We report here a longitudinal study of a 3.8 year old female child diagnosed as having Landau Kleffner Syndrome (LKS). Speech-language analysis was carried out over a two-year period while the child was on medical treatment regime. The result of the language evaluation suggests that this child demonstrated exacerbation and remission in accordance with the regime of medication. However, the recovery was significant during the exacerbation phase although not complete. At the end of the two-year period, she was found to have a lag of over one-and-half year in the language function as against the chronological age. Detailed conversational sample from the child is reproduced at the end of this paper. (Contains 3 tables.)
