The brain of patients with cerebral ischemia, like normal people, has no pathological changes. Insufficient cerebral blood supply only reduces cerebral blood flow, so it is normal to do brain cT and MRI vibration. When you do cerebral Doppler examination, you will find that the cerebral blood flow is slow and asymmetric (slow blood flow on one side of the cerebral artery speeds up the blood flow on the other side). Therefore, there is bilateral cerebral artery blood flow velocity asymmetry) or cerebral artery spasm.
Not every patient with cerebral ischemia has all the symptoms of cerebral ischemia (there are different symptoms in different stages of the disease), blood pressure (low or high), blood lipid and blood sugar (abnormal), anemia, high blood viscosity (concentration), plus 2-3 cerebral ischemia symptoms, plus Doppler examination results (asymmetric cerebral blood flow velocity [fast or slow]
Cerebral blood supply deficiency is common in abnormal blood pressure (unfortunately, the specific blood pressure is not introduced). I suggest you go to a nearby clinic to take your blood pressure several times. If your blood pressure is abnormal (low or high), then your discomfort is caused by abnormal blood pressure. If the blood pressure is normal, then go to the hospital to test blood lipid, blood sugar and blood viscosity. If everything is normal, a brain Doppler examination will basically confirm the diagnosis.
Cerebral blood supply deficiency should be differentiated from cervical spondylosis, because the symptoms of the two are very similar, and a slight negligence can easily lead to misdiagnosis; But the symptoms of the two are also different, and you can tell them with a little attention.
Cervical spondylosis, neck pain (not mild pain), especially when the head moves up and down. The symptoms of five different types of cervical spondylosis are different, but obvious neck pain is the most basic symptom of all types of cervical spondylosis. Without this symptom, the diagnosis of cervical spondylosis is difficult to establish.
In addition, cervical spondylosis can also cause numbness, weakness and radiation pain in upper limbs (that is, pain in neck, shoulders, arms and fingers caused by radiation). Dizziness caused by cervical spondylosis is often related to the fixed position of the head. Due to the instability of cervical vertebra or the compression of hyperplastic bone, vertebral artery is locally compressed. If you avoid this position, the vertebral artery will be released and dizziness will disappear. Therefore, cervical spondylosis will not cause intractable dizziness. According to your description, your discomfort doesn't seem to have these characteristics, so you can rule out cervical spondylosis. However, a mindset has been formed in clinic. As long as you feel dizzy (no matter what symptoms), you will think it is caused by cervical spondylosis, which is a misunderstanding. This situation is too common in clinic, and it is easy to mislead patients!
Cerebral blood supply insufficiency has been one of the chronic diseases in medicine for many years. Due to the limited space, it is not convenient to elaborate one by one. If you are interested, you can check my Baidu space, which has a detailed explanation (1, why dizziness and headache are difficult to treat. 2. Life and self-care guidance for patients with dizziness and headache).
May you find out the cause as soon as possible and get well soon!
