What are the symptoms of cerebral ischemia

Cerebral ischemia is a relatively common acute cerebrovascular disease, commonly known as "mini-stroke". Generally, patients will suddenly become ill, and if treated promptly, they can recover within 24 hours. However, the disease will recur, often putting patients and their families in a tense atmosphere, and placing a heavy burden on both patients and their families. Symptoms of cerebral ischemia include the following:

1. Acute cerebral ischemia

Sudden, transient, focal neurological deficits that resolve within 24 hours without sequelae;

The main symptoms of focal neurological deficits are:

(1) Hemiplegia, hemiplegia, decreased sensation, visual impairment, and bulbar palsy;

(2) Dizziness, headache, tinnitus, black spots in front of the eyes, facial numbness, weakness in the limbs, coughing when drinking water, and slurred speech.

Many of the above symptoms may last for a few minutes or hours before completely returning to normal. In a few patients, they may last for more than ten hours, but all return to normal within 24 hours.

2. Recurrent cerebral ischemia symptoms

Repeated attacks of dizziness, heaviness, headache, irritability, tinnitus,

Insomnia, dreaminess, memory loss, lack of concentration, forgetfulness (such as not being able to remember recent events), etc.

Situation occurs.

3. The age of onset is mostly over 50 years old, with a history of heart disease and atherosclerosis.

Transient ischemic attack, abbreviated as TIA, is also called transient ischemic attack or mini-stroke. It refers to brain dysfunction caused by a decrease in cerebral blood flow in a short period of time. Each attack lasts for a short time, usually a few seconds, minutes or hours, and no longer than 24 hours. It is often overlooked because the symptoms come and go quickly, and leave no sequelae after recovery. In fact, although the symptoms of TIA are mild, the consequences are serious. If not treated in time, according to statistics, about 25% to 40% of patients will suffer from severe cerebral infarction within 5 years, threatening the patient's life. Therefore, medical scientists often regard it as a precursor or danger signal of cerebrovascular disease.
