IQ scores are intended to be stable and consistent measures of a person's cognitive abilities, regardless of whether they have ADHD or are medicated. IQ tests are designed to assess general intelligence and are considered relatively immune to short-term changes in cognitive functioning.
If you scored 140 on an IQ test, that score is likely to remain relatively consistent whether you are medicated for ADHD or not. Medication for ADHD primarily helps with managing the symptoms associated with the condition, such as attention, focus, and impulse control, but it does not directly impact one's underlying cognitive abilities as measured by an IQ test.
It's important to remember that an IQ score is just one measure of intelligence and cognitive abilities. People with ADHD can have a wide range of strengths and weaknesses, and an IQ score doesn't capture the full spectrum of a person's abilities or potential.
If you are considering taking medication for ADHD, it's essential to discuss the benefits and potential side effects with your doctor. The decision to take medication should be based on a comprehensive evaluation of your symptoms, needs, and individual circumstances. Remember, medication is just one part of a broader treatment plan, and other strategies, such as behavioral interventions and support, can also be essential components in managing ADHD effectively.
