The prognostic value of the Modified Glasgow Coma Scale in head trauma in dogs. Defining mental status can be difficult and nuanced; however, characterizing a patients level of consciousness as well as quality of consciousness can give the clearest picture of the patients mental state.4 Consciousness is produced by the appropriate function of both the forebrain and the ascending reticular activating system in the brainstem.4 Dysfunction of either of these areas, or both, results in the clinical observation of abnormal mental state.4. Body temperatureHypothermiaHyperthermia The most obvious etiology is head trauma. AAHC. Repeat neurologic examinations are helpful to detect subtle changes or progression of signs. A nonslippery surface and good support of the animal are essential to detect subtle deficits. For veterinary nurses, using the neurologic examination as an assessment tool provides objective information about a patients status.1 This information can set a baseline of patient status to which positive or negative changes in neurologic status can be compared.1 Understanding neurologic examination findings can also aid in anticipating potential complications when developing a care plan for an individual patient. Within each category a score of 1-6 is assigned. Patients will often present with focal facial seizures that may progress to a more generalized seizure.

The neurologic examination reveals the following: The presence of multiple abnormalities on the cranial nerve evaluation, delayed proprioception in all limbs, and reduced mental status localize neurologic concerns to the brainstem. 7. The patient should not be walked backwards (ie, reverse wheel barrowing). It is therefore essential to monitor the neurological status of all ICU patients, giving particular attention to clinical signs of brain swelling, spinal cord compression, and systemic influences that may affect nervous tissue function. } IIOptic Mesencephalon(midbrain) The most commonly performed is proprioceptive placing, often referred to as conscious proprioception or CP testing.
