What are the main symptoms of cerebrovascular disease?

The symptoms of cerebrovascular diseases caused by different reasons are not the same.

Below are the clinical manifestations of two different types of cerebrovascular diseases, ischemic and hemorrhagic.

1.The first type is ischemic type, and most ischemic cerebrovascular diseases suddenly develop rapidly, causing damage to the brain within a few minutes.

Patients often have unclear consciousness, coma, and numbness, some of which can cause depression and emotional loss of control. Depending on the affected brain tissue area, different neurological symptoms may also appear. For example, ischemic cerebrovascular disease can cause brain edema and swelling, causing serious neurological damage, which can even be fatal.

Clinically, the symptoms of ischemic cerebrovascular disease are mainly divided into two types(symptoms of cerebrovascular diseases):

  • One is acute ischemic cerebrovascular disease. Acute ischemic cerebrovascular disease is relatively common, with sudden onset and rapid development of symptoms. It is often unilateral neurological dysfunction, which often affects the upper limb first, and then progresses on the ipsilateral side. It continues to expand in a few hours or a day or two, without causing headache or fever. The progression of the disease is sometimes severe, sometimes relieved, and some may continue to worsen.
  • The other is transient ischemic attack. Transient ischemic attack starts suddenly, lasts for 2-30 minutes or longer (rarely more than 1-2 hours), and then subsides, leaving no lasting neurological disorders; During the whole episode, the consciousness is preserved. If it lasts for several hours, even if there is no lasting neurological disorder left, the lesion site may be seen on the brain CT performed afterwards.

2.The second is hemorrhagic cerebrovascular disease.

Cerebral hemorrhage occurs suddenly, often accompanied by headache, and then continues to occur, such as weakness, paralysis, numbness, loss of speech and vision, and disturbance of consciousness. Nausea, vomiting, convulsions, and loss of consciousness often occur within a few minutes. Doctors often make the diagnosis of cerebral hemorrhage without giving any examination to patients.

The clinical symptoms of hemorrhagic cerebrovascular disease are also mainly divided into two types:

  • One is intracerebral hemorrhage. Intracerebral hemorrhage starts with a sudden headache, followed by neurological disorders. Small intracerebral hemorrhage can cause focal neurological disorders, and its clinical manifestations are similar to ischemic stroke. Massive hemorrhage in the brain can produce hemiplegia of the body and dysfunction of the cerebellum or brainstem, which is manifested by the deflection of the eyeball to the same side of the hemorrhage site of the brain or paralysis of the muscles controlling eye movement, and the pupil narrowing like a needle tip. The patient may have coma, nausea, vomiting, nonsense and twitching. More than half of the cases with a large amount of intracerebral hemorrhage died within a few days. Among the survivors, with the gradual absorption of the hemorrhage, the patient’s consciousness recovered and the neurological disorder gradually alleviated. After recovery, the patient may have neurological dysfunction, such as speech difficulties.
  • The second is subarachnoid hemorrhage. Patients with subarachnoid hemorrhage may have acute and severe headache, and headache may also be the only symptom. The body temperature may rise within the first 5-10 days. Patients may have different degrees of neurological disorders or changes in consciousness, slow response or dementia. When the blood is mixed with cerebrospinal fluid, it will stimulate the meninges, promote the increase of cranial pressure, cause headache, vomiting, dizziness, and the change of pulse and respiratory rate. Occasionally, the patient will have convulsions and neck stiffness, but when the patient has cerebellar herniation, moderate to severe neck stiffness can occur.
