This module provides an overview of neurological manifestations reported in association with Bartonella spp. infections.

Learning objectives:

  1. Describe the major neurological presentations that have been associated with infection with a Bartonella species.
  2. List diagnostic strategies that can be used to support a diagnosis of neurobartonellosis.
  3. Discuss potential pathophysiological mechanisms that might contribute to the neurological symptoms reported in association with Bartonella spp. infections.

The AAFP has reviewed “Neurological manifestations of Bartonella species infections” and deemed it acceptable for AAFP credit. Term of approval is from 12/15/2021 to 12/14/2022. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

This session is approved for 1.0 online enduring material activity AAFP Prescribed credits.

AAFP Prescribed credit is accepted by the American Medical Association as equivalent to AMA PRA Category 1 credit(s)™ toward the AMA Physician’s Recognition Award. When applying for the AMA PRA, Prescribed credit earned must be reported as Prescribed, not as Category 1.
