颈椎病引起的头晕和脑部缺血引起的头晕有什么区别 吴伟 核工业四一六医院

颈椎病引起的头晕和脑部缺血引起的头晕有什么区别 吴伟 核工业四一六医院 颈椎病引起的头晕和脑部缺血引起的头晕从发病机理来说它是不一样的。颈椎病引起的头晕是因为颈椎病的原因导致颈椎这个地方有椎动脉，只要颈椎有椎动脉它左右两边一边一根，然后通过这个枕骨大孔进入颅内。它是一个大脑血供的比较重要的一个动脉，然后颈椎病引起头晕，它主要就是因为颈椎椎间关节增生或者勾凸关节增生，导致这个椎动脉受到压迫。这种头晕它和脑缺血引起的头晕不一样的地方就说它有突发性，而且它是和这个体位有密切的关系，大部分病这种头晕发作的时候是因为突然的一个转头动作，或者突然的一个低头动作，一下就头晕了。甚至有的病人因为眩晕，他会发生这个跌倒这些，但是它不会引起遗留神经症状。它一般是一过性的。然后还有的病人呢就是说他只要颈椎一活动，比如他一扭头，一旋转脖子，他出现头晕，然后他马上把脖子或者就是返回到原先的位置，他这个头晕马上就缓解了，所以它就是和体位有很明显的关系，这就是它和脑部缺血引起头晕最大的区别。 What is the difference between dizziness caused by cervical spondylosis and that caused by cerebral ischemia Dizziness caused by cervical spondylosis is different from that caused by cerebral ischemia. The dizziness caused by cervical spondylosis is due to the presence of vertebral artery in this part of the cervical spine, As long as the cervical spine has a vertebral artery, it has one on the left and right sides, Then through the foramen magnum into the skull. It's an important artery for the blood supply of the brain, Then cervical spondylosis causes dizziness, It is mainly due to the hyperplasia of cervical intervertebral joint or kyphosis joint, This leads to compression of the vertebral artery. This kind of dizziness is different from the dizziness caused by cerebral ischemia, And it's closely related to this position, Most of the dizziness comes from a sudden turn of the head, Or a sudden bow, I was dizzy. Even some patients are dizzy, He's going to fall over this, But it doesn't cause legacy neurological symptoms. It is generally transient. And then there are patients who only need cervical vertebrae to move, For example, when he turns his head, A rotation of the neck, He was dizzy, And then he immediately put his neck back in place, His dizziness was soon relieved, So it's obviously related to the position, This is the biggest difference between it and dizziness caused by cerebral ischemia.
