Page "Epilepsy" Paragraph 47

: The course of Dravet syndrome is highly variable from person to person.

Seizures begin during the first year of life and development is normal prior to their onset.

In most cases, the first seizures occur with fever and are generalized tonic-clonic ( grand mal ) or unilateral ( one-sided ) convulsions.

These seizures are often prolonged, and may lead to status epilepticus, a medical emergency.

In time, seizures increase in frequency and begin to occur without fever.

Additional seizure types appear, most often these are myoclonic, atypical absence, and complex-partial seizures.
