Neurologic Infectious Disease

The NID Section Head is David Clifford, M.D.

The NID Section consists of Dr. David B Clifford and Dr. Beau Ances.  The section was formed to specifically address the neurological complications encountered in HIV patients, but members of the section treat a wide variety of serious brain inflammatory conditions. Members of the section are involved with and collaborate in the Center for Neuroinfectious and Neuroimmunologic Diseases (CNND).

Specific areas of interest include;

  •    NeuroAIDS conditions
    • HIV Associated Neurocognitive Disorder
    • HIV associated neuropathy
    • Progressive multifocal leukoencephalopathy
    • Cryptococcal meningitis
    • Cytomegalovirus encephalits
    • Toxoplasma encephalitis
    • Neurosyphilis
  • Autoimmune encephalitis
  • Neurosarcoidosis
  • Creutzfeld Jakob  and other brain prion diseases


Training in diagnosis and treatment of neurologic infectious and inflammatory conditions is provided for medical students, residents, and fellows.  A flexible fellowship for post residency training in this area is available.  Dr Clifford leads a teaching and learning rotation at Ayder Hospital and Mekelle University in northern Ethiopia providing residents and students the opportunity to contribute to neurologic education in Ethiopia while learning about the challenges of global medicine and neurology.


Members of the section are national leaders in issues surrounding neuroinfectious and neuroinflammatory disease, and hold multiple NIH grants supporting ongoing research to enhance the understanding of these disorders.  Dr. Clifford is the Co-Principal Investigator for the Vanderbilt AIDS Clinical Trials Group Unit and PI of the Washington University Clinical Research Site.  He is also PI for the CNS AntiRetroviral Therapies Effects Research (CHARTER) site at Washington University. Dr. Ances is an international leader in advanced imaging techniques addressing brain involvement and has grants focusing on impact of HIV infection in adolescents and in aging adults.  The research activities are carried out in the newly constructed building at 620 S Taylor Avenue that co-houses the Washington University Infectious Diseases Clinic.
