are often not even connected to their neurodivergence.
ADHD speech difficulties are usually about effort and disorganisation rather than a complete loss of access. You might notice more grammatical errors, mispronounced words, sentences that lose their thread halfway through, or long pauses while you search for a word you know perfectly well.
Synaptic pruning is the process by which the brain refines its connections during development, removing synapses that are used less frequently while strengthening active ones. In autistic brains, this process works differently — two independent cleanup systems (the neuron's internal recycling programme and the brain's specialised immune cells) are both less aggressive, meaning significantly more connections are retained. This denser wiring contributes to many recognisable autistic experiences: sensory intensity, deep focus, rich pattern recognition, difficulty filtering, and the challenge of switching between tasks or environments.
The mTOR pathway is a signalling system inside every cell that regulates the balance between building new structures and recycling old ones. In autistic brains, this pathway runs hotter than typical, suppressing the cell's internal cleanup processes. Up to 58% of autism-associated genes relate to this pathway, making it a point of convergence where many different genetic routes produce similar outcomes — from differences in synaptic pruning and sensory processing to neuroinflammation and the balance between excitatory and inhibitory brain signalling.
Rejection Sensitivity Dysphoria (RSD) is an intense emotional and physical response to perceived rejection, criticism, or the fear of falling short — experienced by many neurodivergent people. The hot flash of shame, the spiral of "what did I do wrong," the doomsday scenarios building while the other person is simply answering their front door — these are recognisable experiences for many people who grew up having their authentic selves ignored, dismissed, or misunderstood. RSD is a pattern recognition system shaped by real history, and having language for it means you can begin to watch the reaction rather than be yanked along by it.
A verbal shutdown might appear to be “nothing” from the outside, but actually, a lot is going on beneath the surface. Language, speech, even just on the technical side, are very complicated, even before you start adding the social layers on top of it (word choices, cadence, implications of tone of voice, non-verbal communication aspects). …
Sensory processing difficulties are a group of traits associated with neurodivergence. They're part of the wider group of sensory processing differences, meaning all the ways neurodivergent brains handle sensory information differently from neurotypical peers. Any of the brain's 8 sensory processing systems can be affected by processing difficulties.
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.
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.
ADHD paralysis is a form of executive dysfunction.
It refers to the difficulty in initiating, continuing, or completing tasks, even when the person understands the urgency and importance, and also has the ability to do the task. ADHD paralysis can be triggered by various factors, including overwhelm, anxiety, or the perceived complexity of a task.
Interoception is the ability to notice and identify feelings inside one's body, like thirst or hunger. It also includes the ability to notice and regulate temperature changes or notice pain.
Alexithymia is the inability to assign names to feelings, describe them to others or talk about them. It is considered a separate neuropsychological condition but has significant overlaps with autism.
Autistic burnout refers to a state of physical, mental, and emotional exhaustion experienced by autistic people. It is a result of prolonged exposure to overwhelming sensory, social, and cognitive demands, often in an environment that does not accommodate their needs.
Misophonia is a neurodivergent condition characterized by an intense emotional and physiological response to specific sounds. People with misophonia experience strong negative reactions, such as anger, anxiety, or disgust, when exposed to certain sounds. These sounds can vary from person to person but commonly include chewing, slurping, tapping, or repetitive noises.
The dopamine system is the network of neurons, pathways, and chemical machinery that produces, delivers, uses, and recycles dopamine throughout the brain. It's one of the most-discussed systems in ADHD, and with good reason — differences in how this system works are closely linked to difficulties with motivation, attention, reward, and the ability to sustain effort on tasks that aren't immediately interesting.
Sensory avoiding, also known as sensory under-responsivity, refers to a pattern of behaviour where individuals actively try to avoid or minimise 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 crowded …
Sensory Processing Disorder (SPD) is a potential grouping of sensory processing difficulties. As individual sensory processing difficulties are spread across a wide range of diagnoses, SPD is often used as a shorthand to describe significant neurodivergence-related sensory issues that are persistent in a person's life and limit their participation in everyday life, regardless of what diagnosis they would officially belong to.
PMDD is Premenstrual Disphoric Disorder, and refers to a severe, disabling form of PMS.
Masking is a partly unconscious effort to hide or suppress the manifestations of your neurodivergence. It is an exhausting process that many of us do to "fit in" more. Many people start to mask to avoid abuse, discrimination, bullying, harm and ableism.
A feeling of immense distress, a sensory overwhelm / autistic overwhelm is a strong reaction to stimuli 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.
