Recurrent Seizures
- Main
causes

disease
- Tumors, especially rapidly growing
ones, occupy space and increase
intracranial pressure
- Perinatal hypoxia

ones, occupy space and increase
intracranial pressure
- Pediatric disorders
- Rapid increases in
body temp
causing febrile
seizures

- What is a
seizure?
- disturbance in the normal
electrical activity in the brain;
can stay in one area or spread
to other areas of the brain
- Triggers include
strobe/flickering lights
or the occurrence of
small fluid & electrolyte
imbalances.
- Occurs more

held
- Large jerking movement
of major muscle group
- Status
epilepticus
- Medical
emergency
- Continuous seizure
activity that can lead to
coma & death

- Febrile
- Determining cause of recurrent
seizures is important for
appropriate drug selection
- can develop into
- Epilepsy
- central nervous system (neurological)
disorder in which brain activity becomes
abnormal, causing seizures or periods of
unusual behavior, sensations, and
sometimes loss of awareness.
