1 of 20
A tendency to have recurrent seizures (more than one unprovoked seizure)
Epilepsy
2 of 20
Abnormal neuronal discharge which suddenly happens in the whole brain at once - in both cerebral hemispheres
Primary generalisation
3 of 20
Abnormal neuronal discharge which occurs in a certain region of the brain
Partial seizure
4 of 20
Abnormal neuronal discharge which originates in a certain region before spreading through the whole brain
Partial seizure with secondary generalisation
5 of 20
A partial/focal seizure which occurs without a loss of consciousness
Simple
6 of 20
A partial/focal seizure which impairs consciousness
Complex
7 of 20
The lobe where most complex partial seizures occur
Temporal
8 of 20
A type of generalised seizure where patients may fall, become rigid with jaw clenching, have rhythmic jerking of the limbs, urinary incontinence.
Tonic clonic
9 of 20
A type of generalised seizure where there is a sudden momentary loss of contact with the surroundings, usually occurs in children, may occur several times a day without the child's awareness, and it could present as learning difficulties
Typical absence
10 of 20
A type of generalised seizure which tends to occur in children with brain damage, it tends to be prolonged and it is associated with dropping to the ground leading to injuries
Atypical absence
11 of 20
A type of generalised seizure with sudden, brief jerks that affect the upper limb and are with or without loss of consciousness. They occur late in childhood and often in the mornings
Myoclonic
12 of 20
An investigation done in suspected epilepsy which looks at electrical activity/neuronal discharge within the brain BUT a normal result does not exclude the diagnosis of epilepsy
EEG
13 of 20
The most common type of neuroimaging done in suspected epilepsy which looks at the structure of the brain to identify any lesions or tumours that could have contributed to the seizure
MRI
14 of 20
A dangerous condition in which tonic-clonic seizures follow one another without recovery of consciousness between them (usually more than 5 mins duration)
Status epilepticus
15 of 20
The most severe teratogenic AED
Sodium valproate
16 of 20
AED that is used in status epilepticus but does not cause sedation
Phenytoin
17 of 20
A common side effect in classic AEDs such as phenobarbital which is not seen in newer drugs
Sedation
18 of 20
AED that can be used in pregnancy
