Diagnosis Checklist: Questions your doctor may ask (and why!)

During a consultation, your doctor will use various techniques in their assessment of Encephalitis. Your doctor may ask several questions when assessing your condition. It is important to remember that your consultation is a two-way process and any extra information you can share with your doctor about your symptoms may help them with their diagnosis. Some of the questions your doctor may ask are listed below:

• What symptoms of encephalitis do you have? - encephalitis can present in many ways, depending partly on the organism responsible. Possible symptoms include fever, headache, stiff neck irritability, drowsiness, vomiting, seizures and sometimes psychiatric symptoms such as hallucinations.
• What is the age of the person? - more difficult to diagnose in children e.g. symptoms in infants include fever, pallor, vomiting, lethargy, refusing to feed, bulging fontanelle, neck stiffness.
• Have you had a recent viral infection? - e.g. post-infectious encephalitis may occur up to 14 days after infection with measles, varicella zoster (chicken pox), rubella, mumps and influenza. Other more rare causes include Rabies, polio and HIV.
• Have you had measles in the past? - Measles may also cause a sub-acute sclerosing panencephalitis (SSPE) about 6 years after the original infection with slow deterioration leading to death.
• Have you got a bacterial infection else-where? - Bacterial cause (especially Staphlococcus aureus) is usually secondary to a pus infection elsewhere e.g. abscess.
