1/21/2024 0 Comments Postural reactivity definition![]() Does this patient have neurological disease?.That being said, there are a few neuroanatomical pathways that are important to know (e.g., visual pathway, sympathetic pathway leading to Horner Syndrome, cutaneus trunci reflex).Īfter performing a complete neurological exam, as well as a general physical exam and orthopedic exam (especially if any lameness or weakness), there are two questions that you should ask yourself: Clinical neurology requires only an understanding of functional neuroanatomy and lesion localization is, to a large extent, a matter of pattern recognition. While it is important to have an understanding of neuroanatomy from a global veterinary perspective, being a good clinician does not require an in-depth knowledge of neuroanatomy. I – infectious inflammatory idiopathic. ![]() With an anatomic diagnosis, one can determine a reasonable list of differential diagnoses, with significance granted using the previously reviewed evaluation of signalment and history. Cerebrum and diencephalon (thalamus, hypothalamus, etc.).Although there will inevitably be some overlap, ideally the multi-faced aspect of the exam will help indicate the location of the lesion. The intent of the neurologic exam is to “interrogate” or evaluate different aspects of the nervous system that are specific to a particular area. When trying to gain a neuroanatomical diagnosis, it is always best to start broadly, then narrow the focus. Once one feels confident in knowing what is “normal”, comfort in identifying the “abnormal” and localizing the lesion will come more naturally. The key to performing an accurate neurologic examination is perfecting one’s examination skills, first on a normal patient. Muscle tone, size, and segmental reflexes.Postural reactions – conscious proprioception, hopping, wheel barrowing, tactile and visual placing.Gait and posture – ambulation, ataxia, paresis/plegia, lameness.Sensorium – mentation general observations and interaction with the environment.The neurologic examination can then be focused upon, again with attention to consistency and documentation. This should begin with reviewing the complete history and performing a full physical examination. Aspects of the neurologic examinationĪs with any examination, being consistent is immensely important. The aim of this post is to review functional neuroanatomy and neurolocalization as it pertains to lesions within the central and peripheral nervous systems. Performing a good neurologic examination with proper neurolocalization is critical for devising a suitable list of differential diagnoses with subsequent treatment plans with patients presenting with neurological diseases.
