How is CDKL5 deficiency disorder treated?

Currently there is no cure for CDD. Patients are treated for their symptoms, not for the underlying cause of the disease. Seizure control is the primary goal for patients with CDD. There are currently companies investigating treatments for CDD including possible gene therapies.
