Neurologic infections become emergencies when they lead to a rapid decline in a patient’s function; however, neurologic infections are often challenging to recognize.

In this episode, Aaron Berkowitz, MD, PhD, FAAN, speaks with Alexandra S. Reynolds, MD, author of the article “Neuroinfectious Emergencies,” in the Continuum® June 2024 Neurocritical Care issue.

Dr. Berkowitz is a Continuum® Audio interviewer and professor of neurology at the University of California San Francisco, Department of Neurology and a neurohospitalist, general neurologist, and a clinician educator at the San Francisco VA Medical Center and San Francisco General Hospital in San Francisco, California.

Dr. Reynolds is an associate professor in the departments of neurosurgery and neurology at Icahn School of Medicine at Mount Sinai Health System in New York, New York.

Dr Berkowitz: This is Dr Aaron Berkowitz, and today, I'm interviewing Dr Alexandra Reynolds about her article on neuroinfectious emergencies, which is part of the June 2024 Continuum issue on neurocritical care. Welcome to the podcast, Dr Reynolds. Um, would you mind, please, introducing yourself to our audience?

 

Dr Reynolds: Sure. Thank you for the invitation. I’m Alex Reynolds, and I am a neurointensivist at Mount Sinai Hospital in New York City.

 

Dr Berkowitz: Fantastic. Thanks for joining us. Dr Reynolds has written a really comprehensive article with lots of clinical pearls for the evaluation of patients with neurologic infections. So, to start off, when should we consider a neurologic infection as the cause of a patient's neurologic symptoms?

 

Dr Reynolds: That is a, really, much more complicated question than I think you recognize. I feel like a lot of it has to do with the risk factors of the patient. So, certainly, you know, a lot of times, we think about a patient who comes in with fever and altered mental status, and that's sort of the patient we're thinking about as having an intracranial infection – but, I do think there are a lot of risk factors that, sort of, may push us in that direction even if the patient doesn't have a fever or even if the patient doesn't seem like meningitis (for example). So, you know, a lot of patients nowadays are immunosuppressed, either because of infections or because of the therapies that we're using as immunosuppressants (so, autoimmune diseases, transplants, bone marrow patients). And then, I think, any patient who has had an intracranial procedure or a spinal procedure, we sort of just have to have in the back of our mind that surgical procedures come, by definition, with risk of infection (and so, that’s always something to think about). And then, certainly, anything in terms of endemic risk factors (so a patient who has come from a country that has an endemic infection), we need to just be a little bit more broad about what we're thinking about in that patient population.

 

Dr Berkowitz: That's very helpful. You mentioned something I wante
