A rumination is a thought or a group of thoughts that get stuck in your head and loop over and over again whether you want it to or not (and you usually don’t). Ruminations get their name from ruminant animals who of animals It can be very difficult to move on from them. Ruminative thoughts often carry some sort of emotion or judgment. Ruminations are usually intrusive (they pop into your head without you consciously thinking of them)

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.

a visualisation of rumination as a person who's head is an eternally repeating train station for a toy freight train that goes round and round on a set of tiny tracks.

Rumination often functions as a desperate attempt to think your way to certainty. For people with a high intolerance of uncertainty, the brain keeps cycling through the same material because it cannot reach the resolution it needs to let the thought go.

Getting stuck in a thought loop is itself a form of cognitive inflexibility. Thinking can’t shift to a new perspective, release the topic, or accept that the issue might not have a clean resolution, so it keeps circling round and round looking for one.

“What’s the difference between verbal shutdown, selective mutism, and being non-speaking?”

Verbal shutdown, selective mutism and being non-speaking are all experiences that involve not speaking, but they work differently, feel different from the inside, and have different causes. Verbal shutdown: temporary loss of speech due to overwhelm Being non-speaking: permanent loss of speech, but not loss of communication Apraxia: loss of speech due to motor planning difficulties in the brain that provide the movements required to form words Selective/situational mutism: an anxiety disorder that results in loss of speech consistently in specific contexts

rigid thinking (cognitive inflexibility)

Cognitive inflexibility, also erroneously referred to as rigid thinking, is a diagnostic characteristic of autism that describes difficulty shifting between tasks, perspectives, or plans. The label captures how the trait looks from outside — but the internal experience is better understood through monotropism: a processing style that goes deep rather than wide. The depth that makes sustained focus, thoroughness, and reliability possible is the same depth that makes switching costly. The difficulty and the strength are the same mechanism.

intolerance of uncertainty

Intolerance of uncertainty (IU) describes the degree to which a nervous system needs predictability in order to function — not as a preference, but as a genuine operational requirement. When outcomes are unknown or plans unconfirmed, a high-IU nervous system tends to generate contingencies: running through variables, gathering information in advance, and finding it difficult to settle until enough is known. For many autistic and ADHD adults, IU runs at a higher baseline than in the general population, and shows up in everyday experiences like needing to know the plan before you can be present, finding plan changes disproportionately disruptive, or preparing carefully for situations in order to free up bandwidth to actually enjoy them. It's not about rigidity or control — it's a nervous system requesting the information it needs to work properly.

restricted repetitive behaviours (RRBs)

Restricted Repetitive Behaviours (RRBs) is the clinical term for a broad group of autistic traits including stimming, echolalia, routines, persistent interests, and sensory sensitivities. Despite the pathologising name, these patterns serve real purposes — self-regulation, cognitive energy conservation, and genuine enjoyment. They are how an autistic nervous system manages a world that doesn't come with enough predictability built in.

Rejection Sensitivity Dysphoria (RSD)

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.
