- Simple: Level of consciousness is unchanged during seizure
- Complex: less alert, impaired consciousness
- Starts at one spot in brain
- Can become generalized
Describe a generalized seizure.
- Entire brain affected
- Absence
- Myoclonic
- Atonic: slump to ground
- Clonic: rhythmic movements
- Tonic: stiffening
- Tonic-clonic: fall to ground then shake
Describe a febrile seizure.
- Usually benign and happens just once
- If complex more likely to recur or develop into epilepsy
What is Childhood Absence Epilepsy (CAE)?
- 3 hz spike wave on EEG
- Impaired consciousness w/o loss of muscle tone
- Often resolves in adolescence
What is Juvenile Myoclonic Epilepsy?

- Does not resolve with age
What are generalized tonic-clonic seizures?
- Aka grand mal

- If early higher risk of ICH
- If late, higher chance of post-traumatic epilepsy
People who have had 0 or 1 seizures are at a high risk for recurrence if:

- Neurological exam abnormalities present
- 1st seizure occurred out of sleep
- Abnormal EEG
What are some causes of Breakthrough seizures?
- Missed doses of meds
- Alcohol
- Sleep loss
- Ilness
What are some teratogenic effects of seizure meds?
- Cardiac septal defects
- Nerve tube defects
- Cleft lip/palate
- Urogenital defects
- MIDLINE DEFECTS
What is eclampsia and its tx?
- HTN, proteinuria, seziure
