|
|

consciousness is impaired
|
|

|
seizures with partial onset which spreads to become a generalized seizure
|
|

Describe Childhood Absence Epilepsy/Pyknolepsy (CAE)
|
Onset 5 to 12 yrs
8% of all epilepsies in school age kids Remits by puberty in 50-75% Dysfunction in thalamocortical pathways May manifest as a drop in school performance, day dreaming, staring Signs - Short stare, eye blinking or upward rolling of eyes briefly Abrupt onset & recovery of seizure, lasting 5 seconds – minute with no postictal state, Development normal Strong family history EEG: Burst of 3 Hz spike & wave on normal background |
|
Describe treatment for absence epilepsy.
|
Treatment:
Ethosuximide : is the usual choice, if typical absence Valproic acid : in typical absence with GTC and with atypical absence Lamotrigine: alone or used in combination with Valproic acid or with Ethosuximide |
|
Describe Juvenile Myoclonic Epilepsy
|
-Intelligence & examination is normal, but higher rate of psychiatric problems
Frequently observed problems are: -Inattention, behavior & poor social judgement -MRI and CT scans usually normal -family history may be positive -happens in the early morning with myoclonic jerks i.e. spills orange juice, toothbrush flies off etc -may have generalized tonic-clonic seizures -May have absence seizures |

|
Describe treatment and prognosis of Benign Rolandic Epilepsy.
|
Management:
No meds if isolated, infrequent, nocturnal seizures If seizures are often and diurnal, use antiseziure meds Carbamazepine Oxcarbazepine Prognosis: good, usually remits by 17 years of age |

|
In ages 3 months to 5 years ( most often between 6 to 18 months)
|
|
Define epileptic syndrome.
|
complex of signs and symptoms that occur together more often than by chance & that define a unique epilepsy condition.
|
|
Tonic seizure
|
seizure characterized by tonic but not clonic contractions usually occuring in Lennox-Gastaut syndrome or multiple sclerosis
Muscle "tone" is the muscle's normal tension at rest. In a "tonic" seizure, the tone is greatly increased and the body, arms, or legs make sudden stiffening movements. Consciousness is usually preserved. Tonic seizures most often occur during sleep and usually involve all or most of the brain, affecting both sides of the body. If the person is standing when the seizure starts, he or she often will fall. |
|
Atonic seizure
|
an absence seizure characterized by sudden loss of muscle tone
Muscle "tone" is the muscle's normal tension. "Atonic" (a-TON-ik) means "without tone," so in an atonic seizure, muscles suddenly lose strength. The eyelids may droop, the head may nod, and the person may drop things and often falls to the ground. These seizures are also called "drop attacks" or "drop seizures." The person usually remains conscious. |
|
Clonic seizure
|
a rare kind of seizure in which there are generalized clonic contractions without a preceding tonic phase
"Clonus" (KLOH-nus) means rapidly alternating contraction and relaxation of a muscle -- in other words, repeated jerking. The movements cannot be stopped by restraining or repositioning the arms or legs. Clonic (KLON-ik) seizures are rare, however. Much more common are tonic-clonic seizures, in which the jerking is preceded by stiffening (the "tonic" part). Sometimes tonic-clonic seizures start with jerking alone. These are called clonic-tonic-clonic seizures! |
|
Myoclonic seizure
|
one characterized by a brief episode of myoclonus with immediate recovery and often without loss of consciouness
Myoclonic (MY-o-KLON-ik) seizures are brief, shock-like jerks of a muscle or a group of muscles. "Myo" means muscle and "clonus" (KLOH-nus) means rapidly alternating contraction and relaxation—jerking or twitching—of a muscle |
|
Describe the appropriate treatment protocol for a patient who presents to the emergency room or location of care with an ongoing seizure in which the onset was not witnessed
|
Always treat a seizure that was not witnessed as status epilepticus.
