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 asymmetrical (the slow blood flow on one side of the cerebral artery accelerates 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 at different stages of the disease), blood pressure (low or high), blood lipid, blood sugar (abnormal), anemia, high blood viscosity (thick), plus 2-3 cerebral ischemia symptoms, plus Doppler examination results (asymmetric cerebral blood flow velocity [fast or slow] or
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 lipids, blood sugar, blood routine (excluding anemia) and blood viscosity. If everything is normal, then do a Doppler examination, and you can basically make a diagnosis.
It is worth noting that the normal value of blood pressure in China is set too low (systolic blood pressure is 9O- 12O mm Hg, and diastolic blood pressure is 6o-80mm Hg). According to our treatment and observation of intractable dizziness and headache for many years, the systolic blood pressure is lower than 1 1 omhg, and the diastolic blood pressure is lower than 70ommHg. Most patients have varying degrees of dizziness and headache. According to the above standards, many patients with hypotension will be misdiagnosed and missed diagnosis, and lose the opportunity of early treatment! I hope you can pay attention to this problem. Because once misdiagnosed, it will waste a lot of time, and more importantly, it will delay the illness and hurt the body. Only with a clear diagnosis can the treatment be effective, otherwise all treatments will be blind and even harmful (side effects of many drugs).
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, the vertebral artery is locally compressed, and the vertebral artery is relieved. Avoid this position and dizziness disappears. Therefore, cervical spondylosis will not cause intractable dizziness. According to your description, your dizziness doesn't seem to have these characteristics, so you can rule out cervical spondylosis. However, a clinical mindset has been formed. As long as there are symptoms of dizziness and headache (no matter what symptoms), it will be considered to be 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).
I hope to find out the cause as soon as possible and restore health as soon as possible!
