- Brief Summary
Cluster headache is a primary headache. The chronic form of the disease is often difficult to treat. It is now considered a chronobiological disease. This chronobiological character is based on clinical, biological and radiological arguments.
This study focuses on the use of light therapy in cluster headache. Light therapy has already been used in the treatment of other chronobiological diseases, such as seasonal depression, but also recently in the therapy of other primary headaches (such as migraine). Its aim is to re-adjust chronobiological rhythms, and it therefore seems worth testing in the chronic form of cluster headache.
Light therapy is delivered to the patient using a consumer electronics device.The main objective is to evaluate the prophylactic efficacy of light therapy in patients with chronic cluster headache.
