Abstract
Movement disorders constitute an important and distinctive clinical consequence of
glucose transporter type 1 deficiency. Gait disturbances and dyskinesias can be present
chronically, and can fluctuate daily with fasting, exercise, and other environmental
triggers. Patients manifest an array of paroxysmal disorders often associated with
variable motor symptoms, also precipitated by fasting, exercise, and other stressors.
Ketogenic diet is the treatment of choice in this condition and can offer substantial
improvement of motor symptoms, particularly if instituted immediately after the onset
of first clinical symptoms.
