1

Psychogenic nonepileptic seizures (PNES)

Paroxysmal (sudden) episodes that resemble epileptic seizures; however, PNES are psychological in origin.

2

How do you differentiate PNES from an epileptic seizure

Video- EEG monitoring in an epilepsy monitoring unit. PNES will not show epileptiform activity on the EEG.

Pt has a seizure in the hospital. What do you do?

- ABC (airway, breathing, circulation)
- Place the patient on their side and administer oxygen
- Ask the nurse to administer a benzodiazepine
- Consider loading with anti-epileptic meds

5

Seizures divided into what 2 groups

- Partial (focal)
- Generalized

6

Definition of a partial seizure

- Starts in one hemisphere
- Can secondarily generealize

7

Definition of a generalized seizure

- Those in which the first clinical changes indicate initial involvement of both hemispheres

8

Patial seizures may be divided into 2 categories

Simple Partial- consciousness intact
Complex partial- consciousness not intact

9

Types of generalized seizures

A- Absence
M- Myoclonic
C- Clonic
T- Tonic-clonic
T- Tonic
A- Atonic

10

Absence seizures:

Brief loss of consciousness where they stop doing whatever it is they were doing and stare at you blankly.
- lasts up to 30 seconds

11

ABsence seizures may be induced with?

HYPERVENTILATION...know

12

Absence characterized by what type of EEG behavior

3 hz spike and wave discharges

13

Febrile seizures

most common type of childhood seizure, affect 2-5% of children in the USA.

14

Peak incidence of febrile seizures

18 months

15

Definition of febrile seizures

Seizures that occur in kids with fevers between the ages of 6 and 60 months who do not have an intracranial infection, metabolic disturbance, or history of afebrile seizures

16

Simple febrile seizure

Isolated (once in a 24 hour period), generalized, brief

17

Complex febrile seizure

Multiple (occur more than once in a 24 hour period), focal, prolonged

18

Recurrence of febrile seizure

90% of kids have recurrence within 1 year of onset

19

Risk factors for recurrence

young age at onset
febrile seizures in 1st degree relative
low grade fever in ER
brief duration between fever and seizure

20

Epilepsy can develop from febrile seizures. The risk factors for the development of epilepsy in children with febrile seizures is:

- complex febrile seizures
- A family history of epilepsy
- Neurologic impairment prior to the febrile seizure

21

Long term management for a kid with simple febrile seizures

Do not give anticovulsants to a kid with one or more simple febrile seizures.

If the parents are very concerned, give oral diazepem at teh onset of febrile illness

22

Children with febrile status epilepticus are at risk for what

hippocampal injury and a substantial number also have abnormalities in hippocampal development

23

Focal slowing or attenuation are present in EEGs obtained within 72 hours in a substantial proportion of children with febrile status epilepticus and are highly associated with MRI evidence of Acute hippocampal injury

24

If neuroimaging is to be performed in a child, what is the preferred modality

MRI
