How can one control the distractions with adhd?

Meds, effort: The treatment model that appears most helpful uses stimulant medication. It increases the "supervisor" part of the brain to increase vigilance and dismiss distractions before it triggers awareness and response. As the patient ages, they can become more aware of their need to stay focused. Moving away from random childhood reactivity, maturity can help them drop meds in favor of personal effort.

Treatment?: If you are not treated for ADHD, you need to start there and see the results. Beyond effective treatment, controlling one's environment is a necessary but not sufficient condition for controlling distractedness and the other symptoms associate with ADHD. You need a proper evaluation and PROPER treatment first and then need to structure you environment.
