Pathophysiologic Difference between Migraines, Cluster Headaches and Tension-Type Headaches
    The key pathophysiologic difference between cluster headaches, migraines and tension-type headaches is that cluster headaches can be a genetic or disturbed circadian disorder; migraines are neurovascular disorder, whereas tension-type headaches can also be a result of chemical effects of nitric oxide. As mentioned by Donnet (2015), if a distant relative possess cluster headache, the risks increases to 14-39 times, of the activation of gray matter of posterior hypothalamus, which in turn, dominates the autosomal chromosomes thus causing this disease, apart from the reasons being activation of autonomic nervous system, increase in mast cells, disturbed circadian cycle and release of histamine.
    On the other hand, as stated by Weaver-Agostoni (2013), in case of migraine, neuronal waves initiate from the brain, which spread to the blood vessels, within few minutes. The excited reaction in the form of aura begin from the cerebral cortex, which are mainly due to the trigeminal nucleus present at the brainstem, thus, causing migraine. The pathophysiology of tension-type headaches is different from these because sustained pericranial myofascial inputs cause excitements in the central nervous system, which are mainly due to the reaction of nitric oxide to the brain, thus causing this disorder (Waldie, Buckley, Bull & Poulton, 2015).
