  1. Cardiac dysrhythmia
    • Rationale:
  2. Congenital malformation in the brain.
    • Rationale:
  3. Head trauma.
    • Rationale:
  4. Drug over-dose.
    • Rationale:



One of the most common reasons for tonic-clonic seizures in adults is traumatic brain injury that may occur from accidents and other traumas. Cardiac dysrhythmias are not a frequent cause of seizures in adults. Congenital malformations usually develop prior to or are present at birth. Seizures experienced due to congenital malformation usually occur while young and not suddenly following head injury as an adult. Usually seizures may occur with drug withdrawal and are not common among regular adult populations.
