Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this project is to study the efficacy of triheptanoin oil in patients with GLUT1 deficiency syndrome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective of the study is:

\- to evaluate the capacity of triheptanoïn to improve the condition of patients with GLUT1-DS

The secondary objectives of the study are:

* to confirm the short-term safety of triheptanoïn therapy in patients with GLUT1-DS
* to evaluate the short-term effects of triheptanoïn treatment on motor function, autonomy, quality of life and clinical signs of patients with GLUT1-DS
* to evaluate the effect of triheptanoïn on brain energy metabolism using non-invasive 31P-MRS spectroscopy after activation of the occipital cortex in order to measure the levels of high-energy phosphates (such as ATP and phosphocreatine)
