Does late diagnosis mean I missed the window where medication helps?

Late diagnosis does not mean, as a rule, that the window where medication can help has closed. NICE NG87 covers adults and does not set an upper age ban on considering ADHD. Age alone is not a closed window in that guidance. FasTreat also offers private online ADHD assessment and ongoing care, depending on your needs and clinical assessment.
