Dehydration and salt deficiency trigger migraines
Neurons without electrolytes in their environment cannot function. They are idle, dying, or dead—this is defined by new research just published in the Journal of Neuroscience as “brain depression”. Neurons are connected to communicate with each other. When neurons in a region don’t function, neighboring neurons try to awaken them—this is referred to as the spreading of electricity in the parts of the brain that are not in depression in the same scientific article. This is seen as aura in those with migraines in the occipital lobe of the brain. For migraines in other regions, the healthy neurons signal pain sensing nerves located in the meninges, a tissue separating the brain from the skull (there is no pain sensing nerve inside the brain). Migraine is pain signaled by pain-sensor neurons in the meninges and so the location of where we feel pain is not necessarily connected to the location that causes pain.
