Not the OP commenter, but generally speaking, boys tend to present with more external symptoms that are visible to others - fidgeting, difficulty sitting still, etc. Girls tend to have more internal symptoms like ‘spacing out’ that others can’t see. A diagnosis in kids is often based on observable symptoms and kids aren’t always asked about their invisible symptoms inside their heads, so boys get diagnosed more frequently. The example symptoms only scratch the surface of what ADHD entails, but’s that’s the gist of it.
