Here is a synopsis:

LANDAU-KLEFFNER SYNDROME / ACQUIRED CHILDHOOD EPILEPTIC APHASIA:

Very rare disorder. Typical profile: normal development and age
appropriate language first 3-7 years; Loss of receptive language
while retaining some expressive language; "Telegraphic" speech--few
verbs; Suspicion of deafness; Child frustrated, puzzled by change
in himself; Autistic-like behaviors; normal or above normal
non-verbal IQ score; abnormal EEG, with or without seizures. Some
practitioners suspect that some cases of Childhood Disintegrative
Disorder or "late outset" autism may be Landau-Kleffner Syndrome.
