Abstract

The Landau-Kleffner syndrome (LKS), formerly known as acquired epileptic aphasia, is a rare syndrome that typically presents in early childhood with language regression and seizures. We report a case of LKS in an 7-year-old boy who presented with aggressive behavior, difficulty in maintaining posture, and language regression. Systemic examination, including neurological evaluation, was normal. Cerebrospinal fluid (CSF) analysis and magnetic resonance imaging (MRI) were normal. Electroencephalogram (EEG) showed abnormal findings associated with generalized seizure discharge during sleep with more spikes being noted in bilateral frontal and temporal regions. LKS was diagnosed and was treated with anticonvulsants and steroids. On follow-up, the child showed improvement in maintaining posture, was able to walk independently and had improved linguistic functions. This case adds another variant of LKS to the existing literature.
