What condition is characterized by speech difficulties and seizures that develop in childhood?

Landau-Kleffner Syndrome is a condition that primarily affects children and is characterized by the loss of acquired language skills (aphasia) along with the onset of seizures. This syndrome typically manifests between the ages of 3 to 7 years, where children may experience a sudden or progressive decline in verbal skills after a period of normal language development. Seizures associated with this syndrome can be diverse, including both focal and generalized forms.

The relationship between speech difficulties and seizures is a hallmark of Landau-Kleffner Syndrome, making it distinct from other conditions listed. While Epileptic Encephalopathy can also involve cognitive and developmental issues alongside seizures, it does not specifically revolve around language loss as a defining feature. Wernicke's Encephalopathy is related to thiamine deficiency and presents with a different set of neurological symptoms, primarily affecting cognitive function and ocular motor control rather than speech in childhood. Olivopontocerebellar Atrophy is a degenerative condition that affects movement and coordination, not predominantly speech or seizure activity. Thus, the defining characteristics of Landau-Kleffner Syndrome make it the most accurate answer for the condition described.
