Lennox-Gastaut syndrome

Dr Henry Knipe and Dr Yuranga Weerakkody et al.

Lennox-Gastaut syndrome is a form of refractory childhood-onset epilepsy and is often accompanied by developmental delay and psychological/ behavioural problems. An electroencephalogram (EEG) often shows a slow spike and wave pattern.


It is thought to often appear between the 2nd and 6th years of life and is thereafter characterised by frequent seizures (up to 200 times an hour 4) and multiple seizure types.


History and etymology

It is named after William G. Lennox, a US neurologist (1884-1960) and Henri Gastaut a French neurologist (1915-1995) 4.
