Does ADHD cause “blank mind” moments?

Yes. Many adults with ADHD experience sudden mental blanks where thoughts disappear entirely. This can happen during conversations, tasks, or when put on the spot. It’s often related to cognitive overload, stress, or working memory limits. When the brain is overwhelmed, it can briefly shut down access to information rather than becoming distracted. Clinicians call this a cognitive freeze. It’s not a lack of intelligence or preparation. It’s a temporary processing bottleneck, and it’s very common in ADHD, especially under pressure.
