Dull mentationDull mentation Strychnine Euglycemia <180mg/dL The choice of tests and the sequence in which they are performed will vary depending on patient status. Function Stupor or coma can occur with lesions anywhere in the cerebrum or brainstem, due to dysfunction of the ascending reticular activating system (ARS). Some veterinarians prefer the 1-9 scale, which has more latitude to identify subtle changes in weight. Common causes of alterations in mentation and consciousness include brain trauma, neoplasia, and inflammation as well as systemic metabolic or inflammatory disease, intoxication or prescribed medications (see Table 12.2). The neurologic examination can be divided into 5 parts: mentation, posture, and gait observation; postural reactions; cranial nerve evaluation; spinal reflex evaluation; and spinal palpation. Proprioceptive receptors are present in muscles, Several techniques can be used to assess proprioception in a veterinary patient. As the patient recovers and pelvic limb withdrawal reflexes return, the care plan should be updated to reflect the decreasing risk of decubital ulcers, urinary incontinence, and skin damage.
