Why you keep bringing up the same topics

Ajouté : 2026-05-18

[00:00:00]Sometimes when I'm talking to someone, I will bring up the same topic over and over and over again. Now, the name for this is perseveration, and it's one of the most misread behaviors in neurodivergent people. Perseveration refers to the repetition of a particular behavior, thought, or activity, and it continues beyond what the situation calls for. And it shows up differently depending on the person. Now, verbal perseveration involves repeating words, phrases, or topics even after a response has been given or the context has changed. Now, the cognitive version of this involves fixating on specific topics or ideas, often leading to lengthy monologues regardless of the listener's apparent interest.

[00:00:44]Perseveration is not stubbornness, it's not a misbehavior. It helps the person make sense of overwhelming experiences.

[00:00:52]It helps them to manage uncertainty. It also helps with emotional regulation.

[00:00:57]So, there are two overlapping neurological drivers here. The first is executive function, and research suggests that repetitive thinking in neurodivergent people is related to differences in executive functioning, specifically the ability to plan, prioritize, or switch between tasks or topics. Cognitive flexibility is harder when the brain's switching mechanisms don't work the same way. So, we have a harder time letting go of something or moving on. Now, the second is emotional processing, and this involves when something feels unresolved. So, we keep asking, hoping to reach a conclusion, but that conclusion never comes because the issue was meant to be closed by emotional processing and not by thinking. So, us continually asking for more information does not help. And I think this is a big one for me.

[00:01:46]Repetition is not about memory, it's about reassurance. So, some people perseverate because they are still emotionally processing something that feels unfinished, a conflict, a change in plans, a moment that hasn't been fully resolved, and the brain keeps returning to it because it still feels incomplete. And autistic individuals may struggle to shift their thoughts or conversations to a new topic once they've latched onto something. Now, for people with ADHD, we have rejection sensitivity to contend with. So, ADHD-ers may replay conversations obsessively looking for signs of rejection, analyzing every word, tone, or facial expression for confirmation that they said something wrong or weren't understood or caused damage. So, if you're with a neurodivergent person who does this, how can you respond? Do not say, "We already talked about this."

[00:02:37]Something like, "I understand. I heard what you said. You don't need to worry about that part." You're not dismissing the topic, you're landing it. Clear, explicit reassurance helps. It's delivered calmly and without frustration. Honestly, a lot of the time, that's what the nervous system was waiting for in order to move on.
