When President Donald Trump publicly declared autism a national emergency, citing Tylenol and leucovorin, the world briefly turned its eyes to a silent epidemic. In Autism, Mr Trump – Beyond Tylenol and Leucovorin: A Guide to a New Understanding, Dr Othmane Boumaalif, physician and father of an autistic child, unveils a groundbreaking vision: autism is not merely genetic or psychiatric—it is a systemic, inflammatory, and mitochondrial disease rooted in immune dysregulation, mitochondrial dysfunction, gut imbalance, and environmental toxicity.Drawing from nine years of clinical experience and global research, Dr Boumaalif reveals how chronic inflammation, microbiome disruption, and cellular “danger responses” shape autistic symptoms—and how targeted, translational medicine can bring real hope.Beyond science, this book is a human journey—from despair to discovery—calling for compassion, scientific honesty, and hope. It challenges old dogmas and builds a bridge between biology and humanity, offering families worldwide a new paradigm: autism can be understood, managed, and, in many cases, improved.
