What’s a tonic seizure
These seizures manifest with a spasm of the body with stiffened limbs and may even result in backward arching of the back followed by loss of consciousness (STIFFENING)
What’s a myoclonic seizure
These manifest as brief jerky movements of the muscles with preserved consciousness
What’s a clonic seizure
These are repeated jerky contractions which could have a focal or generalized presentation, depending on how much of the brain surface is involved (JERK)
What’s a tonic-clonic seizure?
This is the commonest form of the seizures with a tonic (stiffening) phase followed by a clonic (jerk) phase
What’s the commonest form of seizure
Tonic-clonic
What are Atonic seizures
These seizures are characterized by a loss of tone of the body with the patient falling to the ground.
What’s a hyperkinetic seizure
These are characterized by an agitated movement of a body part like pedaling of the feet
Focal seizures that are of impaired awareness, are characterized by what?
Clouding of consciousness, patient can’t remember attack (Amnesia) and automatism.
Explain absence seizures
Brief attacks where the patient loses consciousness, they abruptly stop and resume, and have no memory of the attack. Genetic and predominantly in children.
What is the most common cause of non epileptic seizures in children
Febrile convulsions
Antiepileptic drug for Generalized seizures?
Valproate
Antiepileptic drug for Abscence seizures?
Ethosuximide
Antiepileptic drug for Focal seizures?
Carbamazepine and phenytoin
Valproate and carbamazepine are contraindicated in who and why?
Pregnant women, associated with congenital defects
What is Status Epilepticus?
Defined as repeated seizures without regaining consciousness for more than 30 mins OR a single one longer than 5 mins.
Status epilepticus causes?
It may result from sudden withdrawal of antiepileptic drugs, non-compliance to treatment or any other cause of seizures
First line therapy for Status Epilepticus?
IV Benzos
A patient presents with “lightning-like” jerks of the arms upon waking, sometimes leading to a generalized tonic-clonic seizure. Which of the following antiepileptic drugs should be AVOIDED as it may exacerbate this seizure type?
A) Valproate
B) Levetiracetam
C) Phenytoin
D) Clonazepam
Phenytoin
Any patient with seizures and a fever requires which investigation?
A lumbar puncture
A 7-year-old child has brief episodes of staring and eyelid fluttering lasting 10-15 seconds, during which he is unresponsive. He resumes his previous activity immediately afterward with no memory of the event. The interictal EEG is likely to show which of the following patterns?
a) Focal spike-and-wave discharges in the temporal lobe
b) 3 Hz spike-and-wave discharges
c) Polyspike discharges
d) Hypsarrhythmia
3Hz spike-and-wave discharges
. A 25-year-old patient presents with a seizure that began with twitching of his right thumb, which then spread to involve his entire right hand and arm over 30 seconds before he lost consciousness. This progression is most characteristic of:
a) Atonic seizure
b) Jacksonian march seizure
c) Absence seizure
d) Psychogenic non-epileptic seizure
Jacksonian March seizure
A patient presents with recurrent episodes characterized by impaired awareness, stereotyped lip-smacking movements, and amnesia for the event. These seizures most commonly originate from which lobe of the brain?
a) Frontal
b) Temporal
c) Parietal
d) Occipital
Temporal
Which of the following antiepileptic drugs should be avoided in a patient with myoclonic seizures due to its potential to exacerbate this seizure type?
a) Valproate
b) Levetiracetam
c) Phenytoin
d) Clonazepam
Phenytoin and carbamazepine
A 45-year-old man is brought to the emergency department with continuous generalized tonic-clonic seizures for 15 minutes. After securing ABCs (airway, breathing, circulation), what is the most appropriate first-line pharmacological treatment?
a) Intravenous phenytoin
b) Intravenous valproate
c) Intravenous benzodiazepine
d) Intravenous phenobarbita
