Paeds epilepsy Flashcards
What is an epileptic seizure?
Transient occurrence of signs &/or symptoms due to abnormal/excessive or synchronous neuronal activity in the brain
Unprovoked
What is epilespy?
A disorder of brain characterized by enduring predisposition to generate epileptic seizures & the neurobiologic, cognitive, psychological, and social consequences of this condition
What are epileptiform discharges?
spikes, polyspikes, sharp waves, or spike and slow-wave complexes without observed clinical seizures
Observed in 2-5% of children without epilepsy
How is an epilepsy history taken?
Do they have video?
Beginning, middle, end description

Behaviour/emotional impact

What are the 5 axes for classification of seizures?
1 Description of seizures (ictal semiology)
2 Seizure type (myoclonic absence)
3 Syndrome diagnosis
4 Aetiology (TS/Stroke etc)
5 Degree of impairment
What is a focal seizure?
Isolated to 1 hemisphere
What are the different types of generalised seizure?
- Tonic-clonic seizure: bilateral increased tone and then bilateral sustained rhythmic jerking
- Tonic seizure: Increased tone, most commonly happen while sleeping
- Atonic seizure: sudden loss of muscle strength
- Myoclonic seizure: shock-like jerks of muscles
- Epileptic spasms: type of seizure seen in infancy
What are generalised seizures?
Ones that rapidly engage bilaterally distributed networks
What are febrile seizures?
6m-5yrs
Immunisations – fever not the jab
1in 50 will have one
50% if fam hx/neurodeve/complex
?recurrent give buccal midaz within 2mins
What are infantile spasms?
A type of seizure that occurs in babies
The spasms look like a sudden stiffening of muscles, and the baby’s arms, legs, or head may bend forward
The seizures occur in a series of short spasms, about one to two seconds in length
What is Childhood absence epilepsy?
12% of childhood epilepsy
5 - 7 yrs
Frequent, typical absence seizures 100s/day lasting about 10s
90% disappear by childhood
What is a juvenile absence seizure?
10-12 yrs
Overlaps with juvenile myoclonic epilepsy
Absence seizures cluster upon awakening
photosensitivity in 20%
Long-term prognosis is unclear
What can precipitate a generalised tonic-clonic seizure?
Sleep deprivation (80%)
What is Benign Rolandic Epilepsy?
Most common childhood epilepsy (8 -23%)
3-13yrs age at onset, peak 9yrs
Daytime and night time seizures
Lateralised facial contraction/anarthria, dribbling/ grunting sound, no LOC +/- same upper limb – secondary generalisation can supervene
What are childhood epilepsy with centrotemporal spikes?
AKA CECT’s
Can occur day or night
