 めまいの症状はさまざまで、ぐるぐる回っているようなめまい(回転性めまい)、からだがふらふらする、船に揺られている感じ(浮動性めまい)、目の前が暗くなり気を失うこともある、頭から血の気が引く感じ(失神性めまい)などに分けられます。
http://viagraonline-4rxpharmacy.com/  からだの平衡感覚をつかさどる器官は、内耳(三半規管、耳石)、前庭神経などの末梢器官と、脊髄、脳幹、小脳、視床、大脳皮質などの中枢器官に分けられ、前者の異常によるめまいを末梢性めまいと呼び、後者の異常によるめまいを中枢性めまいと呼びます。末梢性めまいは回転性めまいが多く、中枢性めまいは浮動性が多いといえますが、末梢性めまい=回転性めまい、中枢性めまい=浮動性めまいとは言えません。また、失神性めまいは、循環器系の異常(心不全、起立性低血圧、高血圧症、不整脈、血管迷走神経反射、貧血)などにより中枢器官の血流低下により起こります。
 末梢性めまいを起こす病気は、メニエール病、前庭神経炎、突発性難聴、聴神経腫瘍、薬剤性などのめまいなどがあります。
 中枢性めまいの原因としては、脳卒中(脳梗塞、脳出血など)、椎骨脳底動脈循環不全、良性発作性頭位変換性めまい、脊髄小脳変性症、脳腫瘍などがあります。
 めまいの診断で、重要となるのは、発症の仕方(突然か、徐々にか)、症状の持続時間、随伴症状(難聴、耳鳴りなどを伴うか)です。難聴や耳鳴りを伴う場合は、末梢性めまいの可能性が高いと言えます。
 めまいの治療で、緊急性があり命に関わる病気は、脳卒中や脳腫瘍など脳に関わる病気です。めまいが出た場合は、一度頭部MRI、頭部MRA、頚部MRAなどの検査をお勧めします。
 また、末梢性めまい、中枢性めまい、循環器系の異常による失神性めまい以外に、心因性めまいが挙げられます。心因性めまいは、めまい全体の約30%と言われており、以上の病気に当てはまらない場合、心因性めまいを考慮する必要があります。
