The Diagnostic and Statistical Manual (DSM-V) outlines 3 types of ADHD officially, and “unspecified” isn’t one of them.
It sounds like the clinician may have been unsure of the diagnosis — unsure of which type of ADHD to specify, or unsure of ADHD at all. It may be beneficial to seek a specialist for a 2nd opinion.
