CHAPTER 1
Signalment and History: The First Considerations

Curtis W. Dewey & Ronaldo C. da Costa

Introduction

When presented with a patient that is suspected of having a neurologic disorder, the signalment (i.e. breed, age, and sex) and history are often helpful in guiding the clinician toward the most likely diagnosis. It is important to recognize, however, that this information is adjunctive to the neurologic examination. Properly weighting the importance of signalment and history will help avoid “tunnel vision” when devising diagnostic plans and implementing treatment strategies.

Signalment^{1–3, 5}

The information in Table 1.1 and Table 1.2 provides a summary of suspected and confirmed breed predilections for various neurologic disorders. Knowledge of breed predilections can be very helpful when considering differential diagnoses, especially for uncommon presentations (e.g. neuropathies in juvenile patients). The clinician should be aware of the limitations of breed predilection tables, however. Newly discovered breed predilections or undiscovered breed predilections will not necessarily be represented in a table. In other words, breed predilection tables tend to increase in size with successive textbook editions. Also, breeds other than those reportedly predisposed to a particular disorder may occasionally be affected by that disorder. Finally, certain rare disorders may have only one or a few members of a certain breed reported in the literature. Since some of these disorders are inherited (e.g. lysosomal storage diseases), it may be assumed that the breed is at risk, despite low numbers of actually confirmed cases.
