Part of the challenge for students with ADHD is managing the steps and focus needed in doing homework and long-term projects. For some students on the Autism Spectrum (and with an ADHD diagnosis as well), a strategy of decreasing stimulus as well as using managed stimulus can help with concentration and perseverance. For many students, environmental noises and sounds distract from the task at hand, thereby lowering a student's ability to initiate and complete school tasks (reading, assignments, essays, etc.). Brown Noise is a tool that might help some students with ASD and ADHD focus on school work as well as relax. It's worth checking out and seeing if you or your child might benefit from it. As always, pay attention to the volume recommended (not too loud!) as well as other recommendations.
