ADHD is characterized by challenges in sustaining attention, managing impulses, and perceiving time, though individuals can experience hyperfocus on stimulating tasks. A key theory links ADHD to low dopamine levels, which disrupts normal brain network functioning. Prescription stimulants like Ritalin and Adderall help regulate dopamine and are effective when medically supervised. Non-drug approaches include behavioral training, visual focus exercises, and supplements such as omega-3 fatty acids and phosphatidylserine. Lifestyle strategies like limiting smartphone use and incorporating physical movement can also enhance focus. The episode highlights the importance of early intervention in children and emphasizes combining medication with behavioral tools for optimal results.
