Abstract
This paper is the first in a series of four case-controlled reviews of neurological disorders in pediatric medicine. It examines the pathophysiology, diagnostic markers, and clinical features of Chronic Inflammatory Response Syndrome (CIRS) through molecular immunology, functional transcriptomics, neuroimaging, and biomarker integration, with a focus on children with special needs. Clinical observations by the lead author highlight recurring similarities that warrant closer investigation of the neuroimmune inflammatory mechanisms underlying overlapping symptoms in autism spectrum disorder (ASD). Identifying and treating CIRS may be a critical step toward improved prognosis, with sustained gains and symptom alleviation in treatment-resistant populations. This review underscores the concept that ASD, and CIRS represent subsets within a shared paradigm of neuroinflammatory and immune-mediated disorders affecting human health worldwide. These conditions may be considered indistinguishable across populations due to overlapping neurological, immunological, and biochemical features.
