What is migraine? How to use in English

The word "migraine" is believed to have originated from the Greek word "hemikrania," meaning "pain on one side of the head," which was further developed and transformed by medieval medical scholars. In the Middle Ages, migraines were often connected to mystical, supernatural, or demonic causes, leading to the term "migraine" which derived from the Latin words "miger" and "granus," meaning "to flow" and "grain," respectively. The term "migraine" alluded to the belief that migraines were a result of "black bile," a supposed fourth humor associated with melancholy and depression. This theory (known as the "humoral theory") posited that an imbalance in these bodily fluids caused various medical conditions, including migraines. The word "migraine" was subsequently used in medical literature during the Renaissance and has remained a part of the medical lexicon ever since. The modern understanding of migraines is much different from the medieval belief that they were caused by mysterious and mystical forces. Today, migraines are understood to be neurological disorders characterized by recurrent headaches and other symptoms, such as nausea, sensitivity to light and sound, and visual disturbances. In summary, the word "migraine" evolved over time, starting with references to headaches and progressing to more complex, mystical, and medical terminologies. In a nutshell, "migraine" has come a long way since its ancient Greek roots and its current meaning reflects a better understanding of the science behind this common neurological condition.
