Although usually treated with antibiotics and minimal long-term effects, there have been 3 reported case of tachycardia more than one year after exposure. Pathologists believe that the increased incidence of CSD is due to cat owners neglecting to vaccinate their cats. History
Symptoms similar to CSD were first described by Henri Parinaud in 1889, and the clinical syndrome was first described in 1950 by Robert Debré. In 1983, the Warthin-Starry silver stain was used to discover a Gram-negative bacillus which was named Afipia felis in 1991 after it was successfully cultured and isolated. The causative organism of CSD was originally believed to be Afipia felis, but this was disproved by immunological studies in the 1990s demonstrating that people with cat-scratch fever developed antibodies to two other organisms, B. henselae (originally known as Rochalimea henselae before the genera Bartonella and Rochalimea were combined) and B. clarridgeiae, which is a rod-shaped Gram-negative bacterium.

Among the earliest developed neurorehabilitation practices is Frenkel exercises, which was developed by Heinrich Frenkel in the mid nineteenth century; these exercises were drawn from contemporary physical medicine and rehabilitation techniques, called medical gymnastics, and from everyday activities, like standing up from a chair, to find exercises which are closely related to the pathology of ataxia and rely on slow practice and on the individuals perseverance to relearn key motor skills, replacing lost proprioception with visual feedback. There are exercises for lower limbs, like extending the legs, and upper limbs, like placing pegs in boards, and depending on the severity of the ataxia can be performed laying down, sitting, or standing up. All exercises often start with simple movements and become progressively more difficult to emulate real world movements affected by the disorder.Common recommendations for persons with dysphagia, or swallowing problems, include pureeing food, replacing difficult to eat foods in the diet, or changing posture during eating. When swallowing problems become severe enough that aspiration pneumonias are frequent or dietary changes fail to prevent weight loss, a feeding tube may be considered. : 82–86  Typically these are percutaneous endoscopic gastrostomy jejunal tubes (PEG-Js), however these do not necessarily lead to a decreased incidence of aspiration, as clogs may result in gastroesphageal reflux which can be aspirated. Direct PEG-Js seem to cause less frequent reflux and have lower incidence of aspiration pneumonia compared to the standard PEG-J procedure.
