This collection primarily includes documents and video recordings relating to the study and diagnosis of Landau-Kleffner Syndrome. This syndrome is a rare disorder in which children lose the ability to speak and respond to language and was identified and described by Kleffner and William M. Landau, MD in 1957.
Of note are video recordings of diagnostic and follow-up interviews with a patient who was successfully treated for Landau-Kleffner Syndrome as a child (Series 2: Video Recordings, 1961-2007). Also noteworthy are correspondence and other documents relating to a symposium held in 2007 to mark the 50th anniversary of the identification of Landau-Kleffner Syndrome (Series 1: Documents relating to Landau-Kleffner Syndrome, 1957-2014).
The case of the patient interviewed in the recordings is included in Mantovani J.F. & Landau W.M. (1980). “Acquired Aphasia with Convulsive Disorder: Course and Prognosis.” Neurology, 30 (5), 524–529. In the article the patient is identified as Patient 7.
