LANDAU KLEFFNER SYNDROME
- Lennox
Gastaut syndrome - the presence of generalized tonic seizures
suggests Lennox Gastaut syndrome, focal motor seizures are rare in
Lennox Gastaut syndrome
- Epileptic
encephalopathy with continuous spike-and-wave during sleep -
although both syndromes may have progressive cognitive, behavioral
and psychiatric impairments, if acquired aphasia is the predominant
feature then a diagnosis of Landau Kleffner syndrome is appropriate
(the presence of slow spike-and-wave on EEG is not mandatory for
diagnosis)
- Language regression due to other etiologies
