Status Epilepticus Flashcards
What is status epilepticus
Rapidly repeating seizures without recovery between episodes or prolonged epileptic activity
How long does status epilepticus last
30 min or more
5-10 min impending in children
What is the incidence rate of status epilepticus
17-108/100,000
1-8% of hospital admission for epilepsy are for SE
4-16% with epilepsy have at least one episode of SE
1/3 first seizure
1/3 no history
1/3 established epilepsy
What is the underlying mechanism of status epilepticus
Loss of inhibition
What happens in crowding effect
Healthy tissue takes over damaged tissue in an attempt to recover function - forgoes specialization for proper development
What brain structure is most vulnerable with status epilepticus
Hippocampus - can cause sclerosis
Who is most effected by status epilepticus
Younger children prior to 11 months presenting with febrile status epilepticus
What functions are most vulnerable after status epilepticus
Hand-eye coordination, motor ability, and memory - executive function depends on critical period of development
What is the prognosis for status epilepticus
Idiopathic status epilepticus tends to have more favorable prognosis than symptomatic status epilepticus
Risk of developing seizures after status epilepticus
50% in convulsive symptomatic status epilepticus
20% with acute symptomatic status epilepticus
Developmental and cognitive impairment - compared to 10% in other types of status epilepticus
Suggested hypothesis for resilience in status epilpticus
Brain can develop tolerance to recurrent seizure more than naive brain
Cognitive findings in status epilepticus
Younger children - more severe etiologías - 75% under 2 with status epilepticus had normal development before SE. Increased risk for neuronal injury or death > or equal to an hour
Findings for gender with SE
Males have a higher propensity of developing idiopathic SE but gender itself does not impact prognosis
What does it mean for seizures to be refractory
Seizures persist despite adequate treatment
Prognosis of status epilepticus depends on
Etiology, age, and duration
