Research Summary

Dr. Jones-Brando’s research revolves around the Stanley Neurovirology Laboratory’s working theory that an infectious agent plays a crucial role in the etiology of serious psychiatric disorders such as schizophrenia and bipolar disorder.

She uses classical microbiological, molecular biological and histochemical techniques to examine samples – including brain cells, cerebrospinal fluid, blood components, and throat cultures – to search for parasites, viral particles and macromolecules.

Dr. Jones-Brando also uses virus-host and parasite-host cell systems to study the effects of a variety of compounds – including antipsychotic and mood-stabilizing drugs, plant extracts, nutraceuticals and novel synthetic compound panels – on the in vitro replication and in vivo growth of infectious agents.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
