Symptom narrative

Following this set of vaccinations, child became extremely ill within 3 weeks. He developed a high fever and respiratory distress, which lasted over 2 weeks - far more severe than any prior illness. After recovering from the physical symptoms, he did not return to his prior developmental state. He had previously been meeting and exceeding milestones, but after this illness, we observed the following regressions: lost all previously acquired speech, stopped making eye contact, no longer responded to his name, began repetitive hand-flapping, begin banging head on objects, developed sleep disturbances, appeared disconnected, as if trapped in his own body. Symptoms have persisted long-term. He was formally diagnosed on August 7, 2023, with: level 2 nonverbal autism (F84.0) As well as mixed receptive-expressive language disorder (F82.0), lack of expected normal physiological development in childhood (R62.50), abnormality of gait and mobility (R26.89). He currently presents with significant impairments in language, gross motor, fine motor, sensory processing, and social responsiveness. Currently receiving support therapies.
