1. What is a seizure?
    Discharge of excessive electrical energy from nerve cells located within the brain.
  2. Primary Seizure?
    Caused by abnormal cells and no underlying cause can be identified.
  3. Secondary seizures?
    Outside factors- head injury, drug overdose, environmental exposure cause secondary seizures.
  4. Classification of seizuures?
    Generalized seizure and Partial seizure.
  5. Generalized seizure?
    • Begins in one area than spreads throughout the brains. Pts usually experiences LOC b/c of the massive electrical activity.
    • -Tonic-clonic seizures     -Absence seizures
    • -Myoclonic seizures       -Atonic seizures
    • -Clonic seizures             -Tonic seizures
    • -Status epilepticus.
  6. Partial seizure?
    Also called focal seizures because they involve one area of the brain & do not spread throughout. Classified as simple partial seizures and complex partial seizures.
  7. Tonic-clonic seizures?
    Also known as grand mal, involuntary muscle contraction followed by relaxation appearing as aggressive spasm, LOC and confusion and exhaustion.
  8. Absence seizures?
    Short LOC (3-5 secs), commonly in children around 3 years of age & disappears by puberty, do not involve muscle contraction.
  9. Myoclonic seizures?
    Short muscle contractions, relatively rare and are often secondary seizures; sudden excessive jerking of arms, legs and entire body. 
  10. Atonic seizure?
    Sudden loss of muscle tone, arms & legs collapse, recovery is rapid.
  11. Clonic seizures?
    Rhythmic bylateral chronic jerking.
  12. Tonic seizures?
    Stiffening of muscles.
  13. Status epilepticus?
    Potentially the most dangerous of the seizures; seizure rapidly recurrs again and again w/ no recovery in between.
  14. Simple partial seizures?
    Occur in a single area of the brain and may involve a single muscle movement or sensory alteration. 
  15. Complex partial seizures?
    Involves a series of reactions or emotional changes and complex sensory changes such as hallucinations, mental distortion, changes in personality, loss of consiousness, and loss of social inhibitions. Motor changes include involuntary urination, chewing motions, diarrhea and so on. Onset occurs by late teens.
