About Neuroinflammatory Disorders
Immune mediated neuroinflammation is a growing area of interest linking immune system activation with changes in brain function and behavior. Understanding these connections is essential for diagnosing and managing complex medical conditions.
Impacted Disorders and Illnesses
A wide range of conditions involve known or suspected immune-mediated neuroinflammation that results in neuropsychiatric symptoms. Understanding the clinical features, immune mechanisms, and psychiatric impact can transform how we approach care and research.

Neurodegenerative Disorder Alzheimer's Disease
A progressive neurodegenerative disorder that affects memory, cognition, behavior, and daily functioning.
Alzheimer’s disease research suggests it may reflect an infection-inflammation model in which immune dysregulation, pathogen exposure, and neuroinflammation contribute to cognitive decline, often accompanied by neuropsychiatric symptoms.

Inflammatory Bowel Disease Crohn's Disease
A chronic inflammatory bowel disease that can affect the digestive tract and contribute to systemic immune dysregulation.
Crohn’s disease is driven by complex interactions between pathogens, immunity, and neuroinflammation. Dysregulated gut–brain signaling may underlie both intestinal flares and systemic neuropsychiatric manifestations.

Autonomic Disorder POTS and Dysautonomia
Disorders of the autonomic nervous system that can affect heart rate, blood pressure, energy regulation, and cognitive function.
POTS and Dysautonomia can follow viral or bacterial infections. Immune activation, autoantibodies, and neuroinflammation may impair autonomic regulation, resulting in diverse cardiovascular and neuropsychiatric manifestations.

Post-Infectious Condition Long COVID
A post-infectious inflammatory condition that can occur after a SARS-CoV-2 infection.
Long COVID is a post-viral syndrome where persistent immune dysregulation and neuroinflammation drive fatigue, cognitive dysfunction, and neuropsychiatric symptoms.
Research Roadmap
Research is revealing a powerful connection between the immune system and brain function. Scientists are uncovering how immune responses can influence neurological health across a range of conditions — from neurodegenerative diseases to psychiatric disorders.
By unraveling the complex overlaps, researchers are laying the groundwork for more targeted, effective treatment strategies.
Discover how immune system responses can drive brain inflammation and contribute to complex neurological and psychiatric symptoms.
