PhosphorusIncreasedDecreased Veterinary professionals lack the luxury of patients describing their medical problem and, therefore, must rely on studious examination to reach a conclusion.1 In patients presenting with neurologic signs, systematic examination of the nervous system can identify an area of concern, a process called neuroanatomic localization.2 The neurologic examination, joined with patient history and physical examination, is therefore an invaluable diagnostic and monitoring tool in veterinary medicine. Modified Glasgow Coma Scale (MGCS), mentation, and animal trauma triage (ATT) scores were also calculated. Basic physical parameters to monitor begin with temperature, pulse, and respiration, which reflect central nervous system (CNS) energy demands, CNS perfusion capabilities, and brain control of ventilation.
