I shared material with Anna that I felt would appeal to both Winter boys with whom we were working so that the two could work alongside one another. I gave her a crossword puzzle, and Will and I worked on blending letters and completing a puzzle by numbers that correlated to colors. I thought we could then switch materials. At about 1:12 PM, without any noticeable precipitating factor or incident, Will started breathing heavily. Anna and I took note of it at the same time and commented. At first, we though he was kidding and we laughed about it as his eyes had a scary, serious look. He took about a dozen deep intakes of breath, which sounded like heavy sighs, after which his eyes became heavily hooded and he was non-reactive. He remained in that disconnected state for a approximately 12-15 minutes. At one point, tears began to roll down his eyes, but he remained non-communicative and unresponsive, despite several teachers, as well as yourself, attempting to connect with him. Will slowly came around and more responsive, around 1:20 PM. I asked his brother Jack working alongside him if he had ever seen him like that; he said he did not. I suggested to Anna to watch him in the next hour (she had him from 1:30 - 2:30), and to note the duration of the episode, if it re-occurred. I subsequently learned he was fine for the duration of the day; however as I mentioned to you, the episode reminded me of a non-epileptic seizure or a dissociative fugue state that I had seen in patients with whom I worked several years ago. I strongly recommended calling the mother and taking him to see his pediatrician or a physician. In my experience, it is unlikely that a Pre-K student would be able to remain non-responsive or shut down for that long a period of time with so many attempts to engage him. I do recall Will had a cold the other day and the incident might be a consequence of that. It is my recommendation that a doctor be advised of the incident. Thank you for listening to and acknowledging my concerns.
