The brain of patients with cerebral ischemia is the same as that of normal people, and there is nothing abnormal. Cerebral blood supply is insufficient, but cerebral blood flow is reduced, so brain CT and magnetic resonance vibration are normal. Cerebral Doppler examination will find that the blood flow velocity of cerebral artery is slowed down, the blood flow is asymmetrical or the cerebral artery is convulsed (contracted).
Not every patient with cerebral ischemia has all the symptoms of cerebral ischemia (different symptoms at different stages of the disease), blood pressure (low or high) or blood lipid, blood sugar (abnormal), anemia, blood viscosity (thick), plus 2 13 symptoms of cerebral ischemia, plus Doppler examination results (slow cerebral blood flow, asymmetry, arterial spasm). The results of Doppler examination, combined with your mother's symptoms, can basically make a diagnosis of cerebral blood supply deficiency. As for what causes insufficient blood supply to the brain, the following tests should be done.
Most of the problems of insufficient blood supply to the brain are blood pressure (unfortunately, you didn't provide your mother's blood pressure, and many test results were not introduced by you, which made the diagnosis difficult). It is recommended that your mother go to a nearby clinic to take more blood pressure tests (because there are many reasons that affect blood pressure, only one test can't explain the problem, and it will be taken three times that day). According to the blood pressure values measured three times, comprehensive analysis and judgment), if the blood pressure is normal, go to the hospital neurology department to check blood lipid, blood sugar and blood routine (excluding anemia). Only by finding out the cause can we talk about treatment and it will be effective. Otherwise, all treatments are blind and even harmful (side effects of some drugs).
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 years of treatment and observation of patients with intractable dizziness and headache, the systolic blood pressure is lower than 1 1 omhg, and the diastolic blood pressure is lower than 70ommHg. Most patients have different degrees of dizziness and headache. According to the above standards, many patients with hypotension will be missed and misdiagnosed, and lose the opportunity of early treatment! I hope you can pay attention to this problem, because once misdiagnosed, it will cost a lot of money not to say, and more importantly, it will make people suffer and delay their illness.
Cerebral insufficiency should be differentiated from cervical spondylosis. Because the symptoms of the two are very similar, a little negligence can easily lead to misdiagnosis; But the symptoms of the two are also different, which can be avoided with a little attention.
Cervical spondylosis, obvious pain in the neck (not mild pain, especially when the head moves up and down). Five different types of cervical spondylosis have different symptoms. However, obvious neck pain is the most basic symptom of various types of cervical spondylosis. Without this symptom, the diagnosis of cervical spondylosis is difficult to establish), upper limbs are numb and weak, and radiation pain (that is, neck pain caused by radiation pain in shoulders, arms and fingers). Dizziness caused by cervical spondylosis is often related to the fixed position of the head. Due to the instability of the cervical vertebra or the compression of hyperplastic bone, the vertebral artery is locally compressed. Avoid this position, and the vertigo caused by the compression of the vertebral artery disappears. Therefore, cervical spondylosis will not cause intractable dizziness. According to your description, your mother's dizziness and headache don't seem to have these characteristics, so cervical spondylosis can be ruled out. However, a mindset has been formed in clinic. As long as there is dizziness and headache (no matter what the situation), it will be considered as caused by cervical spondylosis. I hope my answer will help your mother!
Refractory dizziness and headache is one of the persistent 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 wish your mother a speedy recovery!
