Benign myoclonic epilepsy in infancy

 

Presentation

This is a rare, self-limited epilepsy in infants with mainly myoclonic jerks.

Toddlers (range 3m to 3y) manifest with brief and random head drops followed by extension of arms. No other seizure types seen.

 

There is usually f/h/o epilepsy disorder.

 

The word ‘benign’ is used because the seizures are usually easily controlled with medication and the developmental outcome of the children is usually normal.

 

Investigation

EEG shows generalized spike-wave discharges, particularly when tired or sleepy.

Photosensitivity may be seen.

 

Management

Treatment is indicated & good response to Valproate, Levetiracetam or Clobazam.

 

Seizures resolve in a few years, usually before 8y age

Some children display behavioral, learning or other developmental disorder.
