Immune-to-brain communication. Three independent pathways establish the immune-to-brain communication: neural (1), humoral (2) and cellular (3) routes.

The Neuropsychiatry Program (NPP) is involved in the systematic investigation of psychiatric disorders and/or behavioral syndromes in neurological diseases, specifically neurodegenerative conditions such as Alzheimer’s Disease, Parkinson’s Disease, Huntington’s Disease and ALS. Using advanced neuroimaging tools, the program aims to advance the understanding of neurobiological underpinnings of pathological behavior. The NPP is also interested in the role of immune mechanisms in cognition and emotion. In a project supported by the Huntington’s Disease Society of America, researchers are evaluating whether inflammation in the blood is associated with inflammation in the central nervous system (CNS) in patients with Huntington’s Disease and whether this is associated with psychiatric disorders.

Led by Antonio L. Teixeira, M.D., Ph.D., M.Sc., the NPP is currently studying:

  • Microglial activation in Huntington’s Disease: A Structural and Functional Study.
  • Biomarkers across neurodegenerative diseases – Alzheimer’s disease, Parkinson’s Disease, Huntington’s Disease, Progressive Supranuclear Palsy, Amyotrophic Lateral Sclerosis(ALS).
  • The neuropsychiatric syndromes in Huntington’s Disease and Parkinson’s Diseases.

The Neuropsychiatry Program works with researchers around the world, including in Brazil, the U.K and the Department of Neurology at the McGovern Medical School. Those who are interested in this research are invited to contact Dr. Teixeira for research opportunities and collaborations.
