The doctor will take a health history and may ask about:

  • Past health history
  • Family health history
  • Medicines currently or recently taken
  • The seizure:
    • What a person was feeling or doing before it happened
    • The age when it started
    • If there was any warning before it
    • What the seizure looked like to others
    • If there were any symptoms after the seizure, such as being unable to move, tongue biting, or loss of bladder function
    • How long the seizure lasted
    • How many seizures a person has had

A physical exam may be done. Special focus will be given to the nervous system. Tests will be done to see if a person has epilepsy and the type of seizures they have.

  • Brain activity may need to be tested. This can be done with:

  • Blood tests may be done to check for causes of the seizures, such as:
    • Metabolic problems with levels of sugar, calcium, sodium, potassium, or magnesium
    • Problems with the immune system that can be related to hidden cancer (called paraneoplastic syndromes)
    • Genetic problems
    • Infections, such as encephalitis, meningitis, or HIV
    • Lead poisoning
  • Urine tests may be done.
  • A lumbar puncture may be done to check brain and spinal cord fluid.
