seizures Flashcards
what type of epilepsy are absence seizures?
generalised
what is the typical age range for absence seizures?
3-10 years old and more common in girls than in boys
which things may provoke an absence seizure?
eizures may be provoked by hyperventilation or stress
what is the management and prognosis of an absence seizure?
sodium valproate and ethosuximide are first-line treatment
good prognosis - 90-95% become seizure free in adolescence
what are the branches of the trigeminal nerve?
v1- ophthalmic branch = Ophthalmic nerve lesions may result in a sensory deficit of the globe, lacrimal glands, side of the nose, upper eyelids, and frontal sinuses. There may also be a loss of the corneal reflex
v3- mandibular branch
how can you remember the side effects of sodium valporate?
V - VALPROATE: A - Appetite increase --> weight gain L - Liver failure P - Pancreatitis R - Reversible hair loss (alopecia) O - Oedema A - Ataxia T - Teratogenic, tremor, thrombocytopaenia E - Enzyme inducer (p450), encephalopathy (due to high ammonia)
what is Todds paresis?
A focal weakness, typically of the frontal lobe (motor strip), may occur following a focal-onset seizure - this is called Todd’s paresis. During a focal seizure, patients can either be aware or unaware of their surroundings.
what are the symptoms of a temporal lobe focal seizure?
Hallucinations (auditory/gustatory/olfactory), Epigastric rising/Emotional, Automatisms (lip smacking/grabbing/plucking), Deja vu/Dysphasia post-ictal)
what are features of frontal lobe seizures?
Head/leg movements, posturing, post-ictal weakness (Todd’s paresis) , Jacksonian march
what are features of a parietal lobe seizure?
Paraesthesia
what are features of an occipital lobe seizure?
Floaters/flashes
which drug makes absence seizures worse?
carbamazepine
how can you differentiate between a generalised tonic clonic seizure and a vagal syncope episode?
tonic clonic seizures have longer post octal phases
in which type of seizure do patients grab their clothes?
temporal lobe
what type of epilepsy does Jacksonian movements suggest?
frontal
