I am based in Cape Town. My son has ADHD and Tourette’s syndrome. We found that neurotherapy (with bio feedback) worked wonders for him. It was quite pricey but absolutely worth it. He attended a 45 minute session once a week for 40 weeks and now visits once every 3 months for a “top” up. The intervention works by adjusting the brain’s “memory” by creating new neural pathways.Find a qualified neurotherapist in your area and possibly give that a shot.
