Central Nervous System Case Study1. Why does the physician suspect either meningitis or encephalitis? 2. If the diagnosis is in doubt, why are antibiotics administered immediately? 3. How do the results obtained from the spinal tap and blood sample support the diagnosis? How do the results obtained from the spinal tap rule out viral encephalitis? 4. Other than meningitis or encephalitis, what conditions could account for some or all of Heather’s signs and symptoms? 5. Why are fluid and electrolyte replacement necessary? 6. If inflammation of Heather’s meninges had caused compression of the brain, how would the ventricles appear in the CT scan? 8. Recall that virtually all cases of polio in the United States now result from the polio vaccine itself. In light of this, would you choose to have your child vaccinated against polio? Why or why not? 9. Which type of glial cell do you think is responsible for the scars that form in amyotrophic lateral sclerosis? Explain. 10. Al is brought into the emergency room after a motorcycle accident. At the scene, he was found unconscious, with numerous scrapes and bruises on the left side of his head and swelling above his right ear. When he regains consciousness 3 hours later, he complains of a headache and appears dazed. His speech is slurred, and his pupils are equal and reactive to light. Twenty-four hours later, all signs appear normal. Which of the following is the most likely diagnosis of Al’s condition?a. mild concussionb. massive subdural hematomac. severe concussiond. meningitise. cerebral contusion Chronic traumatic encephalopathy (CTE) has been found in a high percentage of professional athletes from repetitive head injuries.
