Study summary

Doose syndrome is a rare epileptic syndrome that can lead to learning difficulties and a poor quality of life. The goal of this study is to evaluate the evolution of epilepsy and its consequences on cognitive development and learning issues in children with Doose syndrome.

Read the detailed description

Doose syndrome is a rare epileptic syndrome beginning between ages two and five, characterized by myoclonic-astatic seizures which can be associated with myoclonic seizures, astatic seizures, absences and generalized tonic-clonic seizures. These seizures can be difficult to treat effectively and may lead to learning difficulties. During this study, parents of children with Doose syndrome will receive a questionnaire regarding learning disabilities, quality of life and epilepsy of their children.
