Treatment for Cluster Headache
Light therapy for Cluster Headache primarily modulates melatonin secretion and circadian rhythm regulation by stimulating the suprachiasmatic nucleus through retinal photoreceptors. By exposing patients to specific wavelengths and intensities of bright light, typically in the morning, the treatment aims to reset disrupted circadian rhythms and potentially reduce the frequency and intensity of cluster headache episodes. The intervention works by suppressing melatonin production and synchronizing the hypothalamic-pituitary-adrenal axis, which is believed to be dysregulated in cluster headache patients.
