ADHD medications are generally considered to be effective at reducing the symptoms of ADHD, but less research has been done to measure the real-life impact of medication use on individuals with ADHD. Researchers at the Karolinska Institute in Stockholm, Sweden examined the medical records and test scores of 61 640 individuals with a diagnosis of ADHD between 2006 and 2013 to determine if ADHD medication use leads to higher test scores on post-secondary entrance examinations and published their results in JAMA Psychiatry.
