Note should be taken of the patients mental status, any unusual movements or postures, difficulty navigating the environment, and gait. As a few examples, a patient may stand at the wrong side of a door to enter or exit, gentle petting may invoke a painful response (hyperesthesia), or the patient may vacillate unpredictably from aggressive to compliant. The functions of the cranial nerves (Table 12.6) are assessed to evaluate the health of the peripheral nerve and the area of the brainstem containing the nucleus of that nerve. Aspiration pneumonia can be a devastating complication. Cervical and tail range of motion may also be performed for additional information. Normal cranial nerve function reduces the likelihood of a lesion in a specific region of the brainstem. Deficit results in medial strabismus The neurological examination usually begins with an assessment of seizures, mentation, level of consciousness, cranial nerves, and basic body posture to identify and localize intracranial problems.

Confirm the existence of a neurologic condition. A patient with abnormal mentation may be described by a progression of adjectives that range from least to most affected: depressed, obtunded, stuporous, and comatose. Asymmetrical neurological deficits suggest a more focal disorder, such as mass, infarct or hemorrhage. 3rd ed. Menu. Along with the Small Animal Coma Scale (SACS), the Modified Glasgow Coma Scale (MGCS) was proposed as a means of objectively evaluating the neurological status of dogs after traumatic brain injury.
