Aljoša on the Brain Train is a personal hybrid AI documentary exploring neurodiversity through the story of a father and his seven-year-old son, Aljoša — both living with ADHD. With ADHD affecting roughly 2.5% to 6.7% of adults worldwide and around 7.2% to 8.4% of children, this film addresses a global challenge that touches millions of families, yet is still widely misunderstood and stigmatized. By turning the invisible chemistry of a neurodivergent brain into a visual, emotional AI journey, the film helps replace fear, judgment, and stereotypes with clarity, empathy, and understanding.
