Every so often, a news story comes along that captures people’s attention, stirs curiosity, and sparks conversation. Recently, CNN featured one such story about a young boy named Mason, his journey with autism, and a decades-old drug called leucovorin that brought his family a ray of hope. Before we go further, we want to be absolutely clear: this blog is not medical advice. We are not endorsing or discouraging the use of any medication. This is simply a retelling of a publicly available news story. Autism is a complex and varied condition, and every child’s experience is unique. What worked for one child may not work for another.
